Which string angle to use?

Using the charts below. The first step is to determine the bow’s brace height. This is the distance from the string to the thumb web section of the bow’s grip. Round this number up or down to the closest inch. (For example, a 6¼” brace height bow would use the 6” brace height chart. A 6¾” brace height bow would use the 7” brace height chart.)
Next, find the bow’s axle-to-axle length on the left axis of the chart. The final step is to move horizontally within that row until you come to the column with the bow’s draw length. This will indicate the preferred peep string angle for your bow.

NOTE: if your setup falls on the dividing line between the 37 and 45 degree sections of the charts, you can use either string angle. For example, a 7” brace height bow, 36” axle-to-axle, and a 27½” draw length falls right on the boundary, and could use either a 37 or 45 degree string angle peep housing.
