How to measure your vehicle
Measure the opening at its narrowest point: between the latch, weatherstrip and trim, not the painted body. Measure its height the same way, at the lowest point of the roof or lip.
Then measure the usable floor from the trunk lip or tailgate edge to the back of the front seats, with the rear seats in the position you will actually use. Measure the height inside where the roof slopes down, not only at the opening.
A long carton loads one end first, so the opening and the floor length both have to work. Enter your own numbers in the checker above for a result about your vehicle rather than a generic one.
