Here is how we compute dimensions – we gang all your files up together and draw a box around the “black” part – the images and text. Now we know the length and the width. We multiply these two numbers together and this is your square inches total. We then multiply this square inch number by your square inch price of $0.62/sq inch or $0.67/sq inch.
9″ x 8″ is your “black part”
9” x 8” = 72 sq inches x $0.67 = $50.40
If your file has crop marks, we measure outside the crop marks. So if you don’t need crop marks, consider leaving them off to save a little cash.
