35 block circle in Minecraft (radius 17)
A 35-block-wide circle takes 96 blocks for a 1-block outline and 973 to fill it. Go around each quarter in runs of 9·3·2·1·1·1·1·1·2·3·9. The centre is a single block, because 35 is odd.

| Diameter | 35 blocks (radius 17 from the centre block) |
| Outline, thin wall (diagonal steps) | 96 |
| Outline, thick wall (no diagonal gaps) | 136 |
| Filled disc | 973 |
| Flat edge on each side | 9 |
| 5-high tower wall | 480 · 7×64 + 32 |
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 17 blocks out from the centre block in all four directions and mark those four points.
- Place the four flat edges of 9. Centre each flat edge on one of the four points: 4 blocks either side of it.
- Fill each corner with 3·2·1·1·1·1·1·2·3. 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 480 blocks). A dome or sphere shrinks the ring as it goes up.
All 35 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 35 block circle?
96 blocks for a 1-block outline with diagonal steps, 136 for an outline with no diagonal gaps, and 973 for a filled disc.
Should I build 35 or 34?
35 is odd, so the circle has one centre block: doors, beacons and pillars line up with the middle. 34 has a 2×2 centre instead.
How many blocks for a 35 sphere or dome?
A hollow 35 block sphere with a 1-block shell takes 3,098 blocks; a hollow 35 dome (18 layers, open at the bottom) takes 1,569. Plan them layer by layer in the sphere generator or the dome generator.
Thin or thick outline?
A thin outline (96 blocks) steps diagonally, so mobs and water can slip through the corners. A thick outline (136 blocks) adds a block at every step, which makes a sealed wall.
