## How do you know what size syringe to use?

Selecting needles by gauge size occurs by considering skin or hide thickness and the depth of the injection. The needle gauge is a series of numbers in which the lower the number, the wider the diameter of the needle. The higher the gauge number, the smaller the needle width.
