Random Letter Generator
Generate one or more random letters from the alphabet. Choose uppercase, lowercase, or mixed. Free, instant.
How to use this tool
- Choose how many letters to generate.
- Select uppercase, lowercase, or mixed case.
- Toggle unique mode to prevent repeating the same letter.
- Click Calculate to draw; click again to redraw.
Draw one or more random letters from the English alphabet. Useful for word games, Scrabble practice, random variable naming, and educational exercises.
How it works
The Random Letter Generator selects one or more letters from the English alphabet at random. You can choose uppercase only, lowercase only, or mixed case. When Unique only is enabled, no letter appears twice in the same output, which is useful when you need a set of distinct letters rather than a sequence that may repeat.
Common uses include word games like Scrabble or Boggle practice, classroom activities where students form words from a random set, generating placeholder labels for variables or nodes in diagrams, and creating random quiz prompts.
For Scrabble-style practice, generate 7 unique letters (mixed case off, unique on) and challenge yourself to form the longest word possible. For random variable naming in whiteboard sessions, generate a few uppercase letters as stand-in names for unknowns.
Worked example
Generating Scrabble practice tiles
- Set Number of letters to 7.
- Set Case to Uppercase.
- Enable Unique only.
- Click Generate.
- Try to form the longest valid word from the seven letters.
Seven unique uppercase letters, e.g. A, T, R, E, N, S, O, ready for a word challenge.
Common mistakes to avoid
- Requesting unique letters with a count above 26, which is impossible with the English alphabet.
- Forgetting to enable Unique only for word games, resulting in repeated letters that may not match the game's tile distribution.
- Using mixed case output when the downstream use (e.g. a word game) requires a consistent single case.
Key terms
- Unique only
- A mode where each letter in the output appears at most once, preventing repetition.
- Mixed case
- Output that includes both uppercase and lowercase letters chosen randomly.
- Alphabet sample
- A randomly selected subset of letters from the 26-letter English alphabet.
Frequently asked questions
- What does 'unique' mean here?
- With unique enabled no letter appears twice in a single draw — like drawing tiles without replacement.
- Can I generate the full alphabet randomly?
- Set count to 26 and unique to Yes for a random shuffle of the full alphabet.
