Paper, Envelopes, Sizes & Formats Selector
When working with paper and printers, it just makes sense to use standard sizes. Every time you go outside these standard sizes, you can expect dramatic increase in printing and shipping costs and it will be difficult to display in standard display systems. That’s why these standard formats exist. That said, you can usually take a standard format and make it more interesting by making it smaller in width or height, depending on your design concept, without additional printing cost. But this does not apply to envelopes, books or photographs. Any custom sizes are a lot more expensive.
