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 ZS3 and Canon D20 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS3 has external dimensions of 103 x 60 x 33 mm (4.06 x 2.36 x 1.3″) and weighs 229 g (0.50 lb / 8.08 oz) (including batteries). Canon D20 has external dimensions of 112 x 71 x 28 mm (4.41 x 2.8 x 1.1″) and weighs 228 g (0.50 lb / 8.04 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic ZS3 and the Canon D20. Panasonic ZS3 is 9mm narrower and 11mm shorter than Canon D20 but it is also 5mm thicker.
Here is the back view size comparison of the Panasonic ZS3 and Canon D20.
Now lets look at the top view comparison of Panasonic ZS3 and Canon D20.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon D20 is 1g lighter than the Panasonic ZS3 but we don't think this will make a significant difference.
Weather Sealing
Thanks to the weather-sealed body of the D20, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the ZS3.
LCD Screen Size and Features
Panasonic ZS3 and Canon D20'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.
