Roman numerals 1 to 1000

From I to M in one chart

One to one thousand is the complete lower system, from a single stroke to M, the largest single Roman symbol. It adds the hundreds to everything the 1 to 100 chart already covers: C, then CC and CCC, the subtractive CD at four hundred, D for five hundred, DC through DCCC, the subtractive CM at nine hundred, and finally M. A three-figure numeral simply stacks a hundreds group, a tens group and a units group, read from the largest down.

Four hundred (CD) and nine hundred (CM) are the hundreds-place mirrors of forty and ninety. If you can read XL and XC, you already understand CD and CM: the same subtractive shape, one place value up. That symmetry is the reason the system scales so neatly.

Reading a three-part numeral

Take a value like 847. Break it into eight hundred (DCCC), forty (XL) and seven (VII), and you get DCCCXLVII. Every number in the hundreds works this way: find the hundreds, then the tens, then the units, write each group, and set them side by side. The chart lets you trace that pattern across a thousand rows, which is the fastest way to get comfortable with longer numerals.

This is also the range where numerals start to get long. Numbers built from repeated hundreds and tens, like 888 (DCCCLXXXVIII), stretch out because Roman numerals are additive and never compress the way Arabic digits do. That length is worth seeing before you engrave or tattoo one.

The full lookup, plus single pages

This chart is the master lookup for any value up to a thousand. Every row links to a full page for that number, with a breakdown of how the numeral is built and where it is used, so you can go from the table to the detail in one tap. Print the chart for a complete paper reference, or use the converter above for a value you just want to check quickly.
