Pixel Circle / Oval Generator

Nice. I like the javascript effects.

If anybody else is interested in a 3d version, I have one over at:

http://oranj.io/blog/voxel-sphere-generator-77

I think it should have an option to download a picture of it and a zoom out button when for my mob arena im working at 223 X 223 its very hard to have to scroll and I end up printscreening it

Is there a download to this?

New version is so much faster, thanks!

how do i see my result, theres no where to hit enter or something to send my numbers through or something.

It should appear instantly as you change the value. If you could provide some information on what browser and version you are using I can look into the problem.

I have been using this generator for nearly a year on my phone with no issues. I have been making semi circles in my castle that step up each level so it has a colisseum look. However, every time I load this page, in the box were width and height are, all that's entered in there is NaN. I can't add to or delete it. Rendering this generator useless to mw now, and there are no other generators that work for me. Marvellous.

Having a few issues with this program. Trying to create a sphere to encapsulate the spawnable area for hostile mobs (wiki: 128 radius from player). So I doubled the radius to 256 then generate a sphere based on that. Before I started I plotted out 6 points all starting out from the 0/0 axis in the end (which I removed all end stone). Markers were placed exactly 128 bocks up, down, left and right so it covers all X/Y/Z directions. When building the sphere I noticed that the 2D sides did not meet up with my (triple checked) reference points mentioned above. The sphere generated by this program seemed too big ( by quite a sizeable margin I might add). Thinking it was my error I recounted the chart...three times...rebuilt...three times...but still no joy. This is a great generator to make spheres...not denying that....but for really technical mapping it's fairly inaccurate in "true to size" builds. Sorry to rain on your parade but thinking I might add this footnote for other builders like myself thus saving them time. But hey....if your just after a good looking sphere this is the program for you.

Your math is simply bad. If you have a radius of 128 the diameter in pixel universe will be 255, not 256, because one of those blocks is the center. That is your issue.

My circles are mathematically correct. The math in fact is particularly simple.

While I love this generator the png downloads will not open and a preview of them says the file contains nothing :/, love to get some feedback to resolve this problem if anyone else encounters or has encountered it

Thank you for the heads up. I'd heard this from a couple people but was never able to reproduce it until today. It ends up it was a race condition, so it was dependent on the speed of your machine.

I believe I have fixed the issue. You may need to clear your browser cache to get it to work.

How big would i make a circle around a 50*50 build?

You'd want to do some simple trigonometry.

So to find the diagonal of a triangle or a square, you use the pythagorean theorem:



Since we're solving for c we want:



So entering your 50's into that we get



That rounds up to so 71, but to nicely wrap your 50 which is an even number we'd want to round up to a 72x72 circle.

I hope that helps ?

Love how the file was just called soup,lmao

lol, that was a bug. I fixed it. Thanks for the heads up.

Truth is, I just want to be part of the 10 year comment archive! Great tool btw, I have been using it for years, mainly in minecraft builds. Thanks for keeping it online.

Honestly, I'm pretty bummed I had to limit them. The full list is massive!

Google complained the page was taking too long to load for people on slow connections which lowered my ranking.

I've a set max limit right now + I added a flag for comments I thought were important to always show. I should add a button to "show all" comments.

Is there a way to see how many blocks to fill in the circle?

Set the circle to "filled". The number of blocks will be displayed in the "blocks" section.

Does anybody know why exporting a circle with a radius of one hundred and fifty-two (152) as a PNG magically changes the width & height of the image to three thousand (3,000) pixels?

The PNG download simply converts the currently displayed output from the Pixel Circle Generator into a PNG image, including grid lines and spacing between pixels. The output is not just a pixel circle - and the overall size of the generated output is therefore equal to the output displayed in the generator.

If the scale slider is set to its maximum value, the output will be 3000 × 3000 pixels.

bro is answering people on the same day for 12 years straight
insane dedication to own's project

All the comments go directly to my phone ;) Makes it easy.

I used this to make a circle but when I tried to create a sphere it didn't match in size.

Making a good sphere is actually more difficult than it seems. My friend Ray actually has a pretty nice sphere generator. He was actually the first comment on this page.

https://oranj.io/blog/VoxelSphereGenerator

I wished there was a 3D one like this so I can make sandy checks house.

