Rules? There is one rule, yes, but I am guessing that there is almost no chance that you will ever come into a situation where it actually applies. Guidelines? Now we’re talking. There are a few general guidelines, and I am happy to pass them along.
First, The Rule: If you are wearing a shirt that has studs instead of buttons, your cufflinks must match the studs and be exactly twice the diameter of the studs. Period. End of discussion.
Now then. For the 99.934 percent of the time that you are not wearing studs, the guidelines mostly come down to our old friend Common Sense. First (and foremost!) the size and style of your cufflinks should play nicely with the size and style of your other jewelry – especially your watch. If you are wearing one of those unfortunate new Giant Wirst Monstrosities you probably want a cufflink with enough visual heft to keep up. Conversely, if you are packing a watch that has a more subtle design and size (think Skägen) then you should go with a smaller and cleaner link to balance it.
The size of your cuff counts, too. Some guys still go for the elongated cuff, and you dont want your links getting lost on a sea of fabric. At the other end of the scale we have the convertible cuff, with a much shorter haft than a traditional french cuff, and you dont want to bust out something that will hang off both ends or look like a pair of bad-sci-fi-movie prison manacles.
Interestingly, the size of your own self is not that big of a deal. People compare the links to parts around them, not your body as a whole. Unless you happen to be Andre The Giant’s larger cousin or something, body size is not something that is going to limit your choices.
