Who Uses Letter Frequency Analysis?

🔐

Cryptographers

Letter frequency is the primary method for breaking substitution ciphers. E is almost always the most frequent letter.

🎲

Scrabble Players

Knowing that E, A, R, I, O, T, N, S are most common helps you evaluate rack balance and predict what tiles remain.

🧑‍💻

Developers

Used in data compression, keyboard layout design (QWERTY vs Dvorak), and natural language processing algorithms.

📚

Linguists

Compare letter distributions across authors, genres, or time periods to identify writing styles and patterns.

🎓

Students

Perfect for analyzing literature, understanding phonetics, or studying language patterns in class assignments.

🧩

Puzzle Solvers

Analyze cryptograms and coded messages by identifying the most frequent symbols and matching to common letters.

Frequently Asked Questions

Letter frequency refers to how often each letter of the alphabet appears in a given text or language. In English, E appears most often (~13%), while Z appears least often (~0.07%). This information is used in cryptography, linguistics, game design, and more.

Paste your encrypted text into the analyzer. The most frequent symbol in your cipher likely maps to E, the second most common to T, then A, O, I, N, S, H, R in roughly that order. Use "Compare to English" mode to see how your text's distribution matches standard English frequency.

In order: E, T, A, O, I, N, S, H, R, D, L, C, U, M, W, F, G, Y, P, B, V, K, J, X, Q, Z. The phrase "ETAOIN SHRDLU" was famously used by old-school typographers as a mnemonic for the 12 most common letters.
