If you're renting, temporary, or simply want to avoid damaging your walls and window frames, stick-on cordless blackout blinds like those from Maritown offer a practical middle ground between pinning up a sheet and investing in permanent fixtures. These self-adhesive pleated paper blinds are designed to install without tools, clips, or holes. But before you order, it's worth understanding whether this type of blind suits your needs and how to measure your windows correctly.

What Are Cordless Stick-On Blackout Blinds

Maritown cordless blackout blinds are temporary window coverings made from non-woven fabric and installed using double-sided adhesive tape rather than screws or brackets. The pleated design gives them a neat appearance while the fabric blocks light and resists UV damage. They come in multiple colors: white, blue, and brown offer light filtering, while black and grey provide blackout coverage. Because they're cordless, they're inherently safer for households with young children and pets, eliminating the strangulation hazard that traditional corded blinds pose.

Understanding the Size: 35 x 71 Inches Explained

The Maritown product measures 35 inches wide by 71 inches long and is designed to fit windows between 24 to 35 inches wide and 47 to 55 inches high. This is where many people stumble. The 35-inch width doesn't mean your window must be exactly 35 inches—it's the maximum width of the blind before cutting. You can trim the blind down to fit smaller windows. The 71-inch length works similarly; you cut it to your window's height.

Before ordering, measure your window opening in three places: top, middle, and bottom for width, and left, right, and center for height. Use the smallest measurements you get, as this ensures a proper fit without gaps. If your window is wider than 35 inches or taller than 71 inches, you may need to order multiple blinds or consider whether these temporary blinds are the right choice for that particular opening.

Installation and Maintenance Considerations

The installation process for Maritown cordless blackout blinds involves three main steps: cutting the blind to size, removing the backing from the included double-sided tape, and adhering it to your window frame or door. The tape comes 2.5 centimeters wide and is designed for strong adhesion without leaving stains when removed. However, success depends on having a clean, dry surface. Dust, moisture, or existing residue will reduce how well the tape sticks.

Each blind includes two clips for height adjustment, allowing you to raise or lower the shade without any cord mechanism. This clip-on feature is particularly useful if you want to let light in during the day but maintain blackout coverage at night. Keep the clips in a safe place, as losing them means you lose the flexibility to adjust height.

When Temporary Blinds Make Sense

These stick-on blackout blinds work best for temporary situations: rental properties where drilling is prohibited, seasonal use, or testing whether blackout coverage is right for a room before committing to permanent fixtures. They're also practical for nurseries where you want quick, tool-free installation, or bathrooms where moisture resistance matters more than durability over years.

The non-toxic, waterproof, and dustproof non-woven fabric means they can handle bathroom humidity and kitchen steam better than paper alternatives, though they aren't designed for long-term exposure to heavy moisture. Remove them periodically to wipe down dust accumulation, and avoid placing them near direct heat sources.

Getting the Right Fit with Maritown

The Maritown product description notes that if you're unsure which size suits your windows, you can contact the company and they'll respond within 12 hours with advice. This is worth taking advantage of, particularly if your windows are oddly shaped or larger than the standard 35 x 71-inch dimensions. The blinds come in carton packaging to prevent creases during shipping, so they should arrive flat and ready to cut and install.

Cordless blackout blinds are a legitimate option when you need temporary coverage without permanent installation. The key is measuring carefully and understanding that you're getting a functional, temporary solution rather than a design feature meant to last for decades.
