Business cards have become thoroughly optimized as of late, and there is a pretty good chance that you would not have to make nearly as many decisions while having them made because you can just follow the best practices that have been established. There is so much precision in the standard business card design that it has been perfected all the way down to the thickness of the paper that the text will get printed on! Some are tempted to forge their own path and try to become trendsetters, but that almost never ends up going the way that they expected it to.
The truth of the situation is that attempting to figure out how thick your business cards should be would just be a longer route to achieving the same answer that everyone else has already taken as gospel. While Black Metal Kards might have a different set of requirements, paper based cards are almost always going to work best if they are within the fourteen point to sixteen point card stock range. Anything thinner or thicker would result in suboptimal business cards, so you shouldn’t waste your time trying to come to this conclusion when it is already waiting for you to scoop it up.
If you still want to see for yourself why these two thickness options have become standardized, just take a look at card stock that is of a different girth. Cards that are printed on twelve point stock are floppy rather than firm, and eighteen point card stock is so thick that it seems overly bulky within your pocket. There is no need to innovate when there’s nothing left to innovate for.
