The stubby!! | Golf Monthly

The rules are pretty clear on what makes a compliant putter.

View attachment 13968

From the pictures of the putter it would appear that heal to toe of face = heal to toe of club head so for this A=B

If A = 46mm and C= 42mm then the condition that A>C is met.

A ≤ 7" = YES.

2/3 of C = 28mm therefore B is ≥ 2/3C

B=A so is ≥1/2 A

The only measurement left to check in D which I would doubt is greater than 2.5"

So it would appear that this is a compliant head.
