What are you guarding against? The size is one factor--another is shape. If you are guarding against a surface and have wave action, a spherical fender is better than a cylindrical one--it rolls vertically <i>and</i> horizontally.
The cylindrical rope-tube ones Schnool showed you can be adapted to roll horizontally <i>or</i> vertically, but not both.
I have the orange spherical type. They are great for floating docks and for rafting. The hull shape keeps them from riding up. They are not as good for fixed docks where you need to guard against vertical pilings, as I realized when I took my boat down to the Chesapeake last weekend. I'm going to have to supplement them with some cylindrical type for that.
I use the round type that Dave shows for boat to boat or for random docking and they work very well. I use the cylinder type at my slip and they are permanently attached to the dock. Try the round type, I think you will like them better but as stated above not good for pilings.
I use six of these and they work well for docks and raft up. Also Taylormade sent me some new valves, free of charge, when two of the old ones started to leak.
Tie them ( the long ones ) on both ends and use them horizontal. They usually roll instead of rub. One more line to keep from losing them. Keeps them in place on a piling.
