I'm new to Illustrator and now I want to create a rounded rectangle with 10px 0px 10px 0px radius for corner, how can I do that?


This only works in Illustrator CC or newer.

  1. Draw a rectangle
  2. Use the Direct Selection Tool A (White Arrow on Toolbar)
  3. Pick one corner
  4. Use the little circle that appears to create a radius

You can double click the circle to enter exact figures:

In CS6 and earlier:

There is no dynamic way to do this as far as I know. The easiest way to do what you want is to use the rectangle tool, and shape it to the size you want.

Then go to

Appearance Window > Stylize > Rounded Corners > 10px

and then hit

Object > Expand Appearance

and zoom into the top right corners and adjust the nodes so that the corner ends up square and repeat with the other one.

  • In newer versions they created a dynamic way. If you're using Illustrator CS6 or earlier than you'd be correct that there isn't. – Ryan Aug 4 '14 at 14:01

    for earlier versions I would recommend the "Round any corner" script: theitbros.com/adobe-illustrator-cs6-round-one-corner where you can select as many corners as you want and round them independently. – Luciano Aug 4 '14 at 15:59

In CC 2018, you must first select- with the direct select tool or lasso- only the point or points associated with the the corner you want to work with. Then you can use the widget to adjust that corner's radius independently. Note that with an already rounded corner there are 2 associated points. The good news is that any corner in any shape can be adjusted now.
