Darts is also a great game for kids and adults. A lot is written online for adults and their rules, but you may be wondering "What is the official height of a dartboard for children"? In this article, we give you the answer. Height dartboard for children During competitions - including youth competitions - the dartboard must always be hung at a height of 5.67 feet. There are no different rules for children. For children, the dart distance is the same: the throw line is 7.77 feet away. These are the official rules for darts, but if your child is not yet an adult we recommend lowering the dart. Darts are about position and technique, not strength. If hung at the official height of the dartboard, it probably looks more like a javelin. In addition, your child teaches himself the wrong technique.
