Creating banner

[JamieH614]

I am working with a graphics person to design a branded banner and wanted to know what dimensions and resolution requirements you have to ensure it fits and looks good. Thank you

Hello @JamieH614 ,

Generally speaking, as long as the banner isn't more than 1200px wide, you won't need to worry about compression affecting the quality. Email templates are generally 600px wide, however, they can go as low as 300px or up to 1200px, depending on the width you set for your sections. I would recommend also recommend taking a look at this article on preparing images for upload, as our system will automatically compress any uploaded images that are more than 1200px wide.

Some other important things to keep in mind:

• There's a file size upload limit of 5MB, so if the banner is larger than that, it'll need to be reduced in size. See this article for more info on file types hosted in the Library, and other technical functions.
• Mobile email apps will try to make an image fit within the mobile device's width, while still displaying the image as close to its original, metadata resolution / sizing. This means that on phones especially, banner images that are particularly short in height may become very thin / small compared to images with more equal dimensions. If you're wanting the banner to appear well on mobile apps, your designer will want to keep the height to width ratio from being too extreme. See this article for advice and guidance regarding mobile email displays and image sizing.
