How to Select Rectangular-Shape Geometry Options in Photoshop CS6

By Barbara Obermeier

In Photoshop CS6, you can select various Rectangular-shaped geometry options using the Gear Icon in the Options toolbar. Here are the Geometry options for the rectangle and rounded rectangle shapes.


  • Unconstrained: When you select this option (the default), Photoshop defines the size and proportions of the rectangle while you drag.

  • Square: Select this button to constrain the shape to a perfect square. (You can also hold down the Shift key to do the same thing on the fly.)

  • Fixed Size: This option lets you draw rectangles only in fixed sizes. Specify the exact size by entering a width and height.

  • Proportional: This option lets you define an aspect ratio, or proportion, for the rectangle. Type 3 into the W box and 4 into the H box to constrain yourself to drawing any size rectangle with fixed proportions in a 3:4 ratio.

  • From Center: Select this option to expand the shape from the center point you click.

  • Align Edges option: This option snaps the edges of a rectangle or rounded rectangle to the pixel grid of your canvas. This option is available to all of the shapes.
