How do you measure oar length?
3 min read
Asked by: Todd Thao
Measure the distance between the center of the port and starboard oar sockets, which hold the oar locks on each gunnel. This is called the “span” between the oarlocks. Divide the span by 2, and then add 2 to this number. The result is called the “inboard loom length” of the oar.

Sculling: You should have a comfortable amount of handle overlap through the middle of the stroke. If it feels like you have too much overlap, decrease the inboard dimension or increase the span. Remember that decreasing the inboard will also increase your load.
