I make my bows with equal length limbs, I find the center of the bow, measure up 1 1/2 for arrow rest and down 2 1/2 for bottom of grip. That gives you a 4 inch grip, I also measure up 2 1/2, so that gives you a 5 inch handle so to speak. Then from the 2 1/2 marks I measure out another 2 inches for the flares on top and same on the bottom, then I measure out 2 inches from the flares and that is where the riser fades into the limbs. In the second picture down you can see in yellow BH and TH, that is 5 inches, and just to the left of the TH and inch down is another line, that is where my arrow shelf will be.
