I have finally have some contact prints of 14x17 and 16x20 sizes that I want to hang them on the wall.

What frame size do you use for these sizes? Frame Destination does not even have cut mat boards of 14x17 and for 16x20 they have frames of 20x24 and 24x28. Do you have to tell them the exact sizes of your prints when you order as the film size is about about 1/4" short on each side?

The subject matter is landscapes and seascapes.

Thanks.
