Door swing direction is one of the most common points of confusion when ordering a commercial door. It is also one of the easiest things to get right once you know what to look for.
The challenge is that small mistakes can lead to ordering the wrong door, delaying installation, or even failing inspection. Understanding door swing direction early makes the entire ordering process smoother.
What Is Door Swing Direction?
Door swing direction refers to the side of the hinges and the direction the door opens. In commercial doors, this is classified as left-hand (LH), right-hand (RH), left-hand reverse (LHR), or right-hand reverse (RHR).
Once you understand how these are determined, identifying the correct swing becomes straightforward.
How to Determine Door Swing Direction
To determine the door swing direction, stand on the hinge side of the door. If it swings left, it is left-hand. If it swings right, it is right-hand.
-
Stand on the hinge side of the door
-
If the door swings to your left, it is left-hand
-
If it swings to your right, it is right-hand
Most confusion comes from standing on the wrong side or trying to overcomplicate the process. When you are on the hinge side, the direction is easy to identify.
Using a Commercial Door Swing Chart
A commercial door swing chart is a quick way to confirm what you are seeing.
It visually maps hinge position and swing direction into the four standard configurations: LH, RH, LHR, and RHR. Matching your door to a chart helps eliminate guesswork and ensures accuracy before ordering.
Egress Door Swing Direction and Code Requirements
In commercial buildings, door swing direction is sometimes dictated by code.
Egress doors, which are part of an exit path, often must swing in the direction of travel. This allows for safe and efficient exit during an emergency.
Depending on the building type and occupancy, this may be required. That is why door swing direction should always be considered alongside how the opening will be used.
Where Door Swing Mistakes Happen
Most door swing mistakes happen when details are left open to interpretation during ordering.
Common issues include:
-
Looking at the door from the wrong side
-
Mixing up inswing and outswing
-
Not accounting for egress requirements
-
Miscommunication between teams or suppliers
These are small errors, but they can lead to incorrect orders and delays.
Is Door Swing Direction Important When Ordering a Commercial Door?
Yes. Door swing direction determines how the door functions within the opening and must be correct for proper installation, code compliance, and overall performance. Ordering the wrong swing can lead to delays, rework, and additional costs.
Why the Ordering Process Matters More Than You Think
Most door swing issues do not come from the door itself. They come from how the order is placed.
Traditional ordering methods rely on back-and-forth communication, where details like door swing direction are interpreted instead of clearly defined.
