Our Mission
At Swimming Calculators, our mission is to empower swimmers—from first-timers to elite competitors—to reach their full potential. We provide accurate, intuitive tools that simplify calculations for pace, distance, calories, stroke efficiency, and performance analysis. With data-driven insights, swimmers can track improvement, optimize training, and take control of their progress with confidence.
What We Focus On
| Area | Description |
|---|---|
| Performance Tracking | Monitor pace, distance, stroke efficiency, and improvement trends. |
| Training Optimization | Use calculators to fine-tune workouts, intensity zones, and goals. |
| Smart Education | Clear definitions, tooltips, and benchmarks to help swimmers learn faster. |

Swimming Standards & Benchmarks
Official and widely-used standards to power accurate calculations, better training guidance, and clearer user education.
🏊 Pool Standards (FINA-compliant)
Include these pool sizes in conversions and calculators:
| Standard | Length | Common Code |
|---|---|---|
| Short Course (meters) | 25 m | SCM |
| Short Course (yards) | 25 yd | SCY |
| Long Course (meters) | 50 m | LCM |
Optional niche pool lengths
- 33⅓ meters — used in some training pools
- 20 meters — short hotel/training pool
- 15 meters — small therapy/training pool
⏱ Pace Standards & Formats
Common pace units your calculator should support:
- Pace per 25 m / 25 yd / 50 m
- Pace per 100 m / 100 yd (most universal)
- Pace per 400 m, 500 yd, 1500 m / 1650 yd, 1 km
🌊 Stroke Types
Include stroke-specific inputs and formulas:
- Freestyle (Front Crawl)
- Backstroke
- Breaststroke
- Butterfly
- Individual Medley (IM)
🎯 Age Group Categories
🎯 Age Group Guidelines
Age groups are used to categorize swimmers by development, competitive level, and training focus. They help coaches set realistic expectations and allow calculators to adjust pacing, intensity, and benchmarks.
🔥 Training Zones & Intensity
