If you wonder when to write a number in Arabic numerals and when to spell it out openly, guess no more.
MS Word has a grammar setting that lets you know whether you are doing it correctly or wrong.
The general rule is this:
1) Spell out all single-digit numbers.
2) Use Arabic numerals for all numbers with two digits or more.
CORRECT: “She is only three years old.”
INCORRECT: “She is only 3 years old.”
CORRECT: “She is 33 years old.”
INCORRECT: “She is thirty three years old.”
Let MS Word remind you the rule automatically.
- Click MS Office button.
- Click Word Options button to display the Word Options dialog box.
- Select Proofing.
- In the Proofing pane, make sure the “Mark grammar errors as you type” check-box is selected:
- In the Proofing pane, click the Settings button to display the Grammar Settings dialog box.
- Scroll down to the Style group of check-boxes.
- Select the Numbers check-box.
- Click OK to close the Grammar Settings dialog box.
- Click OK once again to close the Word Options dialog box.

As a good practice, higher the number, better it is to express it with Arabic numerals since it’s easy to read the text of big numbers and comprehend them easily.
