Standard Door Size
When you are replacing or adding in a new door, you can choose between a pre-hung door and a door slab. A pre-hung door includes the door itself, the door hinges and door frame, which is a great option for a full door and frame replacement. A door slab doesn’t include the frame, hinges, or hardware—it’s the best route if you only want to replace the door panel while preserving the other components. Keep in mind that a standard door size measurement only includes the door panel—not the door frame, door jamb, or door opening.There are many different door sizes available. The right size can depend on the use of the door, the location of the door, building codes, and building type.
Standard Exterior Door Size
Exterior door sizes are dependent upon the International Residential Code (IRC). By IRC building codes, exterior doors are required to be a minimum height of 80 inches. The standard exterior door size is typically 3 feet wide and 80 inches high. Examples of an exterior door include an entry door, back door, garage entry door, or fire/security door. In newer homes, exterior doors can be even taller, with a door height of 96 inches. Stock exterior doors can be readily found in widths of 30 inches and 32 inches, and the standard exterior door thickness is 1 ¾ inches.What is the Standard Garage Door Size?
The standard door size of a garage door can have slight variations, but, on average, a single garage door is about nine feet wide by seven feet high. However, newer homes favor larger standard door sizes for garage doors, with nine to 10-feet widths becoming more common.Standard Interior Door Sizes
Internal door sizes are also determined by the IRC building codes. Interior doors are not required to be as large as the main entry door, but they must be at least 80 inches in height, just like an exterior door.Standard Commercial Door Sizes
For commercial buildings, door sizes are determined by the International Building Code (IBC) requirements and the Americans with Disabilities Act (ADA) standards. These building codes define the maximum and minimum height and width of doors to ensure people can properly enter and exit in the event of an emergency.average door width is 36 inches, and the average door height is 80 inches.
How to Measure a Door
Before you can replace a door in your home or building, you must measure the current door’s width, height, and thickness to get the proper dimensions for your replacement door. If you are replacing your current door with a door slab, rather than a pre-hung door, these measurements are all you will need to choose the correct size.What is the Standard Door Jamb Width?
The door jamb sections make up a whole door frame of an exterior or interior door. The door jambs are important to measure when measuring for a door replacement or custom door. That's because a jamb that's too large for your door may need to be trimmed, while one that's too small could cause problems with the door's appearance or functionality.When taking measurements for a door, you should measure the door jamb width, height, and thickness in addition to measuring the frame.
The space between the door jambs is about 84 inches wide on most doors.
A standard door jamb thickness varies depending on the size of the frame and drywall thickness. For door frames made with 2x4s, 4 9/16 inches to 5 ½ inches is a common thickness range, with the larger size usually found on doors with thicker drywall. A 2x6 frame usually yields a door jamb thickness of 6 9/16 inches.
To measure a door jamb width, include the drywall but not any decorative casing. Use a measuring tape to measure the width from one end of the door jamb to the opposite side jamb's exterior edge.
Standard Door Frame Size
When installing and framing a new door, you must first determine the dimensions of the rough opening. This allows you to properly install a prehung door, which includes the frame, or you can cut your own rough opening to create your own frame. If you have the space, you may want to cut a new rough opening to install a bigger door, especially if you are upgrading from a single door to a double door or installing a door where there wasn’t one before.Standard Door Sizes
When installing a new door, there are a few important steps to take to ensure you have the correct measurements. First, you should decide what type of door you need.
