A downloadable Aseprite script

Grid2Size is a collection of two Lua scripts for Aseprite that either double or half the size of the Grid.

What It Does:

  • Grid2Size will resize your current Grid by either doubling it (Grid2Double.lua) or halving it (Grid2Half.lua).
  • The Scripts are provided separately to allow users to give each action separate Keyboard Shortcuts.
  • Grid2Size will not resize your Grid any further if either the Grid width or height reach the value of 1.
  • The Grid size is doubled by a factor of 2; and halved by a factor of 2, rounded down.
  • Reasonably, Grid2Size won't work if you are not working on a Sprite.

Install instructions


  • In Aseprite, go to File > Scripts > Open Scripts Folder. This should open an Explorer window on <Aseprite program folder>/scripts.
  • Copy the files Grid2Double.lua and Grid2Half.lua to this folder, close Explorer and restart Aseprite.
  • The next time you open Aseprite, the Scripts will be available for you to use in the Scripts menu.


  • While editing a Sprite, go to File > Scripts > Grid2Double or Grid2Half, and they will automatically double or halve the grid size.
  • You can also bind the scripts to different Keyboard Shortcuts by using the available option in the Edit menu. Read the Aseprite documentation for more information.

This is super handy. Changing the grid size in most editors is a pain.

doestn work on latest aseprite beta

I'm working on Aseprite v1.3-beta6-x64 and it works just fine—I actually use it constantly while making pixel art so I would have found a bug by now, I'm sure. I'll need more information about this if there's anything actually wrong with it. Please let me know if you can.
