And? Assuming you meant 60 square meters since "an area of 60 meters' is meaningless. Laying it out full scale should not pose a problem in a reasonably modern version of Corel and, despite any advice to the contrary, that's exactly what you should do. Scaling down merely hides problems since a scaled version, say 1:10, is lacking 90% of the information required for the completed work. Even with vector objects you can miss various geographical features. It's just fine to scale down in order to print, send proofs, etc. But don't scale up in order to produce the finished work. "That's what everyone does!" 'everyone', whomever they might be, will cry. To which you should say "If 50 million people do a stupid thing, it's still a stupid thing."
