Thankfully, with our help, you won't have to learn those lessons the hard way. We hope to save you from all that frustration by showing you exactly how to do it right from the start ❤️💙💛
So, get ready to be the most beautiful home on the block this Christmas, as we answer the most-asked question: how to hang outdoor Christmas lights?
Plan Your Outdoor Christmas Light Layout First
Before you climb the ladder or plug in a single strand, take a few minutes to plan your display. As boring as it sounds, it’s an essential part of Christmas decor that will save you A LOT of time, frustration, and even money.
Start with a quick walk around your home and decide which areas you want to highlight. Some people prefer a simple roofline outline, while others like to include windows, doorways, trees, shrubs, pathways, or even fences. It's also worth thinking about your power source before you begin. Check where your outdoor outlets are located and plan how your extension cords will reach each section without creating a tangled mess.
Tools and Supplies You’ll Need
Before you start, it helps to gather everything in one place. This makes the installation process smoother and keeps you from climbing up and down the ladder more than necessary.
You may need:
-
Outdoor-rated Christmas lights
-
Outdoor-rated extension cords
-
Gutter clips, shingle clips, adhesive hooks, or suction-cup clips
-
A tape measure
-
A stable ladder
-
Outdoor-rated zip ties or reusable twist ties
-
Weatherproof cord covers
-
An outdoor timer or smart plug
-
Work gloves
-
The original packaging or instruction manual for your lights
A little preparation goes a long way here. Once your layout, lights, clips, cords, and power source are planned, the actual installation becomes much easier.
Quick Steps: How to Hang Outdoor Christmas Lights
-
Plan your outdoor Christmas light layout.
-
Measure your roofline, windows, doors, trees, railings, fences, and yard areas.
-
Test every light strand on the ground before installation.
-
Choose outdoor-rated lights, clips, hooks, extension cords, and timers.
-
Start hanging lights near the outdoor power source.
-
Attach the lights with clips instead of nails, staples, or screws.
-
Keep the strands slightly loose instead of pulling them too tightly.
-
Keep cords away from walkways, driveways, puddles, and snow buildup.
-
Plug the display into a GFCI-protected outdoor outlet whenever possible.
-
Turn the lights on and inspect the full display before leaving them running.
Measure the Roofline, Windows, Doors, and Yard Areas
Please do not attempt to “guess” how many lights you’ll need. It might seem quicker, but it often leads to multiple trips back to the store, or a nightmare situation where you discover you're a few feet short when you're almost finished. Plus, if you’ve ordered from a collection online, like the one available at Fly Achilles, that means another round of delivery days (we’re fast, but even 3 days is too long when you’re eager to complete the project, right?).
So get to work before the last-minute panic gets to you 😆 Grab a tape measure and note the length of every area you plan to decorate, including your roofline, windows, doors, railings, fences, bushes, and trees. If you're wrapping tree trunks or columns, measure both the height and the circumference so you can estimate how many strands you'll need. You’d also want to add a little extra length for corners, peaks, and the distance to your nearest power outlet. Once you've written everything down, compare your measurements with the length listed on each light set before buying.
Top Tip- If you want to avoid an additional trip up the ladder (and if your roofline is completely flat), another way to estimate the width/length of the area you want to light up is to measure your house’s width at its base. Though not precise to the inch, it gives you a good idea of how many feet or strands of lights are required.
Choose the Right Outdoor Christmas Lights

When buying lights to decorate the exterior of your home, look for options marked specifically for outdoor (or indoor/outdoor) use. They're built to handle rain, snow, and changing temperatures, which means they’ll last the entire holiday season (and maybe even the next 😉). Your best bet would be to splurge on LED Christmas Lights, because they’re incredibly durable and energy-efficient. Even better if they’re labeled UL (an indication that the product has been tested for safety by Underwriters Laboratories).
Also, don’t forget to think about the look you're going for. Mini lights are great for wrapping trees and shrubs, C7 and C9 bulbs create that classic roofline look, while net lights make decorating bushes easy. If you want to add a bit more personality, icicle lights work beautifully along eaves, and pathway lights can brighten up walkways & driveways.
Use the Right Clips, Hooks, and Fasteners
It might be tempting to reach for nails, staples, or whatever you already have lying around, but they'll actually end up damaging your home and even your light strands. For an easy time hanging (and taking down) your outdoor Christmas lights, do yourself a favor and invest in a few sets of light clips.
Remember, different surfaces call for different fasteners…
-
Gutter clips work well along the roof edges
-
Shingle clips are ideal for sloped roofs
-
Adhesive hooks can be useful for smooth surfaces around doors and windows
Top Tip- Do not pull the strands too tightly when installing the lights. Leaving a little slack helps prevent unnecessary strain on the wires and reduces the likelihood that a bulb or connection will come loose.
