Mesh net overlap waste
Estimate how many light nets you need when you overlap edges for a seamless look, and how much coverage that overlap “wastes.”
effective_net_ft² = net_H × net_W × (1 − overlap% ÷ 100) · nets = ceil(cover_ft² ÷ effective_net_ft²)
When to use
Reach for the mesh net overlap waste calculator when a decorating decision depends on measurements you already have. You will enter coverage height (feet), coverage width (feet), one net height (feet), and one net width (feet).
Estimate how many light nets you need when you overlap edges for a seamless look, and how much coverage that overlap “wastes. Compare the panel result to the worked example, then adjust for spare strands, wind, or oddly shaped eaves.
Do not treat the output as an electrical-code stamp, install quote, or substitute for ladder safety and outdoor-rated gear.
10–20% overlap hides seams on hedges and lattice.
Worked example
Using the form defaults (Coverage height (feet) = 4, Coverage width (feet) = 12), walk the formula: effective_net_ft² = net_H × net_W × (1 − overlap% ÷ 100) · nets = ceil(cover_ft² ÷ effective_net_ft²).
A typical ceil(quantity ÷ size) path lands near 3 before spare percent — confirm against the Calculate result with the same inputs.
If your hand math disagrees, check units (inches vs feet) first.
Limits / assumptions
Assumptions: inputs match the hints (measured eaves, nameplate watts, package strand length, and so on). Terms not named in the formula are not secretly included.
Limits: outdoor weather, GFCI trips, and real stock sizes vary. Prefer outdoor-rated cords and clips; ladder and roof work need their own safety practices.
Responsibility: confirm safety-critical electrical and height decisions with manuals and, when needed, a qualified professional. PWC Lights does not stamp displays.
FAQ
Different from bush net count?
Bush net count is a simple area ratio. This page shrinks each net’s useful area by your overlap percent.
Zero overlap?
Set overlap to 0 for edge-to-edge planning (may show seams).
Tall shrubs?
Measure the face you actually wrap; multi-face wraps: run once per face or sum areas.
Irregular beds?
Add a spare net — ceil math under-orders odd shapes.
