The ruler

The horizontal top ruler appears by default in all letter documents. You may also choose to display a vertical ruler, using the View Control dialogue box described below.

In documents where no rulers are displayed (usually spreadsheet documents) you can turn on the rulers using the View Control dialogue.

As well as measurement markings the top ruler shows you the left, paragraph and right margins and tabs. Use the status line to help you.

The ruler is marked out in inches, millimetres or centimetres. Change the unit of measurement using the commands on the Extra menu.
