About this tool

Estimate subtitle line count from text length and a maximum characters-per-line limit. This focused video utility gives editors, creators, students, and production teams a quick way to plan media settings before exporting or sharing a clip. Enter the requested values to see a clear result immediately. The calculation runs locally in your browser and does not require selecting or uploading a video file.

Use the result as a practical planning guide, then confirm final settings in your video editor or playback environment.
