There are tiny pores and holes at the surface of a sheet of paper towel that resembles a sponge. This special structure helps them be more absorbent.

Walker, a writer for the Virginian-Pilot, compared toilet paper brands and found a dizzying variety of sizes, including double, double-plus, giant, big, “Big Squeeze,” “Mega” and “Mega Plus.” Changes in the size and number of sheets make it difficult for consumers to compare one product to another.
A standard roll of toilet paper was obtained. It was found to have an outer radius (Ro) of 55mm and an inner radius (R) of 20mm.
