French Door Terminology

When shopping for French doors, you’ll encounter some important terminology related to size:

Brick Opening Size: The dimensions of the actual opening in the wall where the door unit will be installed. Brick opening sizes must be slightly larger than the frame size.
Rough Opening Size: The brick opening size of about 2.5cm added to the width and height to account for shims during installation.
Frame Size: The overall exterior dimensions of the pre-hung door unit, including one French door panel on each side and the frame.
Door Panel Size: The width and height of a single French door panel or side. Double this dimension for the total width of a typical double French door.

How to Measure for French Doors in CM

Accurately measuring your opening is crucial for getting a properly fitting set of French doors. Follow these steps:

Gather Tools

You’ll need a metal tape measure, a pencil, paper, and a helper.

Measure Width

Measure across the top, middle, and bottom of the opening. Use the smallest measurement.

Measure Height

Measure from floor to top on the left and right sides. Use the largest measurement.

Determine Rough Opening Size

Add 2.5cm to the width and height measurements for your rough opening size.

Compare to French Door Sizes

Use your rough opening size to pick appropriately sized doors.

Factors That Limit French Door Sizes

While French doors can be pretty large, there are some practical limitations on maximum sizes:

Wind load – Very wide doors are more prone to bowing or damage from wind pressure. 190cm is generally the maximum safe width.
Hinge strength – Standard hinges can only support so much weight before sagging or breaking. Wider/taller doors may require heavy-duty hinges.
Hardware limits – Standard handles and lock components have size limitations. Oversized doors may require custom hardware.
Door panel weight – Larger glass panels or solid wood doors get very heavy. Consider width limits to avoid overly heavy panels.
Aesthetics – Doors that are too large can be overwhelming and out of proportion. Carefully consider the overall look.

Is the Size of a French Door in CM Related to Its Weight?

When considering the installation of French doors, it’s important to factor in the french door weight measurement. The size of a French door in centimeters can be directly related to its weight. It’s critical to know the door’s weight when planning for installation or making any necessary structural adjustments.
