    At 300DPI 4R is 1800x1200(3:2) not 1600x1200 (4:3)

    8R is in (5:4) aspect ratio. At a300DPI you will need it to be 3000x2400. Genereally 200dpi is enough laio 1600x2000 ..

    300 dot per inch (dpi) will give photo quality

    formula:

    1 inch = 300 dot to give photo quality
    so 8R is 8 inches x 10 inches which gives ( 8 x 300 ) dots x ( 10 x 300 ) dots
    = 2400 x 3000
    = 7.2 megapixel

    This formula is a great help!

    Mini labs based on 300ppi. If you resized to fit to the size, you must let the lab know not to re-size, otherwise lab printing will be "size-to".

    Cant you increase the dpi for the scanner? 72 is way too low

    Reverse the formula

    to have photo quality, you need to print in 300 dpi

    so just divide the resolution by 300
    = (5xxx X 3xxx ) / 300
    = 5xxxx/300 inches x 3xxx/300 inches
    e.g. 5000 x 3000 can print up to 16.667 inches x 10 inches photo quality (300 dpi)

    Of course you can print lower quality like 150 dpi and you can print bigger size.
