Rough Opening Considerations
When determining the rough opening size for
interior doors
, there are a few measurements to be taken into consideration. The first action should be to measure the height and width of the existing rough opening. To ensure an accurate measurement, measure several times and take note of the smallest measurements. The width and height may be slightly bigger to allow for shimming and small variations in the framing. The door width should be two inches narrower than the rough opening and the door height should be two inches shorter.
Door Sizing
Interior doors
come in a variety of sizes, but the most common widths for a single door are 24, 28, 30, 32, and 36 inches, while common heights are 79, 81, and 84 inches. It is also possible to buy smaller or larger doors, however they will be slightly more expensive. Generally, a 6 panel design will fit more easily into the rough opening than an 8 panel design.
Shimming
When installing the new door, you may need to add some additional wood in the form of a shim. The reason for this is that it can help make sure that the door fits snugly and securely in the door frame. A shim should be placed in the rough opening before the door, and positioned so that the door is evenly balanced on both sides of the frame. The goal is to make sure that the door is totally flush with the frame when it is finished.
Hardware
Before installing the door, it is important to consider the type of hardware that will be needed. For example, if the door will be a pocket door, special hardware for the pocket mechanism must be installed before the door is mounted. Furthermore, consider the type and style of the door knob and hinges. If heavier doors are being installed, such as those made of steel or a solid wood core, then sturdier hinges and knobs might be required.
