The smallest display diagonal of high megapixel cameras that are a comparable age to this digital camera is 2.7" and the largest is 3.2". With a display diagonal of only 2.7 inches, the Coolpix A100 has one of the smaller display diagonals amongst high megapixel cameras of this age.
We think you might also be interested in some of the alternative 2.7" screen digital cameras currently available including the Canon IXUS 175 (£89.99) which has better reviews.
If this camera display diagonal is too small for you then you might want to consider the Sony Alpha A7R (3" and higher rated), or the Canon SL1 (£840.67) (3" and higher rated).
