Security Doors questions, answered by experts

The most common size for an interior door is 80 inches tall and 28 to 32 inches wide. However, a standard interior door can measure anywhere from 24 to 36 inches wide, depending on its intended use and the available space. According to most building codes in the U.S., a door must be at least 80 inches tall and 24 inches wide.

No, you cannot install a door without a jamb. The jamb is where the hinges, strike plate, and trim are attached. A person could ostensibly attach the hinges to the door frame itself, but it would hamper the door from opening and closing like normal. Door jambs also provide crucial support for the door and security for exterior entryways.

Bifold doors are a practical and space-saving option for closets, especially if you're figuring out how to design a closet in smaller rooms. This door style allows full access to the closet opening while taking up less floor space than traditional swing doors. Bifold doors come in a variety of styles, materials, and finishes to match any decor.

To achieve the correct opening size for a 30-inch door, add 2 inches to the door width and 2 ½ inches to the door height. For example, if you have a 30-inch-wide door with an 80-inch height, then the rough opening would measure 32 inches wide by 82 1/2 inches high

No, exterior doors don’t need to be prehung, although choosing a door that is prehung makes the installation process far easier. Installing an exterior door that isn’t prehung requires carefully maneuvering the heavy door into place in your door frame, making sure it’s level and plumb on all sides, and then attaching the hinges so that they’re perfectly level and are affixed to the right part of your frame and door. Prehung exterior doors are far more DIY-friendly.
