Size and Weight
The length and width of a rice grain are important features that determine the class of the rice. There are three main classes of rice, based on grain length: short, medium and long. In terms of width, arborio grains are generally the widest, followed by short, medium and long grain varieties.
The ratio of length to width is used in international trade to describe
Length and width are measured on brown rice and grain weight is measured on paddy rice.
* Grain weight is measured by weighing 1000 paddy grains with a moisture content of 14%.
