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 A2500 and Canon A2400 IS side-by-side from the front, back and top in their relative dimensions. Canon A2500 has external dimensions of 98 x 56 x 20 mm (3.86 x 2.2 x 0.79″) and weighs 135 g (0.30 lb / 4.76 oz) (including batteries). Canon A2400 IS has external dimensions of 94 x 54 x 20 mm (3.7 x 2.13 x 0.79″) and weighs 126 g (0.28 lb / 4.44 oz) (including batteries).
Below you can see the front-view size comparison of the Canon A2500 and the Canon A2400 IS. Canon A2400 IS is 4mm narrower and 2mm shorter than Canon A2500 but they have the same thickness of 20mm.
Here is the back view size comparison of the Canon A2500 and Canon A2400 IS.
Now lets look at the top view comparison of Canon A2500 and Canon A2400 IS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon A2400 IS is 9g lighter than the Canon A2500 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot A2500 nor Canon PowerShot A2400 IS provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Canon A2500's 3.00" LCD screen is slightly larger than Canon A2400 IS's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
