Random Letter Generator

Need a random letter for a word game, a classroom activity, a password hint or picking a category in Scattergories-style games? This generator draws letters from the English alphabet, vowels or consonants only, the Greek or Russian Cyrillic alphabet, Korean Hangul consonants or vowels, or any set you type yourself. Draw one letter or a thousand, with or without repeats, in upper, lower or mixed case.

How to use this tool

1. Choose the letters to draw from, or type your own set.
2. Set how many letters you want and whether letters may repeat.
3. Optionally choose the case, letters to leave out and the separator.
4. Press the button and copy the letters; the sorted list and the tally help with checking.

Formula

P(letter) = 1 ÷ number of letters in the set (each draw)

Each letter is picked with an unbiased secure random integer, so with 26 letters every letter has exactly a 1 in 26 chance (3.85%) on every draw. Without repeats, the page draws a random sample instead, so no letter can come up twice. Excluded letters are removed from the set before drawing.

Example

Drawing 5 letters from A–Z with repeats allowed gives each letter a 3.85% chance per draw, and there is a 1 − (26 × 25 × 24 × 23 × 22) ÷ 26⁵ ≈ 33.6% chance that at least one letter repeats. Drawing all 5 vowels without repeats always returns A, E, I, O and U in a random order.
