Pool Laps for Distance Calculator
Laps = ⌈target distance / pool length⌉. Convert any target distance to laps in any pool.

60
60 lengths of 25m.
- Target1500 m
- Target (meters)1,500.0 m
- Pool length25 m
- Lengths needed60.00 (round up: 60)
- Lap definition1 length = 1 lap
- Laps (round up)60
Step-by-step
- Target in m = 1,500.0.
- Lengths = 1,500.0 / 25 = 60.00.
- Laps = lengths × lap factor = 60.00, round up = 60.
How to use this calculator
- Enter target distance + unit.
- Pick pool length (US YMCAs are usually 25y; competitive 25m or 50m).
- Pick lap convention.
- Round up — don't end mid-pool.
About this calculator
A "lap" is ambiguous: in track and most casual swimming, one length = one lap; in lane swimming and competitive contexts, down-and-back = one lap. This calculator handles both. A 1500m target in a 25m pool: 60 lengths or 30 down-and-back laps. In a 25-yard pool: 65.6 lengths → round up to 66. Don't fret partial lengths — round up and finish at the wall.
Frequently asked
In open water, "lap" = one circuit of the buoy course. In pool sprints, "lap" = down-and-back = 50m in a 25m pool.
