The Wrist ID Sport is available in three different sizes. See below to determine which size is right for you.
STEP 1: Fold a dollar bill in half. (No dollar bill? Simply use a 6.125" or 15.5cm strip of paper.)
STEP 2: Gently wrap around your wrist. Note the width of the "gap" between the edges. (For proper sizing, do not wrap the dollar too tightly.)
Gap is LESS than 1/4" (0.6cm) or the bill overlaps
MEDIUM/LARGE: most common size
Gap is between 1/4"(.6cm) and 2" (5cm)
Gap is GREATER than 2" (5cm)
