You can test your image quality in our File Quality Check tool.
What if my source image is low quality?
Unfortunately, when the quality meter indicates your image is too low in resolution, we cannot print it as a poster. Additionally, customers are advised to carefully review and approve proofs of their images during the ordering process, as all custom-printed materials are non-returnable and non-refundable. This policy ensures transparency and sets clear expectations before production.
This often happens if you try to use an image taken from the web. Web images are very poor quality, what looks good on a screen will not look good printed out, even small, let alone as a large poster.
An image needs to have at least 75 dpi (dots per inch) in resolution at the desired print size to ensure satisfactory results. This is the minimum threshold, and higher resolutions are preferable for larger prints to avoid pixelation. We have a great guide to resolution and file preparation here.
Try finding a higher resolution photo or image to start with. Once you have a high enough resolution image, the order page will allow you to continue and even tell you the largest recommended size for the image. Alternatively, you can adjust your print size to better match your image’s current resolution, which ensures clarity and avoids pixelation. Minor digital enhancements may improve the image slightly but cannot create details absent in the original file.
It's a common next quesiton for someone to say "my image is too low quality, isn't there something you can do?" If there was a way to magically enhance your image, we would sure do it. But unfortunately you cannot "create" pixels that don't exist. That is what causes blurriness. A tiny image can't be enlarged to giant proportions if it doesn't have enough pixels to begin with.
