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 Hero9 Black and Sony W800 side-by-side from the front, back and top in their relative dimensions. GoPro Hero9 Black has external dimensions of 71 x 55 x 34 mm (2.8 x 2.17 x 1.34″) and weighs 158 g (0.35 lb / 5.57 oz) (including batteries). Sony W800 has external dimensions of 97 x 55 x 21 mm (1.97 x 0.87 x 2.13″) and weighs 125 g (0.28 lb / 4.41 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W800 is significantly lighter (33g ) than the GoPro Hero9 Black which may become a big advantage especially on long walking trips.
Weather Sealing
With its weather-sealed body, we believe that the Hero9 Black has a big advantage over the W800 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony W800's 2.70" LCD screen is slightly larger than GoPro Hero9 Black's 2.27″ screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
