Ordinal Number Generator
Used by developers, writers, and creators worldwide.
An ordinal number generator converts a plain number into its ordinal form — the version that shows position or rank, such as 1st, 2nd, 3rd, and 21st. Ordinals follow a small set of rules that catch people out: most numbers take "th", but those ending in one, two, or three usually take "st", "nd", or "rd", except for the teens, where eleven, twelve, and thirteen all take "th". Enter any number and the tool applies these rules correctly, returns the ordinal numeral, gives an example sentence, and spells out the word form for smaller values. Writers use it to format dates and rankings, developers to generate correct labels in lists and leaderboards, and teachers to demonstrate the pattern. Everything is computed instantly in your browser, so even tricky cases like 111th and 1,002nd come out right. Use it whenever you need the ordinal of a number without second-guessing the suffix.

FAQ
what are the ordinal suffix rules
Most numbers take "th". Numbers ending in 1 take "st", in 2 take "nd", and in 3 take "rd" — so 1st, 2nd, 3rd. The exception is the teens: 11th, 12th, and 13th all take "th" despite their final digit, and the pattern repeats every hundred.
why do 11, 12, and 13 use th
The teens are a special case in English. Although 1, 2, and 3 normally take st, nd, and rd, the numbers 11, 12, and 13 take th — we say eleventh, twelfth, and thirteenth. The tool handles this so 111th and 213th come out correctly.
does it spell out the word form
For numbers up to twenty it also gives the written word, such as "fifth" or "twentieth". Larger numbers return the ordinal numeral and an example sentence, since spelling out big ordinals in full is rarely needed.
