To make sure that your images have the correct size, it is recommended to use the following guidelines:
- Fullscreen backgrounds – 1920px/1280px jpeg;
- Fullwidth backgrounds – 1920px/w jpeg;
- Half screen inside content box – 500px/w jpeg;
- One-third inside content box – 300px/w jpeg;
- One-fourth inside content box – 200px/w jpeg;
If you are replacing an existing image and you are not sure about the size, you can check the dimensions of the old one from Dashboard/Media/Library.
