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 LX100 and Leica C side-by-side from the front, back and top in their relative dimensions. Panasonic LX100 has external dimensions of 115 x 66 x 55 mm (4.53 x 2.6 x 2.17″) and weighs 393 g (0.87 lb / 13.86 oz) (including batteries). Leica C has external dimensions of 103 x 63 x 28 mm (4.06 x 2.48 x 1.1″) and weighs 195 g (0.43 lb / 6.88 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic LX100 and the Leica C. Leica C is clearly the smaller of the two cameras. Its body is 12mm narrower, 3mm shorter and 27mm thinner than Panasonic LX100.
Here is the back view size comparison of the Panasonic LX100 and Leica C.
Now lets look at the top view comparison of Panasonic LX100 and Leica C.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Leica C is significantly lighter (198g ) than the Panasonic LX100 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-LX100 nor Leica C (Typ112) 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 LX100 and Leica C's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
