The reason for that is just how much Raspberry Pi has strived to save money on the machine by using complex routing to keep things small and cheap.
The Raspberry Pi team don’t believe the design is going to change again unless they missed something. With that in mind, they revealed the final board is exactly the same size as a credit card, measuring 85.65 x 53.98mm.
Raspberry Pi has a very active community on its forums, and it didn’t take long for someone to print a 1:1 scale copy of the final design on a sheet of card. The images below give you a good idea of just how small this PC is going to be. Although once the ports have been added the thickness is obviously going to increase.
