Measuring Guide
Measuring Guide
Choosing a Sleepout® Portable size is easy! 1) Just measure your window glass, and 2) choose a curtain larger than the window glass.
For example, if your window is 36in width my 56in length, our standard size will work perfectly!
For windows larger than both of our sizes, two curtains can be combined for total coverage.

Will it work on my windows?
Of course! Sleepout can work on any window.
Easily adjusts to fit different-sized windows.
As long as the glass of your window is smaller than the curtain, you will get 100% coverage with extra fabric folding away.
Single Pane
Two suction cups in the top corners, and you're all set! The cups are sloped towards the windowframe at the top to prevent light gaps.
Double Pane/Sliding
We recommend purchasing an extra curtain so each window will have it's own panel.
Wide Windows
Sleepout Portable installs horizontally or vertically. An extra cup in the middle will help provide extra support. Or combine two panels.
Bay Windows & Shapes
Sleepout works on bay windows & round windows, too! We recommend extra suction cups to keep the curtain tight to the glass.
Got Questions?
How does it work?
How does it work?
Sleepout Portable uses patented locking suction technology that allows it to stay up on any window as long as you want.
The suction cups attach anywhere along the edge of the curtain, allowing you to find the perfect fit.
We use the highest-quality 100% blackout fabric that is lightweight, easy to install and easy to adjust.
Can I install them vertically and horizontally?
Can I install them vertically and horizontally?
Yes! There is velcro around all edges so you can install the Sleepout Portable both ways.
Does it work with Blinds?
Does it work with Blinds?
Yes! Simply install the Sleepout Portable behind your blinds, between the blinds and the glass of your window to block out light. Suction cups are only 1.5 inches tall, so that means they work under all blinds, shades or shutters.
How does it block light around the edges?
How does it block light around the edges?
Sleepout® Portable installs directly against the glass of the window to stop any light from coming into the space between your shade or curtains and the glass. For total darkness, we suggest using our adhesive mounts to close light gaps if needed.
Do I need a custom size?
Do I need a custom size?
Nope! Sleepout® works as long as the curtains you order are large enough to cover the window. No need to cut or customize the size.
