You need to perform a simple test to determine if your recurve bow string is too tight or loose. First, place the bow on a level surface and ensure the limbs are not twisted. Next, lightly pinch the string at the midpoint between the limbs using your thumb and index finger. It is too loose if there is more than 1/8 inch of space between the bowstring and the deepest part of the grip. It is tight enough if you can only fit a piece of paper between the string and grip. When plucked like a guitar string, a properly tensioned bowstring will produce an audible note. It’s important to maintain proper tension to avoid damage to both your bow and arrows and prevent injury while shooting.
