File Sizes

The best printed or infused images result from files that have around the same resolution as the printer–about 300 dpi (dots per inch or pixels per inch). Images from drawing programs or photos can be software-adjusted to a lower resolution fairly easily, but those with too few pixels will not be “fixable” for printing even with software adjustments; the printed image will look “pixelated.” Most phone and lower-end digital cameras will not produce files large enough for large prints.

The ideal file sizes for printing/infusing are calc’d like this: (Height in inches X 300) times (Width in inches X 300).

Examples for standard size prints are as follows:

5″ x 7″ (5 x 300) x (7 x 300) = 1500 x 2100 = 3, 150,000 pixels = 3.15 megapixels

8″ x 10″ (8 x 300) x (10 x 300) = 2400 x 3000 = 7,200,000 pixels = 7.2 megapixels

16″ x 20″ (16 x 300) x (20 x 300) = 4800 x 6000 = 28,800,000 pixels = 28.8 megapixels

24″ x 30″ (24 x 300) x (30 x 300) = 7200 x 9000 = 64,800,000 pixels = 64.8 megapixels
