A jeans size chart is a number table that lists all the sizes for jeans and their equivalent measurements. This enables shoppers to find the correct size and fit.
While all jeans manufacturers have different sizing guidelines and numbers, they all base their sizes on women's body measurements. According to About Style, the best way to get the correct fit on a new pair of jeans is to measure the waist and hips and then match those measurements to the corresponding size on the chart. It's also important to not hold the measuring tape too tight to the body to ensure a comfortable fit.
