Rough Dimensions of Interior Doors: What You Need to Know
In the process of designing a house, establishing the rough dimensions of your interior doors is an essential step. The size of the doors needs to be taken into account when designing the walls and framing of the home. Establishing your interior door dimensions early on will help to ensure that everything fits together properly. Furthermore, it is important to consider different door mechanisms during this step, as some mechanisms require more space than others.
Standard Door Dimensions
Standard door dimensions for interior doors in many North American homes are 6' 8” tall, and come in widths ranging from 24” to 36”. These dimensions depend on the size and layout of the room, and should certainly be taken into account when selecting the doors. It is also important to bear in mind the dimensions of the hardware, particularly if an older home is being renovated. Depending on the individual preference, doors may also be taller or shorter than the standard dimensions.
Other Considerations
Not all aspects of door dimensions are determined by design alone. Ventilation is an important factor to consider, as many current building codes require some form of ventilation from within the home. This can be achieved by installing a louvered door, or by specifying a certain dimension of air space when selecting the interior doors . It is also important to take into account the thickness of the door when shopping for pre-hung doors. Depending on the type of door being installed, the rough opening may require additional height or width in order to accommodate the mechanism.
