How long should a song be? Song length and section timing
Published
Most songs run 2:30–3:30. Intro, verse, chorus and bridge lengths in bars and seconds, the BPM formula, and lengths for radio, streaming and weddings.
A song should last as long as its idea needs, but most pop songs today run about 2:30 to 3:30, and anything from two to four minutes sounds normal. Sections are counted in bars: an intro is usually 4–8 bars, a verse 8–16, a pre-chorus 4–8, a chorus 8 and a bridge 8. To turn bars into seconds, use seconds = bars × beats per bar × 60 ÷ BPM: a 16-bar verse in 4/4 at 90 BPM lasts 16 × 4 × 60 ÷ 90 = 42.7 seconds. On streaming, bring the voice in early, because Spotify only counts a play after 30 seconds. For radio, weddings and auditions, cut to the section the moment needs.
Below: section lengths at three tempos, the formula with audio to check it against, the length each context asks for, and three timed song maps.
Section lengths in bars and seconds
In 4/4, one bar lasts 240 ÷ BPM seconds: 3 seconds at 80 BPM, 2.4 at 100 and 2 at 120.
| Section | Typical bars | At 80 BPM | At 100 BPM | At 120 BPM |
|---|---|---|---|---|
| Intro | 4–8 | 12–24 s | 9.6–19.2 s | 8–16 s |
| Verse | 8–16 | 24–48 s | 19.2–38.4 s | 16–32 s |
| Pre-chorus | 4–8 | 12–24 s | 9.6–19.2 s | 8–16 s |
| Chorus | 8 | 24 s | 19.2 s | 16 s |
| Bridge | 8 | 24 s | 19.2 s | 16 s |
| Outro | 4–8 | 12–24 s | 9.6–19.2 s | 8–16 s |
Two things follow. The same 8-bar chorus lasts 24 seconds in a slow song and 16 in a fast one, so “how long is a chorus” has two answers: 8 bars, or roughly 15 to 25 seconds. And a slow song needs fewer bars to fill three minutes. Each part has its own guide: verse, pre-chorus, chorus and bridge. The song structure guide explains what each section does and compares the common forms.
How to work out a song’s length from bars and BPM
seconds = bars × beats per bar × 60 ÷ BPM If BPM is new to you, start with what BPM means in music.
Beats per bar is 4 in 4/4 and 3 in 3/4. In 6/8, convert the pulse to quarter notes first (a dotted-quarter pulse of 90 is 135 quarter notes per minute) and use 3.
Worked example, a 16-bar verse in 4/4 at 90 BPM:
- Beats in the section: 16 × 4 = 64.
- Seconds per beat: 60 ÷ 90 = 0.667.
- Length: 64 × 60 ÷ 90 = 3,840 ÷ 90 = 42.7 seconds.
Turn it around to plan a length: bars = seconds × BPM ÷ (60 × beats per bar). A three-minute song (180 seconds) in 4/4 holds:
| Tempo | Bars in 3:00 |
|---|---|
| 80 BPM | 60 |
| 100 BPM | 75 |
| 120 BPM | 90 |
| 140 BPM | 105 |
If you don’t know the tempo, tap along with the recording on the free tap tempo metronome and read the BPM. The free song structure planner does the rest: add your sections and bars, set the tempo and time signature, and press “Calculate section durations” to see each section’s length and the estimated total. It uses this same formula, runs in your browser and saves nothing.
Check the formula by ear
This example plays five sections of four bars each at 100 BPM. By the formula, each section lasts 4 × 4 × 60 ÷ 100 = 9.6 seconds.
What to listen for: after the count-in, the verse runs 0:02–0:12, the pre-chorus 0:12–0:21, the chorus 0:21–0:31, the bridge 0:31–0:40 and the last chorus 0:40–0:50. A new section arrives about every 9.6 seconds, exactly as the formula predicts: 20 bars, 48 seconds of music. It is a short synthesized teaching example, so each section is half the usual size. Double the bars and you have a real 8-bar chorus of 19.2 seconds.
What to listen for: the four chords play twice, eight bars in all. At 96 BPM one bar lasts exactly 2.5 seconds, so from the end of the count-in (about 0:02) to the last chord the music takes 20 seconds. That is the length of a typical 8-bar chorus at this tempo. Count “1-2-3-4” along with it to feel how long eight bars really is.
Why songs got shorter, and why it isn’t a straight line
Song length has always followed the format. Chartmetric notes that 78 rpm records kept their best sound quality for only three to five minutes per side, which fits the short songs of that era. By the 1990s the average song had grown to 4:14.
