How to Change Eraser Size in Adobe Illustrator

If you want to transform a shape by swiping over, the Eraser tool is the go-to. However, you often need to change the eraser size based on the shape you work on. 

For example, if you make the eraser bigger, you can have smoother edges. On the other hand, a smaller eraser allows you to work on details.

Some of you might’ve already tried changing the stroke size but saw no changes in the eraser size. That’s the wrong way to go because the eraser doesn’t have strokes.

The Eraser tool in Adobe Illustrator doesn’t work the same way as the Eraser in Photoshop, in which you could remove anything you erase. In Adobe Illustrator, the eraser is a vector editing tool that only works on paths that contain anchor points

So how does it work?

In this tutorial, you’ll find two quick and easy ways to change the eraser size in Adobe Illustrator.
