# Eraser

### Eraser

Select the Eraser tool, and click anywhere you want to erase.

The eraser size is directly related to the grid size. Try temporarily changing the grid [Units](https://chrispalmeri.gitbook.io/really-sketch/options/units) if you want to make the eraser bigger.

### Undo

The Undo button may be a better option in many cases. It will undo the last thing that was drawn. You can use it repeatedly to undo more than one thing.
