Hi @Km, the women's down Marmot sleeping bags are 66" for the regular and 70" for the long. They are true to their specs in that the regular will accommodate up to 5'6" and the tall will accommodate up to 5'10". If you are on the fence about which size to choose, consider if you plan to put a hot water bottle in the bottom of the bag or if there would be any other reason to have just a little extra room. Too much space will mean more area for your body to heat so you're really looking for that sweet spot in-between. I hope this information is helpful. Happy adventuring!
