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 Canon ELPH 150 IS and Panasonic SZ8 side-by-side from the front, back and top in their relative dimensions. Canon ELPH 150 IS has external dimensions of 95 x 57 x 24 mm (3.74 x 2.24 x 0.94″) and weighs 142 g (0.31 lb / 5.01 oz) (including batteries). Panasonic SZ8 has external dimensions of 100 x 60 x 27 mm (3.94 x 2.36 x 1.06″) and weighs 159 g (0.35 lb / 5.61 oz) (including batteries).
Below you can see the front-view size comparison of the Canon ELPH 150 IS and the Panasonic SZ8. Canon ELPH 150 IS is clearly the smaller of the two cameras. Its body is 5mm narrower, 3mm shorter and 3mm thinner than Panasonic SZ8.
Here is the back view size comparison of the Canon ELPH 150 IS and Panasonic SZ8.
Now lets look at the top view comparison of Canon ELPH 150 IS and Panasonic SZ8.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 150 IS is 17g lighter than the Panasonic SZ8 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot ELPH 150 IS (IXUS 155) nor Panasonic Lumix DMC-SZ8 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 SZ8's 3.00" LCD screen is slightly larger than Canon ELPH 150 IS's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
