Character Frequency Counter

Character Frequency Counter

Use this free Character Frequency Counter to find how often each letter appears in your text. Paste or type your text into the box above, and the tool instantly calculates the frequency of every letter it finds.

The counter is case-insensitive, so uppercase and lowercase versions of the same letter are counted together. For example, A and a are treated as the same letter. Spaces, punctuation, and numbers are ignored when calculating letter frequencies.

How to Count Character Frequency

To analyze the frequency of letters in your text:

1. Type or paste your text into the input box.
2. The Character Frequency Counter analyzes the text automatically.
3. View each letter and the number of times it appears.
4. Check the total number of letters and the number of distinct letters.
5. Copy or download the result if you need it elsewhere.

There is no need to count letters manually, even when working with a large block of text.

What Does the Character Frequency Counter Count?

This tool focuses specifically on alphabetic letters. It shows each letter found in your text together with its frequency.

For example, if your text contains:

Apple apple APPLE

the uppercase and lowercase letters are combined when counting frequency.

The tool does not include spaces, punctuation marks, or numbers in the letter-frequency results.

Letter Frequency Counter

A letter frequency counter measures how many times each individual letter occurs in a piece of text. This can help you quickly identify the most common and least common letters without checking the text manually.

The results are sorted by frequency, making repeated letters easy to identify. The tool also displays the total number of letters counted and the number of distinct letters found.

Case-Insensitive Letter Counting

The counter is case-insensitive. This means A and a, B and b, and other uppercase and lowercase forms are grouped together.

For example:

AaBbA

is counted as:

a: 3
b: 2

This is useful when you want to analyze letter occurrence without capitalization affecting the results.

Character Frequency Example

Suppose you enter:

banana apple

The counter analyzes the letters and shows how frequently each one appears. Spaces are excluded from the letter count.

This makes it easy to see repeated letters and compare their frequency across a word, sentence, paragraph, or other text.

Character Frequency vs. Word Frequency

Character frequency and word frequency measure different things.

A Character Frequency Counter analyzes individual letters, while a Word Frequency Counter shows how many times complete words appear in your text.

If you want to analyze repeated words instead of individual letters, use the Word Frequency Counter.

For the overall number of characters in a text rather than the frequency of individual letters, use the Character Counter.

When Is Character Frequency Useful?

Character and letter frequency analysis can be useful for studying writing patterns, checking repeated letters, analyzing text, language exercises, puzzles, and other situations where you need to know how often individual letters occur.

Because the results are generated automatically, you can analyze much longer text without manually counting every occurrence.
