Teleprompter Speed: What WPM Should You Set?

Start at 140 words per minute. That's the default in ReadCalc's teleprompter and it's the right first guess for almost everyone, because it sits in the middle of the band that research puts prepared delivery in.

But 140 is a starting point, not a setting you leave alone. The right speed depends on the format you're recording, how familiar the script is, and — more than most people expect — how nervous you are on the first take.

Why 140 and Not 150 or 180

Most published averages for speaking rate describe conversation, not delivery. The commonly quoted 150 WPM figure comes from studies of casual talk, where you're interrupted, corrected and interrupted again. A teleprompter read has none of that. There's no correction channel, so the pace has to carry the comprehension margin on its own.

Tauroza and Allison's work on speech rates put average prepared speech at 125–160 WPM. 140 is the midpoint. It's covered in full in what the research says about average speaking rate, but the practical version is: a slider set at 140 will feel slightly slow while you're reading and sound completely normal on playback. That mismatch is the single most common reason people set the speed too high.

Speed by Format

The slider runs from 80 to 220 WPM in steps of 5. Where you sit inside that depends on what you're making:

Format	Set it to	Why
Tutorial / how-to	120 – 130	Viewer is following steps, often while doing them
Talking head, general	135 – 145	The default case
Corporate / explainer	130 – 145	Dense information, unfamiliar terms
YouTube, conversational	150 – 165	Audience expects energy; they can rewind
Ad read / promo	150 – 170	Short, familiar, high-energy
News-style delivery	170 – 190	Only works with copy written to be heard
Legal, medical, safety	110 – 125	Precision matters more than pace

The news-style band at the top is real but conditional. Broadcasters sustain 190 WPM because their copy is built for it — short sentences, one idea each, names before facts. Push a subordinate-clause-heavy script to 190 and you'll lose the audience, not impress them. If you want the top of the range, the script has to earn it first.

Set the Font Size Before the Speed

These two settings interact, and people usually adjust them in the wrong order.

The font size slider runs 22–80px, defaulting to 42. Larger text means fewer words visible at once, which means you're reading closer to the leading edge of the scroll with less runway to see what's coming. At a large size you'll want a slightly slower speed than the same script at a smaller one — not because you read slower, but because you can see less ahead.

Set your distance from the screen first, then the font size so the text is comfortable at that distance, then the speed. Adjusting speed to compensate for text you can't quite read is how people end up at 110 WPM wondering why their delivery sounds flat.

Calibrate Once, on Your Own Voice

The published averages get you close. Your own measured rate gets you right, and it takes one take to find.

Load a script you know into the teleprompter, set it to 140, and record. If you're consistently arriving at the bottom of each line before the scroll does, you're faster than 140 — nudge up in steps of 5 and re-record. If you're clipping words to keep up, come down. Two or three passes will land you within 5 WPM of your natural pace, and that number holds across most of what you record.

One caveat: your first take is not representative. Nerves push almost everyone 10–15 WPM faster than their settled pace, which is why a speed that felt perfect on take one feels sluggish on take four. Calibrate on a take where you've stopped thinking about the camera.

Keyboard Controls

Key	Action
↑ / ↓	Speed up / slow down mid-read
F	Full screen
M	Mirror mode, for beam-splitter rigs
Esc	Exit

The arrow keys are the useful ones. Being able to adjust without stopping means you can fix a speed that's slightly off in the take rather than resetting and starting again. Turn on Auto-hide Controls so the interface disappears once you start, and Countdown (3s) if you need a beat to settle before the text moves.

Getting the Script Right First

Speed can only do so much. If a script runs long at 140 WPM, the fix is the script, not the slider — pushing to 165 to make a five-minute slot is audible, and it's the first thing that makes a read sound rushed.

Work out the real duration before you record. The script formatter inserts timestamp markers at a set interval so you can see where you'll be at each minute, and timing a script properly covers the whole process. If the numbers say you're over, cut words rather than raising the pace — the difference between reading and speaking rate is bigger than most people plan for, which is why speaking time and reading time diverge so sharply.
