Minecraft Circle Generator: Pixel Circle and Oval Chart
Choose a size and a style, then read the chart from the top row down. It shows every block, the count for each row and the total you need. Tap blocks as you place them to keep your spot, and save or print the chart when you are happy with it.
Tap a block in the chart to mark it as placed. Downloads and prints show the plain chart without marks.
- Total blocks
- 56
- Size
- 21 × 21
- Style
- Thin
Width 21 is odd, so the center line runs through the middle column (column 11). Height 21 is odd, so the center line runs through the middle row (row 11). The middle of this chart is a single center block.

How to use the generator
Pick Circle for a round shape or Oval to set width and height separately. Choose a style and read the chart from the top row down. The number at the end of each row is how many blocks go in that row, and the table under the chart lists every run so you can build row by row.
- Thin draws a one-block outline, thick closes the corner joins, and filled keeps the whole disc.
- Bold lines every 5 or 10 blocks help you count across a big build.
- Tap a block to mark it as placed; Clear marks starts again. Marks are kept only while the page is open.
- Use Zoom to make large charts easier to read. The chart scrolls inside its own box, so the page never gets wider than your screen.
How the circle is calculated
The chart uses one rule, the block-center rule. Lay the blocks on a grid, find the ideal ellipse that touches the edges of the box, and keep a block when its center lies inside that ellipse. Thin keeps only the kept blocks with an open side next to them; thick also keeps blocks that touch the outside at a corner; filled keeps all of them.
Other generators may round differently or use another outline rule, so a chart from a different site can differ by a block here and there. Both are valid builds; this page applies the same rule every time and every chart is symmetric left to right and top to bottom.
Odd and even sizes
An odd width has a single center column, which is handy for a doorway or a beacon line. An even width has two center columns, so the middle is a 2×2 block when the height is even too. The note under every chart tells you which one you have.

Choosing a size
Count the space you have, then pick the width that fits. A circle that is 21 blocks across needs 21 blocks of room in both directions. If you are working next to a wall or a path, check the total before you gather materials: a thin 21-block circle is a one-block ring, while the filled version is a full disc and needs many more blocks.
Printing and saving
Download PNG saves the chart as an image for a phone or a second screen. Download SVG keeps the lines sharp at any size. Print or save as PDF opens a page with only the chart, which also works for saving a PDF from your browser.
Other shapes
Use the oval, arch and size chart pages for stretched circles, vertical arches and a printable sheet of common sizes. The sphere, dome, cylinder and cone pages build on the same rule layer by layer.

A few helpful answers
Before you begin.
Is this an official Minecraft tool?
No. It is an unofficial fan tool and has no connection to Mojang or Microsoft. The name appears only to say what the charts are for.
How does the circle generator decide which blocks to use?
It keeps a block when the center of that block lies inside the ideal circle or ellipse that fits the box. Thin, thick and filled then decide which of those blocks are shown.
What is the difference between thin, thick and filled?
Thin is a one-block outline where steps may touch at corners. Thick adds the corner blocks so each block shares a side with the next. Filled has no hollow middle.
Why is the center one block for some sizes and four for others?
An odd size has a single center column or row. An even size has two, so an even circle has a 2×2 block in the middle.
How large can the circle be?
Up to 200 blocks wide and 200 high. Use the zoom control for large charts; the chart scrolls inside its box.
Can I keep track of the blocks I have placed?
Yes. Tap a block to mark it and watch the placed counter. The marks are not saved, so they reset when you close or reload the page.
Does the site store my sizes or charts?
No. The charts are drawn in your browser and nothing is uploaded or saved. Save a PNG or SVG if you want to keep one.
