Changing Measurement Units

Written by Allen Wyatt (last updated February 7, 2024)
This tip applies to Word 2007, 2010, 2013, 2016, 2019, and 2021

Word allows you to modify your work environment extensively. One of the changes you can make involves the default units of measurement used in dialog boxes and on the ruler. By default, Word uses inches, but you can customize the program so it will use centimeters, picas, points, or millimeters.

To change the default measurement units, follow these steps:

Display the Word Options dialog box. (In Word 2007 click the Office button and then click Word Options. In Word 2010 or a later version display the File tab of the ribbon and then click Options.)
Click Advanced at the left side of the dialog box.
Scroll through the available options until you see the Display section. (See Figure 1.)

Figure 1. The Display section of the Advanced options in the Word Options dialog box.

Using the Show Measurements in Units Of drop-down list, select the units of measurement you want used by default.
Click on OK.

@Ronald On my computer (Windows 10 Region Canada) if I set the units to cm in the options, then that's what appears as the units in the Custom Margins dialogue box.

If your system is defaulting to inches, then maybe you need to look at the regional settings in Windows

You can switch the measurement unit, but that doesn't change the default sizes and spacings.
I have word set to use A4 paper and dimensions in cm but it still defaults to 1" margins (2.54cm) and 1/2" indents (1.27cm).
With the entire world except the USA and UK now using the metric system, isn't it time Word makes that the default?

I have recently switched to Office 365. This tip supposedly applies to that version, but I can't find the Options dialog box anywhere. Snap shot attached. (see Figure 1 below)
