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 Canon SX620 HS 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). Canon SX620 HS has external dimensions of 97 x 57 x 28 mm (3.81 x 2.24 x 1.1″) and weighs 182 g (0.40 lb / 6.42 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
GoPro Hero9 Black is 24g lighter than the Canon SX620 HS but we don't think this will make a significant difference.
Weather Sealing
With its weather-sealed body, we believe that the Hero9 Black has a big advantage over the SX620 HS which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Canon SX620 HS's 3.00" 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.
