Which Windows Are Large Enough for Furniture? A Size Guide
Window Size Varies Dramatically
A bathroom window might be 24 × 16 inches — barely big enough for your arm. A living room picture window might be 72 × 48 inches — wide enough for a sectional. Knowing which windows in your home are large enough for furniture delivery opens up options that the door route may not provide.
Window Types Ranked by Furniture-Delivery Potential
1. Sliding Glass Doors / Patio Doors (Best)
- Clear opening: 30–48 inches wide × 76–80 inches tall
- Furniture delivery rating: Excellent. Nearly as good as a standard door with more height.
- Notes: The opening is only half the total door width (one panel slides behind the other). Remove the screen first.
2. Large Double-Hung or Picture Windows
- Clear opening (sashes removed): 34–46 inches wide × 50–60 inches tall
- Furniture delivery rating: Good. Wide enough for most couches and mattresses on their side.
- Notes: Sash removal required for maximum opening. See our window extraction guide.
3. Paired Casement Windows
- Clear opening (both sashes removed): 40–52 inches wide × 44–52 inches tall
- Furniture delivery rating: Good width but limited height. Furniture must be tilted or loaded horizontally.
- Notes: The mullion (center post) between paired casements may need to be removed for full clearance — this is a professional job.
4. Standard Double-Hung (Single)
- Clear opening (sash removed): 26–34 inches wide × 50–60 inches tall
- Furniture delivery rating: Moderate. Works for mattresses on edge and narrow furniture. Check mattress fit.
- Notes: Width is the limiting factor. A 30-inch wide window opening won't pass a 34-inch wide couch.
5. Single Casement
- Clear opening: 20–26 inches wide × 44–52 inches tall
- Furniture delivery rating: Poor. Only small items and narrow furniture.
6. Awning / Hopper Windows
- Clear opening: 24–48 inches wide × 12–24 inches tall
- Furniture delivery rating: Very poor. Opening height is too small for almost all furniture.
7. Basement Egress Windows
- Clear opening (code minimum): 20 × 24 inches (5.7 sq ft minimum area)
- Furniture delivery rating: Limited. Some mattresses and small furniture fit through larger egress windows. Often the only option for basement apartments.
Minimum Window Size for Common Items
- Queen mattress on edge: Needs ≈ 12" × 60" opening (width × height) — fits most double-hung windows
- King mattress on edge: Needs ≈ 12" × 76" opening — too tall for most windows. May need folding (foam only) or a door route.
- Couch on its side: Needs ≈ 34" × 34" opening — requires large windows or patio doors
- Dresser: Needs ≈ 20" × 36" opening — fits most double-hung windows
- Desk: Varies widely — disassemble if possible before attempting window delivery
How to Evaluate Your Windows
- Walk through every room and identify the largest operable window
- Measure the clear opening (with sash removed or open)
- Note the floor height (ground floor, 2nd floor, etc.) — this determines delivery method
- Check exterior access: is there clear ground below the window for a team to work?
- Enter dimensions into the window fit calculator
FAQ
What's the easiest window type for furniture delivery?
Sliding glass doors / patio doors. They provide the largest opening, are ground-level (no hoisting), and the item slides in horizontally. If your apartment has a patio door and you're struggling with narrow hallways, the patio door may be your answer.
Can furniture fit through a bay window?
Bay windows have angled side panels and a center panel. The center panel (if it's a picture window) can be removed by a professional for a large opening. The angled sides are too small for most furniture. The bay window structure itself is structural — don't remove the frame, only the glass panel.
