Before the invention of the compound bow, the recurve bow was the last word in both power and accuracy in the realm of archery. Today, despite the popularity of the compound bow, the recurve bow still sees action in the hand of amateur hobbyists and archery enthusiasts. Of course, as anyone who has ever owned a bow for any length of time will tell you, the bowstring on your bow will eventually need to be replaced. When this happens, it is imperative that you get a bowstring of the correct length to replace the one you have, or else you risk damaging your bow and yourself.
Unstring the bow--if necessary--and lay it flat on the ground.
Use your measuring tape to measure the distance between the two tips of the recurve bow. The appropriate length for your new bowstring will be four inches less than the distance between the bow tips. Confirm this using the next two steps.
Wait one day for the old bowstring to return to its original size.
Loop the end of the bowstring around a nail or similarly fixed object, then draw the string out so that it is hand-tight.
Measure the length of the old bowstring with the measuring tape.
