How to choose a shooting pad : 

The smaller sizes are very affordable and good for younger players or as something to start with.
If you will be doing mostly shooting than a small size will be good for you
If you are older and will be using your shooting pad a lot I strongly recommend a larger shooting pad.
The larger shooting pads are great because you have enough room to practice a variety of stickhandling moves.
Large hockey shooting boards also provide enough room for a full wrist shot and room to line up a few pucks for slapshots. Another great benefit of the pads are that they last a very long time
