The short answer: Plan where the lights go, measure, test every strand on the ground, attach clips first, then set the lights into the clips. Start at the end nearest the outlet, use outdoor-rated lights and a GFCI outlet, and skip nails and staples. Pick the guide below for your surface.

Safety first. Use only lights and cords rated for outdoor use, plug them into a GFCI-protected outlet, keep ladders and light strands at least 10 feet from overhead power lines, and have a helper. Hire a licensed electrician for any wiring or new outlet. See our safety guide. This reminder is ours; the sourced details are on that page.

Step by step

Plan after dark. Public Storage suggests walking the area at night and noting where you want lights: rooflines, railings, windows, trees, fences and walkways. Sketch it or mark up a photo. This Old House also says to plan your outlet locations.
Measure. Measure each run, then add 10% for slack, corners and spares (the Christmas Light Emporium, a retailer). Our calculator adds this up for you.
Test every strand on the ground. Public Storage says to plug in each one, check for burned-out bulbs, damaged cords and loose connections, and sort strands into working, needs repair and indoor-only piles. Swap in LED strands where you can. See LED vs incandescent.
Clean and check the surface. This Old House says to clean gutters and look for loose or damaged sections before you start.
Clip, do not tape or nail. Public Storage says to attach clips to gutters, shingles, trim or siding first, then set the lights into them. It says tape can trap moisture and fail, and that staples, nails and screws that pierce cords should be avoided. See no-nails options.
Start near the power. This Old House says to start at the end nearest the power source and make sure the plug reaches an outlet. Hook the first strand into the first clip and work along the line.
Join strands carefully. Only connect as many as the box allows. This Old House says to protect connections with weatherproof covers, and Public Storage says to hang strands with the female plug facing down so water does not collect.
Route the cords. Keep cords straight and out of walkways, and check for standing water and moving doors before you power on (Public Storage).
Add a timer. Illinois Extension says to turn lights off before you leave home or go to sleep, or have them timed to do so.
Walk the line. This Old House's troubleshooting tips: if lights sag or fall, add clips or tighten them, and use zip ties in windy areas. Check that plugs are fully seated and protected from moisture.

Need clips or a hanging pole?

Clips made for the job are gentler on your gutters and cords than nails or staples. Match the clip to your gutter, shingle or trim.

Common questions

What is the easiest way to hang Christmas lights?

Use clips made for your surface and set the lights into them. Public Storage and This Old House both describe clips as the better choice over tape, nails and staples. A light-hanging pole can let you clip lights from the ground (This Old House).

Where do I start when hanging Christmas lights?

At the end nearest the power source, so the plug reaches an outlet (This Old House). Plan the whole layout first, and test every strand on the ground before you hang it (Public Storage).

How many clips do I need?

This Old House says roughly one gutter clip for every 8 inches of gutter. Check the package of the clips you buy, because spacing can vary.

Should the lights be on a timer?

Yes, if you will not be there to turn them off. Illinois Extension and South Carolina's fire safety program both say to turn lights off before sleeping or leaving home, or use a timer.
