Here's a quick tip regarding the function of artwork sizing known as Scaling.
When you Scale a graphic proportionally, you're either increasing (up) or decreasing (down) its overall surface area (Length x Width). To increase sizing of an image we ALWAYS scale proportionally, rather than stretch in a single direction, in order to maintain the visual integrity of each graphic.
Aside from the visual importance of scaling proportionally, the increase or decrease in surface area will have a direct effect on pricing. Sometimes the change is negligible and in other cases can be very significant.
