Engine snippet

Press “Count frames” first.

Memory = width × height × 4 bytes (RGBA8) per frame and sheet. Engine values: Godot 4 SpriteFrames H/V + fps/loop; Unity Sprite Editor slicing + Animation clip sample rate; RPG Maker charset cell math. Verify the grid visually in the Sprite Sheet Slicer before importing.

How to use

  1. Type sheet + frame size (or press “Use demo sheet” / pick a PNG to auto-fill sheet size — measured locally, never uploaded).
  2. Set margin/spacing if your sheet has borders or gutters; pick fps + engine.
  3. Press “Count frames” — columns, rows, total, memory + engine values appear above.
  4. Copy the snippet or download the TXT/JSON, then verify frames in the slicer before import.

FAQ

Does this upload my sprite sheet anywhere?

No. Measuring uses a local file input read inside this tab. Typing numbers touches no file at all. Open the network panel while counting — zero uploads, zero third-party requests.

What do I get out?

Columns, rows, total frames, RGBA memory per frame and sheet, plus engine setup (Godot H/V/fps/loop + GDScript; Unity grid + sample rate; RPG Maker cell note) with TXT and JSON downloads.

Why not just use a paid sprite tool?

PixZels ($15, 3D workflow, 78MB), Memao ($12.99, locked art) and Top Down Sprite Maker ($10, 12 ratings) per the 2026-09-25 slicer card bundle installs and art libraries. Counting frames needs none of that — this page does the math free.
