Handle size and width is a personal preference. The following is just a recommendation.
In general our round handles are universal fit, along with our 48" curved ash handles.
Our full size 39" hickory handles are for larger hands and people who prefer a stout feeling handle.
Our 39" lightweight handles are for smaller hands and people who prefer a nimble, yet strong feeling handle.
Suggested handle length:
If you are 6' (152 cm) or taller, we recommend a 48" handle
If you are under 6' (152 cm) tall, we recommend a 39" handle
Suggestions for deciding between Full Size or Lightweight:
*Measure your hand (in a flat position) from the base of your wrist to the tip of your middle finger.
811/16" (22.1 cm) and longer, we recommend a Full Size handle
81/2" (21.6 cm) and shorter, we recommend a Lightweight handle
