French Door Terminology

  • 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.

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.
