This measurement combined with knowing the total weight of you putter will enable me to calculate its swingweight. Get a rough idea of the balance point of your putter by balancing the shaft on your finger. Keep that point as a reference and cover it with a 2 inch strip of masking tape. Then measure the exact balance point from the butt end of the grip to a marked point on the masking tape when you use a system like shown in the picture.
