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 ELPH 135 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 ELPH 135 has external dimensions of 95 x 54 x 22 mm (3.74 x 2.13 x 0.87″) and weighs 127 g (0.28 lb / 4.48 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 135 is 8g 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 ELPH 135 (IXUS 145) 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
Canon A2500's 3.00" LCD screen is slightly larger than Canon ELPH 135's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
