PaperSizes is a simple, free resource for finding the international standards for paper sizes. In their spare time, UK Designer Rob Lafratta and developer Richard Franklin wanted to create a tool for themselves and others who needed quick access to paper sizes. With a clean and minimal interface, it’s a very useful tool on desktop computers and mobile devices. In total, lists dimensions of over 250 international paper sizes in mm and inches!
