Christmas Tree Lights Calculator
A sparse tree looks sad; an over-lit tree is a fire hazard. This tool applies the 'Royal Statistical Society' formula (yes, they actually analyzed this) to help you achieve the perfect glow.
The Golden Ratio for Trees
According to mathematics from Sheffield University, the ideal number of lights is calculated by: Tree Height (cm) * Pi.
- Standard Rule: You need approximately 170 lights per meter of tree height for a 'warm' look, or 300+ for a 'brilliant' display.
- Ornaments: The recommended number of decorations is
(Tree Height in cm) / 2.
Professional Decorating Tip
Always wrap your lights from bottom to top, weaving them 'in and out' of the branches deeper toward the trunk to create depth. This uses roughly 15% more lights but results in a significantly more premium institutional-grade appearance.
