Word Count

Required integer input.

Duration Seconds (s)

Subtitle reading speed in words per minute from displayed word count and on-screen duration. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Words Per Minute (words/min)

The resulting words per minute returned as a number.

• Characters-per-second is only one readability measure. Language, word length, shot changes, line breaks, line count, reading level, accessibility rules, timing, and dialogue density determine acceptable subtitles.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Confirm critical values with the actual camera, lens, codec, projector, and delivery specification, then run a camera or projection test under representative conditions.

• Subtitle Characters Per Second

  Subtitle reading load as visible character count divided by the subtitle's on-screen duration.

• Box Office Gross Per Screen

  Gross theatrical receipts per playing screen from a total gross and positive screen count.

• Screen Count Required
