What it does
LetterCount is a free online character and letter counter for text such as short posts, messages and copy with a length requirement.
Type or paste the exact copy and choose Count Characters. By default LetterCount includes spaces and punctuation and counts a line break as one character. Options can instead exclude spaces and line breaks, punctuation or digits. Select the exclusions to match the destination's requirement, then compare with that destination's own counter when its rules differ. The tool is free; its related word-count and NATO spelling utilities are separate links.
