You have to use known dimensions to do a side-by-side comparison (and it doesn't always work).
The distance from the trailing edge of the front wing end plate and the face of the front wheel is standard for all cars. The distance between the front of the cockpit opening - indicated by the windscreen - and the headrest is standard for all cars. Naturally, the diameter of the wheels is also standard.
There are other common areas, as well, and the more you can match up, the better.
My comparison uses three that cover the front, mid-section, and rear of the car. Because each of those areas are the same size in both pictures, and because we know those dimensions cannot legally vary in reality, we can make a reasonably valid comparison between the two cars based upon the photos, confident that proportion and perspective are at least nominally representative.

The comparison is further bolstered by the shared location of the tea trays, which cannot lie ahead of the rear face of the front wheels, and by the shared location of the airbox inlets/roll hoops, which cannot advance more than XXmm behind the headrest.
There's little, if any, difference between the wheelbase of SF15-T and that of SF16-H.
