Pick random letters instantly — filter by case, vowels or consonants, and see the NATO phonetic alphabet. One click, no sign-up.
Every word generator you need, all free
Numbers, names, games and more
A random letter generator picks letters from the alphabet at random. That sounds simple, but the details matter: you can control how many letters you get, whether they come out uppercase, lowercase, or mixed, and whether the pool is limited to vowels, consonants, or the full A–Z set. Toggle on frequency weighting and the results reflect real English distribution — E and T appear far more often than Q or Z, just as they do in actual writing. Every letter appears instantly; there's no loading, no account, nothing to install.
The single biggest use case for a letter generator is word games. In Scrabble, dealing yourself a random rack of seven letters is the fastest way to practice anagram-solving without needing a physical board. Set count to 7, turn off duplicates, and hit generate — you have a practice rack in one click. For Boggle, generate 16 letters to simulate a 4×4 grid. Wordle players use five random letters as a constraint for practice rounds: can you build a valid five-letter word from what you got?
The consonants-only and vowels-only filters are especially useful here. If your rack is vowel-heavy, practice exclusively with vowels to sharpen your ability to spot words like AUDIO or OUIJA. If you want to drill consonant clusters, flip to consonants only.
The vowels-only and consonants-only filter is something no other letter generator offers, and it matters for teaching. Sorting the alphabet into vowel and consonant groups is one of the earliest phonics milestones — children need to understand that every syllable needs a vowel before they can reliably decode words they have never seen before. Use vowels-only mode to focus a drill entirely on A, E, I, O, U. Use consonants-only to practise the remaining 21 letters separately.
Turn on Show letter number to drill alphabetical order — seeing "(5)" under E and "(26)" under Z builds the mental number-line children need for dictionary use and alphabetisation. Generate one letter at a time for flash-card style practice, or generate ten for a sorting exercise.
ESL and EFL teachers can generate random letters for warm-up activities: students name an animal, country, or food beginning with each letter they see. It takes thirty seconds to set up and keeps a class moving.
Toggle on Show NATO phonetic and every letter card shows its NATO word: Alpha for A, Bravo for B, Charlie for C, all the way to Zulu for Z. The NATO phonetic alphabet was developed specifically to prevent miscommunication when spelling words over radio, telephone, or in noisy environments. Letters like B and D, M and N, or P and T sound nearly identical over a poor connection — but "Bravo" and "Delta" are impossible to confuse.
It is used daily by commercial and military pilots communicating with air traffic control, emergency services dispatchers, call centre agents confirming booking references, and anyone spelling a name or address over a call. Practising with this tool — generating random letters and reciting the NATO word for each — builds the automatic recall you need to use it fluently under pressure.
Not all letters are created equal. E accounts for roughly 12.7% of letters in typical English text; T follows at 9.1%, then A at 8.2%, O at 7.5%, and I at 7.0%. At the other end of the scale, Z appears in just 0.07% of text, Q in 0.10%, and X in 0.15%. This huge gap — E is nearly 180 times more common than Z — shapes everything from Scrabble tile scoring to cryptography and keyboard layout design.
Turn on the "Weight by English frequency" toggle to see this in action. Instead of every letter having an equal chance, the generator weights picks by these real-world frequencies. Writers use it to generate letter constraints that feel natural rather than artificially exotic. Wordle players use it to practise guessing high-frequency letters first.
Generate three random letters and write a sentence where each word starts with one of them — in order. It sounds like a simple constraint, but the limitation forces unexpected word choices and lateral thinking. Try it: if your three letters are R, T, and W, you might write "Rabbits travel well." or "Rain transforms winters." The randomness prevents you from defaulting to your usual vocabulary. For more developed prompts — full words to build sentences around — the random word generator pairs naturally with this tool.