How to Hang Christmas Lights on the Roofline
The roofline is usually the star of any outdoor Christmas display, but it's also the area where safety matters most. First things first, make sure your ladder is on stable, level ground, and avoid decorating in wet, icy, or windy conditions.
Now that the safety conditions are met, you can start hanging up the lights at the end closest to your outdoor power outlet and work your way across the roof. Attach the light strand using roof or gutter clips, spacing them every few feet to keep the lights neat and secure. If you're using C7 or C9 bulbs, many roof clips are designed to hold each bulb upright for a clean, professional-looking finish.
Again, we’d recommend not to stretch the lights too tightly, and if you need to connect multiple strands, be sure to stay within the manufacturer's recommended limit to avoid overloading the circuit. Also, plug your outdoor lights into a GFCI-protected outdoor outlet whenever possible, and only use lights and extension cords that are rated for outdoor use.
How to Hang Lights Around Windows and Doors
Hanging Christmas lights around windows and doors is best done using adhesive decorating clips or suction-cup clips. These methods ensure a clean outline and zero damage to your paint, wood, or glass.
Keep in mind:
-
Adhesive clips are best for door frames, brick, or siding.
-
Suction cup hooks are ideal for the perimeter of smooth windows or the glass itself.
-
Gutter hooks work best if your window sits directly below a roofline, as you can use these to anchor the top strand easily.
Now that you’ve understood the required equipment, all you have to do is give the door/window surfaces a quick wipe with rubbing alcohol. Then attach the clips, spacing each 3 inches apart.
Top Tip- Press and hold the clips or suction cups firmly against the surface for at least 30 seconds to lock in maximum suction. If using adhesive clips, wait at least one hour before attaching the lights to allow the adhesive to set.
Finally, snap or tuck the light strand into each clip, starting near an electrical outlet, of course.
How to Wrap Lights Around Columns, Railings, and Trees
The trick here is to keep the spacing consistent.
For columns and porch posts, begin at the bottom and work your way up (or vice versa) in an even spiral, securing the strand every few wraps using outdoor-rated zip ties. You can also go for the “No Wrap” strap method, where a set of straps wraps around the top and bottom, with built-in clips to hold your string lights securely in a straight vertical line or a candy-cane spiral.
As for railings, they’re much easier to decorate. Simply weave the lights around the rails or wrap them in a gentle spiral, and, again, secure them every few feet with reusable twist ties if needed.
Trees, however, require a more solid plan. When lighting the trunk, start at the base of the tree (ensuring your power source is plugged into an outlet/extension cord), and wind the light string around the trunk (a space of one hand width between each wrap is enough). Once you reach the first large branches, follow the main boughs out about 3 to 4 feet. Wrap the Christmas lights along the tops and bottoms of the branches to create three-dimensional depth.
Top Tip- Roll your light strands into a ball before you begin to make wrapping easier.
How to Hang Christmas Lights on the Roofline
The roofline is usually the star of any outdoor Christmas display, but it's also the area where safety matters most. First things first, make sure your ladder is on stable, level ground, and avoid decorating in wet, icy, or windy conditions.

Again, we’d recommend not to stretch the lights too tightly, and if you need to connect multiple strands, be sure to stay within the manufacturer's recommended limit to avoid overloading the circuit.
How to Hang Christmas Lights Around Windows and Doors
Hanging Christmas lights around windows and doors is best done using adhesive decorating clips or suction-cup clips. These methods ensure a clean outline and zero damage to your paint, wood, or glass.
Keep in mind:
-
Adhesive clips are best for door frames, brick, or sliding.
-
Suction cup hooks are ideal for the perimeter of smooth windows or the glass itself.
-
Gutter hooks work best if your window sits directly below a roofline, as you can use these to anchor the top strand easily.
Now that you’ve understood the required equipment, all you have to do is give the door/window surfaces a quick wipe with rubbing alcohol. Then attach the clips, spacing each 3 inches apart.
Top Tip- Press and hold the clips or suction cups firmly against the surface for at least 30 seconds to lock in maximum suction. If using adhesive clips, wait at least one hour before attaching the lights to allow the adhesive to set.
Finally, snap or tuck the light strand into each clip (starting near an electrical outlet, of course).
How to Light Bushes, Fences, and Walkways

Net lights are by far the quickest option to light up bushes. Simply drape them evenly over the shrub and adjust them until the lights are spread out properly. If you're using string lights, weave them gently through the branches instead of wrapping only around the outside.
Fences can be decorated in more than one way. You can, for example, run lights along the top rail for a clean outline, or weave them between the slats. Retrofitting your fence posts with solar or low-voltage post cap lights is also a fun idea. Outdoor-rated clips and reusable zip ties both will work perfectly to secure the strands neatly.
