GM cricket bat sizes
540 and 555 refer to GM blade lengths in millimetres, not two different player heights.

What to check on size
GM suggests considering a full-size bat from about 1.69 m. That is a different starting point from Kookaburra's chart, so do not transfer its adult boundary to every brand.
Compare the whole bat length as well as the blade. A shorter blade changes the shape and pickup without necessarily changing the size label.

These are catalogue references, not live stock matches. Prices, available sizes and specifications can change.
Ask before buying
- Which blade length does this model use?
- What is the finished bat's weight with its grip?
- Can I compare it with the next junior or adult size?
