Script to Minutes Calculator
Enter your script's word count — get audio length at three narration speeds, plus the credits it'll burn.
Planning the first question of every voiceover project: how long is this thing? Pair it with our cost calculator and you can budget time and money before the first render.
Tip: most word processors show this in the status bar. 1 page (double-spaced, 12pt) ≈ 250 words.
How these numbers work (honest method note)
These speeds are the industry-standard planning ranges narrators and producers use: ~130 wpm for deliberate long-form reads, ~150 wpm for standard narration, ~175 wpm for energetic short-form. They are planning estimates, not measurements of one specific tool — actual length varies with the voice, punctuation density, and pauses at sentence breaks.
That's why the workflow that works is: estimate here → render your first 200 words → measure the real ratio in that tool and voice → multiply. Our reviews log generation times on identical scripts, so you can calibrate against real renders in the ElevenLabs review and Murf review.
What changes your real length
- Punctuation pauses. A script with many short sentences renders longer than the same words in long flowing paragraphs — sentence breaks add real seconds.
- Numbers and acronyms. "1,250,000" is spoken as five words. Heavy stats scripts run longer than the raw word count suggests — one reason precision tools matter for e-learning and tutorials.
- Manual pauses and music beds. If you're adding breathing room in the editor (you should, for pacing), budget +10-20% beyond the render length.
FAQ
How many words is a 10-minute voiceover?
At the standard 150 wpm planning speed: about 1,500 words. Slow reads (audiobooks) fit around 1,300; energetic ad reads fit up to ~1,750.
How long does 500 words take to read aloud?
Roughly 3 minutes 20 seconds at standard speed — between 3:50 (slow) and 2:50 (fast). AI tools land close to these ranges because they're trained on human narration.
Is AI narration faster or slower than human narration speed?
About the same per word — AI voices are trained to human pacing. The difference is production time: a human narrator needs the full duration to record (plus retakes), while AI renders in a fraction of the audio length. Our measured workflows, not raw renders, are logged in the reviews.
How do I convert minutes back into a budget?
Take the minutes here, then feed them into our voiceover cost calculator — it converts audio minutes into credit costs using measured retry-burn rates, not sticker prices.
