In today’s fast‑paced media landscape, a radio spot that cuts straight to the point can still capture attention and drive action. This guide gives you the exact word counts for 15‑, 30‑ and 60‑second slots, three full‑length scripts that you can copy and paste, and a customizable template to get you started.
Key Takeaways
- Focus on a single, crystal‑clear message—don’t try to cover everything in one ad.
- A 30‑second spot usually contains 75–85 words, so every word counts.
- Write with the ear in mind: short sentences, conversational rhythm, no jargon.
- Start with a hook that instantly grabs attention, then deliver a strong call‑to‑action (CTA).
- Professional voice‑over, music and sound design elevate credibility and recall.
What Is a Radio Spot?
A radio spot is a concise audio advertisement—typically 15, 30 or 60 seconds long—designed to promote a product, service, event or brand during commercial breaks. While most spots are pre‑recorded with voice‑over, music and sound effects, some are delivered live by a DJ or presenter for a more personal feel.
Radio spots come in several flavors:
- Fully produced commercial with voice‑over, music and effects.
- Live presenter‑read ad.
- Short sponsorship mention (e.g., “Traffic and travel brought to you by…”).
- Podcast‑style host‑read spot for online audio.
For a cohesive audio identity, consider how your radio spots fit with podcast production, jingles, DJ drops and other sonic branding elements. The UK industry body Radiocentre offers comprehensive planning and effectiveness guides for commercial radio campaigns.
How Long Should a Radio Spot Be?
The length you choose depends on the depth of your message, audience familiarity and placement. Avoid stuffing too much copy into a short slot—clarity beats volume.
15‑Second Spot: 35–40 words
Ideal for quick reminders, event announcements, limited‑time offers or brand mentions. The structure is one idea, one benefit, one CTA.
30‑Second Spot: 75–85 words
The most common format. It allows you to set up a problem, present a solution and finish with a clear CTA.
60‑Second Spot: 150–170 words
Use when you need to tell a short story, explain a service or create emotional resonance. Keep the narrative focused.
How to Write a Radio Spot
Unlike print or digital copy, radio script must be heard, not read. Listeners can’t skim or pause, so clarity and immediacy are paramount.
Write for the Ear, Not the Eye
Speak in natural, conversational language. Short sentences, simple words, and a rhythm that feels like spoken dialogue. Read the script aloud before finalising; any stumbling point is a red flag.
Steer clear of:
- Long feature lists.
- Technical jargon.
- Excessive numbers or URLs.
- Dense, unnatural sentences.
Replace any awkward phrase with something that rolls off the tongue.
Start with a Hook
The first 5–7 seconds are critical. Use a question, relatable problem, bold statement, sound effect or vivid scenario to capture the listener’s attention.
Keep It to One Message
Choose a single core idea and build the script around it. Ask yourself: What should the listener remember? What problem are we solving? What action do we want them to take? Why is this urgent now?
End with a Clear CTA
A single, straightforward CTA beats multiple options. Examples: “Visit our website today,” “Call now to book your free consultation,” or “Order before Friday and save 20%.”
