Hello ShortBob, and welcome to the community!


The easiest way to measure for a new patio door is to measure your old patio door! First, carefully remove the trim around the inside of the door frame, this trim is called casing. Once the trim is removed you will see the perimeter frame of the door and the studs next to it.   The casing can be reused if it doesn't break upon removal. 


Measure from the inside of each 2x4 (stud), this is your R/O (rough opening), make sure you take 2 horizontal measurements, across the top, near the bottom and twice vertically, and use the smallest of each, horizontally and vertically. You can bring a diagram with your measurements to Home Depot and someone will assist you with your project. 


Please let me know if you have any other questions.
