For trees greater than four inches in diameter up to and including 12 inches, the caliper measurement must be taken at 12 inches above the ground level. For trees greater than 12 inches in diameter, the trunk is measured at breast height (diameter at breast height or DBH), which is 4.5 feet above the ground.
