    depends on how good you want the quality to be.... use a calculator and work it out.

    e.g. a 6x4 print at 300ppi needs maybe 2MP or so.

    Depends on how far away you will be looking at the prints form and your personal tolaerance for detail. For 4 and 5R you will need around 300DPI (do the maths yourself ) Geneerally for larger prints you wont be viewing them as close so about 200DPI is pretty decent already. This is what I personally feel

    Hi,

    For example 4R=4"x6", if you create your pic with 300dpi (dpi=dot/pixel per inch), then you need 4"x300 by 6"x300 = 1200x1800pixel.

    Regarding what dpi to use, it depends on how far you view your pic. For more details, read this thread.
