    Mine isn’t 4mm but it’s 3.4mm and I did not size up.

    my finger and first ring set is 4.5. Thin bands. I have a really thick white gold ring as well that I wear and it is a size 5.25. The wider the band the bigger it needs to be. The rule of thumb is a least a half size bigger then or normal ring size depending on how wide the new band will be. I think mine is 5mm and wider at the widest point. 

    That proved to be true for me. We went up a half size in the beginning and it was still too tight for my liking. I say, go up a half size, I think it will be good.

    @politicsgal:  mine is a half eternity. If I had a full I would have probably sized up to be safe too!

    I would size up. My ering is 1.8mm and fits how you describe, and I have a matching 1.8mm wedding band that is the same size and both together are snug when my hands are hot and swollen. I’d definitely size up for a 4mm band by a 1/2 size if you plan on wearing your wedding band on the inside (closer to your palm), maybe 1/4 if you put it on the outside
