Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the GoPro Hero7 Black and Nikon S640 side-by-side from the front, back and top in their relative dimensions. GoPro Hero7 Black has external dimensions of 62 x 45 x 33 mm (2.45 x 1.77 x 1.3″) and weighs 116 g (0.26 lb / 4.09 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
GoPro Hero7 Black is 14g lighter than the Nikon S640 but we don't think this will make a significant difference.
Weather Sealing
With its weather-sealed body, we believe that the Hero7 Black has a big advantage over the S640 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Nikon S640's 2.70" LCD screen is slightly larger than GoPro Hero7 Black's 2″ screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
