Key Takeaways
- 1Start with one specific viewer problem, a filmable action, and a visible payoff.
- 2A 30-second draft is about 75 spoken words at 150 words per minute, before pauses and visual-only moments.
- 3YouTube allows Shorts up to three minutes; Sumera currently offers 15, 30, 45, and 60-second Shorts presets.
- 4Check the finished video and retention report before attributing a result to the script.
Need a YouTube Shorts script you can actually film? Start with this four-line template. Replace the brackets with one specific idea, then read it aloud before you record.
Opening: "If [specific problem], try this."
Show: Demonstrate [one action] on camera.
Payoff: Show what changed and explain why.
Close: Give the viewer one thing to try next.
This is a writing aid, not a formula for views. The opening should match what the video really delivers, and the demonstration needs to be visible or clearly explained.
A 30-second script example
Imagine a cooking creator making a Short about burnt garlic. This is an illustrative script, not a published video or a claimed performance result:
Visual: A pan with dark garlic beside a pan with pale garlic.
Voice: "If your garlic turns bitter, check the heat before you add it."
Visual: Lower the heat, then add sliced garlic to oil.
Voice: "Keep it moving and watch for a light golden color. Take the pan off the heat before it turns brown."
Visual: Put the finished garlic next to the burnt batch.
Voice: "The difference is seconds. Try a lower heat on your next pan."
The visual comparison carries part of the explanation. If you remove the visual, rewrite the words so an audio-only viewer can still follow the point.
Pick a structure that fits the idea
Demonstration
Use problem → action → visible result → next step when the viewer needs to see a technique. Show the result early if the difference is otherwise hard to notice.
Question and answer
Use specific question → short answer → one reason → example for a factual explanation. Put the answer near the start. Check any claim before recording, especially health, money, or safety advice.
Small story
Use situation → decision → consequence → takeaway when the decision matters more than a list of tips. A real story needs real details. Do not invent a customer's result to make the ending dramatic.
If your idea needs several demonstrations or qualifications, split it into a series or choose a longer video. One clear payoff is easier to film and easier for a viewer to follow.
How long should the script be?
At a speaking pace of 150 words per minute, 15 seconds is about 38 spoken words, 30 seconds about 75, and 60 seconds about 150. Those are estimates, not ideal lengths. Visual-only moments, pauses, captions, and your actual delivery change the timing. Paste a draft into our free script timer and then read it aloud with the planned shots.
YouTube allows Shorts up to three minutes. Sumera's current YouTube Shorts generator presets are 15, 30, 45, and 60 seconds. That is a product choice, not YouTube's maximum. For a longer Short, write in sections and check the total timing yourself.
A brief you can give to an AI script generator
Copy this brief and replace the brackets:
Copyable brief: Write a 30-second YouTube Short for [specific viewer]. The one useful takeaway is [claim or action]. Start by showing [visual proof or concrete problem]. Include [what the camera can actually show]. Avoid [unverified claim or unwanted tone]. End with [useful next action]. Mark voiceover and on-screen action separately.
Review the draft against four questions:
- Does the first shot or line make the topic clear without a long introduction?
- Can you film every action the script calls for?
- Are the facts and promised result accurate?
- Does the spoken script fit when you read it at your natural pace?
If the draft fails any one of these, revise the brief and try again. AI can suggest a structure, but it cannot verify your footage or your result. Generate a 30-second Shorts draft in Sumera when you have a specific brief. The generator is part of Sumera's card-required Starter trial; the script timer above is free.
Improve the next video with real evidence
After publishing, look at the video's audience-retention report in YouTube Studio. A dip does not prove that one line of the script failed, and a spike can mean a moment was rewatched or unclear. Compare the graph with the actual footage, title, thumbnail, and traffic source before changing the next script. Our retention-graph worksheet shows how.
For longer videos, see the YouTube script template and scriptwriting guide. A longer video needs more context than this single-idea Shorts template.
Frequently Asked Questions
How do I write a YouTube Shorts script?
Choose one specific takeaway, open with a concrete problem, show one action or answer, and end with a useful next step. Write the voiceover and on-screen action separately, then read the draft aloud.
How many words fit in a 30-second Short?
At 150 spoken words per minute, 30 seconds is about 75 words. Your actual pace, pauses, and visual-only shots change the length, so time a read-through before filming.
Can a YouTube Short be longer than 60 seconds?
Yes. YouTube allows Shorts up to three minutes. Sumera currently offers 15, 30, 45, and 60-second Shorts generator presets, which are separate from YouTube’s platform limit.
