Codes will vary place to place, 18" is common for non-tempered glass. If you want to pay about 30% extra you can get tempered glass and go all the way to the floor like in a door or sliding window which have tempered glass.

THE ONLY PLACE THAT CAN ANSWER THIS QUESTION IS YOUR LOCAL PERMIT OFFICE! Codes change depending on where you live. Standard ceiling height in Canada and the US is about 8 feet.I'm going to assume your thinking about adding a bedroom in your basement.For APARTMENTS there is a minimum of 6.8 feet from finished floor to finished ceiling for all living space. There may be exceptions for under beams and bulkheads. You may need to add more head room for lighting.I haven't seen anything about minimum ceiling height for a regular house specifically. There are codes for window size, egress, heating, the kind of electrical outlets, square footage of the room, you need a dedicated closet, and there must be a smoke/CO detector within a few feet of the door.
The top of a window in a usual application in a wall that is 8' high is around 7'.

The minimum distance from ground level to the bottom of windows in basements can vary based on local building codes and regulations. These regulations are typically in place to ensure proper safety, natural light, and ventilation for habitable spaces. It's important to consult with local authorities or building professionals in your specific jurisdiction to determine the exact requirements. However, as a general guideline: Egress Windows: In many jurisdictions, basements used as habitable spaces, such as bedrooms, are required to have egress windows. An egress window is a window that is large enough to provide a safe emergency exit in case of fire or other emergencies. The specific requirements for egress windows can vary, but they typically have minimum width, height, and clear opening size requirements. The bottom of the egress window is typically required to be a certain distance above the finished floor level of the basement, rather than ground level directly outside the window. Natural Light and Ventilation: Even for non-egress windows in basements, there are often regulations in place to ensure sufficient natural light and ventilation. These requirements may specify a minimum height or distance between the bottom of the window and the finished floor level to allow for proper light transmission and airflow. To ensure compliance with local regulations and building codes, it is strongly recommended to contact your local building department or consult with a qualified architect, contractor, or building professional. They will have the most up-to-date information on the specific requirements for window placement in basements in your area.
An egress window is a basement or below grounf level. It has to be big enough for people to exit through in case of an emergency. The minimum size for an egress window is 18" wide and 30" high. The maximum size is 54" wide and 72" high.
You do need to have ventilation in a bedroom. But more important you need egress. At least one window in each bedroom must be of sufficient size to permit the occupants to escape a fire and also to allow a fully outfitted firefighter to enter. An egress window must satisfy all four International Residential Code (IRC) criteria: Minimum width of opening: 20 in. Minimum height of opening: 24 in. Minimum net clear opening: 5.7 sq. ft. (5.0 sq. ft. for ground floor). Maximum sill height above floor: 44 in. ;) MINI
Emergency egress requirments. 5.0 sqr ft at grade level and 5.7 sqr ft below or above grade (second floor and above). 24" clear opening height minimum. 20" clear opening width minimum.
An awning type window does not offer easy egress, but any type of window that isn't large enough, or doesn't open wide enough, can cause egress problems.

5 feet Egress for a bedroom requires a 3' x 5' window , minimum. Therfore it is a common size, refered to as a 3 O 5 O .
Since a basement has only one entrance and exit, by OSHA definition, your basement is a confined space. Entering it technically requires an entry permit and is a hazardous environment. (think about it. If a fire breaks out at the top of the stairs, how would you get out?) An egress window solves this problem by being able to be opened in an emergency to allow exit to ground level. A shaft with a retaining wall and built in ladder rungs are required on the outside of the window. For added security, a grate that opens from inside can be fitted over the top of the shaft and secured from the inside.
bottom - 49" top - 43" height - 14"
In Ontario, Canada, a basement window to be used for egress must have a minimum open area of 3.8 ft² and no dimension less than 15" when open. This requirement changes to 4.1 ft² and no dimension less than 18" when the basement is a separate dwelling unit (i.e. basement apartment).

Yes. As long as it meets the required distance from the floor and the minimum square footage opening. Example - where I am the opening must be 5.7 square feet or larger.
