When I started selling posters I began with A3 size posters for the first six months or so. They seemed like a good moderate size to offer whilst being affordable and practical to transport.
As I was designing posters inspired by vintage advertising, I was convinced I needed to go bigger and offer them at A2 or ideally A1 size—the size that most posters actually are. The practicality of posting and storing them was what delayed me from doing so.
Then someone (I forget who) made a passing comment that they would buy one if it was smaller. It got me wondering if the opportunity was in fact to go smaller and as it was easy to do, I got a set printed at A4. Immediately they sold better than the A3s, and continue to do so on this site.
I now realise why. A few months ago I was browsing posters in a store in Brussels and I liked a particular design. However it was only available in A1 and I didn’t like love Brussels enough to want it that big! Had there been a small version of the poster then that shop would have had a sale.
When selling decoration or wall art you’ve got to assume that most people already have plenty of things on their walls, so you need to fit in around that, rather than demand to take up a whole wall.
This shrinking idea has continued to bear fruit when I launched a product that featured designs at 6x4 inches in size (or postcard size). The product is three different ‘mini posters’ in a frame and is something I sell at markets. It has proven to be a popular, although not as successful as the A4 size.
Of course it’s worth discovering if people do want larger sizes too. My solution to that has been to use Fy, a third party print-on-demand service, where people can by versions of the posters up to 60x80cm in size (and I don’t have to get involved in the actual printing).
