When you are adding a price list item for a template in the Price List Setup window, ProSelect will display the actual print sizes available for that layout. These will be the sizes that will result from fitting the overall template (for a Composite Template) or the main image (for a Traditional Matted Template)  into one of your standard print paper sizes. For example, if you have a square composite template, then you will see sizes like 8x8, 11x11, 16x16 if you have print paper sizes of 8x10, 11x14, 16x20.

However, when you come to order that template (used as a layout), then the Place Order window only shows the original Print Paper Sizes (eg 8x10, 11x14, 16x20) rather than the resulting sizes.

Because this does lead to some confusion, we have changed the way this works as of ProSelect version 4.1. where the resulting sizes are now displayed instead. Image size dropdown and popup menus show the actual size of the layout rather than the print paper size that it is based on.
