Paper Sizes Guide, UK Flyer & Poster Sizes in CM & Inches, A3, A4, A5 & A6

Hello! Hollie here. I’m one of instantprint’s Personal Artworkers, and I’d like to share our quick size guides with you to help you make your design print-ready.

Our team often get asked questions about paper sizes and stocks. Commonly, we see queries such as ‘is A3 bigger than A4’, 'what is A4 size in px' and 'what size is my print with bleed'. So, we've taken the time to craft an entire page dedicated to all things size!

Print Sizes in mm

The table below is based on printing a portrait document at 300dpi (dots per inch) – meaning it’ll print in really high quality. You can use these measurements to set up your document in your preferred design software program based on what size product you want. We've also included the paper size in pixels further down in this blog to help!

To convert your paper size to centimetres, simply divide the mm values by 10. 85 x 55 mm is the same as 8.5 cm x 5.5 cm.

Size Name	Size in mm (without bleed area)	Size in mm (with bleed area)
Business Card	85 x 55 mm	91 x 61 mm
DL / Comp Slip	99 x 210 mm	105 x 216 mm
A7	105 x 74mm	108 x 77 mm
A6	148 x 105 mm	154 x 111 mm
A5	210 x 148 mm	216 x 154 mm
A4	297 x 210 mm	303 x 216 mm
A3	420 x 297 mm	426 x 303 mm
A2	594 x 420 mm	600 x 426 mm
A1	841 x 594 mm	847 x 600 mm
A0	1189 x 841 mm	1195 x 847 mm
Roller Banners	800 x 2000 mm	806 x 2006 mm

A Quick Guide to 'A' Sizes

The table below compares the different A sizes available for printing, giving you an idea of how big your finished print item will be once it arrives. Many people are aware of the size of an A4 sheet of paper, so it may help to picture A4 paper size when thinking about the aspect ratio. Be sure to measure your desired advertising space before printing to ensure your print fits the space.

Getting to Know 'px' Sizes

Sometimes, when designing your print, you may come across px or pixels. A pixel is the smallest unit of a digital image and is a tiny square or rectangle that contains a specific amount of digital information, representing a specific colour or brightness level. Some people choose to work in pixels as it can help when looking at the quality and clarity of images.

At instantprint, 'A' sizes are the most common way our customers set up and refer to their print, so if you're presented with a new width and height choice, we know it can be confusing.

If you ever need to create a design in pixels and find yourself wondering, for example, what an A4 paper size in pixels is, simply use the table below and set up your design using the converted measurements from mm.

We name our exhibition stand sizes in numbers like this because of the amount of panels in each one. All of our stands are split into 3 sections (2 are not fully visible) and the middle section is split depending on how big the stand is.

As exhibition stands are a lot bigger than our other products, we need the resolution to be set at 150dpi.

Other Considerations

GSM

GSM stands for ‘grams per square metre’ and refers to the weight of the paper. The heavier the paper, the higher the number of grams per square metre – and, generally, the higher the perceived quality of the stock.

Choosing the right GSM paper for your printed materials is essential so, to help make sure you’ve got everything you need to make an informed choice, we created this quick beginner’s GSM paper guide and a guide to paper weight to get you started.
