Make your own Personalised A3 Stickers

Completely customise your own A3 stickers with us and we'll handle the professional a3 sticker printing and delivery to your door. All our large format stickers are permanent, so be careful what surface you are applying them to - if it is a wall, these stickers could remove paint when you come to take them off.

Get started by uploading your design onto our website, if you are a little stuck for ideas and don’t have a design then perhaps have a look online to find an image or picture you would like. Once you have your design, take a look at our materials. All our materials are professional which a high quality finish. If you’re looking for a paper based sticker then paper, cream textured paper and brown Kraft paper are a good place to start. Brown Kraft paper is 100% recycled while our traditional paper is vegan. If you’re looking for waterproof materials then A3 clear, plastic/vinyl and waterproof options are the ones for you.

If you have any questions about our materials, including waterproof A3 stickers, get in touch. We have a sample pack we send out to customers who need a little help choosing materials for their custom printed stickers - the sample pack has all the information you need. If there are any more questions about our printed stickers, pop us an email - our UK team always loves to hear from customers.

What can you use A3 stickers for

A3 stickers measure 297mm x 420mm, making them ideal for applications where you need maximum visual impact. Their generous size works brilliantly for promotional posters, retail point-of-sale displays, and event signage.

Many customers use A3 stickers as temporary wall graphics for exhibitions, trade shows, and pop-up shops. The permanent adhesive ensures they stay in place throughout your event, while the professional print quality makes your branding stand out.

For businesses, custom A3 stickers work well as window displays, directional signage, and safety notices. Choose our waterproof vinyl material if your stickers will be used outdoors or in areas with moisture exposure. 

Whether you are creating eye-catching promotional materials or practical signage for your workspace, A3 gives you the space to include detailed graphics, large text, and impactful imagery that smaller sticker sizes simply cannot achieve.

If you need multiple smaller stickers rather than one large design, explore our sticker sheets for flexible options.

Frequently asked questions

An A3 sticker measures 297mm x 420mm, making it one of the largest standard sticker sizes we offer. This generous size is perfect for posters, signage, and displays where you need your message to stand out from a distance.

Yes, A3 stickers work well outdoors when you choose our waterproof vinyl material. This option is weather-resistant and designed to withstand rain, sunlight, and temperature changes, keeping your stickers looking sharp for longer.

Start by cleaning the surface thoroughly and letting it dry completely. Peel back a small section of the backing, position your sticker carefully, then use a squeegee or credit card to smooth it down gradually, working from the centre outwards to push any air bubbles to the edges.
