In a car, the wheelbase is measured between the center of the front and rear axles. Quite simply, it's the distance between the center of the front axles and the center of the rear axles. Measuring the wheelbase of your car could easily be done with just a tape measure, chalk, and a square measure. Crucially, you also need a flat surface to park your car on, just so we could measure it more precisely. First thing's first, place your square measure against the wheel, standing upright. Ensure that the vertical section is as closely aligned to the center cap as possible. Then, mark on the ground this center line with chalk. Repeat this process for the rear wheels. Now, use that tape measure to find out the distance between these two chalk marks to find the wheelbase.
