How do I size bi-fold closet doors? How do I size bi-fold closet doors?
To size bi fold closet doors, you will need to measure the width and height of the door opening. Measure both the top and bottom of the door jamb. If the numbers aren't the same (which is common) go with the smaller number. Many bi-fold doors come in standard sizes and can be ordered directly from the company. If a specialty door must be made, the sizing allowance for the specific hardware will be designated by the company. Different series have different hardware. Subtract the hardware dimensions from the height. For french door style bi-folds, divide the width in half for each door size and subtract hardware from the height.
