How to read the chart

Find the number in the left column and the numeral is beside it. The third column shows how the numeral is assembled from place values, which is the quickest way to learn the pattern.

Clicking a number opens a page for that number alone, with the full step by step working, the number in words and answers to the questions people ask about it.

The seven symbols

Every numeral in this chart is built from I (1), V (5), X (10), L (50), C (100), D (500) and M (1000). There are no others in standard use.

A symbol may be repeated up to three times. V, L and D are never repeated, because two of them would always be better written as the next symbol up.

Frequently asked questions

Why is 4 written IV and not IIII?

Standard Roman numerals never repeat a symbol four times, so IV (one before five) is used. IIII does appear on many clock faces, which is a design tradition rather than a different rule.

What is the largest number in standard Roman numerals?

3999, written MMMCMXCIX. Beyond that you need a vinculum, a bar over a symbol that multiplies it by a thousand.
