Standard commercial door frames typically come in widths ranging from 28 to 48 inches and heights of 80, 84, or 96 inches to accommodate common door sizes. The most common frame size is 36 inches wide by 84 inches tall, designed to fit standard 3-foot by 7-foot doors. Frames are also available in custom sizes to fit specific architectural requirements or oversized openings. These frames are built to meet commercial building codes and accommodate various door types, including hollow metal, wood, and glass doors.
What are the most common widths for commercial door frames?
The most common widths for commercial door frames range from 28 inches to 48 inches, with 36 inches being the standard and most widely used size.

What size frame fits a standard commercial door?
A standard commercial door typically measures 36 inches wide by 84 inches tall, so the corresponding door frame is sized slightly larger—usually about 38 inches wide by 86 inches tall—to allow for proper clearance, installation, and hardware. This ensures the door fits securely and operates smoothly within the frame.
Do commercial door frames differ by door material?
Commercial door frames generally follow standard size ranges regardless of door material, whether steel, wood, aluminum, or fiberglass. However, frame design, thickness, and finish can vary based on the material to ensure proper fit, durability, and compatibility with the door type. For example, steel frames are common for hollow metal doors, while wood frames may pair with wood doors, and aluminum frames are typical for storefront or glass doors.
Why is knowing the standard frame size important?
Knowing the standard frame size is important because it ensures proper compatibility between the door and frame, simplifies installation, and helps meet building codes and accessibility standards. Using standard sizes reduces costly custom adjustments, speeds up project timelines, and guarantees that hardware and accessories fit correctly for optimal door performance and safety.
Are there any specific regulations or codes for commercial door frames?
Yes, commercial door frames must comply with specific building codes and regulations to ensure safety, accessibility, and performance. Key standards include:
- ADA (Americans with Disabilities Act) requirements, which dictate minimum clear widths and hardware accessibility for doorways to accommodate people with disabilities.
- IBC (International Building Code) guidelines, covering fire ratings, egress dimensions, and structural requirements for door frames.
- NFPA (National Fire Protection Association) standards, especially NFPA 80, which regulates fire door assemblies, including frames, to ensure fire resistance and safe evacuation.
- Local building codes, which may have additional specifications depending on jurisdiction.
Compliance with these regulations is crucial for legal approval, occupant safety, and insurance purposes.
