Slight variations in base paths and pitching rubber distances make it difficult to calculate the exact area of the skinned infield, but the numbers expressed in the chart below can be used as a guide. Shown, too, is approximately how much infield mix is needed to get one inch of coverage on different fields. This number can vary depending on the type of infield mix used. It’s best to order full truckloads of bulk material. A legal full truck is 20 tons (roughly 16 yards).
