Bath towels and washcloths can be made of the exact same material, the only difference being the size. Wash towels or washcloths usually measure about 12" x 12", which makes them the smallest towel option out there. At home, they are most often used to wash and dry the face, but they can also be used for cleaning and exfoliating the body while in the shower. In a salon or spa setting, white washcloths are popular for facials and waxing procedures. The next in size are hand towels, followed by bath towels and bath sheets. Bath towels cover a larger area, which makes them ideal for drying the body and hair without being overly heavy. Bath sheets are 70" long and are most often used for wrapping up after showers, massages, or spa treatments.
