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 SX40 HS and Canon SX50 HS side-by-side from the front, back and top in their relative dimensions. Canon SX40 HS has external dimensions of 123 x 92 x 108 mm (4.84 x 3.62 x 4.25″) and weighs 600 g (1.32 lb / 21.16 oz) (including batteries). Canon SX50 HS has external dimensions of 123 x 87 x 106 mm (4.84 x 3.43 x 4.17″) and weighs 595 g (1.31 lb / 20.99 oz) (including batteries).

Here is the back view size comparison of Canon SX40 HS and Canon SX50 HS.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon SX50 HS is 5g lighter than the Canon SX40 HS but we don't think this will make a significant difference.
Unfortunately neither Canon PowerShot SX40 HS nor Canon PowerShot SX50 HS provides any type of weather sealing in their body, 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 Bridge Cameras with Weather Sealing
