Select the right door for you is easy! 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.
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.
