Large Window Treatments & Blinds

Blinds for Large Windows | Custom Window Treatments for Big Windows

Large windows flood your home with natural light and create stunning focal points. They also present a unique challenge. You need window treatments for large windows that handle the scale without sacrificing style or function.

We've spent over 25 years helping homeowners find solutions that actually work for big windows. Here's what makes the difference.

What Works for Large Windows

Blinds for large windows need to be durable, easy to operate, and proportional to the space. Not every window treatment can handle wide or tall expanses of glass. The ones that do transform how your room looks and feels.

Cellular Shades

Cellular shades excel as large window blinds because they're lightweight yet strong. The honeycomb structure provides insulation with R-values up to R-4, cutting energy costs year-round. Light filtering fabrics soften harsh sunlight. Blackout options work beautifully for bedrooms and media rooms.

Our Blindsgalore Select Motorized Wand Cellular Shades come in single and double cell construction. A double cell gives you better insulation. Light filtering fabrics are spunlace nonwoven polyester that gently diffuses light. Blackout fabrics use the same material bilaminated with mylar to block light completely.

Motorization is key for blinds for tall windows. The rechargeable battery lasts months between charges. No pulling heavy shades by hand. Just smooth, effortless operation.

Roller Shades

Blindsgalore Envision Light Filtering Roller Shades and Blackout Roller Shades offer a streamlined look for window treatments for wide windows. They roll up completely when you want the view clear. Roll down for privacy and light control.

Light filtering fabrics create a soft glow while reducing glare. Blackout options eliminate nearly all light. The fabric-wrapped bottom rail creates a finished look. All components color-coordinate with your selected fabric.

Roller shades work especially well for modern spaces where clean lines matter. Motorized options make operation simple on tall or hard-to-reach windows.

Custom Drapery

Fabric drapery brings warmth and elegance that other window coverings for large windows can't match. Our Blindsgalore Designer Custom Drapery comes in ring top, grommet, and other styles that slide smoothly on decorative rods.

Add a room darkening, thermal, or premium blackout liner for light control and insulation. Drapery panels stack to one or both sides, framing your windows beautifully. Fabric options range from airy cotton-like textures to bold, design-forward patterns.

The look is sophisticated and customizable. Choose from over 146 available colors and patterns to match your exact style. Drapery works particularly well when you want to soften the hard edges of large glass expanses.

Dual Sheer Shades

Boutique Serenity Light Filtering Dual Sheer Shades alternate transparent sheer material with light-filtering fabric bands. Align the bands for privacy. Shift them to let filtered light through. Raise the entire shade for an unobstructed view.

The elegant look suits formal spaces with large windows. Motorized options make operation simple on tall installations. Band heights range from 3" to 4¾" depending on fabric selection. Shades are available in wide widths with fabrics up to 108" or 110" wide.

Light Control That Matters

The best blinds for windows need to handle light effectively, especially on large expanses of glass.

• Light Filtering

  softens harsh sunlight without blocking it. You keep your connection to the outdoors while reducing glare on screens and furniture. Daytime privacy comes from diffused light, though silhouettes may show at night with interior lights on.

• Room Darkening

  blocks most light. Perfect for bedrooms, media rooms, or anywhere you want brightness control throughout the day. Some light may leak around edges, but the room stays comfortably dim.

• Blackout

  eliminates nearly all light. Ideal for shift workers who sleep during the day or home theaters where light control matters. Pair blackout shades with proper mounting to minimize light gaps. (Learn more about creating total darkness in our guide on the blog).

• Sheer and Semi-Sheer

  maintain your view while providing minimal privacy. They work well in private yards or upper floors where neighbors can't see in. Layer them with heavier treatments for flexibility.

Motorization Changes Everything

Large window treatments for large windows can be heavy and awkward to operate manually. Motorization solves that problem.

Battery-powered motors eliminate electrical work. Our rechargeable systems last months between charges. A simple wand control or remote raises and lowers your shades with minimal effort. No cords to tangle or pull.

