What is Script to video length?
Talking-Head Length Estimator โ Convert script to video length: paste your talking-head script, set your speaking rate, and get an estimated duration range with pause allowance. Free.
Published timing formula, no AI: estimatedSec = ceil((units / rate x 60) x (1 + pause% / 100)), with rangeLow = ceil(estimate x 0.8) and rangeHigh = ceil(estimate x 1.2). Units are words at your speaking rate (default 140 wpm, allowed 60-250); CJK scripts are detected and counted by character at an estimated 300 chars/min. All results round up to whole seconds. Because speaking speed varies per person, the tool always reports a range โ an estimate, never an exact runtime.

Good to know
- The result is an estimate: speaking speed varies per person, so a range is always reported, never a single exact number.
- The 140 wpm default and 300 chars/min CJK rate are labeled estimates, not measurements of your voice.
- Pause allowance (default 10%) is a heuristic for breaths, beats, and emphasis pauses.
- CJK scripts are counted by character; mixed scripts fall back to whichever system dominates.
- Results are deterministic: the same script and settings always produce the same estimate.
