Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Canon A2500 and Canon A2300 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).

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon A2300 is 10g lighter than the Canon A2500 but we don't think this will make a significant difference.
Unfortunately neither Canon PowerShot A2500 nor Canon PowerShot A2300 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
