This is a basic guide to pixel resolutions for various popular camera sizes
although a file may be small, dependant on the situation the picture is going to be displayed in could still be a quality image eg: if viewed from a distance a lower 150ppi can be used
for a quality printed image that is to be viewed close up say 2ft or closer a 300ppi is recommended
Top quality prints are achieved with a good quality image in the largest file size possible and in focus, if these are all present almost any size picture can be printed from a 6″x 4″ to billboard size
