The average display diagonal of camcorders of a similar age and type to this video camera is 2.9". At 3 inches, the Vixia HF R40 has a quite large display diagonal compared to most of the other small total megapixels video cameras that have been available for around the same time as this camcorder.
We think you might also be interested in some of the alternative 3" screen size video cameras currently available including because of their better review scores, the Legria HF M52, or the Legria HF M56 both from Canon.
If you would prefer a larger display diagonal then you might want to consider the Canon XF105 (£1,999) (3.5") which is also higher rated.
