Frequently Asked Questions
What is a letter counter?
A letter counter is a tool that counts how many times each letter or character appears in a given piece of text. It provides a frequency analysis, showing the count and percentage for each character, often sorted by frequency or alphabetically.
What is the most common letter in English?
The letter E is the most common in English, typically making up about 12-13% of all letters. It is followed by T (9%), A (8%), O (7.5%), and I (7%). This is why E is the hardest letter to avoid in constrained writing like lipograms.
Is this letter counter case-sensitive?
By default, the tool counts A and a as the same letter (case-insensitive mode). You can toggle to case-sensitive mode using the Aa≠aa button, which will count uppercase and lowercase letters separately.
Can I count digits and punctuation too?
Yes. By default, the tool counts letters only (A-Z). Click "All chars" to include digits (0-9), spaces, punctuation marks, and any other characters in the frequency analysis.
How do I export the results?
Click the "Download CSV" button to export the full character frequency analysis as a CSV file that you can open in Excel, Google Sheets, or any spreadsheet application.
What is character frequency analysis used for?
Character frequency analysis is used in cryptography (breaking substitution ciphers), linguistics (studying language patterns), typography (type design and kerning), SEO (keyword density), game design (Scrabble tile values), and natural language processing.
