So I had a lot of free time today and I started playing with Illustrator creating various documents with different page sizes. And then I thought I would measure a document size at 100% zoom, to see if it was the same size I had selected when creating a new document. For example: I created an Illustrator document with these measures: Width: 2 inches, Height: 2 inches. And then I zoomed 100% and measured the black square. and to my surprise it measured: Width: 1.3 inches, Height: 1.3 inches. Why? Does it has something to do with my display setting?
