If you are trying to measure your current leaf springs so that you can pick out the correct replacement ones you will want to measure from the center of the eye to the center of the other eye.

Typically springs will flatten out over time (around 1/2 inch), so you will want to pick a spring that is slightly shorter than what your current spring is. The amount of leaves isn't as important as picking out one the correct length and capacity.

I attached a help article on trailer suspension for you to check out as well.
