Query: Great dry bag, but poor size info

The quality of this bag is fantastic for the price. I don't have much doubt that it will keep its contents dry.My only complaint is that it took me 3 orders to get the right size for my needs. The measurements in the description don't quite describe how huge this bag is. I returned it and bought a Size 30 which was again too big.I returned that too for a size 20, which is still a bit big for my tastes but I was not able to return it for a smaller size.
