Vowel and Consonant Counter

Vowel, consonant and letter totals for a passage of text, Turkish letters included.

How it is calculated

The text is lower-cased and every Latin-script letter is examined; spaces, digits, punctuation and symbols are skipped. A letter counts as a vowel if it is a e i o u, the Turkish ı ö ü, or an accented or ligature vowel such as â î û é è ë ï ó ä å æ œ ø. Every other Latin letter is a consonant, including y, ñ, ç, ş, ğ and ß-type letters. letters = vowels + consonants. Turkish capitals are handled correctly: I is read as ı and İ as i. Letters from other scripts, such as Cyrillic or Greek, are ignored entirely: they are neither vowels nor consonants and are not in the letters total. A blank box returns nothing, while text with no Latin letters gives 0, 0 and 0.

Worked example

Enter “Işık İstanbul”. The tool ignores the space and reads I as ı and İ as i. The letters of the first word are ı, ş, ı, k, which is 2 vowels and 2 consonants. The second word gives i, s, t, a, n, b, u, l, which is 3 vowels (i, a, u) and 5 consonants. Adding both words gives 5 vowels and 7 consonants. The tool reports 5 vowels, 7 consonants and 12 letters in total.

Common mistakes

  • Counting y as a vowel. In “rhythm myth” the tool finds 0 vowels and 10 consonants, because y is always treated as a consonant.
  • Pasting text in Cyrillic, Greek or another non-Latin script and expecting counts. Those letters are skipped entirely, so “Привет” gives 0, 0 and 0.
  • Expecting digits, spaces or punctuation to be counted as consonants. They are ignored, so the letters total is not the same as the character count.
  • Treating the result as a phonetic count. The tool sorts letters, not sounds, so a silent e still counts as a vowel and a letter like w or ñ still counts as a consonant.
  • Assuming a vowel-to-consonant ratio is shown. Only the three counts are given, so divide them yourself if you need a ratio.

About this calculator

This tool scans a block of text character by character, sorting each letter into vowels (a, e, i, o, u, plus accented and Turkish vowels such as ı, ö, ü; y counts as a consonant) or consonants, while ignoring spaces, digits, and punctuation, then reports the number of vowels, consonants and letters.

Students and teachers use it for phonics exercises and spelling drills, writers and editors use it to check the rhythm and readability of a passage (heavily consonant-clustered text tends to read as denser or harsher), and programmers use it as a quick sanity check when testing string-processing or text-analysis code.
