Now lets take a look at some common size ratios of different types of media.

Media	Width	Height	Ratio
4in x 6in photo print (landscape)	6	4	1.5
3.5in x 5in photo print (landscape)	5	3.5	1.429
5in x 7in photo print (landscape)	7	5	1.4
8in x 10in photo print (landscape)	10	8	1.25
8.5in x 11in letter size paper (portrait)	8.5	11	0.773
Standard TV	4	3	1.333
Computer Monitor	4	3	1.33
HDTV Widescreen	16	9	1.778
Landscape image	1760	1168	1.507
Portrait image	1168	1760	0.664

Notice that media that is wider than tall has a width to height ratio larger than 1 (a landscape type image). Media that is taller than wide has a ratio less than one (a portrait type image). If the image width and heights were the same, the ratio would be 1 (a square image). These are just a few fundamentals to keep in mind as we continue.
