Lacrosse goals are 6' X 6' and made out of metal with a net that attaches to the metal pipes. Practice lacrosse goals or backyard lacrosse goals are good for practicing lacrosse at home. Lacrosse practice goals are light and portable to take anywhere and are easy to set up. Official lacrosse goals are heavy to withstand all the shots and not move. Usually official lacrosse goals have thicker nets than practice lacrosse goals but thicker nets can also be attached to practice lacrosse goals.
