Will a Yukon XL fit in a 20-foot garage?
A nominal 20-foot garage is 240 inches deep. Subtracting a 225.2-inch Yukon XL leaves 14.8 inches of total clearance:
240 in. garage depth − 225.2 in. vehicle length = 14.8 in. remaining
That 14.8 inches must cover clearance at both the front and rear; it is not 14.8 inches at each end. If the SUV were centered, the theoretical clearance would be 7.4 inches per end. A 225.6-inch AT4 would leave 14.4 inches total.
Measure the actual usable depth at bumper height, from the closed garage door or its nearest hardware to the back wall or nearest obstruction. Shelving, wall trim, door handles and the space needed to walk around the SUV can make a garage’s advertised depth misleading.
