Dimensions & Format

To make sure your designs are printing well on products, you’ve got to keep Dimensions and Format in mind.

The article below will cover everything you need to know about:

• Dimensions

• Product Dimension Requirements

• File Type

• Color Profiles

Dimensions

A good rule of thumb is that big, high-resolution files make the best prints. Now when we say ‘big’, we're really referring to resolution, not the file’s size.

There is a major difference between file size, which is measured in bytes (like megabytes MB) and resolution, which is measured in pixels. When you’re printing work, it’s the pixels that matter.

Product Dimension Requirements

To ensure a good quality print, each of the products on our site has a file dimension requirement; that is, the minimum resolution a file needs to have to be enabled on a certain product. You’ll find the resolution thresholds for all of our products below.

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). Images above 300Mb, or 13500x13500 pixels in size, cannot be accepted on the site due to the heavy load they place on our servers.

Please also note that DPI and PPI don’t have any effect on your final uploaded image.

File Type

When uploading your files to Redbubble, we can only accept JPEG, PNG, and GIF. TIFF and PDF files won't work correctly.

Color Profiles

The CMYK color profile works best for print while sRGB works best for viewing designs on the web.

For the best of both worlds, you want to design your work in the CMYK format. Then before you upload, you want to convert the finished work into the sRGB color profile.

Color profiles are a really tricky topic, so we’ve written up a detailed explanation in the article Designing in CMYK vs RGB on our blog. Check it out!
