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 Sony RX100 VI and Panasonic ZS300 side-by-side from the front, back and top in their relative dimensions. Sony RX100 VI has external dimensions of 102 x 58 x 43 mm (4.02 x 2.28 x 1.69″) and weighs 301 g (0.66 lb / 10.62 oz) (including batteries). Panasonic ZS300 has external dimensions of 111 x 66 x 45 mm (4.37 x 2.6 x 1.77″) and weighs 337 g (0.74 lb / 11.89 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony RX100 VI is 36g lighter than the Panasonic ZS300 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-RX100 VI nor Panasonic Lumix DC-ZS300 (Lumix DC-TZ300) 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
Sony RX100 VI and Panasonic ZS300's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Sony RX100 VI features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Panasonic ZS300 has a fixed type screen which provides less flexibility in shooting positions compared to RX100 VI.
