How Long Is 5,000 Characters? Words, Pages and Speaking Time
5,000 characters is about 800 words, a page and a half of text, or five to six minutes of speech. A table of characters, words and speaking time for any script.
Short answer5,000 characters, counting spaces, is roughly 750 to 850 English words, about a page and a half of single-spaced text, and five to six minutes of speech at a natural pace. As a rule of thumb, an AI voice speaks about 15 characters, or two and a half words, per second.
Text to speech apps measure scripts in characters, while people think in words, pages and minutes. Voice Labs takes up to 5,000 characters in one generation, so here is what that looks like in terms you can plan with.
The quick conversions
A character is any letter, digit, space or punctuation mark. For ordinary English prose:
- Characters to words: divide by 6.
- Words to speaking time: divide by 150 to get minutes, or by 2.5 to get seconds.
- Characters to speaking time: divide by 15 to get seconds.
These are averages. Text full of long technical words has fewer words per thousand characters, and a slow, dramatic read takes longer than a quick one.
One real data point: in the Voice Labs App Store screenshots, a 291-character story opening plays in 19 seconds. That works out at just over 15 characters per second, which is where the rule of thumb comes from.
Characters, words and time
| Characters | Words (approx.) | Speaking time | That is about |
|---|---|---|---|
| 100 | 15 to 18 | 7 seconds | A hook |
| 230 | 35 to 40 | 15 seconds | A short ad or a story intro |
| 450 | 70 to 80 | 30 seconds | A standard ad, a short Reel |
| 900 | 140 to 160 | 1 minute | A full short-form video |
| 1,800 | 280 to 320 | 2 minutes | A product explainer |
| 2,700 | 430 to 470 | 3 minutes | A long Short, a lesson segment |
| 5,000 | 750 to 850 | 5 to 6 minutes | A bedtime story, a chapter section |
| 10,000 | 1,550 to 1,700 | 11 minutes | Two generations |
| 30,000 | 4,700 to 5,100 | 33 minutes | Six generations |
What fits in one 5,000-character generation
- A complete script for any TikTok, Short or Reel, many times over
- A five-minute YouTube section
- A picture book or a short bedtime story
- Around ten slides of lesson narration
- A 60-second ad in five different versions
- About a page and a half of single-spaced text
How to check your script’s length
You do not need a separate tool. Paste the script into Voice Labs and the counter under the text shows how many of the 5,000 characters you have used. Most writing apps also show a character count: look under Word Count in Pages, Word or Google Docs, and make sure you read the figure that includes spaces.
Working with scripts longer than 5,000 characters
Long scripts are generated in parts. Done carefully, nobody will hear the joins.
- Split at natural breaks. End each part at the end of a paragraph, scene or section, never mid-sentence.
- Leave a little headroom. Aim for about 4,500 characters per part so you have room for a small edit without re-splitting.
- Use the same voice and settings every time. Note the voice name, the preset and the three slider values before you start.
- Number the parts. Save the audio as 01, 02, 03 so the order survives the trip to your editor.
- Listen across each join. Play the last sentence of one part into the first of the next. If the tone shifts, regenerate the shorter of the two.
- Add the pause yourself. Put half a second to a second of silence between parts in your editor.
Planning a script backwards from time
Most projects start with a duration, not a character count. Work backwards:
- Short-form video, 20 seconds: 50 words, about 300 characters
- Podcast intro, 15 seconds: 40 words, about 230 characters
- Explainer, 90 seconds: 225 words, about 1,350 characters
- Lesson slide, 40 seconds: 100 words, about 600 characters
- Bedtime story, 5 minutes: 750 words, about 4,500 characters
Write to the word count, generate, and check the time shown in the player. If it runs long, cut words. Raising the speed to squeeze a script into its slot makes it harder to follow, which defeats the point of having a voiceover.
Other languages
The six-characters-per-word rule is for English. Languages with longer average words, such as German or Finnish, fit fewer words into 5,000 characters, and languages written without spaces between words, such as Japanese, pack far more meaning into each character. Speaking rates differ too. For any language other than English, the practical method is to generate one paragraph, note how long it runs, and scale from there.
