16 in Roman numerals is XVI, built from X + V + I (X = 10, V = 5, I = 1), which add up to 16.
How 16 is written in Roman numerals
The number 16 is written XVI in Roman numerals. Roman numerals use seven letters — I (1), V (5), X (10), L (50), C (100), D (500) and M (1000) — combined from largest to smallest, with subtractive pairs such as IV (4) and IX (9).

|---|
| X | 10 | 16 | 6 |
| V | 5 | 6 | 1 |
| I | 1 | 1 | 0 |

Frequently Asked Questions
What is 16 in Roman numerals?
16 in Roman numerals is XVI. Reading it left to right gives X (10) + V (5) + I (1) = 16. The number below it, 15, is written XV, and the number above it, 17, is written XVII.
How do you write 16 in Roman numerals?
Write 16 as XVI, combining X (10) + V (5) + I (1). Roman numerals are built by taking the largest value that still fits, writing its symbol and subtracting it, which reduces 16 in 3 steps: X leaves 6, V leaves 1, I leaves 0. Every symbol keeps the same value wherever it stands, so the order is fixed and XVI is the only standard spelling of 16.
What are the Roman numerals either side of 16?
Either side of 16 the Roman numerals are XV for 15 and XVII for 17, with XVI between them. Those three numerals are 2, 3 and 4 letters long, so the length changes as you count. Roman numerals have no digit positions, so each step can rewrite the numeral rather than bumping a single digit.
How is XVI read out loud?
XVI is read as the number it stands for, sixteen, and never letter by letter. Roman numerals are a way of writing values rather than a separate set of names, so the spoken form is the same whether the page shows 16 or XVI. A chapter or volume numbered XVI, for instance, is simply chapter sixteen.
