Best window treatments for sliding glass doors
The widest opening in the house, used as a door several times a day. Only a few coverings survive both facts.
By Janet H. · Last updated October 15, 2026 · How we choose
For most sliding doors the covering that works is a panel track such as the CHICOLOGY Panel Track Blinds — fabric panels that slide sideways on a headrail and park clear of the opening. If the door needs to be genuinely dark or genuinely warmer, the answer is long blackout curtains on a rod mounted above and well past the frame, drawn one way. Everything else on this page is for a specific constraint: a rental you cannot drill, a door you want to keep seeing through, or a set of vertical blinds you would rather replace like for like.
A patio door breaks the ordinary window rules in four ways at once. It is 60 to 96 inches wide, which is wider than nearly any window in the house. It is a door, so the covering has to get completely out of the way several times a day rather than merely rise. It has a handle and a track that an inside-mounted covering fouls. And it is the single largest area of glass in the room, so whatever hangs on it decides how hot the room gets in July and how cold it feels in January.

Before the list
What the door changes about the choice
Width is what eliminates products. A horizontal blind at 80 inches is a heavy object on one lift mechanism, and it sags along its length however well it is made. A roman shade at that width becomes a made-to-measure item with a slow, heavy lift. The coverings that scale to a door do it by splitting the load — vertical vanes, sliding panels, or curtain panels added to a longer rod.
Traffic is what eliminates the rest. A covering on a door has to stack somewhere that is not in front of the opening you walk through. That is why almost everything that works on a slider moves sideways rather than up: panel tracks, vertical vanes and curtains all park against the wall at one end, and the door stays usable with the covering still fitted.
The detail people miss until the box is open: which leaf slides. On a standard two-panel door one half is fixed and one moves. A covering that stacks onto the fixed side keeps the operating side permanently clear, which is far more livable than a center split you have to part every time you go outside. Check your door before you order a left or right stack.

01 — Best overall
Panel Track Blinds for sliding doors
CHICOLOGY
Four fabric panels on a headrail that slide sideways and stack on top of one another at one end, so the covering parks clear of the opening instead of being raised out of the way. Cordless, mounts to the wall or ceiling above the frame, and the listing states a fit range of roughly 46 to 86 inches wide with a height you trim yourself.
Who it’s for: A standard six to eight foot slider in a living or dining room where the door is used daily and the room should stay bright.
The catch: It does not make a room dark and does no thermal work — fabric panels with gaps where they overlap. The stack also needs somewhere to go: with no wall beside the door it parks over the glass, and the fabric is a spot-clean item rather than a washable one.

02 — Best for darkness and warmth
Thermal Insulated Blackout Curtains, long drops
NICETOWN
Long blackout panels in a drop that actually reaches the floor from a rod mounted near the ceiling — which is the mechanism behind a dark room, not the fabric on its own. Drawn one way so all the fabric stacks on the fixed side of the door.
Who it’s for: Bedrooms with a slider, media rooms, and any patio door that makes the room cold in winter or unusable in the afternoon sun.
The catch: Needs real wall space beside the door for the stack, and a rod long and stiff enough to span the opening plus the overlap without bowing. Floor-length panels by a door you use constantly also get walked on and caught, so the hem height has to be right first time.

03 — The rod that makes curtains possible
Lockseam 2 inch clearance curtain rod, 66-120 inch
Rod Desyne
A heavy lock-seam rod in a span long enough to cross a patio door with overlap left over, and enough clearance from the wall that the panels hang past the frame rather than against it. The hardware half of the curtain answer, and the half people forget to budget for.
Who it’s for: Anyone hanging curtains over a slider, which is nearly everyone who wants the room dark.
The catch: A rod this long needs a center support, and a center support means the panels cannot be drawn past the middle in one pass. It also has to be fixed into studs or proper anchors: lined panels at this width are real weight, and two drywall plugs will pull out.

