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 Panasonic SZ3 and Sony W550 side-by-side from the front, back and top in their relative dimensions. 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). Sony W550 has external dimensions of 94 x 56 x 19 mm (3.7 x 2.2 x 0.75″) and weighs 110 g (0.24 lb / 3.88 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W550 is 16g lighter than the Panasonic SZ3 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-SZ3 nor Sony Cyber-shot DSC-W550 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Sony W550's 3.00" LCD screen is slightly larger than Panasonic SZ3's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
