Speedo Guards vs Andis Guards Sizing. When applying this set to wall guards just use the Guard # and that is how many eighths of an inch you will leave on the scalp. So for example a number 4 guard is 4/8ths which is exactly 1/2 inch. Please leave a comment if you have any questions I've been barbering professionally for two years now so my understanding is a lot better then when I made this video.
