I recently made a set 9" that I really enjoy. I upped the length from 8" . The longer hammers add a bit more bounce. Different woods, lengths, weights. There's no end to finding the prefect hammer. But its fun... Robert

I just measured my favorites, and the wood portion is 23-1/4 cm long. My backup hammers are 22-1/2 cm. We don't have any that are shorter.

A good "ballpark" length is something between 20 - 22 centimeters.  You alter the mass of the hammer by altering the thickness and width of the handles, heads and grips.

Could somebody tell me what the total length of a standard hammer is please including handle and head? I know they vary but an about figure would be great, thanks Nige
