Christmas window decor for a small apartment comes down to one question: how much can the sill actually hold? Mine is barely three inches deep. Every idea here fits a narrow ledge, a tension rod, or a couple of damage-free hooks. Nothing needs drilling and nothing eats floor space; in January it all comes down without leaving a mark. These are the five window decorations I would pick for a small space. Every one of them is easy to find on Amazon US right now.
1. Line the sill with electric window candles
A row of candle lamps gives you that old city street glow. It reads as Christmas from both sides of the glass. The trick for a small sill is the base: most candle lamps are too wide and tip over. This 6 pack of SURAIELEC plug in window candles has a slim 1.7 inch base that sits comfortably on a narrow ledge. Each candle has its own cord with an on/off switch, and the gloss gold finish looks warm instead of cheap. The set is UL Listed, priced at $33.99 and in stock at the time of writing. Skipping the big tree this year? These candles pair nicely with any of these Christmas tree alternatives for small spaces.

2. Hang a prelit wreath inside the window
Hang a wreath inside the window with a wide ribbon over the top frame. It becomes a lit centerpiece you can enjoy from the sofa, and the neighbors get the view too. This 18 inch prelit wreath comes decorated with red berries, snow dusted tips, pinecones and little candy cane accents. There is nothing extra to buy. The warm LED lights run on a 6 hours on, 18 hours off timer with 7 light modes. Set it once and it greets you every evening. The wreath sells for $37.99 and was in stock when I checked. The same no holes logic from our renter friendly holiday door decor applies here: a ribbon or a small adhesive hook is all you need.

3. Turn the glass into a curtain of lights
If your window is the biggest decorative surface you have, curtain lights are the highest impact move. This HEYFUNi curtain measures 6.6 by 6.6 feet with 200 warm white LEDs. That covers a standard apartment window from frame to sill. It plugs in and comes with a remote, 8 lighting modes, a timer and a memory function. It restarts on your favorite setting every night. Several sets can connect together if you ever decorate a bigger window. It goes for $19.98, in stock at the time of writing. In a small living room, this kind of glow can honestly replace a tree on dark evenings. If you want both, here is how to fit a Christmas tree in a small apartment without giving up the window.

4. Frame the window with a pre lit garland
A garland around the frame makes even a plain rental window look like a storefront. This 6 foot lighted garland carries 30 LEDs: star shaped lights, classic bulbs and fiber optic strands. Red berries and pinecones sit in the greenery. It runs on 3 AA batteries, so there is no cord to hide, and the built in timer keeps it on a schedule. It costs $22.99 and was in stock when I checked. Six feet is enough for the top and partway down both sides of a small window. The same clear adhesive hooks that hold stockings when you have no fireplace will hold a light garland like this around the frame.

5. Hang a glowing star in the glass
The simplest christmas window decor idea on the list: one lighted silhouette hanging in the window. This 2 pack of 16 inch window silhouette lights includes a Bethlehem star and a nativity scene. Each one carries 45 to 56 warm LEDs on a slim frame. They plug in with UL certified adapters and a 2 meter lead wire, so reaching an outlet is easy. The set goes for $29.99, in stock at the time of writing. Hang the star with a suction hook at the center of the glass and the window does all the decorating for the whole room. It is the same trick Scandinavians use all winter: one warm point of light per window.

Once the window glows, the rest of the room asks for very little. A blanket on the sofa, maybe a small hot cocoa bar in the kitchen, and the apartment feels like December. Start with whichever christmas window decor idea fits your sill.
