Random Letter Generator

About this tool

Random Letter Generator draws a single random letter from the English alphabet each time you click. Press Draw letter and a large uppercase letter from A to Z appears, chosen with the browser's Web Crypto API so every letter in the pool is equally likely. Tick Exclude vowels to draw only from the 21 consonants. It is a fast, no-setup tool for word games, category games, literacy activities, creative writing prompts, and any situation where you need a random starting letter. Need several letters? Click again for each one — every draw is independent, so letters can repeat. Everything runs locally in the browser — no server calls, no account, and no tracking.

Why use it

• Perfect for Word and Category Games: Get the random starting letter needed for Scattergories-style rounds, word-building challenges, or custom classroom games without paper slips or tiles.

• One Big, Readable Letter: The result is shown in large type, easy to see from across a room or on a shared screen.

• Consonant-Only Option: Exclude vowels to draw from the 21 consonants — handy for phonics exercises or games where a vowel start is too easy.

• Creative Writing Prompt Starter: Draw a letter and challenge yourself or your students to write a sentence, poem or story built around words starting with it.

• Unbiased Draws: Letters are chosen with the Web Crypto API, avoiding the patterns people fall into when they pick a 'random' letter themselves.

• Instant and Private: No setup, no account, and nothing is sent to a server.

How to use

1. Optionally tick Exclude vowels (A, E, I, O, U) to draw only from the 21 consonants.
2. Click Draw letter.
3. Read the uppercase letter shown in large type below the button.
4. Click Draw letter again for another independent letter — repeats are possible.

When it helps

• When playing a category or word game that needs a random starting letter for each round
• When creating a classroom phonics exercise that needs random letters, or consonants only, for students to sound out
• When a creative writing group needs a random letter prompt to kick off an alphabet challenge
• When playing a word association or improv game that assigns a random starting letter to each participant
• When you need a random single-character code or prefix for naming things

Examples

Tips

• For a category game, draw a new letter at the start of each round and share your screen so every player sees the same letter.
• Tick Exclude vowels to avoid easy vowel starts and make word games harder.
• To build an acrostic prompt, click Draw letter five to eight times and write down each result in order — repeats are part of the challenge.
• If a hard letter like Q, X or Z comes up and your group agrees it is unplayable, simply draw again.
• Draw a single random letter each morning as a creative constraint: brainstorm every word you know beginning with it, or sketch only objects that start with it.

Frequently Asked Questions

Glossary

Sampling with Replacement

A random sampling method where each selected item is returned to the pool before the next draw, allowing the same value to appear multiple times. Every click of the letter generator is a draw with replacement.

Uniform Distribution

A probability distribution where every outcome in the active set has equal likelihood. The letter generator applies a uniform distribution across all letters in the current pool.

Vowel

The letters A, E, I, O, and U in the English alphabet, representing open vocal tract sounds. The generator's Exclude vowels option removes these 5 letters, leaving a pool of 21 consonants.

Consonant

Any letter other than a vowel — the 21 non-vowel letters of the English alphabet, including Y in this tool.

Acrostic

A poem or text where the first letter of each line, word, or other unit spells out a word, message, or in this context, a random letter sequence used as a creative writing constraint.
