Use the Rectangle tool

The Rectangle Cc294968.ba1bf876-250a-4b92-9c85-a370408f394d(en-us,Expression.10).png tool lets you create rectangles and squares.

To create a rectangle

  1. In the Toolbar, select the Rectangle tool.

  2. In the document, drag out a rectangle. The points where you pressed and then released the mouse button determine the size of the rectangle.

To create a square

  1. In the Toolbar, select the Rectangle tool.

  2. Hold down the SHIFT key when you drag. This constrains the shape to form a square.


If you hold the ALT key when you drag, the rectangle or square is centered on the point where you first clicked.

Rectangles created in Microsoft Expression Design usually have sharp, 90-degree corners. However, you can also easily create rectangles and squares with rounded corners.

To adjust the radius of corners

  1. Either select a rectangle object on your page, or, in the Toolbox, select the Rectangle tool.

  2. In the Properties panel, in the Edit Rectangle category, the Corner Radius slider is displayed. Drag the slider up or to the right to increase the value of the radius, or drag it down or to the left to reduce the value. You can also click the slider and type a numeric value.

The roundness value is specified as a measurement. For example, a Corner Radius of 10 px is a corner that appears like a quarter of a circle that has a radius of 10 pixels.


You can change the Corner Radius setting before you create the rectangle, or after you draw the rectangle.

Expression Design creates rounded corners by placing Bezier points on the rectangular path. If you change one or more of those nodes, the shape is no longer a rectangle object and so the Corner Radius option no longer appears in the panel.

When you create smaller rectangles, it may be important that the edges are as sharp as possible. Expression Design provides an antialiasing setting for rectangles.

To set rectangle antialiasing

  1. On the Edit menu, point to Options, and then click General.

  2. On the General panel, under General, in the Rectangle antialiasing list, select either Crisp or Smooth. This setting applies to all rectangles in the document.
