The A Series Paper Size Guide

So, what is the A4 dimension in cm? How do I know A4 in mm? How many A5s are in an A3? All of the answers to these and other questions can be found right here. However, if you simply need a brief size reference, scroll down to our paper size chart to refresh your memory.

On the surface, paper sizes may be a bit perplexing. However, if you understand what they represent and how they connect to one another, you’ll be pleased to learn that it’s all quite easy.

The ‘A-Series’ Size 

You must already be familiar with the standard A4 size. It is the size of paper that your standard home printer uses, and the size of paper that is universally accepted in schools, universities, and businesses for day to day pronouncements. The A4 page dimension size is a globally recognised standard. This implies that regardless of your location on the planet, an A4 Perfect Bound brochure, for example, will always be an A4 measurement. 

This ratio is unusual in that it retains its aspect ratio when folded in half lengthwise. If you cut an A4 sheet in half along its longest side, you will get two A5 sheets. What is A0 size? You might wonder. When folded in half, A0, which is intended to have a surface area of 1 square metre, produces an A1 page size. This then becomes an A2 piece, and so on. Each successively numbered size is precisely half the size of the one before it. 

GSM 

The density or thickness of the paper is measured in GSM (grammes per square metre, often known as g/m². It is based on estimating the weight in grammes of a sheet of paper that is precisely one square metre in size. Paper with a greater GSM is often thicker, making it more difficult to wrinkle or tear.

What Makes The ‘A-Series’ So Special? 

• What makes the ‘A-Series’ so popular and special is that the longest side of each paper size is half the length of the shortest side of the following paper size down. This offers two advantages. The first is that if you fold or cut an A3 sheet in half, you’ll end up with an A4 sheet.
• The second feature is that all of the paper sizes have the same aspect ratio, which is very helpful for scaling up or down artwork. For example, if the picture quality is acceptable when enlarged, you may use the same artwork for an A5 flyer and an A4 poster, saving you time from having to duplicate the same piece of artwork for two separate projects.
• The A-Series also allows your print budget to be maximised and waste reduced as you make the most efficient use of paper. If your work is bigger than A4 (210mm x 297mm) but not quite as large as dimension of the A3 paper(297mm x 420mm), for example, 297mm X 297mm, we must still use an A3 sheet of paper, with the excess trimmed off and recycled.
• These standard sizes are also used by dispensers and display frames for posters, brochures, pamphlets, and leaflets. If you decide to use your printed item in a display at your workplace or at an exhibition, it will appear nice and sit properly. If you submit your printing to a third company to display, there’s a better chance it’ll work with their system as well.
• Finally, envelopes utilise a measurement method that corresponds to these paper sizes, ensuring that they can be delivered in the mail quickly and cheaply once printed.
