On a spring that is 26 inches eye to eye on center and a single axle trailer you will want the hangers to be up to 1/2 inch less than the spring length so 25-1/2 inches on center between the front and rear hangers.

Thanks so much for that info, and to replace your current leaf springs that are 24 inches apart from center eye to center eye, you want springs that are slightly shorter because over time they flatten out. So for replacements I recommend 23-1/8"…
