How to plan an oval
An oval is a circle stretched in one direction, so it has two sizes: the width (left to right) and the height (top to bottom, or front to back on the ground). Set both above. The red dashed lines cross at the centre of the oval, and every row is a mirror image on either side of them.
- Set the width and height. Odd numbers give a single centre block; even numbers give a centre between blocks.
- Pick Thin, Thick, Filled or a custom wall width.
- Open "Row by row block list" to see which columns to fill on every row. Build the top row first and work down to the middle, then mirror it.
- Tap blocks as you place them, and copy the link to keep your exact oval.
Good oval shapes for builds
- Arenas and stadiums: about 5 by 3 looks right, for example 51 by 31.
- Ponds and lakes: a filled oval, then knock a few edge blocks off so it looks natural.
- Oval windows: small sizes like 5 by 7 or 7 by 11 with the Thin style.
- Egg shaped domes: use the sphere generator with a different height to stretch it up.

Questions
How do I make an oval in Minecraft?
Untick Keep it a circle, then set a different width and height. The grid shows every block of the oval, with counts for each row, so you can build it row by row from the centre lines.
What is the biggest oval I can make?
Width and height can each go from 1 to 512 blocks.
Is an oval the same as an ellipse?
In building terms, yes. The generator draws a true ellipse: each block is tested at its centre against the ellipse with the width and height you chose.
Can I make an oval with a thick wall?
Yes. Choose Thick for a gap free wall, or Wall width to set the thickness in blocks.
