A human skull and measurement device from 1902. Craniometry is measurement of the cranium (the main part of the skull), usually the human cranium.It is a subset of cephalometry, measurement of the head, which in humans is a subset of anthropometry, measurement of the human body.
A standard measure for assessing an animal's brain size compared to what would be expected from its body size is known as the encephalization quotient. The encephalization quotient for humans is between 7.4-7.8. [61] When the mammalian brain increases in size, not all parts increase at the same rate. [62]
The phrenologist would often take measurements with a tape measure of the overall head size and more rarely employ a craniometer, a special version of a caliper. In general, instruments to measure sizes of cranium continued to be used after the mainstream phrenology had ended.
Cephalic index viewed from above the head. The cephalic index or cranial index is a number obtained by taking the maximum width (biparietal diameter or BPD, side to side) of the head of an organism, multiplying it by 100 and then dividing it by their maximum length (occipitofrontal diameter or OFD, front to back). The index was once used to ...
The human head consists of a fleshy outer portion, which surrounds the bony skull. The brain is enclosed within the skull. There are 22 bones in the human head. The head rests on the neck, and the seven cervical vertebrae support it. The human head typically weighs between 2.3 and 5 kilograms (5.1 and 11.0 lb) Over 98% of humans fit into this ...

There are a number of important distances between reference points that an artist may measure and will observe: [1] These are the distance from floor to the patella; [a] from the patella to the front iliac crest; [b] the distance across the stomach between the iliac crests; the distances (which may differ according to pose) from the iliac crests to the suprasternal notch between the clavicles ...
