A subtitle character counter gives you live character, word, and line counts for your captions, and flags any line that runs past a readable per-line limit. It is the quickest way to make sure your subtitles fit on screen and stay readable instead of getting cut off or running into two crowded lines.
Caption readability has hard limits. Platforms and accessibility guidelines recommend keeping lines short — roughly 32 to 42 characters — so text fits comfortably and viewers can read it at speed. Going over means lines wrap awkwardly or get truncated on smaller screens.
Paste your captions and watch the counts update as you type, with over-limit lines highlighted. Free, no signup.
