Sliding Glass Door Curtains: Tips & Ideas to Manage Light, Privacy & Style

A wall of sliding glass is one of the loveliest things a home can have: all that light, the patio right there, the room seeming to carry on outdoors. It comes with a few trade-offs, though: privacy after dark, glare at midday, a chill in winter, and a lot of hard, shiny surface. The best sliding glass door curtains answer all of that with full-length panels on a rod or track that runs well past the frame, so they slide clear of the glass by day and close snugly at night. Sheers soften the light, blackout suits a bedroom, and an easy-gliding heading is kind to doors you use all day. So if you're gathering drapery ideas for your sliding patio doors, read on for our stylists' favorite ways to dress them, from fabric and color to fullness, length and hardware.

From blackout curtains that block harsh light to delicate sheers that offer semi-privacy, and all in between—custom curtains can be tailored to meet every requirement and taste at Sewn, where the choice range runs to more than 2,500 fabrics. However, before you start browsing our catalog, take a few moments here to explore recommendations from our drapery experts so you can choose curtains for your sliding glass doors that are as functional as they are beautiful.

One Story, Two Perspectives: Consider the View from Both Sides

If the sliding glass doors serve as room dividers or are connected to an outdoor living area, the curtains must look good from both sides. Besides having to complement the decor scheme and palette on both ends of the room, this calls for deeper thought on several design decisions, such as:

FABRIC: The fabric must be presentable on the rear side, if not the same as the front. So, one-sided velvets, embroidered fabrics, one-sided printed fabrics, and so on call for a deeper consideration. Instead, look for fabrics that look presentable on both sides, whether plain or printed. 

Furthermore, turning a limitation into an opportunity, you can consider double-sided curtains too, where you can curate the drapery to diverse tastes by choosing two distinct fabrics. You can pair a solid and a pattern, or a linen with a velvet, or a color with a neutral—creating an entirely different aesthetic on either side with the same drapery. Note that sticking to light-weight fabrics will be beneficial for this approach - especially over-wide doorways - as double-sided curtains can otherwise get quite heavy to operate. 

LINING: Although we recommend lining drapes for aesthetic and functional benefits, internal glass door curtains are an exception. Consider whether the flat look of the lining will tally with your desired aesthetic on the other side of the room, and avoid lining if it doesn’t.

HEADING STYLE: The design of the top header of a curtain panel is referred to as heading style. While heading styles like pinch pleats look elegant from the front, they are less appealing on the back. Where the headers will be visible on both sides, choose styles like rod pockets, flat panel tops, grommet tops, tab tops, and hidden back tab tops that look (almost) equally good from front and back.

Light, Mood & Ambiance: Pick the Right Fabric & Lining

Fabric is the most important component that you have to get right when it comes to glass door curtains. Alongside aesthetics, two other aspects have to be considered: the composition and the opacity, all within the context of whether the doors are internal or external.

COMPOSITION: Curtains are the mouthpieces of your decor style and instantly set the tone of the room. The composition, weave and finish of the fabric ideally have to go with your aesthetic. Silk and velvet curtains are the topline choice for formal areas as their luster brings a sense of occasion. Cotton and linen curtains are considered ideal for semi-formal and informal rooms as their homespun textures ground the space in a homely charm. 

OPACITY: The curtains’ opacity will directly impact light control and privacy. So, choose the opacity level based on how much light you want to let in and the privacy guards you want to have in place: 

• Semi-sheer and sheer curtains are ideal for patios where you want the light to filter in gently throughout the day, and for internal glass doors where the goal is semi-privacy. Our sheers have a chain weight sewn along the hem, so they hang straight and settle neatly after every slide of the door.

• Non-sheer curtains are apt where the goals are round-the-clock privacy and enhanced light control—the kind that sheer curtains can’t meet.

• Blackout curtains block most light and muffle outside noise, making them ideal for bedroom patios and internal glass doors where privacy and room-darkening matter most.

