It's about Tall.

American Tall is quickly establishing itself as a leading brand of men's tall clothing. Our focus is on creating quality and fashionable clothes that fit both your height and your width.  

On average American Tall clothing fits men who are 6'3 to 7'1 with a Medium to 2XL build.  This means if you're over 6'2 and are slim and tall, or you're solidly-built and tall, our clothing will work for you!

With American Tall you don't have to choose between length and width. Finally, you can get style and fit.
