Covering a Sliding Door Without Getting in the Way of the Door

Franklin Window Treatments · 2026-09-04

Covering a sliding glass door is a different project than covering a window, even though it's tempting to shop for both the same way. The width and the fact that it has to keep opening change the list of products that actually work.

Why a Standard Window Treatment Doesn't Work on a Slider

A sliding glass door isn't just a wide window. It's a moving wall, and most standard window treatments are built for openings that stay put. Mini blinds and standard cellular shades are typically made up to about 72 to 96 inches wide in one piece, and a lot of sliders run 6 to 9 feet across, sometimes more on a newer great room addition. Order the wrong product and you'll either be short on width or stuck with a shade that's too heavy for its own lift mechanism.

There's also the fact that someone has to keep walking through it. Whatever covers a slider needs to get fully out of the way, not just raised a little, every time the door opens. A treatment that half-blocks the doorway when it's open defeats the purpose of having a door there in the first place.

That combination, width plus daily foot traffic, rules out a few options that work fine on a regular window and points Franklin homeowners toward a smaller list of products built specifically for this job.

Keeping Foot Traffic and Pets from Wrecking the Hardware

A well-designed treatment on a slider still has to survive daily use, and that's worth planning for up front rather than discovering the hard way. High-traffic doors take more bumps from shoulders and bags passing through than any other opening in the house, plus the occasional kid running full speed on the way outside.

Vertical blind vanes handle bumps reasonably well since each one moves independently, but the bottom chain that keeps them aligned is a common failure point if it gets caught underfoot repeatedly. Panel track's solid bottom rail avoids that particular issue.

Dogs that like to watch the yard are the wildcard in a lot of homes. A shade or a set of vanes left down at nose height for months on end will eventually show it, so the design plan is worth revisiting once the household's actual habits become clear, not just the measurements.

How the Main Slider Options Compare

Picking a product built for width and stacking is the fix for a Franklin slider. Vertical blinds have been the standard answer for decades because the vanes stack cleanly to one side and the design scales to almost any width just by adding more vanes.

Panel track blinds are worth a look if the vertical blind look feels dated for the room. Wide panels do the same stacking job with fewer visible seams, at a higher price point than a comparable vertical blind.

Cellular and roller shades are the wrong first instinct for a full-width slider covering unless they're being motorized or sized to just the fixed glass section. A manual cellular shade spanning 8 feet is heavy, and pulling it up and down by cord gets old fast, along with tending to lift unevenly over time as the lift cords stretch at slightly different rates.

What Sliding Door Coverings Cost

As a general national range and not a quote for any specific door, vertical blinds for a typical 6 to 8 foot slider run $150 to $400 depending on material, with vinyl and fabric at the lower end and faux wood at the higher end.

Panel track systems for the same size opening commonly run $300 to $700 nationally, and a motorized shade spanning the full width of a wide slider often lands between $500 and $1,200 depending on fabric grade and the width being covered.

Your specific door's width, whether it's a two-panel or three-panel slider, and the product category you choose all move these numbers more than a general range can capture. A free in-home measure turns this into an actual number for your Franklin home instead of a range to guess from.

The right product for your slider depends on its exact width, whether it's a two-panel or three-panel door, and how the room actually gets used day to day. A free in-home measure from Franklin Window Treatments covers all of that with real numbers instead of estimates.

Mounting and Sizing Around a Door That Still Has to Open

Mounting height and clearance matter more in a busy Franklin household than the brochure measurements suggest. The stack, whether vanes or panels, needs to clear the doorway fully when the door is open, and it needs to sit high enough and far enough to one side that a kid running through at full speed doesn't clip it.

Outside mount is standard on sliders since the door frame rarely has the depth for an inside mount, which works in your favor here too, since outside-mounted hardware sits further from the glass and slightly out of the path of daily bumps.

Door hardware needs clearance from the mounting brackets so the treatment doesn't become one more thing that has to be worked around every time someone actually uses the door. That includes any screen door track sitting outside the glass.

Frequently Asked Questions

Why does my mini blind sag in the middle of my sliding door?

Standard mini blinds are built for a window, not a wide moving door, and across 6 or more feet the slats can bow under their own weight, especially in aluminum. A product built for width and stacking, like vertical blinds or panel track, doesn't have that problem.

Should I mount blinds inside or outside the door frame?

Outside mount is standard on sliders, partly because the frame is usually thin aluminum or vinyl without enough depth for an inside mount, and partly because outside mount gives more flexibility to size around the door's moving parts and hardware.

How do I keep my dog from destroying the blinds on my slider?

Vinyl vertical blinds tend to hold up best to pushing and pawing since each vane moves independently. Keeping any fabric shade raised during the hours your dog is active in that room, or scheduling a motorized shade to lift automatically, also cuts down on wear.
