Random Letter Generator
Generate one random letter or a whole string of them. Pick uppercase or lowercase, restrict to vowels or consonants, and rule out repeats.
A random letter generator picks letters from the alphabet with no pattern, which is what you need for word games, name prompts, classroom drills and test data. Each letter has an equal chance of appearing, so with repeats allowed the same letter can come up twice in a row - that is randomness working, not a fault.

Frequently asked questions
How do I generate a single random letter?
Set the count to one and generate. Each of the 26 letters has the same chance of appearing, roughly 3.85% each.
Why did the same letter appear twice?
Because true randomness has no memory. With repeats allowed, two identical letters in a row is expected about once every 26 draws. Switch off repeats if you need all of them different.
How many letters can I generate without repeats?
Twenty-six, one for each letter. Restricted to vowels the ceiling is five, and to consonants it is twenty-one.
Is this good enough for a password?
No. Use a password generator instead - it mixes cases, digits and symbols and uses your browser's cryptographic random source. Letters alone are far too weak.
How is the randomness generated?
In your browser, from JavaScript's built-in random number source. Nothing is sent anywhere and no result is stored or logged.
Can I use this for Scattergories or Scrabble?
Yes, that is the common use. For Scattergories most house rules drop the awkward letters - switch to consonants and re-roll if you land on Q, X or Z.
What about a random letter for each student?
Set the count to the size of the class and turn repeats off, so every student gets a different letter. Above 26 you will need repeats back on.
