How to Use This Calculator

Enter the infinity edge length in feet — the total span of the vanishing edge.
Set the overflow depth in inches (the water sheet thickness over the edge; 3/8 inch is typical).
Enter the total pool volume in gallons for surge basin sizing.
Set wind exposure: 1 = sheltered courtyard, 2 = typical backyard, 3 = exposed hilltop or coastal.
Enter the edge drop height from the pool deck to the catch basin floor.
Review Design Flow Rate (GPM), Catch Basin Volume, and Edge Pump HP to specify equipment.
