When ordering a commercial door, one of the most important details is door swing direction. At Doors Unlimited Inc., we frequently help customers clarify door handing to ensure the door fits properly, functions correctly, and meets code requirements.
This guide explains what door swing direction is, how to determine it, and why it matters for your commercial project.
What Is Door Swing Direction?
Door swing direction (also called handing) describes:
- Which way the door opens (toward or away from you)
- Which side the hinges are on
Commercial doors are typically classified as:
- Left-Hand (LH)
- Right-Hand (RH)
- Left-Hand Reverse (LHR)
- Right-Hand Reverse (RHR)
The term “reverse” usually applies to exterior doors and indicates that the door opens outward instead of inward.

How to Determine Door Swing Direction
To identify the correct swing:
- Stand on the side where the door opens toward you
- Look at the hinges
- Hinges on the left → Left-hand
- Hinges on the right → Right-hand
If the door opens away from you, it is considered a reverse swing.
This simple method helps eliminate confusion and ensures accurate ordering.
Why Door Swing Direction Is Important
Proper Fit and Installation
A door with the wrong swing may not fit the opening or align properly with the frame, hardware, or surrounding walls. This can lead to delays and additional costs.
Building Codes and Regulations
Many commercial building codes regulate door swing direction, especially for:
- Exit and egress doors
- Fire-rated assemblies
- High-occupancy areas
Incorrect swing direction can result in failed inspections or required replacements.
Safety and Accessibility
Door swing affects:
- Safe emergency exits
- ADA-required clearances
- Ease of movement in high-traffic areas
Correct handing helps ensure doors operate safely and efficiently in daily use.
Hardware Compatibility
Certain hardware such as panic devices, door closers, and electric strikes depends on door swing direction. Choosing the wrong handing can limit hardware options or require reordering.
Common Door Swing Mistakes
Some of the most common issues include:
- Assuming all doors swing the same way
- Confusing interior and exterior handing
- Forgetting to account for wall space, equipment, or traffic flow
- Not verifying swing direction before ordering
Taking the time to confirm swing direction upfront can prevent costly errors later.
