what is the width of an average bedroom door
2' 6 is a standard door for all bath and bedrooms. I would have to see your layout, you could use a 2' 8 door but in a standard bathroom it be a problem where the casing meets the vanity. 21 or 18 deep vanity? good luck.
The standard height for French doors is around 6 ft. and 8 inches & 8 ft. The standard width is 80 inches. There are also Retro French Doors sizes. They are 2 inches smaller than the width and height of regular French doors.
