Depending on the make of the bow, you can get the draw weight in your draw length. Another thing to consider, the length of the bow will determine the stack the bow has. I've shot some shorter bows at #45 that feel like #60+
It's like compounds. Shoot as many as you can before you buy. Some of the high end bows (BlackWidow, Stalker Stick bows) have a program that lets you test one before you buy them.
