1. TIP: Fold a dollar bill in half and use the longer horizontal edge to measure the width of your fingers at the point where your fingers meet your palm or place your hand on top of a ruler to measure the width of your hand from point A to point B as shown above. Keep your fingers tightly closed while measuring. If you don’t have a ruler, print out this document at Actual Size (100% scale). Do NOT choose “Fit” or “Scale to Fit”. Use the printed ruler at the bottom of the page to measure the width of your hand from point A to point B as shown in the hand alignment diagram. Keep your fingers tightly closed while measuring.
  2. If your hand width is larger than the folded dollar bill, or about 76 mm (3 in) or larger, then order size L. If your hand width is clearly smaller than the folded dollar bill, or less than 76 mm (3 in) then order size S.  If your hand is in between sizes and you cant decide go for size L.

NOTE: We don’t recommend ordering Tap for young children or people with very small hands (span less than 57 mm (2 ¼ in)
