MMA is divided into weight classes, not height classes so, unless you are really heavy in proportion to your height, what's the problem?

Um, you're about six feet tall. That's not "short".

Ultimately it's about your height in relationship to your weight. Most Light Heavyweight (205lbs limit) and Heavyweight fighters are above six feet; most Lightweights (155lbs) and below are under six feet. So what's your weight? That's what you should be looking at.

I am just 172, don't be sad .....

Is this suppose to be funny?

I am 185 cm and i have 188 cm reach, am i too short for MMA. Will guys who are 190+ laugh at my height and outstrike me? Do i even have a chance against them? I dont want to be called shorty
