How many feet of Christmas lights do I need for my house?

Measure the rooflines you want lit (front gutters, gables, peaks) and add about 30% for corners, drops to the outlet and spares. Most single-family homes land between 100 and 250 feet along the front.

The quick way

In Curbli, take a photo of your house and drag along the roofline; it measures the length (more accurate if you enter your house width) and adds the extra 30% for you. You can add the sides and back too.

By hand

  • Measure each roof edge at ground level along the house, add the slope lengths of gables, then add 30%.
  • For C9 bulbs, buy strands in matching lengths with spare bulbs.

What it costs installed

Seasonal (take-down) roofline lights installed by a pro: from $300 for a typical home. Permanent lights: about $990–$1,780 for 150 ft.

Questions

Why add 30%?

Corners, drops down to the outlet and a few spare bulbs or clips always take more than the straight roofline length.

What spacing should C9 bulbs have?

About 12 inches is the classic look for rooflines; closer spacing looks brighter.
