Our size medium bibs are 13" wide and 13" long from chin to bottom and fit kids starting about the size of 8 year olds up to small teenagers. It depends on the amount of coverage you would like. Choose from hundreds of available fabrics. We have prints, solids, and terry cloth. Our bibs come in a Standard Absorbency, which has a flannel inner layer that works well as a basic bib for mealtime and light fluids; and a Soaker Absorbency, which has a terry cloth inner layer and works better for bigger messes and heavy fluid spills and drool. All of our bibs have a soft, flexible cloth waterproof backing layer that will not crack. Choose your thickness, and click below.
