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 FP3 and Canon ELPH 340 HS side-by-side from the front, back and top in their relative dimensions. Panasonic FP3 has external dimensions of 99 x 59 x 19 mm (3.9 x 2.32 x 0.75″) and weighs 155 g (0.34 lb / 5.47 oz) (including batteries). Canon ELPH 340 HS has external dimensions of 100 x 58 x 22 mm (3.93 x 2.27 x 0.88″) and weighs 147 g (0.32 lb / 5.19 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic FP3 and the Canon ELPH 340 HS. Panasonic FP3 is 1mm narrower and 3mm thinner than Canon ELPH 340 HS but it is also 1mm taller.
Here is the back view size comparison of the Panasonic FP3 and Canon ELPH 340 HS.
Now lets look at the top view comparison of Panasonic FP3 and Canon ELPH 340 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 340 HS is 8g lighter than the Panasonic FP3 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-FP3 nor Canon PowerShot ELPH 340 HS (IXUS 265 HS) 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 FP3 and Canon ELPH 340 HS'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.
