Size and weight are big decision factors when you are trying to find the ideal camera for your needs.

Panasonic SZ1 has external dimensions of 99 x 59 x 21 mm (3.9 x 2.32 x 0.83″) and weighs 131 g (0.29 lb / 4.62 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic SZ1 is 4g lighter than the Canon Elph 115 IS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-SZ1 nor Canon Elph 115 IS (IXUS 132 HS) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Panasonic SZ1 and Canon Elph 115 IS's LCD screens have the same diagonal size of 3.00 inches.
