Pond Dimensions (in feet)
Measure your pond at its longest, widest, and deepest points. For irregular ponds use your best average measurements.
💡 Pro tip: These calculations assume flat-bottomed ponds. Most garden ponds have sloped sides, so your actual volume is typically 20-30% less than the calculated figure. When in doubt, stock conservatively!
