Precision timing for TikTok, Reels, and YouTube Shorts.
On TikTok and Reels, algorithms measure early retention ruthlessly. Viewers decide to stay or swipe within the first 3 seconds — that's roughly 10–12 words at a natural voiceover pace. Your Script Timer shows you exactly what those words are so you can make every single one earn its place. A weak hook means even a perfect video dies quietly. Start with conflict, a bold claim, a question, or a surprising visual cue your voiceover can hook into. Creators who obsess over their first 10 words consistently outperform those who start casually or with an intro.
Words Per Minute (WPM) is the foundation of accurate script timing. Conversational speech averages 130–145 WPM. High-energy creators like finance or tech TikTok run 155–175 WPM. Educators and storytellers slow down to 110–130 WPM to let ideas land. This tool offers four calibrated presets so you can match your actual delivery style instead of guessing. The fastest way to validate: read your script aloud with a timer and count words. That's your true WPM. Then set this tool to match, and your timing estimates become surgical.
Every platform has a different optimal and maximum length:
Short sentences hit harder on camera. Sentences over 20 words become difficult to deliver with energy and are harder for viewers to follow in a fast-paced format. Aim for an average of 10–14 words per sentence for short-form content. Long sentences work for storytelling and documentary-style content where a slower, more measured delivery is intentional. Use this tool's sentence count and average to audit your script rhythm. If your average is above 18, try breaking sentences apart. You'll be surprised how much more punchy and quotable your content becomes.
Two creators with the same 200-word script can produce videos that differ by 30 seconds purely based on delivery pace. Slow delivery feels authoritative and educational — great for finance, health, and self-improvement content. Fast delivery creates urgency and excitement — perfect for trend reaction, entertainment, and high-energy niches. Neither is wrong. What matters is intentionality: your pace must match your niche's expectations and your platform's dominant style. Use this tool to script to a specific target duration, then adjust your WPM setting until your real-world delivery matches.
