How to add Sprite with correct size?

Sup guys! I’ve already added the sprites with the necessary materials to the scene and trying to handle click on sprites. My sprites is a circle with serial number. But sprite is so big and bigger then sprite material that leads to wrong click coordinates.
For example: I have click handler which change cursor to pointer when you are on it. But cursor changes when you are a little to the right or top. How to solve this issue ?
