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 IV and Panasonic LX10 side-by-side from the front, back and top in their relative dimensions. Sony RX100 IV has external dimensions of 102 x 58 x 41 mm (4.02 x 2.28 x 1.61″) and weighs 298 g (0.66 lb / 10.51 oz) (including batteries). Panasonic LX10 has external dimensions of 106 x 60 x 42 mm (4.17 x 2.36 x 1.65″) and weighs 310 g (0.68 lb / 10.93 oz) (including batteries).
Below you can see the front-view size comparison of the Sony RX100 IV and the Panasonic LX10. Sony RX100 IV is clearly the smaller of the two cameras. Its body is 4mm narrower, 2mm shorter and 1mm thinner than Panasonic LX10.
Now lets look at the top view comparison of Sony RX100 IV and Panasonic LX10.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony RX100 IV is 12g lighter than the Panasonic LX10 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-RX100 IV nor Panasonic Lumix DMC-LX10 (Lumix DMC-LX15) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Sony RX100 IV and Panasonic LX10's LCD screens have the same diagonal size of 3.00 inches.

Tilting screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels.
