Determine radius of a rounded rectangle


I have a psd that has rounded rectangle. I need to create a new rounded rectangle with the same radius. How do I determine the radius used on that said rounded rectangle?

I feel like this is such an awful question but thanks in advance for answering.

Select your rectangle with the direct selection tool (enter image description here), so you can see the vector nodes. Then zoom in CMD+= until you can see the pixel grid.

Now you can count the number of pixel rows between the two nodes, this is the value you need to use for your new rounded rectangle radius.

In this example the radius is 10px.
