The 5 male body shapes are trapezoid, inverted triangle, rectangle, triangle and oval. The male body shapes follow the common fashion classification, and the measurement rules on this page are this site's own, because no research standard for male shape classes exists.

A male body shape is the proportion between a man's chest, waist and hips. The male body shape calculator checks the five male body shapes below in order: oval, triangle, inverted triangle, trapezoid, rectangle.
1. Oval
Oval male body shape is a figure where the waist is equal to or larger than the chest. Oval figures carry width at the midsection. Clothes for an oval shape add structure at the shoulders and keep a straight line through the torso.
2. Triangle
Triangle male body shape is a figure where the hips are at least 2 inches (5.1 cm) wider than the chest. Triangle figures are narrower at the shoulders. Clothes for a triangle shape add width at the shoulders with structured jackets.
3. Inverted Triangle
Inverted triangle male body shape is a figure where the chest is at least 10 inches (25.4 cm) larger than the waist. Inverted triangle figures form a strong V shape. Clothes for an inverted triangle shape balance broad shoulders with straight trousers.
4. Trapezoid
Trapezoid male body shape is a figure where the chest is 5 to under 10 inches (12.7–25.4 cm) larger than the waist. Trapezoid figures taper gradually from chest to waist. Most off-the-rack clothing fits a trapezoid shape without changes.
5. Rectangle
Rectangle male body shape is a figure where the chest is less than 5 inches (12.7 cm) larger than the waist. Rectangle figures have straight sides. Clothes for a rectangle shape add shape with layers and fitted jackets.

Are Male Body Shapes the Same as Somatotypes?
