These 20 Christmas window lighted decorations fit a 36 x 48-inch apartment window or a narrow 24-inch one, with battery setups from about $7 to $30. Every idea uses removable hooks, suction cups, a sill or a curtain rod, so no nails go into frames, paint or window seals.
Pick one light source, warm white, and let the window do the rest.

Key Takeaways
- A 36 x 48-inch window has about 14 feet of frame, so two 12-light battery strings cover it.
- Battery lights keep cords off the floor and work in windows with no outlet nearby.
- Warm white light looks best at night from the street and from the sofa.
- Keep flames and heat sources at least 12 inches from curtains, and use flameless candles on a sill.
- Test every strand before hanging it, then switch lights off when you leave or sleep.
Lights Around the Window Frame
The frame is the simplest place to start, because it is visible from the street and from inside.
1. A Two-String Outline on a Standard Window
A 36 x 48-inch window has about 14 feet of perimeter, and one 12-light battery string runs just under 7 feet. Two strings joined end to end outline it fully. IKEA’s LEDFYR was $6.99, is about 6 feet 11 inches long, and takes two AA batteries. It is indoor-only.
Cost: ~$14 · Renter-safe: Yes
2. A Single Swag Across the Top
On a narrow or small window, one string draped in two or three shallow loops along the top rail looks full without covering the glass. Attach it with a small adhesive hook at each end and one in the middle, with the loops about 6 inches deep. One string keeps the cost near $7.
Cost: ~$7-$12 · Renter-safe: Yes
3. Vertical Drops Like a Light Curtain
Hang four or five strands straight down from one rail or rod so they fall like icicles. Space them 6 to 8 inches apart and stop the bottoms an inch above the sill so they do not tangle. Plug-in curtain sets usually cost about $15-$30, an editorial estimate, and need an outlet near the window.
Cost: ~$15-$30 · Renter-safe: Yes
4. Lights Behind a Sheer Curtain
Tuck a string behind a white sheer panel and the bulbs blur into a soft glow instead of separate dots. This suits bedroom windows, where sharp points of light feel harsh at night. A battery LED string stays cool, so the fabric is not in contact with any heat.
Cost: ~$7 · Renter-safe: Yes
5. A Zigzag Across a Divided Window
If the window has a center bar or a grid, run a string back and forth between small clips on the frame, so the wire follows the panes. It reads as a deliberate pattern and uses a single string. Allow about one clip per 2 feet of wire, and check the package for weight limits and surfaces.
Cost: ~$7-$15 · Renter-safe: Yes
Lighted Windowsill Displays
A sill is a shelf with a view. Keep these low, so the light reaches the glass and not the curtain.
6. A Jar of String Lights
Coil a 12-light battery string into a clear 4-inch-tall jar, and the jar glows like a lantern. A 17-ounce KORKEN jar was $2.99 at IKEA, and the LEDFYR string $6.99. Hide the battery pack behind the jar or inside a nearby basket, and the jar can move to a shelf later.
Cost: ~$10 · Renter-safe: Yes
7. A Row of Rechargeable Tealights
Line up flameless tealights along the sill, spaced about 4 inches apart, with a mini tree or a sprig of greenery at one end. IKEA’s SKATGAS kit was $19.99 for four tealights, a charging tray and a USB cable. They run about 35 hours per charge and are indoor-only.
Cost: ~$20 · Renter-safe: Yes
8. A Mini Tree With a Tiny String
A 12-inch artificial tree wrapped in a short battery string fits on most sills and glows toward the street. Small trees cost about $10-$20, an editorial estimate. Place it at one end so it does not hide the glass, and keep the battery box behind the pot.
Cost: ~$17-$27 · Renter-safe: Yes
9. Paper Bag Luminaries on the Sill
Fill small paper bags with an inch of sand or rice, and set a flameless tealight in each. Cut a star or snowflake from the front before folding, and the light shines through the shape. A batch of five bags costs a few dollars, and the bags can be recycled in January.
Cost: ~$3-$5 · Renter-safe: Yes
10. A Candle Lantern on a Deep Sill
If the sill is at least 5 inches deep, a metal or glass lantern with a flameless pillar looks like a small hearth. A 3.5-inch battery pillar with a 3 or 6-hour timer was $5.99 at IKEA. A lantern runs about $10-$20, an editorial estimate, so add that to the total.
Cost: ~$16-$26 · Renter-safe: Yes
Glass and Hanging Lights
These hang in front of the glass, so they work on windows with no sill or with a radiator below.
11. Suction-Cup Light Silhouettes
Battery-powered stars, trees and snowflakes stick to glass with suction cups and need no wiring. Look for LED bulbs and a small battery box. Simple versions cost about $8-$15 per piece, an editorial estimate. Press them onto a clean, dry pane, and wipe the glass first.
Cost: ~$8-$15 · Renter-safe: Yes
12. A Paper Star Lantern With a Light Inside
Fold a paper star from white paper, or buy a ready-made one, and drop a battery light inside. Hang it from the curtain rod on a 12 to 18-inch thread. At dusk it glows from outside like a lantern, and it folds flat for storage.
