In order to determine the largest possible size an image can be printed, there are a few factors to consider:

The Size of the image (pixels) – Higher number of pixels means larger images for a given DPI.
The Quality of the image – A clean crisp photo can be successfully enlarged by 2X to 4X in software, prior to printing.
The Viewing Distance – Images viewed up close should be printed at 200-300 DPI (dots per inch); however, at a viewing distance of 4ft. or more, 150 DPI or so will produce a very good result.

The DPI of a printed image is determined by taking the image’s total pixels (length or width) and dividing by the number of inches desired of the print. It’s common to work the relationship in reverse to get the approximate size that an image can be printed.

Example: For a 16 mpix camera that produces an image file of 4928 x 3264 pixels:
At 300 dpi this produces a print 4928  ÷ 300 = 16.42 inches wide.
At 150 dpi this produces a print 4928  ÷ 150 = 32.85 inches wide.
At 100 dpi this produces a print 4928  ÷ 100 = 49.27 inches wide.

The above numbers can normally be increased if the quality of the image permits enlargement of 3X to 5X in software.

Example: For Wall Mural image Yosemite – Half Dome is 30,843 x 13,512 px.

With no enlargement and 150 DPI, an excellent print of 17 ft. x 7.5 ft. can be produced.
Since the quality of this image is sufficient to more than triple its size in software, a print of at least 51 ft. x 22 ft. is attainable.

In summary, Light Panels and Wall Murals have excellent detail printed at 150 DPI because the viewing distance is normally 3ft. or more. It is safe to assume that any wall mural image on our site can be enlarged 3 to 5 times its native size at 150dpi.
