How to use this table
The table above lists every number from 1 to 100 with the numeral you should write and, where one exists, the spelling people write instead. Symbols go largest first and add up, and a smaller symbol placed before a larger one subtracts. Almost every error in this range comes from ignoring that second rule and simply repeating a letter until the total is reached.
The range 1 to 100 covers the whole set of everyday numerals, from I up to C (100). It contains all six subtractive pairs you need at this scale: IV (4), IX (9), XL (40), XC (90), plus the single letters L (50) and C (100). Master these and you can read any number below a thousand.
Frequently asked questions
How do you write the numbers 1 to 100 in Roman numerals?
They run from I (1) to C (100). For each one, take the largest Roman value that still fits, write its symbol, subtract it and repeat. The table above shows the finished numeral for every value, and each number links to its own step-by-step guide.
Which numbers between 1 and 100 are most often written wrongly?
98 of them have a well-known wrong form, and the table lists it next to the correct numeral. They are the values where a symbol would otherwise need a fourth repeat, so a subtractive pair takes over instead: 4 becomes IV rather than IIII and 9 becomes IX rather than VIIII, with the same thing happening at 40 (XL, not XXXX) and 90 (XC, not LXXXX).
How do you check a numeral in this range is right?
Read it back and add the groups up. If the total returns to the number you started from, the spelling is standard. The converter on this site round-trips every value and rejects non-standard forms, so anything it accepts is safe to use.
