Calculate playlist length from the number of songs and the average song length (3.5 minutes by default), or find how many songs fill a target time.

Typical song ≈ 3.5 min (3:30); change it for your playlist. For 4 min 15 sec enter 4.25 min or 255 sec.

Daily listening time (optional)
Leave blank to omit the estimate; at most 24 hours/day.

Playlist Length Formula

The following two example problems outline the steps and information needed to calculate the Playlist Length.

PL = SL × S
  • Where PL is the Playlist Length (minutes)
  • SL is the average song length (min) 
  • S is the number of songs 

To calculate a playlist length, multiply the average song length by the number of songs.

How to Calculate Playlist Length?

The following example problems outline how to calculate Playlist Length.

Example Problem #1:

  1. First, determine the average song length (min).
    • The average song length (min) is given as 3.5.
  2. Next, determine the number of songs.
    • The number of songs is provided as 10.
  3. Finally, calculate the Playlist Length using the equation above: 

PL = SL * #S

The values provided above are inserted into the equation below and computed.

PL = 3.5 * 10 = 35 (minutes)


Example Problem #2: 

For this problem, the variables required are provided below:

average song length (min) = 3

number of songs = 20

Test your knowledge using the equation and check your answer with the calculator.

PL = SL * #S = ?
