15s, 30s or 60s: matching jingle length to placement and funnel stage
SingingAds writes every jingle to an exact length: 15, 30 or 60 seconds, with the lyrics fitted to the time, so nothing has to be chopped to make it fit. You choose the length, paste a product page, approve lyrics that only use your page's claims, and get a 9:16 video ad and the song, both cut to that length.

What fits in each length
A sung line takes a few seconds at a typical ad tempo, so length decides how much story you get. Roughly: a 15 holds two or three sung lines (the problem, the name, the ask). A 30 holds about five to seven: a short verse, a chorus with the name and benefits, and a call to action. A 60 holds about ten: a full verse that sets the scene, a chorus, and room for more proof before the ask.
More lines than the length can hold makes the singer rush and the ending get cut, so the lyrics are written to the line count the length allows.
Which length for which job
- 15 seconds: retargeting, cutdowns of a winning 30, Stories, and a sung tag for radio or podcasts. People who already know you need a reminder, not a story.
- 30 seconds: prospecting on TikTok, Reels and Shorts. Long enough to make a stranger care, short enough to hold them.
- 60 seconds: radio spots, YouTube, podcast breaks and products that need a little explaining.
Shorter than 15? That is a sonic logo, not a jingle; see sonic logos for how to trim one from a take.
Platforms do not force the length
Length is a creative choice, not a spec. TikTok's in-feed spec allows non-Spark video ads up to 10 minutes, and Meta's Reels spec allows from 0 seconds up to 15 minutes. What limits you is attention. Start with a 30 for cold audiences, and cut a 15 when you have a winner to remind people of.
Radio is the one place where length is fixed by what you buy: stations sell spots by the second, so make the take match the slot. The song file downloads on its own for that, as covered on the jingle generator page.
Why it is written to length, not cut down
Cutting a long song down leaves you with a chorus that starts mid-breath or an ending that fades on nothing. Writing to length means the hook opens the song, the name falls in the chorus where the ear expects it, and the call to action is the last thing sung. The video is cut to that song, one shot per sung line, so the pictures change exactly when the words do.
Credits by length
A typical finished video ad uses about 18 credits at 15 seconds, 26 at 30 seconds and 44 at 60 seconds, counting the song, the storyboard and animated shots. Animating fewer shots uses fewer. A sung take on its own costs 4 credits at any length. Packs are on pricing.
Illustrative example: one product at 15 and 30 seconds
Product: Tidewell, a fictional reusable water bottle. The page says "keeps water cold for 24 hours" and "fits in a bike cage".
15 seconds: My water's warm by second lap / Tidewell keeps it cold all day / get yours at Tidewell.
30 seconds: My water's warm by second lap / I'm drinking soup by mile nine / Tidewell, cold for twenty-four hours / slides right into my bike cage / last climb, still ice in my hand / get yours at Tidewell.
The 15 is for people who saw the 30 last week.
What it can't do
- Lengths are 15, 30 and 60 seconds only; there is no 6-second or 90-second option.
- A 15 cannot hold a full story; if the product needs explaining, use 30 or 60.
- Line counts are approximate and depend on the song's tempo.
What it costs
From $15 for one ad, or $59 for about 6 thirty-second video ads. Credits never expire. A jingle take costs 4 credits; a typical 30-second video ad about 26. There is no free tier and no free sample.

Questions
- Can I make a 6-second bumper?
Not directly. The shortest is 15 seconds. You can trim the last sung line from the audio file for a very short sting.
- What happens if my lyrics are too long for the length?
The writer fits the lyrics to the line count your length holds. If you add lines by hand, keep to that count or choose a longer length, or the singer has to rush.
- Should I make the 30 or the 15 first?
For cold audiences, the 30. Once a version wins, a 15 that keeps the same hook and name works as the reminder.
- Which length suits Stories?
A 15 suits places where people tap through quickly, such as Stories. Use the 30 where people are already settled in and watching, such as the main Reels or TikTok feed.
- Can I make all three lengths of one ad?
Yes, make one ad per length from the same page. Each is written fresh to its length, so the lines change; keep the same hook if you want them to feel like one campaign.
- Does a 60-second jingle cost much more?
More, because there are more shots to draw and animate. The song itself costs the same at every length.
