It's...something. Sadly, it's not quite making sense. Suppose I was preparing a sprite sheet using GIMP, and I wanted sprites that were more or less the same size as the default RPG Maker VX ACE characters. What dimensions would I want to use?
The main problem is that Ace accepts any size of sprite - and there are several oversized monster sprites even in RTP.
That said, basic sprite and grid size of the RTP is 32x32 pixels. And now you have two options:
1) you want to make a single sprite(like the monster or door sprites in RTP), then
- picture size is 3x4 grid elements or (3x32)x(4x32) pixels or 96x128 pixels
- save the picture as a PNG including transparency and a filename stat starts with $ (like the large monster spritesheets)
2) you want to make a full spritesheet (like the actor and NPC sprites in RTP), then
- picture size is 4x2 sprites or 12x8 grid elements, total size is therefore 384x256 pixels
- place eight different sprites in groups of 3x4 on that
- save the picture as a PNG including transparency and without a $ in front of the filename, like the actor spritesheets
If you use different sizes and naming conventions, then Ace will split the spritesheets into pictures in a different size than 32x32
