If home depot is doing the ptoject, they will charge a 50 dollar fee that can be applied to the purchase to measure.
Measure with a steel tape measure. Measure all four sides of the opening. The left will be a little different length than the right and the top different from the bottom. These 4 measurements define the opening. Now add door jams or hinges to let the door swing in AND out.
