The pleasing maths of paper sizes

The dimensions of paper sizes aren’t random. Each size is based on the square root of two. This is why two pieces of paper with the same proportions can fit perfectly together when placed alongside one another.

Need A3 sizes but have a tall stack of A4 sizes in your stationery drawer? Simply place two A4 sizes next to each other and you’ll have an A3 size piece of paper.

But this maths fact is more than just a handy tip for resourceful people looking to make the most out of their current paper collection. Because A-series paper sizes have the same proportions, documents or artworks can easily be resized to fit onto any paper size without distortion.

What to do when your project requires a non-standard paper size

While the paper sizes within the A-Series are extremely popular, that’s not to say that they are your only option for printing.

At Snap Print Solutions, we understand that not all projects can be condensed into a restricted size, such as large format digital printing. If you require a unique paper size for your printing project, get in touch with your local Snap Centre to find out how we can bring your vision to paper - standard or otherwise.
