Overworld sprites larger than the standard size?

I wanted to use these as overworld sprites, despite them being twice as big as the standard RPG Maker MV sprite size. When I put them into the game, this happened:

(Ignore the weirdly sized [SV] Battler sprite, it works fine)

Does anyone know how to fix the "character" sprite so the sprites I made work? Thanks!

In the name of the file itself, just put this at the beginning (and after that, all you want) : !$

It works! Thank you so much!

It's normal ^^ I have been in the same situation at the beginning. Do ! when the file is higher than the normal resolution and $ to signify that the file is for one character only (3 frames large 4 frames height).

@Nantas @otamaru
you got the ! wrong, and that will cause you problems.

! is the indicator for a object sprite (like doors, chests, etc), it has absolutely nothing to do with file size or file structure.

There are two changes that are caused by the !, both of them on the ingame parts.
First, it means that the event sprite will be placed exactly on the grid - normal NPC sprites are displaced 8 pixel up to give them the appearance of walking inside a tile instead of on its borders, but a door needs to be fitting to the grid to look normal (you don't have holes at the bottom of doors).
Second, it means that some minor functions intended to showcase character interaction are changed and disabled.

So a character sprite should never have a ! applied to its sprites filename.

Okay thank you @Andar for explaining it ; I have thought based on the experience I had and I didn't absolutely understand the thing, but now it's good ! Thank you very much !
