Tree strand count
Estimate mini-light strands for wrapping a tree from height and wrap density (feet of lights per foot of height).
Formula
total_light_feet = tree_height × wrap_density · strands = ceil(total_light_feet ÷ strand_length)
Sparse ~50–75, classic ~100, dense ~150–200+ for outdoor trees.
FAQ
What wrap density should I use?
Indoor trees often look full around 100 light-feet per height-foot; outdoor trunks/branches may need more for curb visibility.
Does trunk wrapping use the same math?
Roughly — measure the lighted height and pick a denser wrap if you spiral tightly.
Should strands be end-to-end?
Stay within the manufacturer’s max connections and outlet load; split feeds on large trees.
What about bush nets instead?
For shrubs, try the bush net count calculator instead of spiral wraps.
