Buying your first set of blackout curtain clips seems straightforward until you see how much light still sneaks in around your panels. Even true blackout curtains often leave a bright gap where two panels meet in the middle, plus thin lines along the sides and bottom that glow at sunrise. If you work night shifts, share a room with a light sensitive sleeper, or are setting up a nursery, those leaks can make your investment feel incomplete.

Pros
- Closes the center gap between panels for complete light blocking
- Soft plastic construction holds firmly without damaging curtain material
- Lightweight and compact for easy travel and everyday use
- No tools or installation needed, just clip to side hems
Cons
- Only includes two clips, so multiple windows require additional sets
- White color may be visible on dark colored curtains
- Designed specifically for side hems of paired panels, not for other curtain styles
The SunZero Lights Out Blackout Curtain Clips are a minimalist accessory designed to solve a common blackout curtain problem, the light leak where two panels meet. Sold as a two pack, they are made for anyone using paired 100 percent blackout panels in bedrooms, nurseries, offices, or media rooms.
In use, the concept is simple and effective. You clip both pieces to the side hems where the panels overlap, pulling them together for total closure and eliminating the bright vertical gap. This creates a more consistently dark environment for sleep or viewing without adjusting rods or adding extra fabric.
Build quality is straightforward but thoughtful. The clips are made from 100 percent plastic that is strong enough to hold panels together yet soft enough to avoid snagging, tearing, or leaving marks. At just 3.75 inches wide and weighing almost nothing, they are discreet and highly portable for travel.
There are a few limitations to consider. The set includes only two clips, so covering multiple windows will require additional packs. The white color is neutral but may stand out against darker curtains, and the clips are purpose built for side hems so they are not intended as general curtain rings or holdbacks.
Overall, these clips are a smart, low cost fix for getting the most out of your blackout curtains. If you already own SunZero or similar blackout panels and still see light in the middle, this small accessory delivers a noticeable improvement with zero installation effort.

BirdNest 12 Pairs Magnetic Curtain Closure is a clever, no drill accessory designed to fix the most common blackout failure, light leaking around the edges. It is built for parents setting up nurseries, night shift workers, renters and anyone who needs true darkness without permanent hardware.
In real world use, the system clamps your blackout fabric between an adhesive metal plate on the window frame and a loose black magnetic board. Reviewers report a surprisingly strong hold that resists accidental bumps and keeps side and bottom edges sealed, with one pack often covering two standard windows.
Each fastener measures 1.75 by 0.5 inches and uses a rustproof iron front plate with adhesive and a plastic backed magnet. The low profile, two piece design is portable and leaves minimal damage, making it easy to install, remove and reposition as needed.
There are limitations to note. The adhesive can soften in high heat or direct sun, and the magnets are best suited to lightweight polyester blackout covers rather than heavy curtains. For the top edge of a cover, the brand recommends pairing the magnets with hook and loop tape for full support.
Overall, this is an affordable and effective upgrade for anyone frustrated by glowing curtain edges. If you need a simple, removable way to improve blackout performance without tools or drilling, this 12 pair set delivers strong value and reliable results.

The Curtain Clip Pro is a simple 2-pack clip system designed to pull overlapping curtain panels tightly together to eliminate light leaks. It is aimed at sensitive sleepers, parents setting up nurseries, and travelers who need darkness in hotels or rentals.
In real world use, the clips create a tight seal in seconds without tools, pins, or wall hardware. Reviewers highlight how well they close the center gap where curtains meet, improving darkness and privacy, and note they stay secure with regular opening and closing.
Each clip measures about 3 by 3 inches and is made from thick, waterproof plastic with a smooth white finish. The design is gentle on fabric, leaves no holes or marks, and looks inconspicuous once installed on white or light colored drapes.
The main limitation is coverage, as tall or floor length curtains may need more than one set to keep the entire edge closed. Some users also note the plastic build feels expensive for what it is, and the clips are not intended for blinds, shades, or very thick curtains on large rods.
Overall, the Curtain Clip Pro delivers exactly what it promises, a fast, damage free way to achieve a fuller blackout effect. For anyone frustrated by light gaps and looking for a portable, reusable solution, it is a practical and well made choice.

