Rulers

You can work with rulers to have a visual representation of the current dimensions.

 Rulers are only displayed for orthographic views (top, left, right, etc.) and display the current Model Space or Paper Space units (see Space Units).

Tip: Another handy visual aid, which can be used in tandem with rulers, is the grid. See Grid.
