Cameras of this age and spec have display diagonals of between 2" and 4.8", and the average display diagonal is 2.9". When compared to other cameras of this spec and age that we have assessed, the Canon ELPH 320 HS's display diagonal of 3.2 inches is one of the largest.
We compared all the other 3.2" screen digital cameras to this camera and we think the Canon 240 HS which has better reviews is also worth considering.
If this Canon camera display diagonal is too small for you then you might want to consider the Samsung SAMSUNG MV900F (3.3"), or the Leica T (£359) (3.7") which also has a higher rating.
