I see the problem, you aren't sure of weights so I'll help. If we start at 1/4oz, and go by 16ths the next weight would be 5/16oz, then 3/8oz, 7/16oz, 1/2oz, 9/16oz, 5/8oz, 11/16oz, 3/4oz, 13/16oz, 7/8oz, 15/16oz and 1oz. If that is too much just got by 8ths and we have 1/4oz, 3/8oz, 1/2oz, 5/8oz, 3/4oz, 7/8oz, and 1oz. So a rod with a range of 3/8oz to 1oz will handle everything from 3/8oz to 1oz but in reality it will probably be ok with 1/4oz up 1.25oz but you would have to try it first. As someone already said, don't get caught up too much with the weight range, it is meant as a guide to help you choose the rod you need, for example, if you are throwing mostly weightless worms and smaller baits that are like 1/2oz and under then you would select a rod rated like 1/4oz to 5/88 which is slightly more than 1/2oz and that would be a medium power. Most medium power rods run in the 1/4oz to 5/8oz range and most medium heavy run 1/4oz to 3/4oz, but there are some that run up to 1oz. Jigs and worms around cover you almost always opt for a MH rod, if you are fishing jigs and worms that aren't heavy and are in open water or sparse cover, you can get away with a medium power and that is all you need to worry about.
