A script can look short on the page and still run long once it is spoken aloud. Speaking time depends on word count, delivery pace, pauses, and the style of the video, which is why estimating runtime before production helps keep UGC ads, TikToks, Reels, and product demos on brief.
Use the video script speaking time analyser to decide whether your hook fits a 15-second slot, whether your product explanation needs trimming for a 30-second ad, or whether a longer creator read should be split into multiple scenes. It is a practical planning step before recording, briefing creators, or generating AI video.
Lumafly's free Speaking Time Calculator helps creators and marketers estimate how long a video script, speech, voiceover, or UGC ad takes to read aloud. Plan 15, 30, and 60 second short-form videos before you record, generate, or brief a creator.
Word count
Instant count of words, characters, sentences, and paragraphs in your script.
Speaking speeds
Four hardcoded WPM presets from slow explainers to fast UGC creator delivery.
Ad length fit
See whether your script is under, close to, or over common short-form video slots.
Drop in your UGC ad script, talking-head video copy, or social video narration.
Choose slow, conversational, fast, or UGC/TikTok delivery to match your creator style.
See estimated runtime and whether your script fits 15, 30, 60, or 90 second placements.
Use this free speaking time calculator for UGC ad scripts, TikTok hooks, YouTube Shorts, Reels, product demos, webinar intros, podcast ads, and sales videos. Paste your script and compare the estimated read time against the placement you need to hit before anyone records or generates the final video.
Speaking time is not only word count. Pauses, delivery style, emphasis, product shots, transitions, and on-screen actions all affect the final runtime. A creator reading a fast TikTok-style script may land closer to 180 words per minute, while a founder-led explainer or tutorial often needs a slower pace so viewers can process the message.
If the script runs long, trim repeated setup, remove filler phrases, and move secondary proof points into captions or overlays. If the script is too short, add a clearer hook, a stronger problem statement, or a short call to action instead of padding the script with generic language.
Best for a direct hook, one benefit, and one CTA. Keep the script tight and avoid explaining every feature.
Useful for a hook, problem, product moment, proof point, and CTA. Most UGC ads should still read naturally rather than rushing through every line.
Works for demos, founder explanations, testimonials, and educational angles. Use scenes or pauses so the script does not feel like one long paragraph.
Better for detailed explainers, onboarding videos, and sales assets. Split longer scripts into sections so viewers can follow the story.