If you check the very first comment on this page, at the very top, my friend Ray posted a link to his 3D version way back in 2012.

https://donatstudios.com/PixelCircleGenerator#Comment3891

how do I know how many blocks it takes to go from the center to the perimeter diagonally

Hah, that's... a surprisingly complicated question. Curious why you need the diagonal specifically?

I'm following a comment from a couple of years ago where you explained the error in someone's math. I want to make a large, odd-numbered circle With a diameter of 257. I have my center point at 129 blocks from the edge of each cardinal direction. When I try to build the outside of one quadrant of the circle, I usually end up 1-2 blocks short of the cardinal direction I'm building toward. For example, if I place my center block at 0,0 and my southern-most point at 129, 0 and my eastern-most edge at 0,129 the edge of the circle usually ends up 1 block short at x:1 y: 128 despite triple-checking my build. Is it a simple error of placing an incorrect block or is my math not translating to a circle made of cubes? Thanks!

So 129 is the correct center point if you're intending to build on blocks 1 to 257 inclusive.

If you're starting building on block zero, you'd have to shift it over by 1, so 0 to 256 has a center point of 128.

What you may want to try is place your center brick, then build the center lines ✛ out from it, e.g. 127 out in each direction from the center block. Then build all four of the ends sort of ☩ and work your way in like that one step of the edge at a time all the way around the circle.

That method will help guarantee your circle ends up with the correct boundaries.

Bro straight up used algebra to help someone on his website. Abolsute W owner. Btw website is really amazing so thank you for taking the time to make it all those years ago.

Oh and I also read through every single comment lol

Dude, you don't even know. The comments on here are limited to showing the most recent 100 + comments I mark "always show".

There's currently 582 total. I'd love to show them all but I had to limit it because I was getting dinged by Google for the site taking too long to load on slow mobile phones.

I've been going to add a "show all comments" button for a while now… I should get around to that.

How do you make the circle in minecraft

You are on the page with the answer, my friend.

Is there some kind of bug with this website? I'm trying to make a 320 diameter circle but no matter what I do its always 319 blocks in diameter

Usually this off by 1 is just misunderstanding the size of the circle you actually need to fill the desired space.

Let's say you wanted a circle that spans from x coordinate 5 to 10. 10 - 5 = 5 so you think you'd want five but in reality you actually want six.

If you think about it, you want your circle to cover the blocks 5 6 7 8 9 10 so that is a 6x6 circle and not a 5x5. If you are just subtracting coordinates, you need to add 1 to the dimensions.

All that is to say my guess is you need a 321x321 to fill the space you are trying to fill.

i wanted to make a dome and at first i used this to make a cricle after that i went to some other site so i would see how i should build the dome and it made diffrent circle and now im confused because i dont know if my dome can now be done with circle from this site

Generating a sphere or dome is actually subtly different than a circle in surprising ways. If you check out my friend Ray's generator it's a better tool for that purpose.

https://new.oranj.io/sphere

been using this for years, it's great and has been an amazing help.

ALso i have a suggestion please add a darkmode theme and maybe other colors

This is really helpful for my project! However, I would like to suggest a few things. Please add the diameter of the circle, or the length of blocks from the center. Also, adding a sequence of blocks would make it even better! Especially when working with large scale projects, just like SparkSan's comment.

This size you enter *is* the diameter.

I think it would be convenient if fractional widths and heights were allowed. I don't know if there's some algorithm that relies on them being integers... a priori, it doesn't seem necessary to constrain them to integers.

Also, I noticed that the way it decides whether to include a block in the circle or not is based on whether the center of the block is within the (mathematically accurate) circle. (Or, I think it is, unless I did my math wrong.) Options to include a block in the circle if the block is at all in the circle (check corner closest to center) or at all outside the circle (check corner furthest from center) would be nice - maybe I'll try forking the repo to see if I can add that.

I've made a pull request to add fractional radii and the option to check whether blocks are in the circle at blocks' corners (either the closest or furthest) instead of their centers. The latter works best for even-centered circles, where the part of a block closest to the center of the circle is always guaranteed to be a corner, not the center of a block or the center of an edge.

I'll probably use it myself (with the closest corner option) for a circular perimeter. Makes it feel slightly more correct, like "literally everything within this distance is mined down", instead of "everything within this distance (up to half a block) is mined down".

For small circles, checking corners gives results that look too square and less circle-like than checking the blocks' centers, but for massive circles, it's hardly noticeable.

