Hello,
Light : A light weapon is small and easy to handle, making it ideal for use when Fighting with two Weapons.
Heavy : Small creatures have disadvantage on Attack Rolls with heavy Weapons. A heavy weapon’s size and bulk make it too large for a Small creature to use effectively.
I'm not sure it works exactly like this in the game (I didn't really tried) but this is how it should according to D&D.
