Entry or exterior doors must have a height of 80 inches minimum. They can go up to 96 inches in standard sizing, and, again, custom doors could be even taller.
Depending on the product selected required headroom for a standard installation is typically between 12 and 18 inches. So, if you are using a door that is seven feet high the typical minimum ceiling height would be eight feet, leaving twelve inches of headroom.
The minimum clear opening height of doorways shall be 80 inches (2032 mm ... ). The minimum net clear opening height dimension shall be 24 inches (610 mm).
Trackless systems, for example, eliminate the need for traditional overhead tracks, allowing for a sleek and compact design that maximizes the available headroom. Low-headroom garage door systems are comprised of specialized hardware and components that work together to reduce the amount of space needed above the door.
A standard roller door is produced to measure and fit openings up to 3m high x 5.5m wide and require 450mm of headroom. A standard sectional door is produced to measure and fit openings up to 3m high x 6m wide and require 250mm – 350mm of headroom.
Low-headroom doors require less headroom than other doors, allowing you to maximize performance when there's not enough vertical space to install a regular high-performance door. For example, Rytec's Spiral® LH® door is engineered for low-headroom applications requiring only 11 inches of clearance.
The minimum clear opening height for a doorway is 80 inches, with an exception that allows door closers and overhead stops to be 78 inches (minimum) above the finished floor or ground.
❖ A minimum headroom clearance of 6 feet, 8 inches (2032 mm) is required in connection with every stairway. This includes not only the above-the-tread portion, but also above any landings serving the stairway.
For reference, standard interior door widths range from 24"-36" (finished opening). While a standard door height is 80" (finished opening). The difference between a rough opening and finished opening is usually 2-3 inches.
The recommended headroom usually depends on the type of garage and the type and size of the door you are installing. Thus, a typical garage ceiling height of a standard residential garage is about 8', and the recommended required space is 12' for a manually operated and 15' for an automatic garage door.

With a subject placed one-third of the way down from the top of the frame, the subject aligns with the proper headroom to make an image pleasing to the eye. This technique has carried on with other visual forms of art such as photography and cinematography.
Building regs: minimum internal door height
Within the building regulations, no minimum internal door height is stipulated.
Q: What are the smallest exterior door sizes available? A: The smallest standard exterior door size is 30 inches wide by 80 inches tall, but custom sizes can be made to fit specific needs.
Per the IRC (and most all the derivative codes), the clear headroom must be 6'-8" "....in all parts of the stairway".
Adequate headroom is necessary to ensure safety and comfort when moving through spaces like stairways, hallways, and doorways. Building codes specify minimum headroom requirements to prevent injuries and ensure that spaces are functional for their intended use.
While the mastering engineer (whether that's you or someone else) might aim to squeeze the headroom of the final master down as far as 0.1dB, since there's no further processing to allow for, the mix engineer should always aim to leave between 3 and 6dB of headroom – ie, have the loudest point in the track pegging the ...
Standard Height of Interior Door
The Code generally requires the standard height of the interior door to be a minimum of 80 inches but there are certain codes that allow doors to be 78 inches. Interior doors that measure 80 inches are 6 foot and 8 inches and this is the reason they are called 6/8 doors.
