Cattle Class

“Seat designers often make the assumption that nearly everyone will be accommodated if they design a seat for a man in the 95th percentile of measurements, meaning that they are larger than all but 5 percent of other men — and, theoretically, all women. But even in that group, there are big differences.

Take the buttock-to-knee measurement of the largest men in the study: In the North American group, the average measurement was 26.5 inches, but the Dutch men were larger, measuring 27.6 inches. Factor in the fact that nobody on an airplane sits upright with the knees bent at a 90 degree angle, plus variations in calf length and thigh length.

A big flaw in seat design, however, is that men in the 95th percentile are not necessarily larger than women, particularly in the parts of the body that are resting on the seat.”
