Proper Sizing and Fit

Correct sizing ensures proper fit, adequate overhang, and effective protection. Improper sizing causes installation problems and reduced effectiveness.

In-Ground Pool Sizing:

• Measurement: Measure pool at widest points (length and width)
• Overhang: Add 3–4 feet to each dimension for proper overhang
• Example: 16×32 pool needs 20×36 cover minimum
• Safety Covers: Custom-measured by professional installer
• Standard Covers: Choose next size up if between sizes
• Irregular Shapes: Require custom covers or professional measurement

Above-Ground Pool Sizing:

• Round Pools: Cover diameter 3–4 feet larger than pool diameter
• Example: 24-foot pool needs 27–28 foot cover
• Oval Pools: Add 3–4 feet to length and width
• Overhang: Ensures cable can secure cover below pool wall
• Too Small: Won't reach below wall, inadequate protection
• Too Large: Excess material creates water pooling and stress
• Find: Properly sized mesh covers for above-ground pools

Shape Considerations:

• Rectangle: Standard size, widely available
• Oval: Common for above-ground, available in standard sizes
• Kidney: Requires custom cover
• Freeform: Requires custom cover and professional measurement
• L-Shape: Requires custom cover
• Lazy-L: Requires custom cover

Measurement Tips:

• Measure at widest points, not at waterline
• Include steps and benches in measurements
• Measure twice to verify accuracy
• Round up to next standard size if between sizes
• For custom covers, hire professional measurer
• Document measurements with photos and diagrams

Safety Features and Certification

Safety features prevent child and pet drowning. ASTM certification is essential for families with children or pets.

ASTM F1346-91 Certification:
