The threads of all four spokes in the image below extend equally far. The leftmost nipple is threaded on until the threads start to bind. The next spoke nipple is threaded on until the end of the spoke is level with the top of the nipple's screwdriver slot, as far as it can go without risk to the inner tube. The rightmost nipple is threaded on only far enough to conceal the threads of the spoke, risking nipple breakage. Comparing the leftmost spoke with the bare one shows that the internal threads of the nipple extend down about as far as the base of the wrench flats.

I thank Roger Musson for permission to use the photo below, with cross-sectioned spoke nipples. The spoke threads are the same length in all three examples, but the spoke nipples are of different lengths. A spoke can be threaded in only until the red line in the picture reaches the bottom of the threading in the spoke nipple. Beyond that limit, it will bind. The combination on the left risks breaking the spoke nipple just below the head, because the spoke does not extend up into the head of the nipple. Only the short spoke nipple at the right is really suitable for the spokes shown.
