2.25MB File

"2.25MB" is a digital image file that has an average file size of about 2.25 megabytes when it is uncompressed*. This file usually averages about 1024 x 768 pixels. (This is equivalent to an XGA computer monitor resolution, and is the most common file size used for electronic presentations, i.e. PowerPoint.)

File size	Image size	Resolution in ppi**	Use or Application
1024 x 768 pixels	=14.3" x 10.7"	when reproduced @ 72 ppi	WEB or AV resolution use
1024 x 768 pixels	= 6.8" x 5.1"	when reproduced @ 150 ppi	minimum INKJET or LASER printer resolution for smooth or non-"jaggy" results.
1024 x 768 pixels	= 6.0" x 4.5"	when reproduced @ 170 ppi	average NEWSPAPER or NEWSLETTER resolution (85 line screen)
1024 x 768 pixels	= 4.6" x 3.4"	when reproduced @ 225 ppi	minimum resolution for acceptable 4-color MAGAZINE or BROCHURE printing (133 to 150 line screen)
1024 x 768 pixels	= 3.4" x 2.6"	when reproduced @ 300 ppi	average resolution for quality 4-color MAGAZINE or BROCHURE printing. (150 to 175 line screen); or for best INKJET or LASER printing.

*Our images are delivered as quality compressed JPEG images that average about one-sixth their uncompressed file size, in order to allow for faster Internet delivery. Once received and decompressed, these files should be saved as TIFF files (for final use), and the original JPEG file archived for back-up.

**PPI stands for "pixels per inch". This term is often used synonymously with DPI or "dots per inch". However, "dpi" more correctly refers to the output dots that are used in printing. The Picture Elements ("Pixels") of RGB and greyscale digital imagery are converted to the dots used in most mechanical printing processes. Inkjet prints are reproduced with black, cyan, magenta and yellow dots, having various output resolutions (i.e. "600 x 600 dpi or "720 x 1440"). The larger halftone "dots" in laser printers, newspapers, newsletters, and 4-color offset printing are arranged in rows, and described as "line screen" resolution.
