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 Nikon S3700 and Sony TX20 side-by-side from the front, back and top in their relative dimensions. Nikon S3700 has external dimensions of 96 x 58 x 20 mm (3.78 x 2.28 x 0.79″) and weighs 118 g (0.26 lb / 4.16 oz) (including batteries). 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).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S3700 is 15g lighter than the Sony TX20 but we don't think this will make a significant difference.
Weather Sealing
Thanks to the weather-sealed body of the TX20, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the S3700.
LCD Screen Size and Features
Sony TX20's 3.00" LCD screen is slightly larger than Nikon S3700's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