Streaming pushed lengths back down. Spotify counts a stream once someone has listened for at least 30 seconds, so a two-minute song earns a play just like a five-minute one, and a shorter song fits more plays into an hour of listening. Chartmetric’s 2024 analysis found that the average Spotify charting song ran about three minutes, nearly 15 seconds shorter than in 2023 and 30 seconds shorter than in 2019. Short-form video adds its own pressure: many people first hear a song as a clip, so the hook has to work out of context.
But the trend isn’t a straight line. Billboard and Hit Songs Deconstructed found that in 2024 the average top 10 hit on the Hot 100 got longer, by more than 20 seconds, to 3:40, and nearly 23% of those hits took over a minute to reach the chorus, the highest share in a decade. Different charts give different answers, so treat 2:30–3:30 as the center, not a rule. For how plays turn into money, see songwriting royalties explained: no service pays a fixed rate per stream.
How long a song should be in each context
Radio edit
There is no official length. A radio edit is a shorter version that sits close to the other songs on the playlist, which today means roughly the chart averages above, about 3:00 to 3:40. The usual cuts:
- The intro, down to 2–4 bars. At 100 BPM, cutting an 8-bar intro to 4 saves 9.6 seconds.
- A repeated section, such as the second pre-chorus or a doubled chorus.
- A long solo: 16 bars at 140 BPM is 27.4 seconds.
- The fade-out, replaced by a clean ending.
Cut on section boundaries so the edit can’t be heard, and ask the station or promoter whether they have guidelines.
Streaming
There is no length rule, but the 30-second threshold shapes the start: a listener who skips at 0:20 does not add a stream. Bring in the voice or the hook within the first 15 seconds or so. Distributors such as DistroKid also let you choose where the preview clip starts, so point it at the chorus. Song length also decides how stores label your release: see how many songs on an EP.
TikTok, Reels and Shorts
Here the song is heard as an excerpt, not whole. YouTube allows Shorts of up to three minutes and says most songs can be used for up to 90 seconds in a Short, with some tracks limited to 60 or 30 seconds. So write at least one section that works alone. An 8-bar chorus at 120 BPM lasts 16 seconds, 16 bars last 32, and the hook should land inside that window.
Live
Live, a song can stretch: a longer intro while the band settles, an extra chorus when the room sings, a solo. What matters is the whole set: songs that fit = stage time ÷ (average song length + gap between songs). How to make a setlist works out how many songs fit in 30 to 90 minutes.
Wedding processional
You don’t need the whole song, only the right section at the right moment. Time the walk at the rehearsal, then convert: in 4/4, bars = seconds × BPM ÷ 240. Say the walk takes 75 seconds and the song is a ballad at 72 BPM: 75 × 72 ÷ 240 = 22.5 bars. With the ballad in map 2 below, play the intro (4 bars), jump to the bridge (8), then the last chorus (8) and the outro (4): 24 bars, exactly 80 seconds, with a few seconds to spare. The chorus lands as the couple reaches the front. Give the musicians or the DJ the entry point and a fade point, and always start on a section boundary.
Auditions
Auditions ask for a cut, not a song. Musical theater calls often ask for 16 or 32 bars; Princeton University Players, for example, describes 16 bars as around 30–45 seconds and 32 bars as around 75–90 seconds. Check your cut with the formula: 16 bars of a 72 BPM ballad last 53.3 seconds, while 16 bars at 120 BPM last 32. If a slow song runs long, pick a faster section or fewer bars. A label pitch is different: send full songs, but make the first 30 seconds count, as explained in how to send a demo to a record label.
How long should an intro be?
Short. In most songs 2 to 4 bars is enough, about 5 to 10 seconds at 100 BPM. The intro sets the key, the tempo and the mood, may preview the hook, and then gets out of the way. Many pop songs open with the voice or with the chorus itself.
A quick test: if the voice hasn’t come in by 0:15, ask what the intro is doing. Good answers exist. A riff can be the hook. Dance music often uses long intros so DJs can mix; the planner’s EDM form has a 16-bar intro, 31 seconds at 124 BPM. And live, a longer intro gives the room time to recognize the song.
When a long song works
Length works when something keeps changing: a story that moves forward in every verse, an arrangement that grows each section, a shape with several parts. “Bohemian Rhapsody” runs almost six minutes and “Hey Jude” over seven because each part brings something new. What doesn’t work is repetition without development: a third verse that repeats the first two, a double chorus that adds nothing. Test it: play the recording and at every minute say what is new. If nothing is, cut.
Three song maps, timed with the formula
These are invented songs. The start times come from the formula, the same one the planner uses.
