Spell out numbers less than ten in body copy. Ten and above get numerals, unless they’re the first word in a sentence.

Ordinal numbers (e.g. “first,” “31st”) follow the same rule.

However, always use numerals when writing:

  • Dates
  • Dimensions
  • Percentages
  • Price
  • Sums of money
  • Temperature
  • Time of day
  • Timestamps
  • Years

In headings, titles, calls to action, and other very small spaces, use numerals if it saves space or has more of a visual impact.


  • One, two, three, four, five, six, seven, eight, nine, 10, 11, 12
  • First, second, third, fourth, fifth, sixth, seventh, eighth, ninth, 10th, 11th, 12th
