Calculate pond surface area, pond acres, water volume, gallons, liner size, excavation volume, pond perimeter, edging, aquatic plant count, pump flow, and estimated pond project cost.
Rectangular pond mode:
The calculator multiplies pond length by width to estimate surface area, then uses average depth to estimate volume and gallons.
Oval pond mode:
The calculator uses an ellipse formula to estimate pond surface area and an approximate oval perimeter.
Circular pond mode:
The calculator uses diameter to estimate pond surface area, perimeter, volume, gallons, liner area, and pump flow.
Known area mode:
The calculator starts from your known pond surface area and estimates water volume, gallons, plants, liner, edging, and cost.
A pond area calculator helps estimate backyard pond size, garden pond surface area, koi pond volume, farm pond acreage, liner size, water gallons, edging, plants, and pump flow.
It can help calculate pond square footage, acres, cubic feet, cubic yards, gallons, acre-feet, liner area, excavation volume, stone edging, aquatic plants, pump gallons per hour, and estimated cost.
Your result shows pond surface area, acres, perimeter, average depth, pond volume, gallons, acre-feet, liner dimensions, liner area, excavation volume, edging length, aquatic plant count, suggested pump flow, and estimated cost.
For a rectangular pond, multiply length by width. For a circular pond, use π times radius squared. For an oval pond, use π times half the length times half the width.
Multiply pond surface area by average depth to get cubic feet, then multiply cubic feet by 7.48052 to estimate gallons.
Add twice the maximum depth and twice the overlap allowance to both pond length and pond width. Then multiply liner length by liner width.
A simple estimate is pond gallons times the desired turnovers per hour. For example, one turnover per hour means a pump flow close to the pond gallon volume per hour.
No. It is an estimate. Actual pond area, volume, liner size, and gallons vary by irregular shapes, side slopes, shelves, depth changes, rocks, plants, settling, and construction method.
