The rails/rods are 91 inches long and 1.25" square. They are covered in scrap cloth for pinning on the quilt top. The side supports adjust from about 26 to 31" wide and the height is adjustable from about 22 to 35". It is big enough to make a queen sized quilt. It folds up very compact and is very easy to adjust. The last photo is a stock photo from another website that shows the side supports in better light conditions. Can call or text phone number below. Cash sale on pickup only Thank You.
