Other forms: thicknesses
The word thickness refers to the distance between the sides of an object, or how dense and solid something feels — like the weight of a cozy blanket or the richness of a creamy soup.
Thickness can refer to the physical width of an item, like the thickness of a book or a slice of bread. It can also describe the concentration of a substance, such as the thickness of paint on a wall. Thickness can even describe something’s heaviness or sturdiness, like the solid weight of a durable winter coat.
