What is a Garage Door Rough Opening?

A garage door rough opening, often referred to as the RO, is the area in the framework of the garage where the door will be installed. It is the opening that is created in the wall of the garage to accommodate the garage door. RO sizes can vary greatly depending on factors such as the size of the garage, specific needs of the homeowner, and local building codes.

What Are the Rough Opening Dimensions?

Garage door rough opening dimensions are typically measured in feet and inches. The width of the RO is usually determined by the width of the garage itself, and the height is determined based on the size of the door being installed

How to Determine The Rough Opening Size

The RO size should be large enough to accommodate the garage door's overall dimensions, including the door panels, tracks, and any necessary hardware

The following steps can assist in determining the RO size for a garage door:

Step 1: Measure the width of the garage:
Determine the clear width of the garage space where the door will be installed. This measurement should not include any obstructions such as walls, posts, or light fixtures.

Step 2: Determine the height of the garage door:
Measure the desired height of the garage door from the floor to the top of the opening. This measurement should consider the height of vehicles that will be entering and exiting the garage, as well as any clearance requirements for the door's operation.

Step 3: Check local building codes:
Refer to local building codes or consult with a building professional to determine any specific requirements or restrictions related to garage door RO sizes within the local jurisdiction.

Step 4: Add the necessary clearances:
Allow for additional clearance around the perimeter of the door to ensure smooth operation and proper installation. Typically, 2 to 3 inches of clearance is recommended on both sides of the door, and 4 to 6 inches of clearance is recommended above the door.

Step 5: Calculate the rough opening dimensions:
To determine the width of the RO, add the door width and 2- 6 inches of clearance on each side. To calculate the height of the RO, add the door height and 4-6 inches of clearance above the door.

What is the Standard Rough Opening For A Garage Door?

Standard RO sizes vary based on different factors. In the United States, a standard RO for a single-car garage door is typically 9 feet wide and 7 feet high. For a double-car garage door, the standard RO is usually 16 feet wide and 7 feet high.

It's important to note that these are just general guidelines, and the actual RO size may differ depending on the specific door chosen and the space available. Always refer to the manufacturer's instructions or consult with a qualified professional for accurate sizing and installation.