Map 1: “Porch Light”, a pop single at 120 BPM
One bar lasts 240 ÷ 120 = 2 seconds.
| Section | Bars | Starts at |
|---|---|---|
| Intro | 4 | 0:00 |
| Verse 1 | 8 | 0:08 |
| Pre-chorus | 4 | 0:24 |
| Chorus | 8 | 0:32 |
| Post-chorus | 4 | 0:48 |
| Verse 2 | 8 | 0:56 |
| Pre-chorus | 4 | 1:12 |
| Chorus | 8 | 1:20 |
| Post-chorus | 4 | 1:36 |
| Bridge | 8 | 1:44 |
| Chorus ×2 | 16 | 2:00 |
| Outro | 4 | 2:32 |
Total: 80 × 4 × 60 ÷ 120 = 160 seconds, 2:40. The voice enters at 0:08 and the chorus at 0:32, well before a listener decides to skip.
Map 2: “Kitchen Window”, a ballad at 72 BPM
One bar lasts 240 ÷ 72 = 3.33 seconds. The first draft had two verses before the chorus: Intro 4, Verse 8, Verse 8, Chorus 8, Verse 8, Chorus 8, Bridge 8, Chorus 8, Outro 4. That is 64 bars, 64 × 240 ÷ 72 = 213.3 seconds (3:33), but the first chorus only arrived at 1:07. Merging the best lines of the first two verses into one fixes it:
| Section | Bars | Starts at |
|---|---|---|
| Intro | 4 | 0:00 |
| Verse 1 | 8 | 0:13 |
| Chorus | 8 | 0:40 |
| Verse 2 | 8 | 1:07 |
| Chorus | 8 | 1:33 |
| Bridge | 8 | 2:00 |
| Chorus | 8 | 2:27 |
| Outro | 4 | 2:53 |
Total: 56 × 240 ÷ 72 = 186.7 seconds, 3:07. The chorus now arrives at 0:40.
Map 3: “Tailgate Summer”, a band song at 140 BPM
One bar lasts 240 ÷ 140 = 1.71 seconds.
| Section | Bars | Starts at |
|---|---|---|
| Intro | 8 | 0:00 |
| Verse 1 | 16 | 0:14 |
| Chorus | 8 | 0:41 |
| Verse 2 | 16 | 0:55 |
| Chorus | 8 | 1:22 |
| Solo | 16 | 1:36 |
| Bridge | 8 | 2:03 |
| Chorus ×2 | 16 | 2:17 |
| Outro | 8 | 2:45 |
Total: 104 × 240 ÷ 140 = 178.3 seconds, 2:58. It has more bars than map 1 and still runs under three minutes, because the tempo is faster. For a radio edit, cut the intro to 4 bars and the solo to 8: 92 bars, 157.7 seconds, 2:38.
To rebuild any of these, load “Pop: verse, pre-chorus, chorus, bridge” in the planner, edit the rows and bars, set the tempo and calculate.
Where Zoundroom fits: the timed map next to each version
Timing a song happens between versions: the demo, the shorter edit, the live arrangement with the long intro. In Zoundroom each song is a project that keeps those recordings, the lyric and your notes together. Paste the section map from the planner into a note with the bars, tempo and start times, then record a take inside that note; the audio lands at the cursor, next to the map. Import the radio edit you exported from your DAW into the same project, beside the full version, so you can compare them.
If you write with someone, invite them to the project. On Pro and Band they can leave comments at an exact second of a recording, such as “the chorus should land by 0:40”. Zoundroom does not edit audio: make the cut in GarageBand or your DAW and keep the result in the project.
Frequently asked questions
What is the average length of a song?
About three minutes for songs popular on streaming: Chartmetric put the average Spotify charting song at around 3:00 in 2024. Top 10 hits on the Billboard Hot 100 averaged 3:40 that year. Most pop songs fall between 2:30 and 3:30.
Is a 2-minute song too short?
No. A stream counts after 30 seconds whatever the length, and plenty of punk, rap and pop songs run about two minutes. If the song says everything in two minutes, a verse added only to reach three makes it weaker. Just make sure the chorus comes back at least twice.
How long is a radio edit?
There is no fixed standard. Radio edits usually bring a song to around 3:00–3:40, close to current chart averages, by shortening the intro, removing a solo or a repeated section and replacing the fade with an ending. Ask the station or promoter if they have guidelines.
How many bars is a verse?
Usually 8 or 16 bars in 4/4; rap verses are often 16. At 100 BPM, 8 bars last 19.2 seconds and 16 bars 38.4. In slow songs, 8-bar verses keep the first chorus from arriving too late.
