Independent of fat percentage, weight or width, female body shapes are categorised into one of four elementary geometric shapes,[1] though there are very wide ranges of actual sizes within each shape:
Apple (triangle downward)
Apple shaped women have broad(er) shoulders compared to their (narrower) hips.[1] Women of this body type have (much) higher androgen levels compared to women with other body types[citation needed]. Because of this high androgen level, the skeleton develops in a very masculine pattern. Apple shaped women tend to have slim legs/thighs, while the abdomen and chest look out of proportion compared to the rest of the body. Fat is mainly distributed in the abdomen, chest, and face.
Banana or straight (rectangular)
The waist measurement is less than 9 inches smaller than the hips or bust measurement.[1] The body has a relatively high androgen level compared to the estrogen level[citation needed]; this causes the skeleton to develop in a bit more masculine pattern and body fat to be distributed predominantly in the abdomen, buttocks, chest, and face. This overall fat distribution creates the typical ruler (straight) shape.
Pear or spoon or bell (triangle upward)
The hip measurement is greater than the bust measurement.[1] The distribution of fat varies, with fat tending to deposit first in the buttocks, hips, and thighs. As body fat percentage increases, an increasing proportion of body fat is distributed around the waist and upper abdomen. The women of this body type tend to have a (relatively) larger rear, robust thighs, and a small(er) bosom.

Hourglass shape. (triangles opposing, facing in)
The hip and bust are almost of equal size with a narrow waist.[1] Body fat distribution tends to be around both the upper body and lower body. This body type enlarges the arms, chest, hips, and rear before other parts, such as the waist and upper abdomen. An hourgass shape is considered to be a well-known epitome of feminine beauty.
A study of over 6,000 women carried out by researchers at the North Carolina State University around 2005 found that 46% were banana (rectangular), just over 20% pear, just under 14% apple, and 8% hourglass.[1] Another study has found "that the average woman's waistline had expanded by six inches since the 1950s" and that today women are taller and have bigger busts and hips than those of the 1950s.[1]
