Panasonic SZ3 has external dimensions of 95 x 56 x 22 mm (3.74 x 2.2 x 0.87″) and weighs 126 g (0.28 lb / 4.44 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

LCD Screen Size and Features
Olympus TG-5's 3.00" LCD screen is slightly larger than Panasonic SZ3's 2.7" screen.
