Most window shades go in crooked because the window got measured once, not three times. That single skipped step causes more re-drilled holes than any tool. If you’ve sorted out roman curtains, bay window curtains, and window curtain rods elsewhere in the house and now want the shades themselves to sit clean, the job splits into two paths: no-drill and drilled. The same measuring logic that saves small window curtains applies here, and once they’re up, the upkeep looks a lot like how to clean window blinds and how to clean window tracks.
Inside Mount or Outside Mount? Decide This First
Inside mount sits flush inside the window frame; outside mount covers the whole opening and fastens to the wall or trim above it. That one choice drives every measurement and every bracket after it, so make it before you touch a tape measure.
Go inside mount when the frame has enough flat depth for the headrail to recede, which most brackets put at roughly 1.5 to 2 inches. It looks tidy, shows off the trim, and keeps the sill usable. The trade-off is light leak down the sides, since the shade can’t cover the frame edges.
Choose outside mount when the frame is shallow, the window is out of square, or you want maximum darkness. Mounting to the wall lets the shade overlap the opening by a few inches on each side, which blocks the side gaps that inside mounts can’t. Apartment Therapy makes the same call for bedrooms where blackout matters more than a flush look. Renters usually land on outside mount too, because tension and adhesive styles skip the frame entirely.
How Do You Measure a Window for Shades?
Measure the width in three places, top, middle, and bottom, then use the narrowest number for an inside mount. Windows drift out of square as a house settles, and that 1/8-inch difference is exactly what leaves a shade jammed on one side.
For inside mount, measure the exact opening and don’t subtract anything; the manufacturer builds in the deduction, usually about 1/4 to 1/2 inch of clearance so the shade clears the frame. Measure height in three spots too, left, center, and right, and take the longest for full coverage. Write width first, always, because every shade spec reads width by height.
For outside mount, add overlap. A common rule is 2 to 3 inches beyond the opening on each side and 2 to 4 inches above, which hides the hardware and cuts side light. Wirecutter’s install guidance leans on that same overlap for real darkness. Measure the depth of the frame with the tape held flat against the glass; that number tells you whether an inside mount even fits.
How Do You Install No-Drill Cordless Shades?
No-drill shades hold with either spring tension inside the frame or adhesive strips on the frame face, so the whole install runs on measurement accuracy rather than power tools. Wipe the mounting surface first. Adhesive won’t grip dust or old paint film.
For tension-style cellular shades, compress the headrail spring, seat one end in the frame corner, then let it expand into the opposite side. Push firmly and check the bottom rail with a level. If it sags on one side, the frame is out of square and you’ll shim the low bracket with a folded card.
For adhesive shades, peel a short section of backing, align the top edge to your pencil line, and press from the center outward to push air out. Hold each strip for the full 30 seconds the label asks for; that cure time is what stops a slow peel a week later. These styles carry a real weight ceiling, so heavy blackout fabric on a wide window is the usual failure point. Keep adhesive runs under a couple of feet of span and they stay put.
How Do You Install Drilled Shades With Brackets?
Drilled shades mount on two or three brackets screwed into the frame or wall, and the only hard part is getting those brackets level and evenly spaced. Mark the bracket positions from your measurement lines, not by eye.
Hold a bracket at each end of the headrail, about 2 to 3 inches in from the shade edge, and mark the screw holes with a pencil. Add a center bracket on any shade wider than about 30 inches so the rail doesn’t bow. Drill pilot holes one size under the screw diameter; into drywall without a stud behind it, set a plastic anchor first or the screw strips out within a season.
Level the marks across the top before you drive a single screw. Fasten the brackets, snap or clip the headrail in, and operate the shade fully up and down to confirm it clears the frame. A shade that binds usually means one bracket sits a hair proud of the other. Loosen it, nudge, retighten.
What You’ll Need
These five no-drill and cordless options all clear a 4.2 owner rating and skip the wall damage that trips up renters, listed easiest-to-remove first; the Maritown sits at 4.2, the lowest here, which for a cut-to-size paper shade usually signals more variation between units than a cellular shade shows.
Pros

This is the shade renters have been waiting for. The no-drill spring rod system means you can finally have real window treatments without losing your security deposit or annoying your landlord. It clicks into place in under a minute, holds securely, and comes down just as easily when you move.
Beyond the installation convenience, the honeycomb design actually works. Those air pockets trap heat in winter and block it in summer, which means lower energy bills and more comfortable rooms. The cordless lift is smooth, the light filtering fabric softens harsh sunlight without making rooms feel dark, and the clean lines look polished in any space.

Frequently Asked Questions
Can you install window shades without drilling?
Yes. Tension-mount cellular shades and adhesive roller styles hold without a single hole, which is why they’re the default for rentals. The limit is weight and span, so wide blackout panels do better on brackets.
How do I know if my window fits an inside mount?
It depends on frame depth. Measure the flat surface from glass to front edge; most inside-mount brackets need roughly 1.5 to 2 inches. Less than that, and you’re mounting outside the frame instead.
Which do I write first, width or height?
Width, always. Every shade spec reads width by height, so a 22 by 36 order means 22 inches wide. Flipping the two is the most common ordering mistake people make.
Do no-drill shades damage the wall or frame?
Almost never on the frame face, though strong adhesive can lift loose paint on removal. Warm the strip with a hair dryer before peeling and it releases clean. Tension styles leave nothing behind.
How much overlap does an outside mount need?
Plan on 2 to 3 inches past the opening on each side and 2 to 4 inches above. That overlap is what actually blocks the side light gaps that an inside mount can’t reach.
Why does my shade sit crooked after install?
Usually the window is out of square, not the bracket. Recheck with a level, then shim the low side with a folded card or reset one bracket. A 1/8-inch frame drift is enough to show.
Can one person install a window shade alone?
Yes for most standard windows under about 36 inches wide. Wider or heavier headrails go easier with a second set of hands to hold the rail level while you drive the screws.
Bottom Line
Measure the width in three places and mount to the narrowest number; that one habit fixes most crooked, binding, light-leaking installs before they happen. Renters and anyone avoiding wall holes should reach for a tension or adhesive shade and skip the brackets entirely. Drill only when the window is wide, heavy, or you need true blackout with an outside mount. If the frame is badly out of square or you’re cutting into plaster over lath, that’s the point to bring in a pro.
