We use real Hawaiian print fabric, laminated to a high quality birch plywood. These surfboard shaped growth charts are a fun and stylish way to keep track of growing kids. Transfer those old marks on the wall or door jamb to this board and have a permanent record to hand down to future generations! The measurements on the chart start at 24″ and are marked every 3″ up to 63″. Specs: 45″ Long X 10″ Wide X 1/2″ Thick. Mounting hardware and instructions included. Hand made by us in the USA.
