Dimensions


When it comes to uploading your images to Redbubble we prefer big, high-resolution original files which make fantastic prints. And when we say big we're really referring to the number of pixels in a file.

The file size (in MB) is actually not the best indicator of whether a file is suitable for printing on Redbubble. In the example below, the image has is 3.04 MB (quite small) and a resolution of 3779x1974 (reasonably large). Kooky, right? A file that may look quite small is actually totally suitable for printing at large sizes, all because of those pixels.

Below are the resolution thresholds for every one of our products. Take note that larger sized designs will be scaled down to fit the smaller dimensions, whereas smaller designs will not be scaled up. As this handy video explains, our uploader will stop a design from being added to certain products if it doesn't meet their minimum requirements. If you'd like to use a single image file for every product, we'd recommend starting with 7632x6480 pixels (suitable for our king size duvet covers). That way it'll be big enough to fit every product we offer!

Gallery Boards:

The ratio for your work is decided by our systems when you upload an image. It then analyzes the image and applies the closest ratio. If you would like to change the ratio for your image you will need to upload an image at the recommended ratios.

For more information on gallery board sizes, check out Uploading for the New Gallery Board.  

The best way to do this is to use the Photoshop templates to export image at the perfect size. Alternatively resize your images as per the following preferred aspect ratios & dimensions:

  • 1:1 (square) = 3060 x 3060 pixels
  • 1:25 = 3360 x 4260 pixels (this is for portrait orientation. Please invert the dimensions for landscape uploads)
  • 1:4 = 1560 x 2160 pixels (this is for portrait orientation. Please invert the dimensions for landscape uploads)
  • 1:5 = 1260 x 1860 pixels (this is for portrait orientation. Please invert the dimensions for landscape uploads) 

This is what your screen should look like in Photoshop when you are setting your pixel requirements: 

Format

When uploading your files to Redbubble, we can only accept JPEG or PNG.

TIFF and PDF files won't work correctly and what's more it will make kittens cry, so please don't do that.

Color

Our garment printers only print in the CMYK format so we recommend designing in this colour spectrum as it will give you a better idea of how the final product will look. You will still need to convert to sRGB colour profile to get your works looking as glorious as possible on the site.

Bleeding and cropping

As with all professional printing practices, the actual printed product will often vary slightly from the online preview. We'd advise you to steer away from placing text or borders on the outer edges of the printable areas, as there will always be a small margin for bleed on all printed products. 

Other Important notes

  • Please do not manually increase the pixel dimensions of your image. We use the number of pixels in an image to determine which sizes are appropriate – if you change the pixel dimensions you will trick our quality control software – but the products will come out looking blocky and horribly pixelated. And not everyone loves that Minecraft look.
  • If your image size or format is not right, this might restrict you from saving your work to some products. We automatically determine which products your file can be used to create, so that we only ship creations that both you and we can be proud of.
  • Images above 300 MB, or 13500x13500 pixels, cannot be accepted on the site due to the unreasonable load they place on our servers. Keep 'em trim guys. 
  • Images can pass the minimum threshold for a product without being the same aspect ratio, which can lead to white space or parts of your image being cut off - it's a good habit to check the previews for each product to ensure that everything fits and make changes (add background colour, use tile feature etc) if needed!
