If reading the title confused you a little then good, it confused me the first time someone said it to me. Thankfully it’s pretty basic and once I explain it, you’ll just do it subconsciously. If you have been wearing suits awhile – you may already be doing it.
The size of your tie’s knot should be in proportion to the size of your collar and vice versa. In layman’s terms; big & thick ties for large collars and skinny/thin ties for small collars.
The style in which you choose to tie your tie matters. I haven’t worn my tie in any other way except a full Windsor for over five years. I find it perfect for me as when I choose to wear a tight fitted shirt with small collars and a tie bar, my skinny tie and Windsor knot looks fantastic. Equally as fantastic are my TM Lewin big wide collar shirts with my thick standard ties in a Windsor knot. However, I have seen some people doing some crazy knots, making patterns out of it all, this is fine if it suits you but make sure that you haven’t wrapped your tie around your knot 15 times on a shirt with small collars.
If you are unsure as to whether your tie’s knot will be big or small then simply look at the width of your tie. The more material in the tie the larger your tie knot will be.
