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 Canon ELPH 340 HS 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). Canon ELPH 340 HS has external dimensions of 100 x 58 x 22 mm (3.93 x 2.27 x 0.88″) and weighs 147 g (0.32 lb / 5.19 oz) (including batteries).
Below you can see the front-view size comparison of the Sony TX20 and the Canon ELPH 340 HS. Sony TX20 is clearly the smaller of the two cameras. Its body is 4mm narrower, 2mm shorter and 4mm thinner than Canon ELPH 340 HS.
Here is the back view size comparison of the Sony TX20 and Canon ELPH 340 HS.
Now lets look at the top view comparison of Sony TX20 and Canon ELPH 340 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony TX20 is 14g lighter than the Canon ELPH 340 HS 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 ELPH 340 HS which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony TX20 and Canon ELPH 340 HS's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
