Roman Letter Chart

Roman numerals use just seven letters — I, V, X, L, C, D and M — combined by a few simple rules. This chart shows every number from 1 to 100 and the hundreds up to 1,000, colour-codes the building blocks, and lets you build any number from 1 to 3,999 step by step. A quick quiz helps the patterns stick.

The seven Roman numeral letters

LetterValueMemory hint
I1One finger
V5An open hand (thumb and finger make a V)
X10Two Vs, one upside down
L50
C100Latin centum — as in century
D500
M1,000Latin mille — as in millennium

A popular memory sentence for the order is “I Value Xylophones Like Cows Do Milk”.

The rules

  1. Write letters from largest to smallest and add them: XVI = 10 + 5 + 1 = 16.
  2. Don’t repeat a letter more than three times in a row: 3 is III, but 4 is not IIII (except on some clock faces).
  3. A smaller letter before a larger one is subtracted — but only in six pairs: IV (4), IX (9), XL (40), XC (90), CD (400), CM (900).
  4. V, L and D are never repeated and never subtracted.
  5. Write each place value separately: 49 is XLIX (40 + 9), not IL.

Learn these two columns and the ones (I to IX) and you can write any number up to 3,999 by joining the pieces: 1,987 = M + CM + LXXX + VII = MCMLXXXVII.

Worked example

To write 444: 400 is CD, 40 is XL and 4 is IV, so 444 = CDXLIV. To read MCMXCIX, split it into place values: M (1,000) + CM (900) + XC (90) + IX (9) = 1,999. The builder above shows this breakdown for any number, colour-coding each letter.

Common mistakes

WrongRightRule
IIII (4)IVNo letter four times in a row (clocks are the exception)
VV (10)XV, L and D are never repeated
IC (99)XCIXI can only be subtracted from V and X
IL (49)XLIXSubtract only one step: I from V/X, X from L/C, C from D/M
VX (5)VV is never subtracted
MCMC (2000)MMWrite place values separately

Reading long numerals quickly

  1. Scan from left to right.
  2. Whenever a letter is smaller than the one after it, treat the pair as one subtraction (CM = 900).
  3. Group the letters into thousands, hundreds, tens and ones.
  4. Add the groups: MMXXIV = 2,000 + 20 + 4 = 2,024.

With practice, you’ll recognise common chunks — CM, XC, IX — at a glance, which makes film credits and building dates easy to read.

Teaching Roman numerals

A little history

Roman numerals developed from tally marks used in ancient Italy and were the standard way to write numbers across the Roman Empire and in Europe for more than a thousand years. They were gradually replaced by Hindu–Arabic numerals (0–9) from the late Middle Ages, because place value and zero make arithmetic far easier. Romans themselves were not always consistent: IIII and VIIII appear in ancient inscriptions alongside IV and IX.

Where you still see Roman numerals

Lowercase Roman numerals

Lowercase numerals (i, ii, iii, iv…) are common for page numbers in book front matter and for sub-points in outlines and legal documents. They follow exactly the same rules as capitals.
