Part 1: Identify Finished Opening
When we talk about Bifolds, it is most important to know what is your Finished Opening Measurement (please measure from side to side, then top to bottom within your door opening). Typically a finished opening for bifolds is complete with sheetrock vs the Rough Openings (RO) for interior doors.
Once we know what your Finished Opening (FO) Dimensions are, we can determine if our standard bifold sizes will work, or if you will need a custom size. If you want an example of what to strive for with standard bifold sizes, and if you discover the FO is exactly 36"W x 80"H, then you could purchase that standard size unit. If you discover the FO is exactly 34"W x 78"H for instance, you would need to order a custom size.

Part 2: Select Your Size & Quantity
Choose your desired width and height dimensions from the options. Enter the quantity of doors you would like to order.

Part 3: Understand the Product
Our pine bifold doors are made with solid stiles(sides) and rails, allowing some room for trimming; however, the tolerance is minimal as too much trimming may affect the integrity of the door. Bifolds include overhead track and hardware for each unit.

Part 4: Need Custom Dimensions?
Standard sizes have minimal tolerance for trimming; avoid cutting too much. If you need special dimensions, contact customer service for a quote.

Commonly Asked Questions
I am replacing an existing door, what dimensions should I use?
If you are looking to replace an existing door, the fastest way to obtain the right dimensions for your new door is to measure your old one. Be sure to note the height, width and depth of the door.
I do not have an existing door to measure from, how do I determine the correct dimensions?
If you do not have an existing door to measure from, following the steps below to get the finished opening size of your doorway:
- Measure the height of the door opening from the sill to the underside of the frame. Obtain this measurement from the left, middle and right sides of the opening.
- Measure the width of the door opening from the inside of the frame to the inside of the frame. Obtain this measurement from the top, middle and bottom of the opening.
- Measure the depth of the door jamb. Typically this dimension is 1 ⅜”, however, for some of our bifold doors, the depth is 1 ⅛”.
- Use the smallest measurement from Step 1 and the smallest measurement from Step 2 (should variations exist) when selecting the dimensions of your new door.
