What is toilet paper girth test?

The toilet paper girth test is a method used to determine the thickness and absorbency of toilet paper. It involves wrapping a single sheet of toilet paper around a cardboard tube and measuring the resulting thickness or girth. This test is commonly used by manufacturers and consumers to compare the quality of different brands of toilet paper. A higher girth measurement indicates that the toilet paper is thicker and more absorbent, making it more effective for cleaning and reducing the need for excess usage.
