WPA/BCA-legal jump cues (including jump cue sections of jump–break cues) available from major manufacturers vary in length typically from a specified minimum of 40 inch, up to 44 inch, with short butts of 10 to 14 inch. However, some players jump with a full-length normal cue. Jump cue Shafts are usually normal length – around 29 to 30 inch – diameter, and taper, but may be shorter (with a longer butt) and/or thinner. They have tip diameters that range from around 12.75 mm to a specified maximum of 14 mm. Jump cue weights usually range from 5 to 10 oz The thinner, shorter and lighter-weight models are designed for higher, shorter-distance jump shots executed closer to an object ball, while the larger ones are primarily for executing longer-range shots. Jump ferrules are often made of phenolic resin or Bakelite (and may be in the form of a one-piece tip and ferrule in either case), extra-hard fiberglass or brass, although some models use the same normal fiberglass or hard plastic as the manufacturer's other cues.
