DH made me one that sits on top of one end of my cutting table, it is 24 by 48. It is wide enough to iron 45 inch wide fabric. I also have one of the small table top ironing boards on a wheeled cart that I can pull up close to the sewing machine and reach it while sitting. I have 2 30 by 60 inch tables together, on risers DH made. My large ironing board at one end makes it convenient to iron long pieces of fabric and collects on the table and off the floor. That still leaves me plenty of room to have a large cutting mat and work space.