So, I have bad vision, The red is hard for me to count and see, it doubles and disappears in my vision and trying to make bigger projects like I have been using it for makes it rough on my eyes I was wondering if you could ever implement an option for different color sets, for me a reverse of the colors or just a deep color would help my vision immensely. Thank you so much for your time, I hope you have a great day or a great night!

Marie, that is a great suggestion!

I will definitely look into adding color options for accessibility!

Is there any version of this for a hex grid? I haven't been able to find a single one that can generate perfect circles like this but on a hex grid.

Interesting, I don't know of any. It wouldn't be hugely difficult to build. Is there a game that would be useful for?

so i love this website best thing in the world for my 1:1 scale builds but i wanted to make sure im right in assuming if i want a circle or oval 3000 pixels wide id need to input 1500 correct? as thats why ive been doing and want to make sure i dont need to restart my current build

Nope, if you want a circle that is 3000 across, you would enter 3000. The values to the input are the diameter, not the radius.

To see this directly in action, try a small size like 5 × 5 and see that it is 5 across and 5 tall.

This thing helped me again, so many years later. My Lighthouse has a beautiful foundation now. Bookmarked ages ago, always surprised when the bookmark still works.

I am delighted to hear that you've found this useful over the years!

Frankly, if this link stops working, I am probably dead.

I actively maintain multiple websites that have been online continuously since 2001. I have no plans on shutting anything down, even if the usage falls to zero.

Great tool! I wonder if there can be a thickness slider/number input for those who wants to build circles thicker than one block…

Is there a way to add multiple circles to see what it would look like with a circle/oval inside of another circle?

i use this for terraria lol

ive been using the generator for YEARS and thank you for making all my circle bases actually look like circles

W website, i use it all the time

Goat jesse donat

I've used this generator for years and it is so good, big circles, useful tools and bearable mobile use but as others have said it would be cool to have a number sequence generate for how blocks you should place. E.g a 5x5 circle would be,3, 2, 1, 2, 3, 2, 1, 2 but most people leave out direction with that it would be more like 3, 2, 1, L, 2, 3, 2, D, 1, 2 (L being left and D being down starting from the bottom and going anti clockwise). I have no clue how hard this would be to code but it would be a useful feature given it's what I already do. Also for the square select could you add a multi pick choice like a line at a time for bigger circles, don't have to it'd just save me like a minute. Great site, great ovals (great feature). I love it

honestly amazing website , used it for ages and multiple projects , one note is how hard it is to see the blocks/count them , if you could allow different colours or something like that it would be great and easier for the colorblind to see , other than that incredible work

It would be super useful if we could associate a single block with X and Z coordinates and the tool could let us know the bounds of the circle. Could be a center block or an outside block for reference.

Nice website bro

ok but how is this still getting comments this was made 13 years ago

lol, what do you mean? Because people still playing Minecraft 15 years after it came out.

I must say: This generator is splendid and also damn you replying fast to comments it seems like.
it spares me the troubleshootin of making the blueprint myself

Every single comment goes straight to my phone. Makes it really easy for me to respond quickly.

just realised that been using it for 5 years pretty much, time flies

used this for a minecraft end hub, made a 207x207 circle

I used this for a round LEGO® creation and it proved very useful. Thank you very much!

I'm using this generator for a hardcore base in the end. Really useful when it tells you the amount of block and stacks you need. (Help I'm making a 361x361 circle and 319x319 circle)

I know they say imitation is the sincerest form of flattery or whatever, but you're not me ;)

i am you

Oh no!

this is great! I wish I could zoom out more cause I'm building a capital city and need a 600-600 wall and cant see the whole thing, other than that the way it tells me how many blocks I need is great!

this is great! I wish I could zoom out more cause I'm building a capital city and need a 600-600 wall and cant see the whole thing, other than that the way it tells me how many blocks I need is great!

This has been a major help for the last year or so constructing roundabouts in Minecraft. Thanks

i was the person who talked about the hardcore end base (im not impersonating lol, someone else did the same too) but i cant thank you enough this has been so much easier

I would love to be able to add concentric circles to see how different sizes look nested!

I just couldn't leave this page without adding my own comment to this decades long thread. And thank you for the tool! I've used it many times in my builds and am always somewhat surprised to find it still here after so long. Building a HUGE castle right now and need more towers. lol.

