Offset Hinges and Other Two-Inch Wins for Wheelchair Clearance
A standard 30-inch door leaves about 27 inches of actual clear opening. A pair of $25 hinges gives back two of them, no drywall dust required.
Wheelchair clearance is measured in inches, and the most expensive inch is the one that requires reframing a wall. Before you price a widened doorway, measure what you actually have. A door’s nominal width is the slab; the usable opening is the slab width minus the thickness of the door standing in the way, minus the stop moulding. On a 30-inch door that math lands around 27 inches, and 32 inches of clear width is what most chairs want. A handful of hardware swaps can close much of that gap in an afternoon.
Where the inches go
With standard butt hinges, an open door pivots inside the jamb, so the 1-3/8-inch slab and the hinge barrel both sit in the opening. Swing-clear hinges have an L-shaped leaf that moves the pivot point out past the casing; when the door is open to 90 degrees, it clears the opening completely. That recovers roughly 1-1/2 to 2 inches. The door stop on the strike side eats another 1/2 inch, and a raised threshold is a speed bump for small front casters. Attack all three.
Measure the real clear width
Open the door to 90 degrees and measure from the face of the door to the strike-side stop. That is your baseline. Now measure from the hinge-side stop to the strike-side stop; that is what swing-clear hinges will get you. If the second number is 31-1/2 inches or more, this project gets you there without a saw. Count the hinges and measure them corner to corner: residential doors use 3-1/2-inch hinges, heavier doors 4-inch.
Swap hinges one at a time
Leave the door hanging. Remove the top hinge’s screws from both leaves, slide it out, and set the swing-clear hinge in the same mortises. The offset leaf sits on the jamb face rather than in the rabbet, so it may need a shallow relief chiseled into the casing edge; mark it, score with a utility knife, and pare to depth with a sharp chisel. Drive the screws with the drill on low clutch, then finish by hand so you do not strip the jamb. Repeat for the bottom hinge, then the middle.
Fix stripped holes properly
Old jamb screw holes are often chewed out. Dip three or four toothpicks in wood glue, pack them into the hole, snap them flush, and wait 20 minutes before driving the new screw. For the hinge screw closest to the drywall on each jamb leaf, use a 2-1/2-inch screw that reaches the framing; that one screw carries most of the door’s weight.
Remove or shave the strike-side stop
If the stop is applied moulding, score the paint line and pry it off the strike jamb; the door now closes against the latch alone, which is fine for interior doors. If the stop is milled into the jamb, cut it back flush with an oscillating multi-tool and sand. Fill nail holes and touch up paint. That is another 1/2 inch of clear passage.
Replace the knob and flatten the threshold
Swap round knobs for lever handles; they open with a closed fist or an elbow and cost $20 to $40. Confirm the backset, 2-3/8 or 2-3/4 inches, before buying. Then check the floor transition: anything above 1/2 inch needs a beveled aluminum threshold ramp, screwed down, not taped. Anything above 1/4 inch should be beveled 1:2.
Swing-clear hinges push the door about an inch farther from the jamb when open, which can make it collide with a wall-mounted light switch, a towel bar, or a toilet that used to be clear. Swing the door fully before you drive the last screws. Fire-rated doors to an attached garage must keep a stop and a closer; check with your building department before removing anything from that one.
You do not always need a wider doorway. Sometimes you just need the door to get out of the way.
Next steps if two inches is not enough
If the swing-clear math still leaves you under 32 inches, the next stops are a 34-inch pre-hung door in the same rough opening, if the framing allows, or a pocket door that removes the slab from the equation entirely. Both are weekend projects with drywall repair. Do the hinge swap first anyway; it costs an afternoon, and it tells you exactly how much more you need.
