Hi,
If I want to build a website that’s full width (horizontal) and looks sharp on iPad air 2, what is the optimum site width? If I put a full width image, should it be the same width size as the size width to look sharp?
iPad Air 2 is retina, so you’ll need to upload your images twice as the size of what you want to show. If your images are already big, e.g., 1500px wide, you won’t need to increase that size because iPad will resize the image automatically and because the size of the image is large, it will look crisp on the iPad.
