Round One Side of a Rectangle in Photoshop (Edit Individual Corner Radius)
Photoshop CC lets you precisely round rectangle corners directly and non-destructively. You’ll draw a shape, open Properties, and edit all corners together or unlink them to round just one corner—while preserving the radiuses when scaling.
Step-by-step instructions
Draw a rectangle shape
Select the Rectangle Tool (U) and drag to draw your rectangle.
In the Options bar, ensure the tool is set to Shape (not Pixels).
Open the Properties panel
Go to Window → Properties to reveal shape settings.
Locate the corner radius controls at the bottom of the panel.
Adjust all corners together
Drag any on-canvas corner widget or enter a value in Properties to round all corners uniformly.
Scale the shape to confirm the corners remain consistent and non-distorted.
Round a single corner
In Properties, click the chain link icon to unlink the corners.
Edit only the target corner’s radius (via its field or on-canvas corner widget).
Edit multiple shapes at once (optional)
Alt-drag (Windows) / Option-drag (Mac) the shape to duplicate.
Select multiple shape layers and adjust the corner radius in Properties to update them simultaneously.