Walkways, too, can be covered in the holiday spirit. Path lights (such as lantern-style or modern bollards) are a popular favorite. Downlighting looks equally stunning, creating a moonlight glow as the spotlights mounted high up in nearby trees or architectural features highlight the pathway. If you're outlining the path with string lights, keep them low to the ground and away from areas where people might trip.
Outdoor Power, Extension Cord, and Timer Tips
Your Christmas lights are only as reliable as the power source behind them, so it's worth spending a few minutes getting this part right.
Always use extension cords that have been rated for outdoor use to make sure they can handle changing weather conditions and moisture. In case you need to connect multiple cords, keep the connection points off the ground and protect them with weatherproof covers to help keep rain and snow out.
It's also important not to overload a single outlet. Before connecting multiple light strands, check the manufacturer's recommendations for the maximum number that can be safely linked together. Also, double-check where your power source will be, then plan the route your extension cords will take accordingly.
Top Tip- Plug your display into an outdoor timer or smart plug. You can set your lights to turn on automatically at dusk and turn off later in the evening, so you won't have to remember to do it every day.
Safety Tips Before You Turn the Lights On
Nothing too complicated here. Just a few final checks…
-
Walk around your display to inspect each light strand for cracked bulbs, frayed wires, loose connections, or damaged sockets.
-
Ensure every clip, hook, & zip tie is secure, and while you're at it, double-check that extension cords aren't stretched across driveways, walkways, or anywhere people could trip over them.
-
Lastly, plug the lights in and watch the entire display for a minute or two. If you notice flickering, sections that don't light up, or bulbs that seem unusually hot, unplug the lights and find the cause before leaving them on.
Top Tip- Keep the packaging or instruction manual that came with your lights until the holidays are over, so if you need to troubleshoot a problem, you’ll have the information right on hand.
Common Mistakes to Avoid
Even with the best intentions, it's easy to make a few mistakes that can leave your Christmas display looking less than festive. Here’s what you shouldn’t do:
-
Skip the planning stage and jump to the buying stage.
-
Use indoor lights outdoors
-
Mount the lights with nails/staples/screws
-
Overload the outlets
-
Forget to test the lights first
-
Stretch the lights too tightly
-
Decorate in bad weather
-
Overreach from a ladder
-
Leave cords where someone could trip over them
How to Take Down and Store Christmas Lights
Don't call us crazy, but the end of Christmas is when we start thinking about next Christmas 😆 Kidding, we’re only talking about packing your lights the right way.
Resist the urge to strip it all off, and take the time to unplug all the lights and remove them gently, working in the reverse order that you installed them. If you find any damaged sections, set them aside for repair or replacement.
Off to the storage now. Rather than stuffing the lights into a storage box, wrap each strand neatly around a piece of cardboard, a plastic light reel, or a storage spool. Keep your clips, hooks, zip ties, and timers in the same box.
Then, before putting everything away, label the strands based on where they were used, such as Roofline, Front Door, Bushes, or Tree.
That’s it. You can now tuck it all into a cool, dry place.
FAQs
What is the least damaging way to display Christmas lights?
When talking about how to hang outdoor Christmas lights without causing damage, the best solution is to use plastic light clips. Adhesive hooks work, too.
How to hang outdoor Christmas lights on a wall?
You can use adhesive hooks (they’re removable) or attach the lights with hot glue.
How many feet of Christmas lights do I need?
The best way to know is to measure every area you plan to decorate, including the roofline, windows, doors, railings, fences, bushes, trees, and the distance to your nearest power outlet. It is also smart to add a little extra length for corners, peaks, and gaps between sections.
What clips should I use for gutters?
Gutter clips are usually the best choice for hanging Christmas lights along roof edges. They help hold the light strand in place without damaging the gutter or the wire. If you’re using C7 or C9 bulbs, look for clips that can hold each bulb upright for a cleaner roofline look.
Can I leave outdoor Christmas lights on overnight?
You can, but it is usually better to use an outdoor timer or smart plug. This allows your lights to turn on automatically at dusk and turn off later in the evening, which saves energy and helps reduce unnecessary wear on the lights.
How do I keep outdoor extension cords dry?
Use outdoor-rated extension cords and keep connection points off the ground whenever possible. If you need to connect multiple cords, protect the connection points with weatherproof covers and avoid placing cords in puddles, snow buildup, or areas where water collects.
Should Christmas lights face up or down on the roofline?
It depends on the look you want, but the most important thing is consistency. Many roof clips are designed to keep C7 or C9 bulbs upright for a clean, classic roofline display. Whichever direction you choose, keep the bulbs aligned the same way across the roofline for a more polished result.