Absolutely what i needed thanks for this

I have a idea that could really help those of us that are making large-scale builds who use your site. Currently, I'm in the first steps of making a mega-city build, and I wanted to make a 514x514 circle, which is 32 chunks in diameter - 2, so the cardinal block placements would be outside of the chunk. Following the generator block for block with such a large generation is rather annoying (especially since I keep messing up by 1 or 2 blocks in circle length). It would be very helpful if you could create a toggleable 16x16 "Chunk" subdivider, where when you input a big enough circle length, you could see the "chunks" that the circle would fill, and you could use those chunks as a guide. Additionally, you could also add settings to the subdivider that can change position from the center of your circle by 16 blocks in each direction (since not all of us build exactly by the block).

Again, this is just an idea. You ultimately have the power, but I, as well as a good amount of us would be grateful if you did!

Would you be able to include a track transition curve? https://en.wikipedia.org/wiki/Track_transition_curve

THANKS FOR MAKING THIS AWSOME WEBSITE

Jeez, this website is old. The oldest comment was made 4,956 days ago. that's over 13 years and 7 months...

That's just the first comment on *this page*. The very first comment on any post is 5,890 days old - 16+ years.

https://donatstudios.com/JSONP#Comment1

I don't even play Minecraft lol but I use this in wplace all the time, thanks

god damn 16+ years is crazy

Wow you've been active on this site for a while, Jesse G. Donat. You were the 9th person to ever comment on this page. respect

lol, it's my website dude 😎

I'm planning on making a gold farm in the Nether on my main world on Bedrock edition for my Xbox 1. Any tips you guys can give me on making it?

That's really cool! I'm glad that you made this website, It's really helpful. Anyways, i'm trying to learn how to industrialize my main world. So far in that world everything is manual, tedious, and takes ages. Do you know what automated farm is the best for collecting lots of non-flammable blocks?

Nice circs bro

this website is very useful. Thanks for this. You helped alot of people making builds with blocky things.

Ending up finding this, its great for any block type game where you are trying to build a circle, like Space Engineers. I can actually finally build half of the things I wanted to build without it looking like a square. Thank you for this splendid website

Just wanted to say Happy New Year, and thank you for the almost 20 years of support to help people make circles in a cube based game! You should be put in the MC Hall of fame lmao

hey uhh is there a way to select the thickness of the circle? i want to make a gold farm

This helped me in so many projects I had during the past 3-4 years

What do you mean by "thickness" of the circle? Do you mean, like, three-dimensionally thick or just a circle with the entire volume filled?

For some reason when i tried putting in my 49 by 49 circle and then building it it didn’t work it wasn’t big enough what do i do about that

W site helps me alot with minecraft building when it comes to building circles i just cant make my own circles in minecraft. W site

To Steve:

What helps me make MY builds easier is breaking them up into quarters. For example, when I was making the blueprints for a 23x23 circle, it helped me to remember the length. First start with a central point, then you start making the 4 "arms" in a "+" pattern. In your case, each arm should be 24 blocks long with a central block to make the X and Y axis arms total up to 49 blocks. Does this help

so helpful

You are very welcome! It makes the entire build much easier to only memorize a quarter of it, since the entire circle is just the same quarter used four times.

If I have a pathway that's 4 blocks wide going straight through the middle should I need to subtract that from the length. I have 82 for example

also im not that good at math so if i would make sphere around a 5x5x5 build how big would the dimensions of the sphere be

pretty useful for Minecraft, I have used this countless times and I would donate if I had decent money. The least I can do is thank you!

Hi l want to use this how do l use it

how has this been a thing for so long? Good job lol

Incroyable cela m’ aide beaucoup dans mes constructions

To Mia,

Basically, the width affects the X-axis and the height affects the Y-axis. In the render box, the border options determine how thick the circle is. whether it's completely filled, or if only the perimeter is.The "Scale" slider beneath that just zooms in or out. And the details box gives you the specifics about how many blocks it will take to make the circle or oval. I hope this was helpful to your question!

this is so good thank you

How can I make a 20*20 cirkle in my Stark Tower.

I gotta say been using this for years and its always worked for me i appreciate it i just got done having to build a 201 by 201 so it comes in handy not having to try and free build it 😂

Minecraft

Simple and perfect and never needs to change love that

I used this to create a border around an ocean monument so I could drain it. Very helpful!

