It comes on a spool of 1094 Yards / 1000 meters. This is much more length than you will find sold in traditional fabric shops (usually around 100 meters to 500 meters). The spools are not overly large, 3" tall and 1.25" in diameter so they can be used on standard home sewing machines but its a tight fit - please measure your thread holder
