Calculadora gratuita de hoja de sprites para juegos indie 2D.
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.
Entrada
32×32, 8 frames, 12 FPS, RGBA 32-bit.
Salida
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.
