A box-style soccer goal is a goal that has equal back-depth on the top and the bottom of the goal. For example a soccer goal with a height of 8', a width of 24' a top back-depth of 6' and bottom back-depth of 6' would be a box-style soccer. Whereas another popular size goal with a height of 8', a width of 24' a top back-depth of 3' and bottom back-depth of 8' would not be.
