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 Sony TX20 and Sony W730 side-by-side from the front, back and top in their relative dimensions. Sony TX20 has external dimensions of 96 x 56 x 18 mm (3.78 x 2.2 x 0.71″) and weighs 133 g (0.29 lb / 4.69 oz) (including batteries). Sony W730 has external dimensions of 93 x 52 x 22 mm (3.66 x 2.05 x 0.87″) and weighs 122 g (0.27 lb / 4.30 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W730 is 11g lighter than the Sony TX20 but we don't think this will make a significant difference.
Weather Sealing
With its weather-sealed body, we believe that the TX20 has a big advantage over the W730 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony TX20's 3.00" LCD screen is slightly larger than Sony W730's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
