How important is Height in a relationship?

Girls, this question is to you. So basically asking for a friend(20M) Ahem. My buddy who is an amazing guy stands between 5'5 to 5'6 (167.3 cm) and is curious to know , is height an important factor for you in relationships ? I've seen girls in my circle crushing over those tall dudes. So what's your take and suggestions? What's the shortest height you have dated or been in a relationship with ? Be brutally honest, no sugarcoaing please. Even boys are welcome to share their experiences and tips. Let's keep it real this post could be a goldmine for someone searching this topic down the line(thanks to my friend, of course)!
