In Illustrator, you can change the eraser size. To do this, open the Preferences window and select the Eraser Size tab. There you will find a list of eraser sizes. You can choose one of these sizes to use when erasing text: Small: This is the default size for most erasers. It is small enough to easily erase small areas but large enough to cover most text. Medium: This size is larger than Small but smaller than Medium-sized erasers. It covers a larger area but may not be as easy to erase smaller areas. Large: This size is larger than either Medium or Large-sized erasers and is the largest available. It covers most text and is the best choice for covering very large areas.
