There is a tendency among more established corporations to be rather conservative at any given point in time. A big part of the reason why that is the case has to do with the fact that these business almost never want to even think about rocking the boat in any way, shape or form since they would ideally prefer that their business practices remain more or less consistent with the ones that allowed them to attain this level of success in the first place.
This creates an opportunity for newer businesses to experiment and innovate, thereby creating a situation wherein they would get a much higher chance to break into markets that these better established companies are trying to maintain dominance over. Suffice it to say that opting for non-standard Metal Business Kards sizes can often result in you finding better alternatives to what is universally considered to be optimal. The standard business card size is 3.5 inches in length and 2 inches in height, but that doesn’t mean that it is necessarily the single best size that you can opt for.
Another size that is starting to catch on is 2.5 inches by 2.5 inches. This creates a 2.5 square inch card that isn’t rectangular at all, but rather has even sides which means that it is a square. Cards like this can be a highly effective way to make your company stand out because people will be intrigued by the unique dimensions. If you want to maintain the rectangular form factor of most business cards, you can try out other sizes such as 3 inches by 2 inches, 2.5 inches by 2 inches and others.
