Height to Width Ratio

Look at the design, and check the shape of the image, ask yourself the following questions:

Is the image portrait, landscape or square?
If it’s portrait or landscape, is it really long and narrow, or short and fat?
If it’s square, how square is it? Very square, or a little bit square

Size & Layout Location

These two points are related because you need to think about where the image is going in order to determine maximum and minimum image dimensions.

As a general rule of thumb, we want the image to be as small as possible for increased performance, but we never want it to appear blurry on any device, which is where the location comes into play.

Rules
Minimum width : 320px (Same as smallest iPhone)
Maximum width : 1200px (Same as maximum width of website)

Layout Locations
The image can be present in a number of different layout locations, i.e. in 1 col, 1-1 and so on. For each scenario the minimum and maximum widths may change.
