I've always been amazed those small blades can make enough lift in the thin martian atmosphere

Here's a picture of a to-scale model to emphasize what the other comment is saying - Ingenuity isn't that small, and also remember that Mars' surface gravity is only about 40% of Earth's.

The blades total length are 1.2m. Not that small really.
