When planning a commercial door installation, many people ask: what is standard door size, and can it be used in a non-standard opening? The answer is yes, and in most cases, it’s the smarter approach. At CDF Distributors, we strongly recommend using standard size doors instead of ordering fully custom products whenever possible. With the right adjustments, standard doors can fit a wide variety of openings while delivering significant cost and scheduling benefits.
What Is a Standard Door Size?
In commercial construction, door sizes are standardized to simplify manufacturing, installation, and replacement. Both metal and wood doors typically come in a 1-3/4” thickness and are produced in a range of common dimensions.
Standard Commercial Door Width Options
- 2'0" (24")
- 2'6" (30")
- 2'8" (32")
- 3'0" (36") - the most popular standard commercial door width
- 3'4" (40")
- 3'6" (42")
- 3'8" (44")
- 4'0" (48")
Average Commercial Door Height Options
- 6'8" (80") - great for older buildings
- 7'0" (84") -
If you are buying a door for the first time, terms like door handing and door swing direction can feel confusing. These details matter more than most people expect. Choosing the wrong swing can lead to installation problems, code issues, or a door that does not function the way you need it to.
Understanding how commercial door swing works helps ensure your door opens correctly, meets building requirements, and supports safe movement through the space. This guide breaks down the basics so you can confidently choose the right direction for your door.
Door Handing vs Door Swing
Door handing and door swing direction are closely related and often used together, but they describe slightly different parts of how a door operates. Door handing refers to which side the hinges are on when you are standing on the outside of the door, while door swing describes the direction the door opens from that same position.
You may also hear terms like swing side, hinge side, or see diagrams in a commercial
Before you measure a door rough opening, there are several critical decisions that must be made first — and skipping this step is one of the most common causes of ordering mistakes in commercial door projects.
In this video from CDF Distributors, we walk through what needs to be determined before you ever pick up a tape measure so your door system is specified correctly the first time.
Commercial Door Installation Planning Checklist
Before measuring a commercial door rough opening, contractors should first determine the door type, fire rating requirements, door swing direction, frame type, hardware requirements, and building code considerations. Proper commercial door planning helps prevent ordering errors, installation delays, failed inspections, and costly project rework.
- Determine if the opening requires a commercial steel door or wood door
- Confirm fire-rated door requirements
- Select single door or double door configuration
- Verify door swing direction and handing
- Choose the correct
What steps do you take to prepare for commercial door installation? Setting up tools and taking measurements are important, but we recommend starting a little earlier to ensure a smooth and easy installation process. Proper preparation for commercial door installation starts before your door packages are delivered to the jobsite. In fact, it often begins before you even place an order.

Where Does Preparing for Installation Begin?
As mentioned above, preparing for commercial door installation starts before ordering doors. The first step is to determine the type of door, frame, and hardware your project requires. This applies whether you are planning warehouse door installation, commercial glass door installation, or commercial metal door installation. You will need to consider how much traffic the door will see. High-traffic openings often require heavier-duty doors and hardware.
Next, determine the door size
Installing a commercial door might seem straightforward, but the details can quickly add up. The type of door, frame, and opening all play a role in how smooth—or frustrating—the installation process will be.
Choosing the right setup from the start can save time, reduce labor, and help avoid costly mistakes on-site. Here’s a practical look at what to check before installation, which doors are easiest to work with, and what can slow things down.
Start With the Basics
Before beginning any commercial door installation, a few simple checks can prevent major issues later:
-
Make sure the door and frame size match your rough opening
-
Confirm whether you're working with drywall or masonry.
-
Choose the right frame type for the application, will it butt up or wrap?
-
Check that hardware is properly prepped
-
Have the correct tools and anchors ready
-
Review fire rating requirements if applicable
Skipping any of these steps can lead to delays, rework, or improper
Choosing the wrong door frame can lead to expensive delays, failed inspections, and major rework on the jobsite—but it doesn’t have to. In this video, we break down how to choose the right commercial door frame so you can avoid costly mistakes before they happen.
Quick Answer: How Do You Choose the Right Commercial Door Frame?
Choosing the right commercial door frame depends on the wall construction, opening type, fire rating requirements, and installation method. The two most common commercial door frame types are welded frames and knockdown (KD) frames. Welded door frames are typically used for masonry walls, exterior openings, and high-abuse applications, while knockdown door frames are commonly used for drywall construction and interior commercial openings. Selecting the correct hollow metal door frame helps ensure proper installation, code compliance, long-term durability, and accurate door operation.
