29 block circle in Minecraft (radius 14)
A 29-block-wide circle takes 80 blocks for a 1-block outline and 665 to fill it. Go around each quarter in runs of 7·3·2·1·1·1·2·3·7. The centre is a single block, because 29 is odd.

| Diameter | 29 blocks (radius 14 from the centre block) |
| Outline, thin wall (diagonal steps) | 80 |
| Outline, thick wall (no diagonal gaps) | 112 |
| Filled disc | 665 |
| Flat edge on each side | 7 |
| 5-high tower wall | 400 · 6×64 + 16 |
Rule: a block counts when its centre lies inside the circle, the same grid the game uses. Checked 21 Oct 2026.
How to build it
- Mark the centre block. Count 14 blocks out from the centre block in all four directions and mark those four points.
- Place the four flat edges of 7. Centre each flat edge on one of the four points: 3 blocks either side of it.
- Fill each corner with 3·2·1·1·1·2·3. After each run, step one block diagonally inward and place the next run. Do the same in all four corners.
- Repeat for each layer. A straight wall is the same ring on every layer (a 5-high wall takes 400 blocks). A dome or sphere shrinks the ring as it goes up.
All 29 rows, north to south
Each row lists its runs of blocks from west to east; "2-2" means 2 blocks, a gap, then 2 blocks.

Questions
How many blocks is a 29 block circle?
80 blocks for a 1-block outline with diagonal steps, 112 for an outline with no diagonal gaps, and 665 for a filled disc.
Should I build 29 or 28?
29 is odd, so the circle has one centre block: doors, beacons and pillars line up with the middle. 28 has a 2×2 centre instead.
How many blocks for a 29 sphere or dome?
A hollow 29 block sphere with a 1-block shell takes 2,106 blocks; a hollow 29 dome (15 layers, open at the bottom) takes 1,073. Plan them layer by layer in the sphere generator or the dome generator.
Thin or thick outline?
A thin outline (80 blocks) steps diagonally, so mobs and water can slip through the corners. A thick outline (112 blocks) adds a block at every step, which makes a sealed wall.
