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 ZS100 and Canon SX160 IS side-by-side from the front, back and top in their relative dimensions. Panasonic ZS100 has external dimensions of 111 x 65 x 44 mm (4.37 x 2.56 x 1.73″) and weighs 312 g (0.69 lb / 11.01 oz) (including batteries). Canon SX160 IS has external dimensions of 111 x 73 x 44 mm (4.37 x 2.87 x 1.73″) and weighs 291 g (0.64 lb / 10.26 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic ZS100 and the Canon SX160 IS.
Here is the back view size comparison of the Panasonic ZS100 and Canon SX160 IS.
Now lets look at the top view comparison of Panasonic ZS100 and Canon SX160 IS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX160 IS is 21g lighter than the Panasonic ZS100 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS100 (Lumix DMC-TZ100) nor Canon PowerShot SX160 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
Panasonic ZS100 and Canon SX160 IS'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.
