Window Types & Sizes: Which Windows Work for Furniture Moves
When furniture will not fit through the door or up the stairs, a window is often the next option — especially in high-rise apartments and older homes with tight access. But not all windows open wide enough for furniture. The type of window, its standard size, and whether the sash can be removed determine whether this route is viable. This guide covers every residential window type and what you can realistically pass through each one.
Check if your furniture fits through the window before moving day.
Common Residential Window Types
| Window Type | Typical Width | Typical Height | Usable Opening for Furniture |
|---|---|---|---|
| Single-hung | 24 - 36 inches | 36 - 60 inches | Only bottom sash opens — opening is half the total height (18 - 30 inches) |
| Double-hung | 24 - 36 inches | 36 - 60 inches | Both sashes slide — but opening is still half the height unless a sash is removed |
| Casement (crank-out) | 24 - 36 inches | 36 - 72 inches | Entire sash swings open — full frame opening is usable (best type for furniture) |
| Sliding (horizontal) | 36 - 72 inches | 36 - 60 inches | One panel slides — opening is half the frame width (18 - 36 inches) |
| Bay / bow | 60 - 120 inches total | 36 - 60 inches | Only flanking casements or double-hungs open — center panel is fixed |
| Picture | 24 - 96 inches | 24 - 72 inches | Does not open at all — no usable opening for furniture |
| Awning | 24 - 48 inches | 18 - 36 inches | Hinged at top, opens outward — small opening, rarely useful for furniture |
Standard Window Dimensions by Room
| Room | Typical Window Width | Typical Window Height | Notes |
|---|---|---|---|
| Living room | 36 - 48 inches | 48 - 60 inches | Largest standard windows; best candidates for furniture moves |
| Bedroom | 30 - 36 inches | 48 - 60 inches | Must meet egress code (see below) — usually large enough for a person |
| Bathroom | 24 - 30 inches | 36 - 48 inches | Smaller and often obscured glass — rarely useful for furniture |
| Kitchen | 24 - 36 inches | 36 - 48 inches | Often above the sink; limited height clearance below the sill |
| Basement | 30 - 36 inches | 18 - 24 inches | Egress windows are larger (see code below); standard basement windows are too small |
Clear Opening vs Frame Size
Just like doors, the window frame size is not the same as the usable opening. The frame includes the casing, stops, and tracks that hold the sash in place. On a double-hung window, the clear opening when the bottom sash is raised is typically the full frame width minus 0.5 to 1 inch on each side (for the tracks) and only half the frame height. Removing the bottom sash eliminates the height restriction and gives you the full frame opening minus the track width. On casement windows, the clear opening with the sash cranked fully open is the full frame dimensions minus the hinge hardware — usually within 0.5 to 1 inch of the frame size on each edge.
Egress Window Code Requirements
Building codes require bedrooms to have at least one egress window large enough for a person to escape in a fire. The IRC (International Residential Code) Section R310.2 requires a minimum net clear opening of 5.7 square feet, with a minimum width of 20 inches and minimum height of 24 inches. The maximum sill height is 44 inches from the floor. This means every code-compliant bedroom window is at least 20 inches wide and 24 inches tall when fully open — large enough for many furniture items when tilted or with the sash removed.
Which Window Types Allow Sash Removal
- Double-hung (tilt-in): Modern double-hung windows have tilt-in sashes. Pull the tilt latches inward, tilt the sash to 90 degrees, then lift it out of the tracks. This converts the half-opening into the full frame opening.
- Double-hung (older/non-tilt): Older windows require removing the interior stop molding (a thin strip of wood holding the sash in the track). Pry it off carefully with a putty knife, then slide the sash out.
- Casement: Casement sashes are attached to the frame with hinges. To remove, open the sash fully, disconnect the crank arm (usually a clip or pin), then unscrew the hinges. This requires a screwdriver and takes 10 to 15 minutes.
- Sliding: One panel is typically fixed and one slides. The sliding panel can usually be lifted up into the top track and swung out at the bottom. The fixed panel may require removing interior stops.
- Picture / fixed: Cannot be removed without breaking the seal. Not an option for furniture access.
Furniture That Can Fit Through Windows
| Furniture Item | Typical Dimensions | Minimum Window Opening Needed | Notes |
|---|---|---|---|
| Mattress (twin) | 38" × 75" × 8-10" | 24" × 40" (tilted) | Compresses slightly; fits through most egress windows |
| Mattress (queen) | 60" × 80" × 10-14" | 36" × 62" (tilted) | Needs a large casement or sash-removed double-hung |
| Couch (3-seat) | 84" × 35" × 33" | 36" × 35" | Must be hoisted vertically; professional rigging required above 1st floor |
| Dresser | 36-60" × 18" × 30-36" | 24" × 38" | Smaller dressers fit through most bedroom windows |
| Desk | 48-60" × 24-30" × 30" | 30" × 32" | Remove legs or drawers to reduce dimensions |
| Bookshelf | 30-36" × 12" × 72" | 14" × 32" (on side) | Thin profile — fits through most windows when turned sideways |
Frequently Asked Questions
What type of window is best for moving furniture through?
Casement windows are the best because the entire sash swings outward, giving you the full frame opening. A 36-inch casement provides about 35 inches of clear width. Double-hung windows are second best if you remove the sash — otherwise, the opening is only half the frame height.
What size are standard residential windows?
Standard double-hung windows are 24 to 36 inches wide and 36 to 60 inches tall. Casement windows range from 24 to 36 inches wide and 36 to 72 inches tall. Sliding windows can be 36 to 72 inches wide. The usable opening depends on the type — casements open fully, while double-hung and sliding windows open to only half their frame size.
Can I remove the window sash to get more space?
Yes, on most double-hung, casement, and sliding windows. Modern tilt-in double-hung sashes take about 2 minutes to remove. Older windows require removing the stop molding (10 to 15 minutes). Casement sash removal takes 10 to 15 minutes with a screwdriver. This typically doubles the usable opening height on double-hung windows.
Do picture windows open for furniture?
No. Picture windows are fixed glass — they do not open at all. They cannot be used for furniture access without replacing or cutting the window, which is not practical. If the room only has picture windows, you must use the door, or check other rooms for operable windows.
