Roman Numerals 1 to 100: the Complete Chart

This chart lists the Roman numerals from 1 to 100, from I all the way to C, plus a handful of larger values you will actually look up: 500 (D), 1000 (M) and recent years like 2024 (MMXXIV) and 2026 (MMXXVI). Each numeral has its own copy button, and you can filter or sort the table with a click.

The whole range from 1 to 100 relies on just five letters. I is 1, V is 5, X is 10, L is 50 and C is 100. Reading a numeral is mostly addition: XVII is 10 plus 5 plus 2, so 17. The twist comes from six subtractive pairs, where a smaller letter placed before a larger one is subtracted instead of added. Between 1 and 100 you will meet four of them: IV (4), IX (9), XL (40) and XC (90). That is why 49 is written XLIX rather than IL, and why 99 is XCIX rather than IC: the subtraction rules only allow I before V or X, and X before L or C.

Some rows are worth flagging because people get them wrong all the time. 44 is XLIV, four letters covering two subtractions. 88 is the longest numeral in the chart, LXXXVIII, eight letters for a two-digit number. And 40 is XL, never XXXX: no letter may repeat more than three times in a row.

The chart also answers the classic clock question. Many watch faces show 4 as IIII instead of IV, a deliberate tradition that survives on dials from Cartier to Big Ben's little sisters. It is fine on a clock, and wrong everywhere else.

Need a value that is not in the table, like 1987 or 3999? The Roman numeral converter handles any number from 1 to 3999 in both directions and shows how each numeral breaks down symbol by symbol.
