You can draw shapes to the exact size you want by using the Draw Shape tool in Visio. 

You can create your own custom shapes by using the rectangle, ellipse, arc, freeform, and pencil shapes in Visio.

Your browser does not support video. Install Microsoft Silverlight, Adobe Flash Player, or Internet Explorer 9.

If you want to be able to apply fill colors to your new shape, you need to create a closed shape. If you use the Rectangle tool or the Ellipse tool, you get closed shapes automatically. By default, closed shapes are filled with a solid color.

A closed rectangle and an open triangle

In this example, the rectangle is a closed shape because it is filled with a solid color. You can tell that the triangle is not closed because it is not filled with a solid color and you can see the drawing background through the shape.