04 — Best with no drilling
No Drill Cordless Cellular Shades for Doors
LazBlinds
A door-proportioned honeycomb shade that clips to the glazing bead without screws, so it covers the glass, insulates it a little, and travels with the panel it is fixed to instead of fouling the track.
Who it’s for: Renters, metal or clad frames nobody wants to drill, and anyone who would rather cover each panel of the door independently.
The catch: It sits on the glazed panel only, so it covers neither the frame nor the gap where the two panels overlap — light and sightlines get through at the edges. A door shade also hangs free at the bottom unless it is secured, and can swing when the door is slammed.

- Covers
- One glazed panel each
- Operation
- Cordless
- Mount
- Glazing bead, no screws
- Insulation
- Some, honeycomb cells
- Night privacy

05 — Best like-for-like replacement
Vertical Blinds, 3.5 inch PVC vanes
CHICOLOGY
The traditional patio-door covering, sold in door sizes: PVC vanes on a headrail that tilt for light control and draw to one side to clear the opening. If you are replacing a set that came with the house and the brackets suit it, this is the least disruptive swap there is.
Who it’s for: Rentals and resales where verticals are expected, and anyone who wants tilt control across the whole door rather than panels that only open or close.
The catch: Vanes rattle in any draft, unhook when a pet or a child pushes through them, and read as a rental fitting however new they are. Vinyl vanes also hold a curl from the packaging for weeks, and do nothing at all for heat loss.
At a glance
- Covers
- Full door width
- Operation
- Tilt, then draw to one side
- Mount
- Wall or ceiling, outside
- Insulation
- None
- Night privacy
- Yes, with vanes closed

06 — Best cheap daytime layer
Solid color sheer voile panels
MIULEE
Inexpensive grommet voile panels to hang in front of the glass, or on a second rod in front of blackout curtains. They soften a wall of glass, take the hard edge off low sun, and give a degree of daytime privacy without darkening the room.
Who it’s for: Sliders that look bare, rooms that need the glare dulled rather than blocked, and anyone layering sheers with heavier panels.
The catch: Sheer fabric provides no privacy after dark and no thermal benefit whatsoever — once the lights are on, a voile panel shows the room. Thin fabric at this price also creases out of the packet and needs hanging to drop.

