Changing Measurement Units

by Allen Wyatt
(last updated July 3, 2018)


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:

  1. 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.)
  2. Click Advanced at the left side of the dialog box.
  3. Scroll through the available options until you see the Display section. (See Figure 1.)
  4. Figure 1. The Display section of the Advanced options in the Word Options dialog box.

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

Being able to use metric units of measure to specify paper sizes is only half the solution.

I also want to specify type sizes in millimeters, but have been unable to find a way to do that in MS Office.

There is a Germain digital typesetting standard (DIN 16507-2), but most programmers seem to ignore either this standard or the English Metric Unit ( and assume that the entire the world uses Imperial units of measure.

Any suggestions?

I have changed the default measurement setting to centimetres and use centimetres throughout all documents. Why then do the default normal, narrow, wide etc margin measurements still appear in imperial measures? How can they be removed?

2016-03-17 13:15:39


Hi. My MS Word on my Mac is always in the unit of centimeters. I keep changing it to inches but when I close the Word and open again, it's back to centimeters. What do I do???

2015-02-22 20:17:17


Thankyou so much!
