How do you determine spoke length?
Pull both spoke heads inward towards the center to seat the nipples. Using the narrow tips of the caliper jaws, measure from inside to inside of each J-bend. Record this measurement to the nearest tenth of a millimeter. In our example, each spoke measured 266 mm, with the J-bend-to-J-bend at 35.7 mm.
How accurate do spoke lengths need to be?
You should only round 0.1 or 0.2mm up, the rest goes rounding down. On a double wall rim, you can round to the nearest size. There is about as much freedom in rounding down than there is in rounding up.

The outer diameter is the hub bore, while the inner diameter is the diameter of the vehicle hub itself. For example: a hub-centric ring size of 73-67.1 would mean that the wheel center bore is 73 mm wide and the vehicle hub is 67.1 mm wide.
How is ERD calculated?
Measure the length of a nipple (dimension B in the figure) and add it twice (once for each nipple). The result is Effective Rim Diameter (ERD). Thus, ERD = A + 2B.
