How to Spell 15

The number 15 is written by combining the word “five” with the word “teen,” which indicates a number after twelve. The correct spelling is f-i-f-t-e-e-n. It’s straightforward since, like “fourteen,” the base number “five” does not change when forming the word.

Spelling Details and Variations

The ordinal form of the number 15 is spelled as “fifteenth.” To form this, you simply add “th” to the end of “fifteen,” creating the word “fifteenth” for the numerical form “15th.”

When to Spell Out 15 and When to Use the Numeral

Typically, numbers less than one hundred are spelled out in text. This means that you will often spell fifteen instead of writing the numeral “15,” particularly in non-technical and narrative writing. The exception to this rule is when using the number in technical contexts or when it includes decimals or is part of a larger figure, such as 115 or 15.6. Always spell out numbers that begin a sentence.

Practical Examples in Sentences

  • My niece is turning fifteen years old next month.
  • There are fifteen students in my yoga class today.
  • The recipe calls for fifteen grams of sugar.
  • I ran fifteen miles this week to train for the marathon.
  • When I was fifteen, I learned how to drive a car.

Special Considerations

In cases involving money, “fifteen dollars” can be spelled out if the amount is a round number without cents. When cents are included, it is typical to use the numeral version, written as “$15.99,” for example. In scientific and technical contexts, you should use the numeral form when it is accompanied by a unit of measurement, such as “15 mL.”


The number fifteen holds its relevance in mathematics, literature, and everyday counting. Understanding when to spell it out and when to use the numeral is key to mastering its usage in English. Whether for financial transactions, educational settings, or casual communication, knowing the nuances of number representation is an invaluable skill.
