Banner images serve as headers, covers, and promotional graphics across websites, social media profiles, and email newsletters. Creating correctly sized banners for each platform ensures professional display without cropping or white bars.

Banner Design Principles
- Keep key content in the centre — edges may be cropped on some devices
- Use high contrast between any text and the background
- Keep text minimal — banners are viewed briefly before scrolling
- Use your brand colours and typography for consistency
- Test on both desktop and mobile — banners display very differently on each