Smart home integration takes it further. Program your shades to open with sunrise and close at sunset. Control them from your phone when you're away. Connect to Alexa, Google Home, or other systems you already use. Many products now include Bluetooth compatibility for app control.

Motorized blinds for big windows are safer for homes with children and pets. No dangling cords means no entanglement hazards. Cordless operation meets current safety standards while making your life easier.

Measuring Your Large Windows

Accurate measurements ensure your extra wide blinds fit properly and operate smoothly. For detailed instructions, visit our blinds and shades for common window sizes and measuring tips guide.

Inside Mount

Inside mount treatments fit within the window frame. Measure width at the top, middle, and bottom of the opening. Use the narrowest measurement. Measure height from the top of the frame to the sill at the left, center, and right. Use the longest measurement.

Our factory makes deductions for proper fit. Don't subtract anything from your measurements. Inside mount creates a clean, built-in look but requires adequate depth in the frame.

Outside Mount

Outside mount treatments attach to the wall or trim around the window. Measure the width you want to cover, typically extending 2 to 4 inches beyond the frame on each side. Measure height from where you'll mount the headrail to where you want the treatment to end.

The outside mount maximizes light control by covering the entire opening and frame. It works when inside mount depth is insufficient or when you want to make the window appear even larger.

Installation You Can Handle

Most customers install their own blinds for windows. You don't need special skills. A drill, screwdriver, tape measure, and level will get you through most installations in about an hour.

Our installation resources include detailed instructions and videos for each product type. Cellular shades and roller shades typically mount with brackets at the top of the window frame. Drapery hangs from decorative hardware you install first.

Inside mount installations are often simpler because you're working within the frame. Outside mount may require finding studs or using appropriate anchors for your wall type. Instructions specify what hardware you need.

If you run into questions, our in-house experts are available by phone or text. We've helped thousands of customers through installations. No guessing, no stressing.

Styles That Match Your Space

For modern spaces, consider roller shades or cellular shades in clean, minimalist fabrics. Natural textures suit casual, organic interiors. Elegant drapery in rich fabrics elevates formal rooms.

Color choices affect how your space feels. Light neutrals keep rooms bright and airy. Darker shades create drama and block more light. Bold colors or patterns make a statement but should coordinate with your existing decor.

Texture adds visual interest. Subtle weaves, linen-like finishes, and dimensional fabrics catch light beautifully. Smooth, flat materials create a more contemporary look.

Think about how the treatment looks from outside too. Many of our fabrics are white or neutral on the exterior side, maintaining a cohesive appearance from the street.

Energy Efficiency for Large Glass Areas

Large windows lose and gain heat faster than insulated walls. The right window treatments help control energy costs.

Cellular shades

trap air in their honeycomb structure, creating an insulating barrier. Double cell construction provides better insulation than single cell. The R-value can reach up to R-4 with the right materials and construction.

Thermal drapery liners

add insulation while providing light control. Multiple layers of fabric slow heat transfer. Close them on cold nights to reduce heat loss. Keep them closed on hot afternoons to block heat gain.

Even non-insulated treatments

help by blocking direct sunlight. Solar heat gain through glass can significantly increase cooling costs. Shades that reflect or absorb sunlight before it enters the room make a measurable difference.

Motorization and smart home integration

maximize efficiency. Program shades to close during peak sun hours automatically. You save energy without thinking about it.

Maintenance and Care

Window coverings for large windows need regular but simple maintenance.

Dust

cellular shades and roller shades with a microfiber cloth or vacuum with a soft brush attachment. Work from top to bottom. Do this weekly or as needed to prevent buildup.

Spot clean

stains promptly with mild soap and water. Blot rather than rub. Never submerge blinds or shades in water. This applies to all types, including light filtering, blackout, and motorized options. Water immersion damages materials, adhesives, and mechanisms. For deeper cleaning tips, read our easy cleaning hacks for window blinds.

Fabric drapery

can often be removed and dry cleaned. Check care instructions for your specific fabric. Some materials are machine washable on gentle cycles.

Keep mechanisms clean

for smooth operation. A little maintenance prevents bigger problems.