How to Choose Blackout Curtain Clips That Actually Work
Not all clips solve the same problem, so start by identifying where light is entering your room. Some products are made to pull two curtain panels together in the center, while others seal the edges of a panel to the wall or window frame. Knowing your leak pattern helps you pick a style that will actually darken the room instead of just adding hardware you do not need.
1. Match the Clip Style to Your Light Leak
The most common leak for beginners is the vertical gap where two curtain panels overlap in the middle. A center closure clip is designed specifically for this, and the Sun Zero Lights Out Blackout Curtain Clips is a clear example. It includes two clips that fasten to the side hems of two 100 percent blackout panels to create total closure, which is ideal if your panels look dark but still part in the center.
Side and bottom leaks need a different approach. The 12 Pairs Curtain Magnet With Adhesive,Blackout uses a two piece magnetic closure where a metal board with adhesive sticks to the window frame and a black magnet board clamps the blackout fabric between them. This system is made to reduce sunlight leakage along both sides and the bottom edge, which is especially useful for portable blackout blinds or curtains that do not sit flush against the wall. If your main issue is edge glow rather than a center gap, magnets will do more than a center clip.
2. Check How It Attaches and Whether It Protects Fabric
As a first time owner, you want darkness without holes, sticky residue on fabric, or bent curtain hems. Look closely at whether a product clamps, clips, or uses adhesive, and where that adhesive actually goes. The Curtain Clip Pro Sleep Blackout Closure (White) is designed to block light in under 15 seconds and is described as gentle on curtains without causing damage, which is reassuring if you are renting or have new curtains you do not want to puncture.
By contrast, magnetic systems often use adhesive on the window frame, not on the fabric itself. With the 12 Pairs Curtain Magnet With Adhesive,Blackout, only the silver metal board has adhesive for the frame, while the black magnetic board has no adhesive and simply holds the fabric by magnetic force. That means you can remove and reposition the blackout cover without pulling tape off the curtain. Always confirm this detail before you buy, and clean the frame thoroughly before installation so the metal plate adheres securely without needing extra tape on your curtains.
3. Consider Size, Weight, and Portability
If you travel, move between rooms, or want a solution for a nursery and a home office, bulk matters. Small, lightweight clips are easier to pack and to use on different windows without tools. The Sun Zero Lights Out Blackout Curtain Clips are made from 100 percent plastic and are described as small and lightweight for easy travel, making them a practical example of a low profile option you can keep in a suitcase or diaper bag.
Think also about how quickly you can put the clips on and take them off in the dark. A simple clamp that snaps over two hems is faster than aligning multiple magnets along an entire edge. For everyday home use, speed may matter less than a perfect seal, but for travelers or parents doing naptime on the go, a clip you can apply with one hand is valuable. Pairing a quick center clip with a comfortable blackout sleep mask can also help when you cannot fully control the room, such as in hotels.
4. Look at Quantity and Coverage Area
Beginners often underestimate how many points of contact are needed to truly block light. A set of two clips may be perfect for closing the center overlap of one window, which is exactly what the Sun Zero Lights Out Blackout Curtain Clips provides. The Curtain Clip Pro Sleep Blackout Closure (White) follows a similar approach, focusing on forcing curtains to close properly at the key gap rather than covering the whole perimeter.
If you need to seal the entire perimeter of a window, especially with a portable blackout shade that has no curtain rod, you will need more pieces. The 12 Pairs Curtain Magnet With Adhesive,Blackout includes 12 pairs of small boards, each about 1.75 inches long, so you can place several along each side and the bottom for a continuous seal. Before you buy, measure your window height and decide whether you want to cover just the center, just the sides, or all edges. For broader sleep environment improvements, many readers also explore budget white noise machines for better sleep and cooling weighted blankets for hot sleepers alongside light blocking.
Common Mistakes to Avoid
One frequent mistake is buying a center clip when your real problem is edge light, or buying edge magnets when your panels simply will not stay together in the middle. Take a photo of your window at midday with curtains closed to see where the brightest lines appear, then choose accordingly. Another error is assuming any clip works with any fabric weight. Very heavy or very sheer hems may not sit well in a small plastic clip, so check the product description for fabric compatibility and whether it will damage curtains.
Installation errors also reduce effectiveness. With adhesive based magnets, failing to clean the window frame, pressing for only a second, or placing the adhesive board on dusty or textured surfaces can cause it to fall. For the best hold, follow the recommended steps of cleaning the frame, tearing off the paper, sticking the metal board, pressing for several seconds, then clamping the fabric between the two boards. Avoid placing adhesive directly on painted drywall if you are renting, and consider adding soft glow lighting for small bedrooms for evening use so you do not need to rely on harsh overhead lights after you have darkened the room.
- Do not mix clip types without a plan. Using a center clip plus a few edge magnets is often more effective than buying many of one style.
- Do not place magnetic closures on the top edge alone without support. The maker of the 12 pair set suggests using hook and loop tape together with magnets if you need top coverage.
- Do not expect clips to fix a too narrow curtain. If panels do not overlap at all, you may need wider curtains first.
Who This Guide Is Not For
Blackout curtain clips are a targeted fix for light leaks around existing curtains, so this category is not ideal for renters who are not allowed to add any adhesive to window frames or for windows where you need a full blackout liner or custom shade instead of a small accessory. If your windows are floor to ceiling sliding glass doors, have curved bay shapes, or you need complete darkness for a home theater, a clip alone will not provide enough coverage and you should skip this type of product in favor of a full coverage solution. For those households, a professional blackout system or a fitted portable blind will be a better fit than small clips or magnets.
Frequently Asked Questions
Do blackout curtain clips work with any curtains or only blackout curtains?
Clips can physically hold most standard curtain panels together, but they work best when the fabric itself is already light blocking. A center clip like the Sun Zero Lights Out Blackout Curtain Clips is designed to be used with 100 percent blackout panels to achieve total closure, while edge magnets can help any blackout shade sit tighter to the frame. If your curtains are sheer or light filtering, clips will close the gap but light will still pass through the fabric.
Will curtain clips or magnets damage my curtains or walls?
When chosen correctly, they should not damage curtains. Products like the Curtain Clip Pro Sleep Blackout Closure (White) and the Sun Zero Lights Out Blackout Curtain Clips are described as not damaging curtains because they clamp the hem rather than piercing it. Magnetic sets put adhesive on the window frame, not on the fabric, so the curtain itself stays clean. To protect walls, avoid sticking adhesive boards to painted drywall and always clean and dry the frame before application.
How many clips do I need for one window in 2026?
It depends on where the light leaks. For a single center gap on one window, a 2 pack of center clips is usually enough. For sealing the sides and bottom of a portable blackout cover, you will need multiple points of contact, which is why sets like the 12 Pairs Curtain Magnet With Adhesive,Blackout exist. Measure the height of your window and plan to space magnets every 8 to 12 inches along each edge you want to seal for the most consistent darkness.
