The size of the bifold is based on the Opening size. The bifold is always undersized.
Example: A 35” x 80” bifold means the bifold Fits to the opening of 35” x 80”
The most popular standard sizes for a bifold are as below
---2DR bifold are 18", 20", 24", 28", ,30", ,32", 36",
---4DR bifold are 48", 60", 72",
any size from 18" up to 36" could be made by Custome orders.
What is the best size of a bifold door for an opening of 76"?
any sizes more than 36" up to 48", could be ordered on Solid core bi-fold. since the maximum door width on each panel can't exceed 24".
1-first solution: less expensive
Make the opening narrower to 72" by adding a piece of 2" wood on each side and taking advantage of a standard door 72 x 80 with a reasonable price
2-Second Solution: more expensive
Order a custom MDF 4DR bifold door to fit the opening of 76" (it costs 5 to 6 times more vs hollow core)
