What is Online teleprompter?
Teleprompter — Use this free online teleprompter to time your script: set words-per-minute and font size, get read time plus a px/sec scroll plan. Start free.
Pure timing math, never AI: estimated read time = word count / words-per-minute x 60 (CJK scripts switch to characters-per-minute mode at wpm x 5, since they have no word spaces); scroll duration adds a 3-second lead-in buffer; the px/sec scroll rate assumes an 800px viewport, 0.55x average glyph width, and 1.5x line height — all documented estimates. Speeds outside 40-300 wpm are clamped with a warning. The scrolling viewport itself is UI; this tool only supplies the timing plan, so do a live read-through to calibrate before recording.

- 3Enter your teleprompter font size in px (12-120).
- 4Turn on mirror mode if you read through a beamsplitter rig.
- 5Run it to get word count, estimated read time, total scroll duration, and a px/sec scroll plan with calibration notes.

Good to know
- All timings are estimates from fixed formulas — a live read-through is required to calibrate your real pace.
- CJK reading speed (wpm x 5 chars/min) is a rough heuristic, not a measured rate.
- The px/sec scroll rate assumes an 800px viewport, 0.55x average glyph width, and 1.5x line height.
- Reading speeds outside 40-300 wpm are clamped to that range with a warning.
- Scripts over 10 minutes get a suggestion to split into sections; scripts over 20,000 characters are rejected.
How it works
Pure timing math, never AI: estimated read time = word count / words-per-minute x 60 (CJK scripts switch to characters-per-minute mode at wpm x 5, since they have no word spaces); scroll duration adds a 3-second lead-in buffer; the px/sec scroll rate assumes an 800px viewport, 0.55x average glyph width, and 1.5x line height — all documented estimates. Speeds outside 40-300 wpm are clamped with a warning. The scrolling viewport itself is UI; this tool only supplies the timing plan, so do a live read-through to calibrate before recording.
Examples
A 140-word script reads in about 60 seconds with a 63-second scroll plan.
Higher wpm shortens the duration; a larger font raises the px/sec scroll rate.
