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 Leica X Vario and Canon SD940 IS side-by-side from the front, back and top in their relative dimensions. Leica X Vario has external dimensions of 133 x 73 x 95 mm (5.24 x 2.87 x 3.74″) and weighs 680 g (1.50 lb / 23.99 oz) (including batteries). Canon SD940 IS has external dimensions of 89 x 55 x 20 mm (3.5 x 2.17 x 0.79″) and weighs 120 g (0.26 lb / 4.23 oz) (including batteries).
Below you can see the front-view size comparison of the Leica X Vario and the Canon SD940 IS. Canon SD940 IS is clearly the smaller of the two cameras. Its body is 44mm narrower, 18mm shorter and 75mm thinner than Leica X Vario.
Here is the back view size comparison of the Leica X Vario and Canon SD940 IS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SD940 IS is significantly lighter (560g ) than the Leica X Vario which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Leica X Vario nor Canon PowerShot SD940 IS / Digital IXUS 120 IS 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
Leica X Vario's 3.00" LCD screen is slightly larger than Canon SD940 IS's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
