Golden Rectangle or Golden Ratio are artistic terms for an "ideal" proportions of a rectangle. In mathematics it is demonstrated by the ratios of 2 consequent numbers in the series (0),1,1,2,3,5,8 ... 1134903170, 1836311903, 2971215073 ... where the next number is calculated by addition of the 2 numbers preceding it. As the numbers get bigger, the ratio gets more precise and closer to
1.618033989 which is half of 1+ √5
Much more and more precise information can be found in wikipedias or by searching the web. The only ambition of this page is to provide a quick, practical implementation of the phenomenon in web design. In order to avoid ambiguity, here is the description of what this page does:
It asks you to enter the two measurements of a rectangle
It labels the longer side width and the shorter side height
It allows the input in inches, centimeters, or pixels and converts the input to the remaining two units, using
1 inch = 2.54 cm = 72 px
It calculates the ideal length of the other side of the rectangle for both of the desired measures
