Free Letter Frequency Counter
A letter frequency analysis breaks down how often each letter appears in your text. In English, E is the most common (~12.7%), followed by T, A, O, I, and N. The counter below ranks every letter in your text with counts and percentages.
How the Letter Frequency Counter Works
The counter scans your text, normalizes case, keeps only alphabetic characters, and tallies each letter. The result is a ranked list of all 26 letters with their counts and percentage of the total letter pool.
Tips & Best Practices
1ETAOIN SHRDLU is the English letter order
The 12 most-frequent letters in English are E, T, A, O, I, N, S, H, R, D, L, U. Any unusual order in your text could signal foreign-language influence or technical content.
2Useful for cryptography
Frequency analysis is the foundation of classical cryptography. Substitution ciphers can often be broken by matching letter frequencies to standard English.
3Wheel of Fortune strategy
The most common consonants (T, N, S, R, L) and vowels (E, A, I, O) are the best first guesses in any English word puzzle.
4Helps validate translations
Translated text should roughly match the target language's letter frequency. A wildly off-distribution may signal stilted translation.
