Under the rules on club length, it says that the maximum length of a club is 48" but that putters are excluded. But it goes right on to describe the differences in the method of measuring the length of a wood/iron and a putter.

If there's no limit on putter length, why do they bother explaining in detail how to measure it's length?

Wouldn't you think they should set max length of a putter so that those with long putters do not have an advantge when dropping a ball.

PS: I have a 50" putter!
