How do I increase sprite area?

Hello, I'm developing a game where you touch a sprite and then it falls. Recentlly I noticed that it's touching area is too small. How can I increase it without changing the sprite size?

The touching area is the sprite's collision polygon. You can change that in the sprite editor. It might be too small or a weird shape. If you want to be able to touch outside of the sprite's bounding box then you could use a larger invisible sprite pinned to the sprite or "pick nearest" with a distance check.
