Step 1
If you are dealing with a larger 4DR door, the opening size could be up to 72" x 81". Keep in mind that bifold doors are designed to be slightly smaller for an optimal fit.
For example,
If the nominal size of your door is 36" x 80",the actual size is typically 35 1/2" x 79".
To accommodate this door, the opening should measure up to 36" x 81
Step 2
Each bifold panel measures 79" in height and 17 3/4" in width, resulting in a total width of 35 1/2".
Step 3
Each bifold panel measures 79" in height and 17 3/4" in width, resulting in a total width of 35 1/2".
Step 4
For a space with dimensions of 72" x 81", two bifolds, each measuring 35 1/2" x 79", would provide a perfect fit.
Step 5
Understanding these sizing details ensures a smooth and aesthetically pleasing installation.
Please note that the actual steps may vary depending on the specific situation, and it's always important to consult the manufacturer's instructions and guidelines for accurate sizing and installation information.
