Letter Counter
Count individual letters and character frequencies in text.
Frequently Asked Questions
What does the letter counter show?
The letter counter analyzes your text and displays a frequency table showing each character, its count, and its percentage of the total. It separates letters, numbers, spaces, and special characters into organized sections so you can quickly find the information you need.
Is the count case-sensitive?
By default, the tool counts uppercase and lowercase letters separately (A and a are two different entries). You can toggle case-insensitive mode to merge them into a single count. In merged mode, the total combines both cases under the lowercase letter.
What is letter frequency analysis used for?
Letter frequency analysis is used in cryptography (breaking substitution ciphers), linguistics (studying language patterns), writing analysis (identifying author style), SEO (keyword density), and education (teaching probability and statistics with real-world text data).
Does it count spaces and punctuation?
Yes — every character in your text is counted including spaces, punctuation marks, numbers, and special characters. The results are categorized so you can focus on just letters, just numbers, or see the complete character breakdown.
Can I sort the results by frequency?
Yes — you can sort the frequency table alphabetically or by count (most frequent first). Sorting by frequency is useful for identifying the most common characters in your text, which is particularly helpful for cryptanalysis and linguistic research.
