Ultimate Guide to Paper Sizes: From A0 to A7
We know that size matters. That’s why our paper size guide is here to help.
The first step to printing your designs is understanding what space you’ve got to work with, and we don’t want confusing print terminology to hold you back! Let’s dive in and compare some of our popular paper sizes…
Overview of Paper Sizes
A0-A3: Despite having the lowest numbers, these sizes are the largest of them all. Available on products like Posters and Display Boards, these sizes are a great option for stand-out signage.
A4: The most common (and recognised sheet of paper), A4 can be your go-to for prints like Letterheads, Perfect Bound Documents and Giclée Art Prints.
A5: From Flyers and Invitations to Menus and Notepads, this size is great for portable print.
A6: If you’re planning on designing your own range of Greeting Cards or Postcards, don’t underestimate the power of A6. It may just become your new favourite paper size.
A7: Small but mighty, we offer this size on Greeting Cards, RSVP Cards and more!

Understanding GSM
GSM. It may sound like a fancy term, but it’s actually quite simple. GSM stands for grams per square meter and it’s a measure of paper thickness. The higher the GSM, the thicker the paper.
Different printing projects require different paper weights. If you’re printing a brochure that needs to feel sturdy, you’ll want to use a paper with a higher GSM. Meanwhile, if you’re printing a large batch of flyers, a thinner paper with a lower GSM may be more cost-effective.
Top tip: A good way to decipher what you’re after is thinking about your printer paper at home. A standard piece of paper is usually around 80 GSM.
