Pond Liner Calculator
Calculate the perfect pond liner size for your water feature. Determine liner dimensions, overlaps, and material requirements based on pond shape, depth, and liner type.
Step 1: Pond Specifications
Understanding Liner Sizing
Pond liners need to be larger than the pond dimensions to account for depth, overlap, and anchoring. Typically add 2-3 feet to each dimension for proper installation.

About Liner Materials
EPDM rubber is the most durable (20+ year lifespan) and flexible. PVC is economical but less UV resistant. HDRPE is puncture-resistant and good for rocky soil. Always use underlayment to protect the liner.

Liner Calculation Breakdown
Liner Sizing Formula
Liner Length = Pond Length + (2 × Depth) + (2 × Overlap)
Liner Width = Pond Width + (2 × Depth) + (2 × Overlap)
For circular ponds, use diameter instead of length/width. Add extra material for freeform or irregular shapes (typically 10-15% more).
