Random letter generator

Draw random letters from A to Z, from the whole alphabet or just the vowels or consonants.

Your letter

How the draw works

Every click asks your browser's cryptographic random number generator (the same machinery used to create encryption keys) for fresh, unpredictable values, then maps them onto your chosen set of letters using rejection sampling. That avoids the subtle bias of naive methods, so each of the 26 letters has an exactly equal chance, and A is no more likely to appear first than Q. The draw happens entirely on your device: nothing is uploaded, and nobody can see or influence the result.

Switch the set to vowels and the pool shrinks to A, E, I, O and U, each with a 1 in 5 chance. Switch to consonants and you draw from the other 21 letters, each at 1 in 21. Y is counted as a consonant, which is how most word games treat it.

Equal chances, unlike real English

chance of any single letter = 1 ÷ 26 ≈ 3.8%

Written English is heavily lopsided: E is the most common letter by a distance, while Z, Q and X are rare. This tool ignores all of that and gives every letter the same weight, which is exactly what you want for a fair game. Nobody can complain that the generator favours easy letters.

What is the chance a random letter is a vowel?
5 of the 26 letters are vowels, so 5 ÷ 26 = about 19.2%, roughly one draw in five.
What is the chance two draws give the same letter?
Whatever the first letter is, the second matches it with probability 1 ÷ 26, about 3.8%. Repeats are uncommon but entirely normal.
How many three-letter sequences are possible?
26 × 26 × 26 = 17,576 ordered sequences. Ask for three letters and every one of those outcomes is equally likely, whether it spells CAT or XQZ.

Games and other uses

  • Name, place, animal, thing: generate one letter per round and everyone races to fill their categories. The equal odds mean dreaded letters like X turn up as often as friendly ones.
  • Scattergories-style party games: a neutral letter picker stops arguments about whose turn it was to choose.
  • Phonics and spelling practice: draw a letter and ask a child for its sound, a word that starts with it or a word that ends with it. The vowels setting is handy for early readers.
  • Creative prompts: give yourself a letter and write a sentence, character name or story title starting with it.
  • Fair ordering: pick a letter and start with whoever's surname is closest to it, a quick way to choose who presents first.

Batches, repeats and fairness

Ask for more than one letter and each position is drawn independently, like rolling a 26-sided die again and again. That means repeats can and do appear: in a batch of ten letters there is roughly an 86% chance at least two match. If your game needs every letter to be different, the simplest approach is to draw one at a time and re-draw whenever you hit a letter you have already used.

Because every draw is independent, past results tell you nothing about future ones. Ten consonants in a row does not make a vowel overdue: the next draw from the full alphabet is still 21 to 5 in favour of a consonant, exactly as it always was.

Frequently asked questions

Is every letter equally likely?

Yes. Each draw uses your browser's cryptographic random number generator with rejection sampling, so all 26 letters have an identical 1 in 26 chance. That is quite unlike written English, where E appears far more often than Z.

Can the same letter come up twice?

Yes. Each draw is independent, like rolling a 26-sided die, so a batch of ten letters can easily contain repeats. If you need every letter to be different, draw them one at a time and skip any you have already had.

Which letters count as vowels?

A, E, I, O and U. The consonants set holds the other 21 letters. Y sometimes acts as a vowel in English words, but for this tool it is treated as a consonant, which matches how most word games handle it.

Why are the letters in capitals?

Capitals are easier to read at a glance and avoid confusion between lookalikes such as lower case l and capital I. The draw itself is identical either way, since case does not change which letter was picked.

What is a random letter useful for?

Party and classroom games such as name, place, animal, thing, picking who goes first by initial, phonics practice with children, creative writing prompts and quiz rounds. Anywhere you need a letter nobody chose on purpose.
