What image sizes are recommended for my booking website

From SimplyBook.me


For the best results, use pictures in JPG, GIF (non-animated), or PNG formats with a file size under 2MB. Adjust the image size based on the screen it will be displayed on.
Aim for a ratio of about 1:1.5 for banners and 1:1.7 for service, service providers service categories, etc., and be cautious about placing important details near the edges of the image, as they might get cut off due to screen resolution.
