Game sprites
Classic sprite sizes are 16x16 (small items, icons), 32x32 (characters) and 64x64 (large characters, portraits). Convert so your grid lands on these dimensions, then scale in-engine.
Craft patterns
Perler/Hama pegboards are 29x29 beads, so use multiples of 29. Cross-stitch on 14-count Aida: a 100-stitch width is about 18cm. Keep craft grids between 29 and 100 cells per side.
Minecraft and map art
A Minecraft map is 128x128 blocks. For wall art, 50x50 is a manageable build. Set the pixel size so the grid matches your target block count.
Social media
Instagram downscales to 1080x1080, so export a square PNG at a moderate whole-number scale. Use the same grid and palette across a series for a consistent feed.
- Sprites: 16, 32, 64
- Crafts: multiples of 29, up to ~100
- Minecraft map: 128x128
- Social: 1080x1080 export
Frequently Asked Questions
What is the best pixel size for a 32x32 sprite?
Set the pixel size so image width divided by pixel size equals 32. For a 256px-wide image, that means pixel size 8.
Should the grid divide evenly?
Yes, preferably. If the image size is not a multiple of the pixel size, the last row or column of blocks will be clipped. Crop to a multiple first.
How big should I export?
For games, export at scale 1 and scale up in-engine. For sharing, export at a scale that gives a comfortable viewing size (4-10x).
