Calculating your total set length is straightforward once you know the Set List Duration formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the Set List Duration Calculator.
What is Set List Duration?
The Set List Duration calculation tells you your total set length from a few simple inputs. The figure you are solving for here is the total set length.
The Set List Duration formula
The core formula is:
Total set length = Number of songs × Average song length + (Number of songs - 1) × Gap between Number of songs ÷ 60Here is what each input means:
- Number of songs — a number. Example: 15.
- Average song length — a value measured in minutes. Example: 4 minutes.
- Gap between songs — a value measured in seconds. Example: 30 seconds.
How to calculate it step by step
- Write down the number of songs (for example, 15).
- Write down the average song length (for example, 4 minutes).
- Write down the gap between songs (for example, 30 seconds).
- Apply the formula above to get your total set length.
- Double-check the result with the Set List Duration Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Number of songs | 15 |
| Average song length | 4 minutes |
| Gap between songs | 30 seconds |
| Total set length | 67.0 |
With number of songs of 15, average song length of 4 minutes and gap between songs of 30 seconds, the total set length works out to 67.0.
Example 2
With number of songs of 30, average song length of 4 minutes and gap between songs of 30 seconds, the total set length works out to 134.5.
| Result | Value |
|---|---|
| Total set length | 134.5 |
Example 3
With number of songs of 7.5, average song length of 4 minutes and gap between songs of 30 seconds, the total set length works out to 33.3.
| Result | Value |
|---|---|
| Total set length | 33.3 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
