The measurements are taken across from point to point: 22", 29", 42", 48" and 64". The depth is 3" to 7" depending on the size of the star. Due to their handcrafted nature, the sizes are approximate and can vary by one inch on the bigger stars. There is a metal tab on the back so they can be hung on a wall. The 64" stars have holes on the tips of the stars so all 5 points can be attached to the wall.
The 42", 48" and 64" stars are shipped unassembled, but are very easy to assemble. Nuts and bolts are included. The 22" and the 29" stars are already assembled so they take a larger box.
