Shapes and Sizes
Trauma plates can be found in a variety of sizes and shapes. The most common shapes are rectangle, rounded rectangle and irregular hexagon.
In concealed vests (vests worn under a shirt), the trauma plates are most commonly 5″ × 8″, with variants including 5″ × 7″, 5″ × 9″, 6″ × 8″, and 6″ × 9″. Thickness (depth) varies based on material and application but rarely exceed 1/4″.
In tactical vests, worn as outerwear, the trauma plates are most commonly 10″ × 12″ with some variation depending on the vest. Thickness varies, depending on material and application, but rarely approaches 1/2″.
In specialized/military-grade vests, a considerable portion of the vest is made up of rigid, trauma-plate like inserts. Since they are an essential part of the vest, they are NOT typically considered the same as trauma plates and are typically referred to as inserts, much like the aramid ballistic inserts found in concealed, duty, and tactical vests. SAPI vests are an example of this type of vest. In most SAPI based vests/carriers, the outer vest is made out of and lined with aramid material is made to carry multiple ballistic inserts, typically made out of ceramics. These inserts are shaped to fit the carrier and have sizes that vary depending on the size and shape of the vest.

Famous quotes containing the word shapes:
“One perceives that again and again she has destroyed her life when it was forming into shapes of happiness because of her loyalty to the early misery, her conviction that that has the sanction of ultimate reality, and that beside it all other things are trivial.”
—Rebecca West (1892–1983)
