I suggest following the procedures shown below to ensure that the wall is measured accurately.

  1. A large spirit level is useful for this. The diagonal that connects the corners is what we’re looking for.

Remember to be precise with the opening when you’re picking up one of these doors from the closest hardware store.

Bi-folds are only available in specific sizes at retail locations.

A single door leaf should be at least 28 inches wide for an arrangement of even-numbered doors. Each door should be at least 16 inches wide if you’re using an odd number of doors.

You’ll also need to consider the width of the surrounding frames when calculating the overall bi-fold door thickness.

Aluminum frames are frequently used in these doors. This allows you to build doors with extremely thin and lightweight (but strong) frames.

The metal gives the door support materials like hefty glass, allowing it to bear a great deal of weight.

The door sashes are 2.8 inches wide, and the frames have a total thickness of 3 inches.

Inward or outward opening are options. I recommend installing out-swinging doors if you have enough space outside.
