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 Nikon A100 and Panasonic ZS60 side-by-side from the front, back and top in their relative dimensions. Nikon A100 has external dimensions of 95 x 59 x 20 mm (3.74 x 2.32 x 0.79″) and weighs 119 g (0.26 lb / 4.20 oz) (including batteries). Panasonic ZS60 has external dimensions of 112 x 64 x 38 mm (4.41 x 2.52 x 1.5″) and weighs 282 g (0.62 lb / 9.95 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon A100 and the Panasonic ZS60. Nikon A100 is clearly the smaller of the two cameras. Its body is 17mm narrower, 5mm shorter and 18mm thinner than Panasonic ZS60.
Here is the back view size comparison of the Nikon A100 and Panasonic ZS60.
Now lets look at the top view comparison of Nikon A100 and Panasonic ZS60.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon A100 is significantly lighter (163g ) than the Panasonic ZS60 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix A100 nor Panasonic Lumix DMC-ZS60 (Lumix DMC-TZ80) 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 ZS60's 3.00" LCD screen is slightly larger than Nikon A100's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
