How big can I go with
this image?
You can go as big as you like, but the resolution (amount of
information) will determine how far back from the print you need to view it for
it to look as you expect. It is a difficult question to answer as the
subject of the image can also affect how large you can print it before it starts
to deteriorate in quality. For prints around A2 (16”x24”) or smaller,
anything between 150 and 300dpi is best. The higher the better. For larger
prints, 150dpi is recommended, but 72-80 dpi is usually more than adequate for
large backgrounds.
Cropping of
images Cropping will often improve the
subject matter, keep in mind this will reduce pixels in photo thus
reducing Ideal print size
