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 ELPH 510 HS and Canon SX230 HS side-by-side from the front, back and top in their relative dimensions. Canon ELPH 510 HS has external dimensions of 99 x 59 x 22 mm (3.9 x 2.32 x 0.87″) and weighs 206 g (0.45 lb / 7.27 oz) (including batteries). Canon SX230 HS has external dimensions of 106 x 62 x 33 mm (4.17 x 2.44 x 1.3″) and weighs 223 g (0.49 lb / 7.87 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 510 HS is 17g lighter than the Canon SX230 HS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon ELPH 510 HS (IXUS 1100 HS) nor Canon PowerShot SX230 HS 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 ELPH 510 HS's 3.20" LCD screen is slightly larger than Canon SX230 HS's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