LINING: Curtains on external sliding glass doors benefit from lining as they are continuously exposed to sunlight. Especially fabrics like bright cotton and pure silk, which are prone to sun damage, find lining a necessity, not a luxury. Depending on whether you’re looking for room-darkening or merely a layer of protection, choose between our privacy and blackout linings. Head to Sewn’s Lining Options to discover the benefits and key considerations for each choice. Both linings are sewn in, and our blackout lining comes in white, pale gray or pale beige, so it can sit behind a light or a deep fabric without changing how the curtain looks from the room.

Color Story & Theme: Choose Palette & Pattern with Intention

Unlike off-the-shelf vertical blinds, which come in only a few plain neutral hues, curtains hold a huge promise with their vast range of choice.  So, use the opportunity to choose colors and patterns that forward your decor style and add personality to your space. 

Floral curtains add a layer of vibrance and an outdoorsy feel well-suited to cottagecore themes and nature-inspired decor styles. Plaids and stripes ground the space with their straight lines, contrasting the embellished silhouettes of classical design styles, and complementing the sleek features of minimalist interiors. Geometric and abstract patterns have a pronounced modern edge that instantly blends with bold contemporary interiors. Let your overall aesthetic guide the choice of palette and pattern for your sliding glass door curtains.

Pleats, Folds & Beyond: Choose a Befitting Heading Style

The structure of the curtain header impacts both the visual appeal and functional ease of the curtains. That’s why Sewn offers more than a dozen heading styles to cater to the distinct settings and decor styles. Explore these in our Drapery Headings Style Guide as you evaluate them on these parameters:

AESTHETIC: Each heading style creates a distinct look—pinch pleats bring tailored elegance to formal spaces, tab tops carry a casual flair, ruffled rod pockets infuse a cottagey vibe, and back tab tops offer a crisp modern edge. Choose the heading style that rhymes with your aesthetic.

EASE OF GLIDE: Curtain styles with rings/pins/grommets offer an effortless glide, making them perfect for curtains that will be frequently adjusted to the shifting light. But for privacy curtains that must hold their positions rather than move easily with the winds, pick curtains with fabric pockets or tabs.

LIGHT BLOCKAGE: In sleeping areas and entertainment rooms with blackout goals, go for styles that offer full coverage headers, such as the pinch pleats and flat panels. And, in places like the kitchen patio that love a breezy touch, opt for styles with semi-coverage headers like tab tops, tie tops, and so on. 

HARDWARE: If your sliding glass doors are already furnished with drapery hardware, make sure that your curtains are compatible with it. Because while most heading styles can go on both tracks and rods, some are designed specifically to work with one or the other.

HomeSewn Wisdom: Heading styles for curtains of interior glass doors have one more criterion to fulfill; they must look neat on the reverse side as well. So, avoid styles like pinch pleats, which do not present quite as well on the reverse. Instead, opt for headers such as rod pockets, tab tops, grommet tops, flat panel tops etc. that look ‘almost’ the same on both sides. 

Style, Balance & Functionality: Determine the Number of Panels

Whether to go for a sweeping single-panel curtain or the standard double-panel drapery style is a decision that hinges on your doorway’s width and the aesthetic you’re after.

A single-panel, one-sided pull curtain is most apt for a narrow doorway where leaving one side free for passage makes for maximum practical ease. A lush curtain gathered like a swag to one side and tucked in a fancy hold-back is an aesthetic statement befitting the grandeur of glazed doorways.

Double-panel curtains suit a wide doorway where single-panel curtains may look out of balance. Curtains framing the doorway on both sides ring in harmony and symmetry. Distributing the weight also makes it easier for the drapery to operate.

Hemlines, Fullness & Coverage: Tailor the Length & Width

Curtains perform their aesthetic and functional roles best when sized correctly, especially when it comes to glass door curtains, where privacy, insulation, and light control enjoy prominence. Hence, keep the following in mind when finalizing the length and width of your sliding glass door drapes:

LENGTH: That glass sliding door curtains have to be floor-length is a given, but their start and drop are two details that need to be considered carefully. We suggest mounting the curtains at least 6-12 inches above the door trim for a well-finished look and to contain light leaks. If you’d like to emphasize the vertical span of the room, mount the curtains as high as possible or onto the ceiling itself. 