Cost: ~$3-$10 · Renter-safe: Yes
13. Clear Ornaments Filled With Tiny Lights
Fill a clear plastic ornament with a few inches of micro LED wire and hang it with a loop from the rod. Three ornaments at different heights, about 4 to 6 inches apart, make a small cluster. The lights can be reused every year, and the ornaments pack flat in egg cartons.
Cost: ~$8-$15 · Renter-safe: Yes
14. Snowflakes With a String Light Behind Them
Cut six paper snowflakes in different sizes, tape them to the glass with removable tape, and lay a string light behind them. The glow shines through the cut-outs. Use painter’s tape for a gentler hold, and test it on a corner of the glass first. The paper costs almost nothing.
Cost: ~$7 · Renter-safe: Yes
15. A Lit Wreath on the Glass
A 14-inch pre-lit wreath on a suction hook centers well in a tall window, with the battery pack tucked behind the greenery. Pre-lit wreaths cost about $15-$25, an editorial estimate. Keep it on the room side of the glass, and check the weight limit on the hook before hanging it.
Cost: ~$15-$25 · Renter-safe: Yes
Curtains, Garland and Rods
Windows with curtains need a plan, because fabric and lights should not touch warm parts.
16. Garland and Lights on a Tension Rod
A tension rod spans a window frame with no screws, so it can hold garland and a string above the glass. Wind the light through the greenery and secure both with twist ties. Rods cost about $8-$12, an editorial estimate. The setup comes down in minutes.
Cost: ~$15-$25 · Renter-safe: Yes
17. Lights Tucked Into a Curtain Valance
Tuck a battery string behind the top fold of a valance or a pleated curtain top, where the fabric hides the wire. The light shows as a warm band across the top of the window. Use LEDs only, not older incandescent mini bulbs that run hot, and keep the battery pack within reach.
Cost: ~$7 · Renter-safe: Yes
18. A Short-Wire Setup Beside Blind Cords
If the window has blind cords, use battery lights and keep every wire short, so nothing loops near a pull cord. Place the battery box on the sill or the frame, not on the floor. This keeps children and pets away from both cords, and the blinds still open.
Cost: ~$7 · Renter-safe: Yes
Power, Timers and Takedown
Two last ideas make the display easy to live with from December through January.
19. Timers and Tested Lights
Use lights with a built-in timer, or put plug-in sets on a mechanical outlet timer, so they turn off on their own. The Consumer Product Safety Commission advises lights tested by a nationally recognized laboratory, so look for that mark on the box. A timer also saves batteries and means a window never glows all night by accident.
Cost: ~$0-$12 · Renter-safe: Yes
20. A Takedown Kit for January
Wind each string around a cardboard tube, snap the hooks into a small bag, and label the box by window. Peel adhesive hooks slowly, parallel to the wall, so paint stays put. Test a strand in November, and next year setup takes about 10 minutes.
Cost: Free · Renter-safe: Yes
Window Lighting Mistakes to Avoid
Real candles on the sill. Curtains, blinds and paper decor sit right beside a window. The U.S. Fire Administration advises keeping candles at least 12 inches from anything that can burn and considering flameless ones. On a sill, flameless is the practical choice.
Too many strands linked together. The U.S. Fire Administration holiday guidance says to inspect lights each year and follow the manufacturer’s limit on linked strands. Battery sets sidestep the problem. More traps sit in our Christmas decorating mistakes to avoid.
Cool white bulbs. Blue-white strings look sharp from the street and harsh from the sofa. Warm white feels closer to candlelight and suits the cozy look of a small apartment.
Nails and strong tape. Frames, sills and seals can be damaged by nails or heavy adhesive. Use removable hooks and suction cups, and keep the display on the room side of the glass.
Frequently Asked Questions
How do you hang Christmas lights in an apartment window?
Use small removable adhesive hooks along the top and sides of the frame, or suction hooks on the glass. Clean the surface first and space hooks about 12 inches apart. Battery lights need no outlet, and a test hook in a corner shows how the adhesive behaves.
What lights are best for Christmas windows?
Warm white LED strings work best, because they run cool and look soft from both sides. Choose battery sets, or plug-in strings with a recognized laboratory mark. The same lights suit the mantel and shelves in our Christmas living room decor ideas.
Can you put Christmas lights on a window without damaging it?
Yes. Suction cups, removable hooks and tension rods leave no holes. Avoid nails, staples and strong tape on frames or seals. Peel adhesive slowly, parallel to the surface, and test one spot first, since results vary with paint and finish.
How many strings of lights does a window need?
A 36 x 48-inch window has about 14 feet of frame, so two 12-light battery strings of about 7 feet each outline it. A smaller window needs one. For a fuller look, add a second string across the top or a jar of lights on the sill.
Is it safe to leave Christmas window lights on overnight?
It is safer to switch them off when you sleep or leave. Use lights with a built-in timer or a plug-in timer, and choose LEDs, which run cooler. Keep wires away from curtains and blind cords, and inspect each strand for frayed wire before hanging it.
