Teleprompter Scroll Speed: How Fast Should a Teleprompter Scroll?
The right scroll speed for a teleprompter is whatever moves the text at exactly the rate you speak, and that is the whole problem: you do not speak at one rate. You slow down on the important line, speed up through the list, stop to think, and restart. A fixed scroll speed is a bet that you will do none of those things. This post explains what a scroll speed actually is, how to set one if you have to, and how to avoid having to.
Scroll speed is words per minute wearing a disguise
Every prompter's speed slider, whatever units it shows, resolves to one real quantity: how many words pass the reading line each minute. That number has to equal your speaking pace or the text and your voice drift apart. Most people speak at 120 to 160 words per minute in conversation, presenters and YouTubers at 130 to 160, and formal speakers with pauses at 100 to 130. If you do not know yours, the WPM reading test measures it in about a minute.
Converting pace into lines per minute
Speed sliders are arbitrary, but lines are not. If you know your pace and how many words fit on a line at your text size, you know how many lines must scroll past per minute.
| Speaking pace | 6 words per line | 8 words per line | 10 words per line |
|---|---|---|---|
| 110 wpm (deliberate) | 18 lines/min | 14 lines/min | 11 lines/min |
| 130 wpm (live speech) | 22 lines/min | 16 lines/min | 13 lines/min |
| 140 wpm (conversational) | 23 lines/min | 18 lines/min | 14 lines/min |
| 160 wpm (presenter) | 27 lines/min | 20 lines/min | 16 lines/min |
| 180 wpm (brisk) | 30 lines/min | 23 lines/min | 18 lines/min |
To turn that into a setting on a fixed-speed prompter: count how many lines are visible on screen, time how long one full screen takes to scroll past at the current setting, and adjust until the lines-per-minute figure matches your row. The scroll speed calculator does the arithmetic from your pace, font size, and screen height.
Why the number on the slider means nothing
Two prompters set to “speed 5” scroll at different rates. Change the font size and the same setting moves twice as many words per minute. Change the window width and the line count changes again. A setting only means something for one script, one font, one screen, and one speaker, which is why a fixed speed has to be re-tuned every session and why the first thirty seconds of most recordings are a speed adjustment.
Setting a fixed speed as well as it can be set
- Measure your pace with a real read-aloud, not a guess.
- Format the script in short lines so the words-per-line figure is stable.
- Set the speed so the reading line reaches the end of the first paragraph exactly when you do, then leave it.
- Rehearse the whole script once at that speed. If you drift, change your delivery, not the speed; you will not be able to change the speed mid-take.
- Accept that any pause longer than a breath will cost you a retake.
The way to skip the problem
A voice-controlled teleprompter has no speed setting because it does not need one. Speech recognition matches the words you say to the words in the script and moves the text to keep the current word centred. Speak faster and it keeps up; stop and it waits; skip a sentence or repeat one and it re-syncs. Sayscroll works this way in 60+ languages, in the browser, with nothing to install. Its auto-scroll page explains how voice-paced scrolling compares to a timer if you have only ever used the fixed-speed kind.

Frequently asked questions
What is a good teleprompter speed?
One that matches your speaking pace, usually 120 to 160 words per minute. Because speed sliders use arbitrary units, convert to lines per minute using your font size, or use a voice-following prompter that sets the pace from your speech.
How do I calculate teleprompter scroll speed?
Divide your words per minute by the number of words on a line to get lines per minute, then adjust the slider until a full screen of lines scrolls past in the right time. The scroll speed calculator does this for you.
Why does my teleprompter keep getting ahead of me?
Because you paused, slowed down, or the speed was set for a faster read. Fixed-speed scrolling cannot wait. A voice-controlled prompter pauses when you pause and resumes when you speak, so it cannot get ahead.
Does Sayscroll have a scroll speed setting?
No. It follows your voice word by word, so there is nothing to set. You can also scroll by hand at any time to skip ahead or go back, and the prompter simply continues from the line you scroll to.
