Choose from a selection of high-quality paper weights, including our robust 180gsm stock, which provides the perfect balance of durability and premium feel. To further enhance your design, we also offer various finishes such as silk, gloss, and matt, alongside professional lamination options to protect your work from wear and tear.

The A3 size is a powerhouse for visual communication across a wide range of industries in the UK. Small business owners and retailers frequently use an A3 poster for window displays and point-of-sale promotions because the 297mm x 420mm dimensions offer ample room for bold headlines and striking graphics. For educators and students, it’s the go-to format for classroom displays and academic posters that need to be legible from a distance. Creative professionals also favour this size for art prints and portfolio showcases.

A3 poster printing frequently asked questions
Find everything you need to know about our A3 poster printing services below. We have compiled these answers to help you navigate our options and ensure your final product meets the highest professional standards.
An A3 poster measures 297mm x 420mm (or 11.7 x 16.5 inches). This makes it exactly twice the size of a standard A4 sheet of paper. It’s an ideal medium-sized format that provides enough surface area for complex designs while remaining compact enough to be posted through standard letterboxes when folded or rolled into tubes for easy transport.
We specialise in fast poster printing A3 size to help you meet tight deadlines. You can choose from our 2-day or 5-day production schedules depending on your budget and urgency. If you require your prints even faster, our loose sheet printing option allows for next-day delivery if ordered by 1pm Monday to Friday. We also offer free UK courier delivery on all orders over £30, ensuring your marketing materials arrive safely and affordably.
For most promotional and display purposes, we recommend our 180gsm paper. This weight is significantly thicker and more robust than standard printer paper, making your poster more resistant to creasing and tearing.
If you’re looking for something even more substantial for long-term outdoor use or premium displays, we also offer foam board mounting and lamination to provide extra rigidity and a high-end professional finish.
Yes, one of the biggest advantages of using Doxzoo is our total flexibility. We have no minimum order quantity, so you can order a single poster print for a personal project or a one-off gift. Conversely, our high-capacity digital presses can easily handle bulk orders of 1,000 or more for large-scale commercial events, ensuring consistent quality across the entire print run.
To ensure the best possible results, we highly recommend uploading your artwork in PDF format. This preserves your fonts, margins, and image resolution. However, our user-friendly platform also accepts Word and PowerPoint files. Before you finalise your order, our online previewer allows you to check exactly how your design will look on the page, giving you peace of mind before we head to press.
The choice depends on where your A3 poster will be displayed. A gloss finish makes colours appear more vibrant and saturated, which is excellent for photography and high-energy advertisements. However, if your poster will be placed under bright indoor lights or near windows, a matt finish is often better as it reduces glare and makes text much easier to read from different angles.

180gsm paper is thicker and more robust than standard paper, ensuring your posters are less prone to tearing, creasing, or folding. This makes it ideal for long-term displays or posters that may be handled frequently.
