Kostenloser 2D-Pixel-Art-/Indie-Game-Rechner für Sprite-Sheets.
Use before exporting from Aseprite, Photoshop, or Krita. Catches VRAM problems before they show up as crashes on mobile.
Unity's sprite packer reports final sizes after import; this tool predicts them before.
For N frames at W×H pixels, the calculator finds the grid (cols × rows) whose total sheet is closest to square — a GPU-friendly layout.
VRAM footprint = sheet width × sheet height × (bit depth ÷ 8). It assumes uncompressed RGBA by default.
Animation duration = frame count ÷ FPS.
No — the grid assumes packed frames. Add 1–2 px of bleed manually in your sprite tool to avoid sampling artifacts.
GPU-friendly: power-of-two dimensions when possible. The grid finder targets near-square sheets.
It multiplies the total pixel count of every frame by the bytes per pixel implied by your bit depth; for example, 32-bit RGBA uses 4 bytes per pixel. The result is uncompressed memory, so on-disk PNG files will be much smaller.
Higher bit depth stores more color and alpha detail per pixel but doubles or quadruples memory use compared with indexed or 16-bit formats. For pixel art a lower bit depth or indexed palette can cut VRAM dramatically with little visible loss.

Ausgabe
Sheet: 128×64 (4 cols × 2 rows). Duration: 0.67 s. VRAM: 32 KB.
Square-ish grid pack: 4 columns × 2 rows = 8 frames in a 128×64 sheet. 128 × 64 × 4 bytes = 32,768 bytes = 32 KB uncompressed.
