Mine is 13 3/8 hub center to fender front, and 13 3/4 in the rear.....that is roughly 25.5 +/- 1/4 on the front from ground to fender and about 26.0 rear. ( 265/35/18 Neovas on 10.5" rims with about 1/2 tread left)

Those are the average on as flat a ground as I could find....Plus it's corner weighted so they aren't the same on both sides

Edit: I just realized I had some heavy tools in the trunk...so re-measured the rear was almost 1/2 in higher or about 14 1/4 from center to rim

for geometry, don't go below 26" with a 25.3" diameter tire or equivalent based on your tire diameter

however, you may not be able to go this low due to insufficient shock travel clearance depending on what you have

26 -[ (25.3 - X)/2] where X = your tire OD

experience, but it's just a general rule of thumb and you may want to experiment for yourself. 1/4" may be within the range of opinionated error ...