Love how the comments are like a timeline from 2012 to like 3 days ago and also love this thing just drained my first monument

You don't even know! There are currently over 700 comments and I'm only showing the latest 100 and a handful I flagged as important to always show.

does someone know how many blocks i have to place until i reach the center?, im already so confused

Hiii i love it!

Great site really easy to understand and verry helpfull was having a hard time befor and now i just worry to build thanks a bunch

How do I put this in the game I’m confused

This has been my goto for years at this point, but I only just noticed there are comments. Your tool has made my builds so much better, thank you!!!

Not a complaint, but for people like with bad vision, and trying to do a 1000x1000 circle, it would be nice to have a number next to the blocks telling me how long the specific segments need to be, if you could in any way do this, I would really appreciate it

Just stumbled across this after using it for years — still the best circle generator out there. Jesse, your dedication to replying to almost every comment for over a decade is legendary.


One small request: any chance you could add an option to show the block coordinates (like offsets from center) when hovering over the preview? Would make translating to large-scale builds way easier. Either way, thanks for keeping this alive!

Trying to count out sections on that center line on my phone with two damn near identical shades of gray is making me go insane. I’ll be in Arkham Asylum before I finish my build.

Handy tool. It would be very helpful if you could add coordinates. For example, the use would enter the coordinates of the center block, and the output would show the coordinates of each perimeter block, perhaps with a mouse hover or by toggling them for individual blocks.

This has been very helpful for building since I stumbled across it, but how do I use it to make spheres? Or is there a different website that makes spheres? Also like that you can change the color of the red blocks to mark what you have placed.

Love it just wish it showed how long each half is cause of if it is an even number or odd number across cause that could affect if there is a center block or 2 center blocks

Bonito para Minecraft

I agree with Dave's comment from 4/7/26 - I would love the ability to put my center coordinate in and have the tool generate the perimeter coords in relation to it. Admittedly, I have next to no understanding of the coding that goes into this, and therefor probably don't have a clue what I'm asking for in terms of workload. Regardless, this is by far the best tool I've found for mapping circles in MC, and I'm deeply grateful to your commitment to it over the years.

You should be able to put a circle inside of a smaller one, that would be cool

Thanks for this! Im playing Stardew Valley and this helps inmensely with planning. There are probably so many grid-based games apart from Minecraft that this has ended up being useful for in these years

Is there a way you can add numbers in the middle of each "section" of cubes to show how many is in that row/column? It is very hard to count a lot of cubes at once when doing long stretches. Something like this? below.

https://i.imgur.com/Hp2LVML.png

You are awesomesauce for making this

This is such a useful tool! I use this for Minecraft builds a lot. Thank you :D

Sem sombra de dúvidas um dos melhores sites que auxiliam algo no Minecraft, simplicidade perfeito!

Great tool with no lag.

Been using this tool pretty consistently on and off for over 12 years at this point! Love it!

If I did a 22x22 circle and I wanted to have a circle around it but how big would the circle have to be?

I'd just like to say i love this - I've used it a lot, for both Minecraft and other things, and it hasn't been blocked on my school chromebook yet :)

This is really great! I'm using it in a platformer game to make a level that is a recreation of the Earth

im building a circle base in minecraft but i dont know if i should build it with a diamater of 1001 or 999

Such a lifesaver. Been building Wembley Stadium and because of how big it is I needed circular corners. Could you add a way to only view a quarter of the circle?

She Pixel on my Circle 'til I Generator

Does anyone know how i would make a circle with a 40 block diagonal in between the center and the "corner"?

This is a great project! I've just been using gimp's circle tool then trying not to go insane finding the center and trying to count the pixels, and this project blows that method out of the water!

To answer a few questions I saw frequently in the last 100 comments (even though they were also answered by Jesse):
- if you want to create a sphere, go to http://oranj.io/blog/voxel-sphere-generator-77
- if you want to build a circle around a build that has a greatest measurement of X, the diameter of the circle you need will be sqrt(2X) rounded up to the nearest odd number if X is odd and even number if X is even.

I hope that this helps everyone who doesn't want to just read all the visible comments like I did.


P.S. Jesse, you should definitely add a 'See All Comments' button.

P.P.S. Hope you're doing alright, Jesse. Haven't seen any replies since March
