How to Hang Outdoor String Lights

After hanging string lights above our gravel fire pit area, I can vouch for how simple and transformative this DIY project is. String lights are an easy, affordable way to turn a backyard, patio, or seating area into a cozy extension of your home.

The warm glow of glass-bulb string lights adds instant ambiance and makes outdoor spaces feel inviting. Below is a clear, step-by-step guide for planning, purchasing, and installing outdoor string lights—plus common questions and safety tips to help you get the best result.

How to hang outdoor string lights

Our backyard makeover began when we removed a trampoline and considered installing sod. Instead, the open circle inspired a gravel fire pit area, and adding planters and string lights finished the space. The images below show the transformation from bare lawn to a warm, usable outdoor living spot.

Even after the hardscaping and planters were in place, the string lights elevated the area from pleasant to magical. If you’re ready to do something similar, follow these three basic steps to hang outdoor string lights that suit your space and style.

Step 1: Measure where you plan to hang your outdoor lights

Begin with a rough sketch of the area to map out where the lights will start, end, and where intermediate anchor points will be. Identify the nearest GFCI-protected outdoor outlet so you can account for the plug location when planning cable length.

Using a tape measure, record the distance between each planned anchor point, measuring from the first to the second, then from the second to the third, and so on. Add extra length for slack and to reach the power source; you may need a weather-resistant extension cord depending on outlet location and how much cord remains at the end of the strand.

If you don’t have trees or existing posts to secure lights, consider purchasing or building a heavy-base string light post to serve as an anchor.

Step 2: Choose and buy the light strands and hardware

Cafe lights (also called bistro or string lights) come in many styles, bulb shapes, and lengths. Pick outdoor-rated strands and, if using LED bulbs, make sure the bulbs and cords are rated for exterior use. If you need to connect multiple strands, follow the manufacturer’s specified maximum connection limit—do not exceed it.

For our installation we needed about 75 feet of lights and used a 50-foot strand and a 25-foot strand from the same manufacturer to keep voltage and connectors consistent. If you must join strands, use weatherproof connection covers to protect connections from moisture.

Buy a string light hanging kit. A quality kit usually includes guide wire, cable clamps, zip ties, cup hooks, turnbuckles, brackets, carabiners, and mounting screws. The guide wire reduces sway and sag, and turnbuckles let you tighten the line for a neat, taught look. This kit approach makes the installation far more durable and storm-resistant than hanging lights without support.

Also pick up an outdoor smart plug if you want to dim lights or control them by phone or voice assistant. Many smart plugs work with Alexa, Google Assistant, and smart home hubs and make it simple to schedule or automate your lights.

Step 3: Hang your outdoor lights with a helper

This is an easy DIY but much safer and faster with two people. One person can hold the lights or stand as a spotter while the other works on a ladder. Start by installing brackets at your start, end, and any intermediate anchor points. Drill pilot holes appropriate for your bracket screws and the surface you’re attaching to.

Attach a turnbuckle to one end of the guide wire, secure the loop with a screw clamp, and hook it onto the first bracket. Run the guide wire to the next anchor points and finish at the ending bracket where you’ll secure and clamp the loop and add a carabiner. Return to the start turnbuckle and tighten until the guide wire is as taut as you want.

Once the guide wire is secure, attach the string lights to the wire using zip ties, spacing ties so each bulb sits evenly and the strand follows the guide wire line. Use enough ties so wind won’t easily displace bulbs, but avoid overtightening that could damage the cord.

FAQs About Hanging Outdoor String Lights

String lights are versatile and work in countless outdoor setups. Below are answers to common questions that often come up during planning and installation.

How far can you string lights without support?

For short distances you may get away without a guide wire, but for spans over 100 feet a guide-wire system is essential. Guide wires prevent sagging, reduce wind damage, and keep lights from falling—saving time and frustration later.

If you lack tall anchors like trees, consider freestanding light posts with heavy bases or construct a DIY post to secure lights.

How low should string lights hang?

Aim for at least 8 to 10 feet overhead to allow comfortable clearance underneath. If you’re using a guide wire, hang the wire about a foot higher than your intended lowest point to allow for a little natural slack.

Can I hang string lights near a pool or hot tub?

For safety, keep string lights at least 10 feet above water features such as pools or hot tubs. Use lights rated for wet locations (look for IP65 or higher) when installing near water to prevent electrical hazards.

Can you use nails to hang string lights?

Nails can work for high, out-of-the-way placements like along a fence or the interior of a pergola. However, screw-in cup hooks or screw hooks are generally better: they hold cords more securely in wind and are safer for repeated use. For the strongest hold, use safety cup hooks that include a small closing clip.
