Swim Pace Calculator
Calculate swim pace per 100 yards or meters from any distance and time.
Pace per 100
Reading swim pace
Swimmers typically pace by time per 100 yards or 100 meters rather than a full-distance average, since pool sets are usually built around 100s, 200s, and their multiples.
US pools are commonly yards (25 yd short course), while most international and Olympic pools are meters (25m or 50m). Make sure your distance unit matches the pool you swam in.
Where these numbers come from
The formulas and default values in this calculator are based on:
- Standard pace-per-100 convention used in competitive and masters swimming
These are planning estimates for training purposes. Check with a coach, trainer, or physician before starting a new program or maxing out.
Frequently asked questions
What's a good swim pace for a beginner?
Pace varies enormously by swimming background, but many adult beginners fall somewhere around 2:00 to 2:30 per 100 yards for freestyle.
Does stroke type change how this calculator works?
No, the pace math is stroke-agnostic. Just make sure your time and distance both reflect the stroke you're measuring.
Yards vs. meters — does it matter which I pick?
Yes, a 25-yard pool and a 25-meter pool are different distances (25m is about 8% longer), so picking the wrong unit will skew your pace.
