A words to minutes calculator tells you how long a script takes to read aloud. At the average US English speaking rate of about 150 words per minute, a 1-minute script is about 150 words, a 30-second ad is about 75 words, and 1,000 words take about 6 minutes 40 seconds. Paste your script below to time it at your own pace.
Key Takeaways
- Spoken length = word count ÷ words per minute. At 150 wpm, 150 words take 1 minute.
- A 15-second spot fits about 35–40 words, a 30-second spot about 75, and a 60-second script about 150.
- Slow down for phone prompts and training (about 130 wpm). Speed up a little for ads and social clips.
- Audiobook narrators average about 9,300 words per finished hour, roughly 155 wpm.
- With an AI voice, you can change speed after writing, so write for the length first, then fine-tune.
How many words fit in each video or ad length?
Use this table when you plan a script. It shows the word budget at three paces.
| Length | Slow and clear (130 wpm) | Average (150 wpm) | Brisk (170 wpm) |
|---|---|---|---|
| 15 seconds | 33 words | 38 words | 43 words |
| 30 seconds | 65 words | 75 words | 85 words |
| 60 seconds | 130 words | 150 words | 170 words |
| 90 seconds | 195 words | 225 words | 255 words |
| 2 minutes | 260 words | 300 words | 340 words |
| 3 minutes | 390 words | 450 words | 510 words |
| 5 minutes | 650 words | 750 words | 850 words |
| 10 minutes | 1,300 words | 1,500 words | 1,700 words |

Which pace should you plan for?
Pick the pace from the job the audio does, not from how fast you read silently.
Plan for: brisk, about 170 wpm, but leave room. A 30-second radio or social spot holds about 75–85 words at that pace. For streaming audio ads, Spotify recommends no more than 65 words for 30 seconds and about 100 words for 60 seconds, which leaves room for music and a clear call to action. Hook in the first 3 seconds and say the brand name early.
Plan for: average, about 150 wpm. A 10-minute video needs about 1,500 words of narration. Explainers usually run slightly slower around key terms, so budget 10% fewer words if you show text or diagrams on screen.
Plan for: slow and clear, about 130 wpm. Learners take notes and read on-screen text at the same time. A 5-minute module holds about 650 words. Split anything longer into short sections that each make one point.
Plan for: slow and clear, about 130 wpm. Callers often write down hours, numbers or options. Keep a main greeting under 30 seconds, which is about 60–65 words. See our phone greeting and IVR script library.
Plan for: about 155 wpm. ACX, Audible’s production marketplace, says most narrators read about 9,300 words per finished hour. A 60,000-word book comes to about 6.5 hours of audio.

Try your script freeHow to hit an exact length with an AI voice
- Write to the word budget from the table, a few words under the target.
- Paste the script into Kveeky and choose a voice that suits the format.
- Generate and check the real length in the downloaded MP3 or WAV.
- Fine-tune the speed between 0.5× and 2×. Small changes, such as 0.9× or 1.1×, sound natural.
- Cut words rather than rushing if you are more than 10% over. Fast reads lose listeners.
Pauses add time too. A full stop, a comma or a new paragraph all change the rhythm. Our guide on pauses, emphasis and pacing shows how to control them.

The formula behind the calculator
Speaking time in minutes = number of words ÷ words per minute.
For example, a 450-word script at 150 wpm takes 450 ÷ 150 = 3 minutes. To find a word budget, reverse it: words = minutes × words per minute. A 45-second slot at 150 wpm holds 0.75 × 150 ≈ 112 words.
When you change AI voice speed, multiply the pace by the speed. At 1.2×, a 150 wpm voice reads about 180 wpm, so the same script is about 17% shorter. This is an estimate, because some voices stretch pauses differently.
Before you record: quick checklist
| Check | Why it matters |
|---|---|
| Script is under the word budget | Leaves room for pauses and a clear ending |
| Numbers, dates and prices written as you want them said | AI voices read “$1.5M” differently from “one and a half million dollars” |
| Brand and product names tested once | Fix pronunciation before you generate the full script |
| Call to action read slowly | Phone numbers and web addresses need extra time |
| Audio made on a paid plan if it promotes a business | Paid Kveeky plans include commercial usage rights |
Frequently asked questions
How many words is a 1-minute speech?
About 150 words at an average US English speaking rate. A slower, clearer read is about 130 words, and a brisk read is about 170.
How long does it take to read 1,000 words aloud?
About 6 minutes 40 seconds at 150 words per minute. At a slow 130 wpm it takes about 7 minutes 42 seconds.
How many words should a 30-second ad script be?
About 75 words at an average pace. For streaming audio ads with music, Spotify recommends no more than 65 words for 30 seconds.
How do I calculate how long my script will take?
Divide the word count by the words per minute. For example, 600 words ÷ 150 wpm = 4 minutes.
How many words is an hour of audiobook?
ACX says most narrators average about 9,300 words per finished hour, which is roughly 155 words per minute.
Does AI voice speed change the length?
Yes. Raising the speed shortens the audio and lowering it lengthens it. In Kveeky you can set speed from 0.5× to 2× after you write the script.
