Stack Calculator · Updated August 6, 2026
Minecraft pixel art stack calculator.
To calculate stacks for Minecraft pixel art, divide the block count by 64 and round up. BlockArtLab's CSV export includes pre-calculated stack estimates for every block type.

How BlockArtLab calculates stacks
When you convert an image, BlockArtLab counts each block type and divides by 64:
- White Concrete: 342 blocks → 6 stacks (384 blocks, 42 extra)
- Black Concrete: 256 blocks → 4 stacks
- Light Blue: 189 blocks → 3 stacks (192 blocks, 3 extra)
The CSV shows: block name, exact count, and stack estimate.
Why bring extra?
- Miscounts happen — especially on large builds
- Some blocks break instead of dropping
- Creeper accidents destroy sections
- 10% extra is a safe buffer
