Just about any site mentioning Raspberry Pi computer will say it's credit card sized. Yes, length and width of Raspberry Pi exactly match those of a credit card, but a creadit card is 0.76 millimeters thick and Raspberry Pi is 17 millimeters thick and so it's 22,4 times thicker.
In my native language being 22 times thicker than a credit card disqualifies a thing from being credit card sized even when length and width match those of a credit card.
In English what exactly does credit card sized mean? Does it include all dimensions or only length and width?
