Letter Frequency Counter

Count how many times each letter appears in your text. Every letter gets its count and share, sorted by most used or A to Z, next to how often it appears in ordinary English.

Frequency analysis for ciphers and puzzles

Letter frequency is how a substitution cipher is broken. Paste the coded text, sort by Most used, and compare the top letters with English: the most common letter in the code probably stands for e, the next ones for t, a and o. In a Caesar cipher every letter is shifted by the same amount, so finding e is often enough to read the whole message.

The same counts help with word games and writing. A–Z shows whether a sentence is a pangram that uses all 26 letters, or a lipogram that avoids one, and the vowel and consonant totals show how a name or a headline is built.

Frequently asked questions

What counts as a letter?

Letters of any alphabet: æ, ø, å, é and ü count just like a to z, and so do Greek, Cyrillic and other scripts. Digits, spaces and punctuation are left out of the letter total, which is why it is lower than the character count.

Which letters count as vowels?

a, e, i, o and u, with or without an accent, plus æ, ø, å and œ. Y is counted as a consonant, because whether it behaves as a vowel depends entirely on the word it is in. Letters from other alphabets are counted as letters but as neither vowels nor consonants, and are shown on a line of their own.

Does it count upper and lower case separately?

No. A and a are counted as the same letter, so the frequency reflects the words rather than the styling.

What is letter frequency actually useful for?

Word games and crosswords, cryptograms and simple ciphers, and checking how a name, headline or slogan is built. In ordinary English text, e, t and a are usually the three most common letters.

What does EN mean in the results?

It is how often that letter appears in ordinary English text, so you can see at a glance which letters your text uses more or less than usual. In the chart it is the thin line: a bar that ends past the line means your text uses that letter more than usual. It appears once the text has 100 letters, because a shorter text is too small to compare. With Vowels or Consonants selected, it is the share within that group. In a substitution cipher, the most common letter in the coded text is most likely e, then t and a. Choose A–Z to see every letter, including the ones the text never uses.

Why is the total letters number lower than the character count?

Total letters counts letters and nothing else. The character count under the result counts everything you pasted, spaces and punctuation included.

How is this different from the Character Counter?

The Word & Character Counter answers how long the text is, in characters, words, sentences and paragraphs. This one answers what the text is made of, letter by letter.
