This tool helps you calculate the number of Christmas lights needed to decorate your house.
How to Use the Christmas Light Calculator
To determine how many Christmas lights you need for your house, please fill in the following parameters:
- House Height: The total height of your house in feet.
- House Width: The total width of your house in feet.
- Roof Pitch: The pitch or slope of your roof in percentage.
- Total Eaves Length: The cumulative length of all eaves (edges of the roof) where lights are to be hung, in feet.
- Spacing between Lights: The desired spacing between each Christmas light on the string, in feet.
Explanation
The Christmas Light Calculator computes the total length of lights you would need based on the dimensions and specifications provided. It sums up the perimeter created by the house height, width, and the roof pitch. Then it adds the total eaves length. Finally, it divides the total length by the spacing between lights to give you the number of lights needed.
Limitations
Please note that this calculator provides an estimate. The actual number of lights required may vary based on house shape, additional decorations, and installation preferences.
