Select an item below for a quick check, or enter custom dimensions to test any window opening.
This calculator determines if furniture and large items can fit through window openings — a common solution for high-rise apartments, narrow staircases, and tight-access deliveries. We account for window opening dimensions, removal of the sash or frame, exterior clearance for hoisting, and safety considerations for above-ground floors.

Standard double-hung windows are 24–36" wide × 36–60" tall. The usable opening (sash up) is only half the total height. Casement windows open wider. Picture windows don't open at all. Sliding glass doors (60–72" wide × 80" tall) offer the largest residential openings.
On double-hung and casement windows, the sash can usually be removed (tilt-in or unscrew the tracks). This converts the half-opening into the full frame opening. Some older windows require a professional to remove the sash. Always reinstall the sash after the move.
Professional movers use a block-and-tackle or motorized hoist attached to the window frame or a rooftop anchor. The furniture is wrapped in moving blankets, secured with straps, and lifted from ground level to the window. Cost ranges from $300–$1,000+ depending on floor height and item weight.
With professional movers, yes. Never attempt DIY hoisting above the first floor — the risk of injury and property damage is extreme. Professional hoisting companies carry liability insurance and use rated rigging equipment. Always clear the area below the window before any hoisting operation.
