A lot of people think they need to buy a string based on the length of their previous string or their bow length while it is strung. This is not the case. Bow sizes and string lengths are based on a standard known as AMO. AMO is a standardized set of measurements for archery bows, strings and equipment. For example, if your bow has an AMO length of 60 inches, when strung it will typically be 57 inches due to the curve in the bow limbs and the string it uses will also be 57 inches in length.The string you need for your bow will typically be 3 to 4 inches shorter than your bow's unstrung length, depending on the bow's type.When purchasing a bowstring, string manufacturers have already taken it into account. When purchasing a bowstring, you want to match the two AMO sizes. If it is labelled as 60 inch AMO bowstring it means it fits a 60 inch AMO bow, which means the string itself will be around 57 inches.For example, if you purchase a 60" AMO Samick Sage, you can buy a 60 inch AMO string, and it will fit your bow. The string itself will be 57 inches which is what fits a 60 inch AMO bowBowstring will always be listed by AMO length, not actual string length, which leads to confusion among new archers. If you were to measure your recurve string at 57 inch and buy an AMO 57 string, the AMO 57 string would be three inches shorter at 54 inches in total length.Almost all traditional recurve bows sold by Canada Archery will have the AMO length listed on the box or limbs. For Olympic Recurve equipment, you will typically already know the AMO length of your bow, which is usually between 64 and 70 inches long. This depends on how long your riser is bolt to bolt, in combination with if you have chosen to use short, medium or long limbs. It can be tricky for custom-made bows unless the bow maker gives you the AMO length. Normally, you would measure the old string that came with the bow and add 3 to 3.5 inches to get its AMO size.
