Character sprite size

Hello. I've been planning my character WAD but I don't know what size my character's sprite (for gameplay sprites) should be. Can someone help please?

I've read the character WAD tutorial and the FAQ but it doesn't say anything about it.

SRB2's Sonic size is something like 32x64 if I remember right. But you can give any size to your character.

OK, thank you. :)

The bounding box that makes up the player's collision has a radius of 16 units (total width of 32) and a height of 48 units (32 units if spinning). Sprites are generally slightly larger than that, though, since it looks a bit weirder to have a solid area outside of the player's sprite than it does to have a small non-solid area on the edges of the sprite. You can open players.dta in any WAD editor (make a copy and experiment in that, so that you don't render the game unplayable) for a good reference as to sprite sizes.
