What is a Double Door Rough Opening?

A double door rough opening is the opening in the wall where double doors will be installed. It is important to get the rough opening size right so that the doors fit snugly and there are no gaps.

The rough opening size will vary depending on the size of the doors and the type of hinges and latches that are used.

The general rule of thumb is to add 2 inches to the width of each door and 2.5 inches to the height of each door. If you are installing two 30-inch wide double doors, the rough opening size would be 62 inches wide and 65 inches high.

The rough opening should also be level and plumb. This means that the top and bottom of the opening should be level, and the sides of the opening should be straight.

If the rough opening is not level and plumb, the doors may not fit properly or they may not open and close smoothly.

Once the rough opening is framed and ready, the door frames can be installed. The door frames will be attached to the rough opening using screws or nails. Once the door frames are installed, the doors can be hung.

Here are some important things to keep in mind when framing a double door rough opening:

  1. Make sure the opening is level and plumb.
  2. Use sturdy materials to frame the opening, such as 2×4 or 2×6 lumber.
  3. Insulate the opening with fiberglass or foam insulation.
  4. Weatherproof the opening with caulk or sealant.

Why is it Important to Get the Rough Opening Size Right?

Precise measurements for your double door rough opening are crucial for several reasons:

  1. Proper Functionality: An accurately measured rough opening ensures that your double doors will operate smoothly and efficiently. A poorly sized opening can lead to doors that don’t close properly or have gaps, making them less energy-efficient.
  2. Aesthetics: The size of the rough opening significantly affects the visual appeal of your doors. A well-fitted opening contributes to an attractive, symmetrical appearance, while an ill-fitted one can be an eyesore.
  3. Structural Integrity: A correctly sized rough opening maintains the structural integrity of your wall, ensuring it can support the doors’ weight and withstand environmental stresses.
  4. Building Codes: Building codes often dictate minimum requirements for door openings to ensure safety and accessibility, making it essential to comply with these regulations.
