Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Canon SX20 IS and Leica D-Lux 6 side-by-side from the front, back and top in their relative dimensions. Canon SX20 IS has external dimensions of 128 x 88 x 87 mm (5.04 x 3.46 x 3.43″) and weighs 600 g (1.32 lb / 21.16 oz) (including batteries). Leica D-Lux 6 has external dimensions of 111 x 68 x 46 mm (4.37 x 2.68 x 1.81″) and weighs 298 g (0.66 lb / 10.51 oz) (including batteries).
Below you can see the front view size comparison of Canon SX20 IS and Leica D-Lux 6. Leica D-Lux 6 is clearly the smaller of the two cameras. Its body is 17mm narrower, 20mm shorter and 41mm thinner than Canon SX20 IS.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Leica D-Lux 6 is significantly lighter (302g ) than the Canon SX20 IS which may become a big advantage especially on long walking trips.
Unfortunately neither Canon PowerShot SX20 IS nor Leica D-Lux 6 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Leica D-Lux 6's 3 LCD screen is slightly larger than Canon SX20 IS's 2.5" screen.
On the other hand, Canon SX20 IS sports a Fully Articulated screen
which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. On the other hand, Leica D-Lux 6 has a fixed type screen which provides almost no flexibility in shooting positions compared to SX20 IS.
