Swim Stroke Count + SWOLF Calculator
SWOLF = stroke count + seconds for one pool length. Lower = more efficient.

Step-by-step
- SWOLF = strokes + seconds = 16 + 22 = 38.
- Distance per stroke = 25 / 16 = 1.56 m.
- Strokes per 100m extrapolated = 16 × (100/25) = 64.0.
How to use this calculator
- Pick pool length you swam.
- Count strokes for one length (one arm hitting water = 1 stroke).
- Time the length in seconds.
- Sum = SWOLF; compare across sessions.
About this calculator
SWOLF (Swimming-Golf) = stroke count for one pool length + seconds for that length. Lower is better. Elites SWOLF in the high 20s to low 30s in 25m pool freestyle. Recreational adults often score 50-60. The two ways to lower SWOLF: take fewer strokes per length (improve glide / catch / pull) or swim faster — usually you have to do both. Distance per stroke (DPS) is a related metric; ~2.0 m/stroke is solid recreational, 2.4+ m/stroke is competitive.
Frequently asked
Watches use accelerometer pattern recognition. Bilateral breathing or unusual catch can confuse them. Manual count is gold standard.
