Hi Fran,
Great question! This rack is bit wider than some others you may have seen.
21.75” x 17” x 11.25” It is designed to give the proper spacing between spools for the mini-king spool size. Each of the pins is 2" tall, also to properly support this spool size.
Because the rack folds, you can mount it on the wall, but it does not come with the necessary hardware for doing that.