Buying guide
What actually matters
Measure the opening and the wall, not the glass
Almost every covering here is mounted outside the frame, so the measurement that matters is the opening plus the overlap you want on each side, plus the height from the mounting point to the floor. Allow a minimum of 2 to 3 inches of overlap beyond the frame for a shade and 8 to 12 inches for curtains, and check there is wall or ceiling to fix into at that width — on many sliders the frame runs close to a corner or to the ceiling line. How to measure for blinds and how to measure for curtains have the full method.
Stack space decides how it feels to live with
Every sideways covering parks somewhere. A panel track stacks its panels on top of one another at one end, typically taking a band of wall or glass roughly the width of one panel. Vertical vanes bunch into a block at the stacking end. Curtain panels gather into about a foot of fabric per panel. If there is no wall beside the door, that stack sits on the glass and you have made the opening narrower. Measure the wall you have before you decide which way it should stack.
Mount outside the frame, high and wide
Inside the recess a covering fouls the handle, interferes with the track, and leaves a light gap down both sides of eight feet of glass. Outside the frame it clears all of that and overlaps the edges. Mounting high also matters more on a door than on a window, because the covering has to clear the head of the frame and still finish at the floor. Inside mount vs outside mount has the general rule, and it tilts almost entirely to outside here.
Decide whether you want darkness or a view
This is the honest fork in the road. Fabric panels on a track, solar screens and light-filtering vanes keep the room bright and give you daytime privacy; none of them make the room dark, and solar fabrics reverse after dark so the room is visible from outside once the lights are on. Blackout curtains make the room dark and warmer; they also cover the view completely when closed and need wall space to stack onto. Trying to buy one product that does both is the most common regret on a patio door. Two layers — a filtering covering for the day, curtains for the evening — is usually cheaper and always better.
A slider is the biggest heat leak in the room
A patio door is a wall of glass, so it drives both winter heat loss and summer heat gain more than any window in the house. Panel tracks and vertical blinds do essentially nothing about it, because air moves freely through and behind them. Honeycomb cellular fabric traps a layer of still air against the glass and is the only covering in this category that does measurable thermal work; lined curtains with proper returns at the sides come second. If the room is uncomfortable rather than merely bright, read best insulated cellular shades and how to stop window drafts before you buy anything decorative.
Renting, or a door you cannot drill
Plenty of sliders sit in rentals, and plenty of frames are metal or clad in something a landlord does not want screws in. The route that works is a no-drill shade fixed to the glazing bead of each panel, which travels with the door it is mounted on and so cannot foul the track. A tension rod will not help here — there is rarely a recess to brace against, and no tension rod carries eight feet of curtain. Window treatments for renters covers the wider set of options.
Cords, children and pets
A door-width covering has long operating cords if it has any at all, which is exactly the hazard the cordless window covering standards exist to address. Everything recommended here is cordless or hand-drawn for that reason. If you inherited a corded vertical blind with the property, the chain and the cords are the first thing to deal with. Pets matter too: vertical vanes sit at nose height and unhook easily, which is a recurring complaint from dog owners.
Decision
Which one for your problem
| Your problem | What to fit | Why |
|---|---|---|
| Glare and daytime privacy, view still matters | Panel track | Slides clear, keeps the room bright, no rattle |
| The room has to be dark | Blackout curtains, mounted wide and high | The only option here that overlaps the edges |
| The room is cold or roasting | Cellular shade on the glazed panel | Honeycomb traps still air; nothing else here does |
| You cannot drill anything | No-drill cellular shade on each panel | Fixes to the glazing bead, travels with the door |
| Replacing tired vertical blinds | New vertical blinds or a panel track | Same headrail logic, same stacking behavior |
| You want to soften the glass, nothing more | Sheer panels on a long rod | Cheapest way to make a slider look dressed |
Layering
The combination most people end up with
On a living room slider, the arrangement that holds up is a sideways-sliding covering doing the daytime job and curtains outside it doing the evening one. The panel track or vertical blind handles glare and the neighbors at 3pm with the door still usable; the curtains close at night for darkness, warmth and the softness a hard covering cannot give a room. It costs more than one product, and it is the reason patio doors so often look half-solved when only one layer is fitted.
Methodology
How we chose
Selection is on published maximum width, how and where the covering stacks, whether it clears a door handle and track, mounting method, and whether the maker states an insulating construction. Every product here was checked as currently sold and in stock at the time of writing. We do not install these ourselves and publish no measured figure of our own — where a number appears it is the manufacturer's published figure. Methodology.

FAQ
Questions people actually ask
What is the best window treatment for a sliding glass door?
A panel track for most doors: it slides sideways, parks clear of the opening and keeps the room bright. If the room has to be dark or warmer, long blackout curtains on a rod mounted above and well past the frame beat every hard covering, because they are the only option that overlaps the wall at the edges.
Should a covering for a sliding door be inside or outside mounted?
Outside, in nearly every case. Inside the frame the covering catches the handle, interferes with the track and leaves a bright gap down both sides of a very wide opening. The exception is a shade fixed to the glazed panel itself, which moves with the door and cannot foul it.
Are vertical blinds still a good idea on a patio door?
They work, and they are the cheapest covering that spans a door and stacks clear of it. They also rattle in a draft, unhook when a pet pushes through, and date a room. A panel track does the same job in fabric with far less noise, which is why most people replacing verticals move to one.
How do I cover a sliding glass door in a rental?
No-drill cellular shades clipped to the glazing bead of each panel. They need no screws in the frame, they travel with the door, and they come down cleanly when you move. A tension rod is not a route here: there is usually no recess to brace in, and no tension rod carries eight feet of curtain.
What length curtains do I need for a sliding glass door?
Measure from where the rod will sit, which should be several inches above the frame, down to the floor, then take off about half an inch so the panels clear it. Most patio doors need a 95 or 108 inch drop rather than the common 84, because the rod is mounted so much higher than the door head.
Do blinds or curtains help with the cold coming off a patio door?
Cellular shades help most, because the honeycomb traps a layer of still air against the glass. Lined curtains with returns at the sides come second. Panel tracks, vertical blinds and rollers do essentially nothing, since air moves freely behind and through them.
