Length To Width Ratio

Round Brilliant Cut - Length-To-Width Ratio:
Length-to-width ratio is only important in the selection of a fancy cut diamonds. It is not considered in the selection of a round diamond because its length and width measurements are always very near a 1 to 1 ratio. When calculating length-to-width ratio the measurements are always calculated to the one-hundredth of a millimeter. 

Length-To-Width Ratio - Fancy Shape Diamonds 
The length-to-width ratio is calculated by dividing the length of the diamond by the width. For example, an oval diamonds length equals 8.00 millimeters, and its width measures 6.00 millimeters; 8.00 divided by 6.00 equals a length-to-width ratio of 1.5 to 1. 

To learn the accepted standard for the ideal length to width ratio for a specific diamond shape, return to the page Choosing Ideal Diamond Cut and select the desired diamond shape and refer to the chart under length to width ratio.
