Despite the digital age slowly taking over, paper, and the most common A4 paper size in particular, is still in huge demand. The global paper products market size was estimated at USD 268.8 billion in 2018 and is expected to register a CAGR of 0.3% from 2019 to 2025. Although this growth may not seem huge, when considering the sheer volume, it becomes obvious that the printer & copier paper industry is still a huge money maker.

Before running to stock A4 size paper, A4 sheets, A4 documents, and all other paper types, there are a few things to consider:

What is A4 paper size?

Many people do not know what the A4 size in inches or A4 size in cm is. Nor do they understand that A4 envelopes size, A4 print size, A4 letter size, A4 page size are all the same size. So, to clarify, A4 refers to the size of the paper — 21 x 29.7 centimeters, 210 x 297 mm, or 8.27 x 11.69 inches. This is different to A4 A5 A6 paper sizes, which become smaller as the number goes up or bigger as the number goes down.

A3 vs A4 paper

A3 and A4 paper are different sizing options for normal paper, including A3 or A4 white paper and A3 or A4 colour paper. A3 paper is exactly double the size of A4 paper. When catering to your customers, you should consider stocking both, however. A4 paper may be standard, but A3 is better for mind maps and presentations at work, or for large class posters at school. Additionally, A3 paper sizes are perfect for printing poster advertisements. Stock paper in a variety of sizes to cater to all your customers printing and paper needs.

What is GSM?

Another aspect of printing paper that is often ignored is paper thickness. This is of paramount importance for your customers — not only because they will require different thickness, or grams per square meter (GSM), for different projects, but also because paper thickness is indicative of quality in paper packaging. For this reason, be sure to have a large supply of different thickness paper, including 80GSM paper and 100GSM paper.
