Roman numerals worksheet generator

Convert numbers to Roman numerals, numerals to numbers, or both on one sheet. Choose the range — 1–20 for clock faces and chapter headings, 1–100 once L and C are needed, or 1–1000 for the four-symbol numerals like MCM. Download an A4 or US Letter PDF with the answer key.

Choose the direction and the range, preview the sheet, then download the PDF — no account needed.

Quick presets

The range decides which symbols a child needs. 1–1000 is where the four-symbol numerals appear: 900 is CM, so 1900 would be MCM.

  2. Pick the range — 1–20, 1–100 or 1–1000 — and how many questions.
  3. Download the PDF, print it, or copy a share link that restores these settings.

Using these worksheets in teaching

Roman numerals are not on the critical path of anything, and that is precisely what makes them useful: they are a second number system a child can hold up against their own. The comparison is the lesson. Ask why 1998 takes so many symbols in one system and four digits in the other, and place value stops being the invisible thing it usually is. Teach writing greedily — take the largest symbol that fits, subtract, repeat — and reading additively with the one exception that a smaller symbol before a larger one is subtracted; those two rules cover everything on this sheet. The predictable stumbles are 4 and 9 at every scale (IV, IX, XL, XC, CD, CM), so a sheet in the 1–100 range that a child sails through is worth reissuing at 1–1000, where the same pattern reappears one order of magnitude up and catches anybody who memorised rather than understood.

Frequently asked questions

What do the three ranges change?
Which symbols a child has to know. 1–20 uses I, V and X only, which is the clock face and the chapter heading. 1–100 brings in L and C. 1–1000 brings in D and M and, with them, the numerals that need four symbols — 900 is written CM, so 1900 is MCM. Each range is a genuine step rather than a bigger version of the last.
Are subtractive numerals used?
Yes, in the standard modern form: 4 is IV rather than IIII, 9 is IX, 40 is XL, 90 is XC, 400 is CD and 900 is CM. Every numeral on the sheet is the one canonical spelling of its number, so an answer key is never arguable. The clock-face convention of IIII for four is a watchmakers’ tradition rather than a rule, and does not appear here.
What does the mixed direction do?
It draws from both conversions on the same sheet, so a child cannot settle into one. Reading a numeral and writing one are genuinely different tasks: reading is addition with a rule about smaller-before-larger, and writing means choosing symbols greedily from the largest down. A sheet that only does one of them leaves the other untested.
Why does it stop at 1000?
Because 1000 is exactly "M", which makes the ceiling a clean one. The notation has no standard way of writing numbers above 3999 at all — the overline that multiplies by a thousand is not something a child needs — so the range stops well short of the awkward end rather than approaching it.
Is there a zero?
There is no Roman numeral for zero, which is why every range starts at 1. It is worth saying out loud: the absence is a real fact about the notation and the reason arithmetic in it is so painful.
Which paper sizes are supported?
A4 and US Letter, laid out for each rather than scaled: the number of columns and rows is computed from the paper you choose.
