What to Measure

1Window opening width and height with the sash fully open — this is the usable clearance, not the overall window frame size.
2Window sill height from the floor — determines your loading angle and whether you need exterior rigging.
3Whether the window sash can be removed — removing the sash typically adds 2–4 inches of clearance on each side.
4Exterior clearance and floor height — hoisting from ground level requires rigging equipment and clear access below the window.

Common Mistakes to Avoid

Measuring the window frame instead of the actual opening — the usable opening is 2–4 inches smaller than the frame dimensions.
Forgetting that double-hung windows only open halfway unless the sash is removed.
Not checking if the building allows window deliveries — many apartment buildings prohibit hoisting without prior approval and insurance.
Assuming any window is large enough — standard double-hung windows (24–36" wide) are much smaller than most furniture pieces.

Frequently Asked Questions

What size are standard residential windows?

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.

Can I remove the window to get more clearance?

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.

How does furniture hoisting through a window work?

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.

Is it safe to hoist furniture through a window?

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.
