Chest measurement is a poor metric for a TQ. Chest size is measured around the entire circumference of the chest. You're not asking a TQ to cover your back..only your front and sides. You didn't specify if you've tried both sizes. I used to believe I needed a wide because the forum overwhelmingly recommended it when I was new. After using a standard I feel it's worth pointing out to newbies that you can be just as comfortable in a 50"
