Adult Cricket Bats
The general rule is if you are more than 5 ft 9 inches and above, you will be suited to a short-handle bat. However, this does not mean you have to get one as it might not be the right fit for you.
If you are between 5 ft 6 and 5 ft 9 then a harrow is recommended and if you are shorter than 5ft 6 inches, manufacturers have an academy-size bat available for purchase.
If you are shorter still, then you would be well advised to investigate the option of a junior bat.
