Which letters are counted as vowels?

The tool counts a, e, i, o, and u in both upper and lower case. The letter y is treated as a consonant.

Does punctuation or whitespace affect the count?

No. Only the 26 English letters are classified. Spaces, digits, and punctuation are tallied separately under "Other characters" and do not influence the vowel or consonant counts.

Is my text stored or sent anywhere?

All analysis runs entirely in your browser using JavaScript. No data is transmitted to any server.

How is the vowel-to-consonant ratio calculated?

The ratio divides total vowels by total consonants, rounded to two decimal places. If there are no consonants it shows the vowel count followed by ":0".

What is a typical vowel percentage for English text?

Standard English prose averages around 38–42% vowels among all letters. Values well above or below that range can indicate unusual content, heavy use of acronyms, or non-English text.

How do I count vowels in Python?

Use a generator expression with the built-in sum function: sum(1 for ch in text.lower() if ch in "aeiou"). This iterates each character, lower-cases it, and counts the ones in the vowel set. This tool gives the same result without writing code.
