Book covers

You can use this tool to add a layer to your cover art to give you an indication of where to place text and images. Please note that every platform may have its own cover calculator, so while the cover dimensions/art may work for Amazon's platform, your cover may need to be tweaked slightly if you use a different platform, such as Ingram or BookVault. Although, this tool will give you a good starting point.
