Christmas Curtain Lights: How to Choose Them for Windows, Indoors and Outdoors
How to choose Christmas curtain lights for windows, indoors and outdoors: plain vs. animated curtains, size, LED count, IP rating, power and hanging tips.

Key takeaways
- Pick an addressable (pixel) curtain if you want pictures and text; a plain curtain if you only want a glow.
- Match the curtain size to the window or railing width so the strands hang flat.
- IP44 is fine under a roof; choose IP65 or higher for spots that get direct rain.
Christmas curtain lights are one of the easiest ways to make a window or balcony look decorated from the street: one horizontal wire with many thin strands hanging down, each strand carrying small LEDs. Hang the top wire, let the strands drop, and a whole surface lights up.
This guide covers what actually matters when you buy a set, whether it is for a window indoors, an outdoor balcony railing, or a patio door.
Plain curtains vs. animated (pixel) curtains
There are two very different products sold under the same name:
| Type | What it does | Best for |
|---|---|---|
| Plain curtain lights | Every LED shows the same color (often warm white), with a few flashing modes | Soft background glow, bedrooms, photo backdrops |
| Animated / pixel curtain lights | Each LED is individually addressable, so the curtain can show pictures, text and animations | Windows and balconies you want people to notice from the street |
If you want a Santa, a snowman or a "Merry Christmas" message on your window, you need the individually addressable kind (see our guide to animated Christmas lights). The listing will usually mention an app, "pixel", "programmable" or "DIY pattern".
Size and LED count
The two numbers to compare are width × height and total LEDs.
- A 2 × 2 m (about 6.5 × 6.5 ft) curtain covers a standard window or a short balcony section.
- A 3 × 3 m (about 10 × 10 ft) curtain covers a patio door or a wider railing.
- For animated curtains, more LEDs per square meter means a sharper picture. With the same number of LEDs, a smaller curtain looks more detailed and a larger one looks bigger but blockier from close up. From the street, both read well.
Measure the width you want to cover first. Curtain lights look best hanging flat, not bunched up, so pick the size closest to your window or railing rather than the biggest one.
Indoor vs. outdoor
Christmas curtain lights for windows can live indoors, hanging behind the glass and facing out. That is the safest setup and the picture is still clearly visible from outside at night.
For outdoor use, check the water rating:
- IP44 means splash resistant. Fine for a covered balcony or porch where rain does not hit the controller directly.
- IP65 and above handle direct rain.
Whatever the rating, keep the controller and the plug dry and off the ground.
Power: USB vs. mains
Many modern curtain lights run on 5 V USB. A USB set works the same in the US, the UK and the EU: only the wall adapter differs, so you avoid voltage and plug-type issues entirely. That is convenient indoors (any phone charger works) and very safe, but check whether a USB power adapter is included. Some sets ship with only the USB cable. Mains-powered sets are usually brighter and longer, but need an outdoor-rated socket when used outside.
How to hang curtain lights on a window
For more window ideas, see indoor Christmas window lights.
- Clip the top wire to the curtain rail, or use clear adhesive hooks along the top of the window frame.
- Let the strands drop straight. Do not stretch them, or the picture on an animated curtain will distort.
- Push the lights close to the glass. The closer they are, the less reflection you get inside the room.
- Hide the controller on the window sill and run the cable to a socket.
Buying checklist for Christmas curtain lights
Before you order, check these points on the listing:
- Width and height match the window, door or railing you want to cover.
- LED type: plain (one color at a time) or addressable pixels (pictures and text).
- Water rating: IP44 for covered spots, IP65 or higher for direct rain.
- Power: USB or mains, and whether the plug or adapter you need is in the box.
- Control: remote, app, or both, and whether the app has a timer.
- Cable length from the controller to the nearest socket.
- Returns and warranty, in case the size turns out wrong.
Common mistakes to avoid
- Buying the biggest size. A curtain that is too wide bunches up and the picture distorts.
- Hanging it far from the glass. You mostly light your own room and get reflections.
- Forgetting the adapter. Many USB sets ship with a cable only.
- Leaving the controller in the rain. The strands may be splash resistant while the controller box is not.
Storing curtain lights after Christmas
Lay the curtain flat, fold the strands together in one direction, and roll the bundle around a piece of cardboard before it goes back into the box. Keep the controller and remote in a separate bag. Stored this way, the strands do not tangle and the set is ready to hang again next year.
Our pick for an animated curtain
We are affiliated with Lumalyn, so take this with that in mind. The Lumalyn Smart Animated Balcony Lights are a 400-LED pixel curtain in 2 × 2 m or 3 × 3 m. They are controlled from a phone app or the included remote, sync to music, and are rated IP44 for sheltered outdoor spots. They are USB powered, and the set ships without a wall adapter, so plan to use one you already own.
If you only want a soft warm-white glow, a plain curtain from any hardware store is cheaper and will do the job.
Frequently asked questions
Can I use indoor curtain lights in a window facing outside?
Yes. Hanging curtain lights inside, close to the glass, is the safest way to decorate a window and they stay clearly visible from the street at night.
What does IP44 mean for Christmas lights?
IP44 means the lights are protected against splashing water from any direction. They suit covered balconies and porches, but not places where rain falls on them directly.
How many LEDs do I need for a curtain that shows pictures?
A grid of around 400 individually controlled LEDs is enough for recognizable holiday pictures and short words when seen from across the street.
