The Ultimate Poster Size Guide

Posters are without doubt the best way to make some noise about your business. But just how big do you need to go? The perfect poster size depends on where you’ll be advertising and what you want to say. Here to give you an idea of what each poster size is suitable for, we’ve created a handy guide so you can make a poster that’s just the right fit.

A3 Posters

Dimensions: 29.7 x 42cm / 297 x 420mm / 11.7 x 16.5 inches.

A3 Posters are double of your standard A4, making them ideal for advertising indoors. If you’ve got a sale in your shop, want to promote a new product or even if you want something for your bedroom wall, A3 posters will do the job. Even better, our online poster maker lets you customise free templates to create an eye-catching design in A3, whatever you’re promoting.

A3 posters are available on economy 150gsm, standard 250gsm or premium 350gsm Silk Paper which are all suitable for indoor placement, making it the most cost-effective of our smaller posters.

A2 Posters

Dimensions: 59.4 x 42cm / 594 x 420mm / 23.4 x 16.5 inches.

A2 Posters are one of our most versatile sizes. Small enough to be placed in shop windows or behind receptions and large enough to be seen at a distance, they’re made for multiple uses. Take them with you to exhibitions or place them on a wall outside your venue to draw in the crowds.

A1 Posters

Dimensions: 84.1 x 59.4cm/841 x 594mm/33.2 x 23.4 inches.

A1 Posters are big, bold and perfect when you want to make a poster with a statement. Ample space and a huge surface area means there’s plenty to play around when it comes to design. You could showcase your price list, list the times of performers at your event or simply present one bold image for a dramatic poster that captivates attention.

These posters are also ideal for popping inside an a-frame [link] and leaving outside your shop to attract passers-by if you’re busy running the show inside!

A0 Posters

Dimensions: 118.9 x 84.1cm / 1180 x 841mm / 46.9 x 33.2 inches.

If you want a poster that refuses to be ignored, A0 Posters are for you. Choose from 250gsm Silk, weatherproof 220 or 400 micron PVC for outside placement and maximum exposure. Fundraisers, gigs, business launches or any message your business is proud of will be amplified by this larger than life poster.

40 x 30 Posters

Dimensions: 101.6 x 76.2cm/1016 x 762mm/40 x 30 inches.

Just smaller than an A0 Poster, our 40 x 30 size definitely has the potential to wow. Using one of our free templates, it’s easy to make a poster that informs and impresses in equal measure. Whether it’s the opening night of your new restaurant or a description of your latest stock, 40 x 30 will get the message across. We recommend using a combination of larger fonts and smaller text for a well-balanced and effective campaign. Check out the science behind the perfect poster for more info!

60 x 40 Posters

Dimensions: 152.4 x 101.6cm / 1524 x 1016mm / 60 x 40 inches.

Larger than life and ready for action, 60 x 40 Posters are the biggest size we offer. These posters guarantee exposure and one of the most effective marketing tools out there. Bus stops and outside display stands or anywhere people are passing are perfect places to house your supersized advert.
