Canon A3400 IS has external dimensions of 94 x 56 x 21 mm (3.7 x 2.2 x 0.83″) 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.
Canon A3400 IS is 10g lighter than the Panasonic SZ5 but we don't think this will make a significant difference.

Unfortunately neither the Canon PowerShot A3400 IS nor Panasonic Lumix DMC-SZ5 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Canon A3400 IS and Panasonic SZ5's LCD screens have the same diagonal size of 3.00 inches.
