Budget the spoken seconds first
Imagine a 30-second product tip with a three-second pause for a demonstration. That leaves 27 seconds for speech. At an illustrative pace of 150 words per minute, the word budget is 67 whole words: 27 × 150 ÷ 60, rounded down. This is a planning assumption, not a recommended speed for every speaker.
Open the script timer, set the target to 30, pauses to 3 and pace to 150. Paste only the words you intend to say. A 60-word script takes an estimated 24 seconds of speech and three seconds of pauses, leaving about three seconds within the target.
Measure your own pace with a short read
Choose a passage similar to the video you are making. Read it naturally and time the spoken delivery. A 90-word passage delivered in 45 seconds gives 120 words per minute: 90 ÷ 45 × 60. Enter that pace in the tool. The same 60-word script now needs 30 seconds of speech, before the planned pauses.
Decide whether your measurement includes deliberate gaps. If a timed read already includes a three-second demonstration, do not count the same gap again as a pause allowance. Use a short uninterrupted read to estimate speech pace, then budget demonstrations, breaths and on-screen reading separately.
Cut an idea before you accelerate the delivery
If the estimate exceeds the target, look for a second idea that belongs in another clip. Remove repeated setup, long introductions and instructions that the viewer can already see. Keep the evidence needed to support the main point. Speaking faster may make the number fit while making the explanation harder to follow.
For example, “In today’s video I am going to show you a useful way to prepare your next recording” can become “Choose one question before you record.” The shorter line makes a concrete promise. Follow it with an example that delivers that promise rather than several unrelated tips.
Write the words you will actually pronounce
A script containing “€1,250”, “API” or a long URL can take more speaking time than a simple word count implies. Write out the intended pronunciation when estimating. Remove stage directions such as “[show dashboard]” from the spoken text and include their duration in the pause allowance instead.
The timer counts letter-and-number word groups, keeps internal apostrophes and hyphens together, and ignores punctuation-only marks. That makes it useful for space-separated scripts, but it is not a language-aware speech model. For scripts without word spaces, or dense technical narration, rely more heavily on a real timed rehearsal.
Rehearse the final cut, not just the draft
Read the finished script aloud while performing the planned demonstration. Notice where you need another breath or where the viewer needs a moment to understand a visual. Adjust the script or the target length, then rehearse again. Leave enough time for the final instruction to be understood.
Keep the measured pace as a starting point for similar videos. A quiet explanation, a fast montage and a detailed tutorial can need different delivery. The calculator helps expose the trade-off between words and time; your recorded rehearsal is the final check.
