Door Handing Explained: A Beginner's Guide to Door Swing Direction

Order a door in the wrong “hand” and it arrives hinged on the wrong side — opening into a wall, blocking a hallway, or clashing with a light switch. Handing can't be flipped after manufacturing on factory-built aluminum and steel doors, so it's worth sixty seconds to get it right. Here's the whole system, in plain English.

What is door handing?

Door handing describes which side the hinges are on and which way the door swings, from one agreed-upon viewpoint. In residential ordering, that viewpoint is simple: stand OUTSIDE, facing the door. Hinges on the right make it a right-hand door; hinges on the left make it a left-hand door. If it opens away from you (into the house), it's an inswing; if it opens toward you, it's an outswing.

How to tell if a door is left-handed or right-handed

Stand outside the doorway, facing the door, and check the hinges. Right side: right-hand. Left side: left-hand. Then note the swing — away from you is inswing, toward you is outswing. That's the entire test. If the door isn't installed yet, picture yourself standing where the doorbell would be.

Inswing vs. outswing: which should a front door be?

Most American front doors are inswing — they open into the home, keep hinges on the interior side, and clear porches and storm screens. Outswing doors trade that for a tighter weather seal against wind-driven rain and zero floor space lost inside, which is why you see them on patios, pool baths, and coastal homes. Neither is “better” — the right answer comes from your floor plan, your porch depth, and what's beside the opening inside.

A quick heads-up on commercial terminology

Commercial and institutional specs sometimes determine handing from the opposite side of the opening, and use terms like “left hand reverse (LHR).” If you're comparing a commercial spec sheet to a residential quote, the same physical door can carry two different labels. The fix is easy: describe the door in plain words — “standing outside, hinges on the right, opens in” — or just send us a photo. We confirm handing on every order before production.

Double and French doors: the active leaf

On a double or French door, one panel does the daily work — the active leaf, with the lever and lock — while the inactive leaf stays bolted until you release it to open the full width. Handing is named by the active leaf using the same outside-facing rule: active panel hinged on the right means right-hand active.

Sidelites don't change anything

Sidelites — the fixed glass panels beside an entry door — change the look and the light, not the handing. A right-hand door is right-hand whether it has zero, one, or two sidelites.

Codes, egress, and common sense

For houses, building codes generally leave front-door swing to you. Commercial exits are different: egress doors often must swing in the direction of travel. If your project is a business storefront, office, or anything with an occupancy requirement, confirm swing direction with your local code office or your GC before ordering.

How to order the right swing from us

Three ways, easiest first: send a photo or short video of the opening from outside; or tell us in plain words (“standing outside, I want hinges on the left, opening in”); or use the formal term if you know it (“left-hand inswing”). We restate the handing on every quote for casement, French, pivot, and entry doors — you approve it before anything goes to production.
