A Guide to the Rules on Clubs and Balls

Length

Appendix II, 1c states that:

 The overall length of the club must be at least 18 inches (0.457m) and,except for putters, must not exceed 48 inches (1.219m).

This Rule is straightforward and the measurement of woods and irons is well described and illustrated in both the Rule book and the official test protocol. The measurement of length for putters can be illustrated in Figure 3.

Putter Length

The above Rules on club length mean that long "‘broomhandled" putters are still conforming. However, The R&A has adopted a position that clubs designed for chipping, including modified wedges, that are longer than standard length clubs of similar loft are not traditional and customary in form and make (see Appendix II, 1a). The following table is used for the purpose of determining the maximum allowable length of a chipping club.

Loft Range (°)   

 Minimum Loft 16  20  23  26  29  33  37  41  45 
 Maximum Loft 19  22  25  28  32  36  40  44  48 
 Maximum Allowable Length (in) 41.5  41  40.5  40  39.5  39  38.5  38  37.5 
 Maximum Allowable Length (m) 1.054  1.041  1.029  1.016  1.003  0.991  0.978  0.965  0.953
