Our patios come in two sizes to fit nearly any standard (up-and-down) window. Please note they are not compatible with sliding windows or roll-out window frame styles.
To determine the right size for your window, open the window you plan to use and measure the width of the open space — from one inside edge of the window frame to the other. (Keep in mind: the narrowest part of the frame is often near the screen track, so be sure to measure far enough back into the frame if space is tight.)

If your measurement is greater than 25 inches, you’ll need the large size.
-
If it’s under 25 inches, one of our smaller models will be the perfect fit.
And don't worry — if you end up needing a smaller patio, you’re not settling! Cats absolutely love the smaller units, sometimes even more than the larger ones. (After all, cats and cozy spaces go hand-in-paw!)
