How to Choose the Right String Light Size

Selecting the correct size makes decorating twice as effective with half the effort. Here are our recommendations for different scenarios.

10 ft+ (Commercial/Lobby)400 ft+800 lights+Professional installation, multi-circuit design

Calculation Formula

Formula: Tree height (ft) × Density Factor = Required feet

  • Minimalist style: Factor 8–10
  • Standard decoration: Factor 12–15
  • Luxurious effect: Factor 18–20

Example: 7 ft tree, standard decoration = 7 × 13 ≈ 90 ft
