🌊 Pool Size Calculator · Ultimate Volume & Dimension Tool
✔️ For optimal filtration, turnover pool water once every 8–10 hours.
✔️ USA residential pools average 15,000–30,000 gallons; in Europe 40–80 m³.
✔️ Always verify local safety codes: depth markings & anti-entrapment drains.
✔️ Model year ‘2024+’ often includes variable-speed pump compatibility; update your equipment accordingly.
*Comparative volume vs standard reference pools (global benchmarks)
1️⃣ Select your pool shape (Rectangle, Round, Oval, Kidney).
2️⃣ Enter dimensions: length, width, depth (or radius for round pools).
3️⃣ Choose measurement unit (Imperial = gallons, Metric = liters/m³).
4️⃣ Add custom Model Year (any year like 2024–2026+).
5️⃣ Press “Update Calculator & Graph” — results auto-refresh instantly (also on input change).
6️⃣ The advanced graph compares your pool volume to typical residential sizes in different regions. Great for planning chemicals, heating, pumps!
❓ Why does pool shape affect volume so much?
Different shapes have distinct surface areas. A kidney pool typically requires a reduction factor (~0.85) from rectangular area. The calculator uses industry-accepted coefficients for accurate water capacity, helping in chemical treatment & pump sizing.
❓ How is the pump runtime estimated?
Based on US Dept. of Energy guidelines: pool volume (gallons) / (filter flow rate assumption 45 GPM for average pump) and 1 daily turnover. For metric: liters/(170 L/min). Provides a baseline runtime for energy planning.
❓ Which countries use gallons vs liters?
USA predominantly uses gallons, while Canada, UK, Europe, Australia and most other regions use liters or cubic meters. Toggle between systems for automatic conversion and local relevance.
