Page units represent sizes or distances on the printed page. In an office layout with a drawing scale of 2 cm = 1 m (1:50), centimeters are the page unit. In a drawing scale of 1/4' = 1', inches are the page unit.

Shapes are designed to work with the template they come with. Building plan shapes, for example, work best with scaled drawings, while flowchart shapes work best with unscaled (1:1) drawings.

When you drag a shape onto a drawing page, the shape resizes to match the drawing scale. If the scale of the shape is much larger or much smaller than the scale of the drawing page, the shape is not resized. Consider using another shape designed to work with a scaled drawing.
