Pond Volume Calculator: Global Water Precision for Healthy Ecosystems

From koi ponds to natural swimming pools, our pond volume calculator delivers exact water volume in gallons and liters — trusted by pond builders and hobbyists worldwide.

"Still waters run deep."

How the Pond Volume Calculator Works

Using 2025 global standards, the pond volume calculator accounts for:

  • Shape geometry (rect, circle, oval)
  • Sloped sides and variable depth
  • Liner sizing with overlap
  • Pump flow rate (GPH)
  • Fish stocking density
  • Chemical treatment dosage
Volume (gal) = Area × Avg Depth × 7.48
Liner = (Length + 2×Overlap) × (Width + 2×Overlap)

Standard Pond Volume Guidelines (2025)

Pond Type Min Depth Max Fish Pump Turnover
Koi Pond 3–4 ft 1 per 250 gal 1 hour
Goldfish Pond 2–3 ft 1 per 50 gal 2 hours
Water Garden 1.5–2 ft Light 4 hours

Why Use This Pond Volume Calculator?

  • Dual Units — Gallons & Liters
  • All Shapes — Including irregular
  • Liner Sizing — With overlap
  • Fish Safe — Stocking limits
  • Pump Match — Flow rate calculator

Pond Volume Calculator Pro Tips

  1. Measure at water line — Not bank edge
  2. Use 2 ft overlap — For secure liner
  3. Never overstock — 1 koi per 250 gal
  4. Turn over every 2 hrs — Healthy water
  5. Add 10% buffer — For evaporation