Decide the exact drop point based on how you plan to use the drapes. Extravagant puddling suits for decorative drapes that are not expected to be operated. But for functional curtains that you will draw open and close every day, the ‘float’, ‘graze’, and ‘break-puddle’ positions are ideal to ensure a smooth glide on the rod.

WIDTH: Curtain width and fullness shape both privacy and looks: fuller curtains close more snugly at the edges and hang in richer folds. For grommet, rod pocket, back tab, flat panel and pencil pleat curtains, aim for 2x fullness, or a total width twice the length of the rod, and don't go below 1.5x. Tab tops and tie tops look best at 1.5x. Pinch pleats have their fullness sewn in, so on a decorative rod, order a single panel at the rod length plus 6–8 inches, or a pair at (rod length + 12 inches) ÷ 2 each. Our panels can be made up to 288 inches wide; anything wider than about 48 inches has a vertical seam, and we match the pattern across it. More on what ‘fullness’ means and how it is calculated in our Drapery Measurement Guide.

Tracks, Rods & Placement: Mount Hardware Correctly

Hardware decisions impact the overall look of your curtains. And how the hardware is positioned will affect light inflow and coverage. So, whether you choose a sleek, minimalist curtain track or a traditional decorative drapery rod, position it in a way that favors your settings. 

First of all, mount the rod/track as close to the ceiling as possible, or on the ceiling itself. This thoughtful placement will make the curtains a visual connection between floor and ceiling, drawing the eye upward and making the ceiling look taller. It’s a small detail that will go a long way in adding a note of grandeur to the overall room.

Secondly, extend the track/rod 6-12 inches beyond the trim on either side, so the curtains can slide off the doorway and stack on the wall. So, size the rod generously, and enable the curtains to clear the doorway to make the most of your sliding glass doors.

When you plan that extra width, allow for how much room the open curtains take up. Grommet, rod pocket and flat panel curtains usually stack to about 10–12% of their width, and pinch pleats to about 15–20%. So a generous rod lets the whole stack sit on the wall, leaving the glass completely clear. Sewn doesn’t sell drapery hardware, so choose your rod or track first, then measure it end to end and order the finished size of each panel.

Sliding Glass Door Curtains: FAQs

What size curtains do I need for a sliding glass door?

Measure your rod or track, not the door. For most gathered headings, order a total curtain width about twice the rod length, split into one or two panels. For length, measure from where the heading sits on the rod down to where you want the hem, and order that finished size.

How high should you hang curtains over a sliding glass door?

At least 6–12 inches above the door trim, or close to the ceiling if you want the room to feel taller. Mounting high also helps cut the light that leaks over the top.

Should a sliding glass door have one curtain or two?

One panel suits a narrower door, drawn to the side that doesn’t open so the walkway stays clear. Two panels suit a wide door, look more balanced, and split the weight so each side is easier to draw.

How do you keep curtains from blocking a sliding door when they’re open?

Extend the rod well past the frame on both sides so the curtains can stack on the wall. Allow roughly 10–12% of the curtain width for grommet, rod pocket or flat panel styles, and 15–20% for pinch pleats.

What curtains work best on a kitchen sliding door?

Light, easy-moving curtains on grommets or rings, in a length that floats just above the floor so they stay clear of busy feet. A privacy lining or a semi-sheer keeps the room bright while softening the glare.

What curtains look good on both sides of an interior glass door?

Choose a fabric that looks finished on the back, an unlined or double-sided curtain, and a heading such as grommets, rod pockets, flat panels or tabs, which look much the same from either side. Pinch pleats show their tape on the back.

Do curtains help keep a sliding glass door warmer?

They can help. Full, lined curtains drawn at night add a soft layer over the glass, and blackout lining in particular helps with heat in summer and chill in winter. For the best effect, hang them high and wide so they close snugly at the edges.
