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 XS1 and Panasonic S3 side-by-side from the front, back and top in their relative dimensions. Panasonic XS1 has external dimensions of 94 x 54 x 14 mm (3.7 x 2.13 x 0.55″) and weighs 103 g (0.23 lb / 3.63 oz) (including batteries). Panasonic S3 has external dimensions of 99 x 59 x 21 mm (3.9 x 2.32 x 0.83″) and weighs 117 g (0.26 lb / 4.13 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic XS1 and the Panasonic S3. Panasonic XS1 is clearly the smaller of the two cameras. Its body is 5mm narrower, 5mm shorter and 7mm thinner than Panasonic S3.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic XS1 is 14g lighter than the Panasonic S3 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-XS1 nor Panasonic Lumix DMC-S3 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Panasonic XS1 and Panasonic S3's LCD screens have the same diagonal size of 2.70 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
