16 in Roman Numerals = XVI
16 in Roman numerals is XVI. It is ten, then five, then one, added straight across with no subtraction anywhere.
What is 16 in Roman numerals?
XVI is X (10) + V (5) + I (1). Largest first, then down.
It is the same shape as VI with an X in front of it, which is the general rule for turning any single-digit numeral into its teen equivalent up to XVIII.
How XVI is formed
Reading left to right, 16 breaks into these additive parts. Each Roman symbol is added in turn to reach the total.
X + V + I = 10 + 5 + 1 = 16.
Why 16 is written XVI
Sixteen is worth reading next to fourteen. XIV and XVI use nearly the same letters but the I moves, and moving it changes the value by two. That single position is the difference between a subtraction and an addition, and it is the most common source of misread numerals in the teens.
Where 16 in Roman numerals is used
- Regnal names: Louis XVI of France was deposed in the Revolution and executed in 1793, and Benedict XVI gives the numeral a twenty-first-century papal example.
- Milestone birthdays: A sixteenth birthday is styled XVI on invitations and cake toppers often enough that it is one of the more requested teen numerals for engraving.

- Super Bowl XVI: Played in January 1982, the first championship won by the San Francisco 49ers.
Common mistakes writing 16 in Roman numerals
- XIV is wrong. That is fourteen. Moving the I in front of the V subtracts it instead of adding it, a difference of two.
- IXVII is wrong. Not a valid construction. Subtraction happens inside a single pair, never across the whole numeral.
