The difference is mainly based on the Geographical Area the networks cover. Anything under One Square KM can be considered as LAN. Where as a WAN which connects lot of LAN's, spans across the whole planet. The Internet is also a  WAN.

LAN is a small network, says a company's inside network, that is LAN,

WAN is a large network, when more than two companies are interconnected and communicating, that whole network is considered as WAN!!
