Random Letter Generator
The Random Letter Generator picks one or more random letters in a single click — all 26 letters, vowels only, or consonants only, in upper or lower case, with repeats allowed or switched off. It is free, works instantly in your browser, and is perfect for classroom games, spelling practice, word games, and quick draws.
How it works
Start by choosing how many letters you want, from 1 to 100. Then pick the letter set: all 26 letters, the 5 vowels (A, E, I, O, U), or the 21 consonants. The case setting controls how the result looks — all capitals, all lower case, or a mix where each letter is randomly upper or lower case. Finally, decide about repeats: with repeats allowed, the same letter can turn up twice in one result; with repeats off, every letter is different, so the count cannot be larger than the pool you chose.
Press Generate and the tool draws your letters using your browser's random number generator, which gives every letter in the set an equal chance. The result updates on every click, and changing any setting generates a fresh set straight away, so you can flip between vowels and consonants without pressing the button again. Copy puts the letters on your clipboard, and Download saves them as a plain text file you can open anywhere.
If you turn repeats off and ask for more letters than the pool holds, the tool does not fail silently — it tells you the limit and suggests the largest count that works. For example, vowels only with no repeats tops out at 5 letters, and consonants only with no repeats tops out at 21. With repeats allowed there is no such limit, so you can ask for all 100 letters from any set.
Worked example
Suppose a teacher wants five random uppercase letters, repeats allowed, to start a spelling game. Set the count to 5, the letter set to "All letters", the case to "UPPERCASE", and repeats to "Allow repeats", then press Generate.
Step 1: The tool draws five times from the 26 letters, and each draw has a 1 in 26 chance of landing on any given letter.
Step 2: One run of the tool gave the letters Q, W, K, M, and Z — in that order.
Step 3: Because repeats were allowed, a letter could have appeared twice; in this run none did, which is normal for only five draws.
Step 4: The result reads Q W K M Z, and the teacher can copy it or press Generate again for a fresh set.
The tool shows exactly this kind of result: five random uppercase letters with a note that each letter had a 1 in 26 chance. Your own run will give different letters — that is the point — but the count, case, and settings will match what you chose. Try the same settings above and press Generate to see your own five letters.
FAQ
How do I generate a random letter?
Set the count to 1, pick the letter set and case you want, and press Generate. The tool shows one random letter instantly. Press Generate again for a new letter, or raise the count to get a whole string of random letters at once.
Can I generate only vowels or only consonants?
Yes. Choose Vowels only to draw from A, E, I, O, and U, or Consonants only to draw from the other 21 letters. That is useful for phonics practice, spelling games, and word games where you need a particular kind of letter.
What does allow repeats do?
When repeats are allowed, the same letter can appear more than once, so a set of five letters might contain two Es. When repeats are off, every letter in the result is different, which means the count cannot be larger than the letters available — 26 for all letters, 5 for vowels, and 21 for consonants.
Are the letters truly random?
The letters are picked with your browser's built-in random number generator, which gives an even spread across the letters you chose. Every letter in the set has the same chance on each draw, and no pattern or seed is reused between clicks.
What can I use random letters for?
Random letters are handy for classroom games, spelling practice, word games like Scrabble and Boggle, picking a starting letter for a story or a name, raffles, and quick team draws. Teachers often use one random letter as the starting letter for a brainstorming round.
