  • Draw Length Calculator

    Your draw length is the distance from the bowstring at full draw to a reference point on the bow. Get it right and your posture, anchor point, sight picture, and release all feel natural—leading to tighter groups and less fatigue. Get it wrong and you’ll fight the bow: floating pins, facial pressure, string slap, and…

  • Arc Length Calculator

    Arc Length Calculator About Arc Length: Arc length is the distance along the curved line making up the arc. It can be calculated using the radius and central angle (θ) with the formula: Arc Length = r × θ (when θ is in radians) or Arc Length = (θ/360°) × 2πr (when θ is in…
