My right lat is significantly larger than my left and i don't know why. The only conclusion i can come to is that i play tennis and mostly use my right arm, but it just seems like to much of a difference for it to be b/c of tennis.
How should i even this out? What would be causing it?
I would say tennis could be a cause. Start using your left arm more and see if there is a change.
