Deck Lighting Calculator
Calculate the number of lights needed for your deck, estimate costs, and plan the perfect outdoor lighting layout for safety and ambiance.
Step 1: Deck Dimensions
Measuring Your Deck
Measure the longest length and width of your deck area. For irregular shapes, break it down into rectangular sections and add them together.
Step 2: Lighting Details
Light Spacing Tips
For ambient lighting, space lights 6-8 feet apart. For safety lighting on steps, space lights 2-3 feet apart. Closer spacing creates brighter illumination.

Lighting Calculation Formula
Number of Lights = (Deck Perimeter / Spacing) + (Area / (Spacing² × 2))
For optimal deck lighting, calculate both perimeter lights for edges and area lights for surface illumination. Adjust spacing based on desired brightness.
