Paddy (orzya sativa L.) is the worlds most important food crop and is primary food source for over one third of the worlds population. The objectives were to analyse the shape of raw rice varieties in terms of roundness roundness ratio and sphericity. Jirafull, sarna, komal, sonam, gurmarima, goraknath, ir36, mansuri, karhani, rambhog, which are the very common varieties of rice found, the shape of the raw rice was measured using the projection method. Among the selected varieties roundness value of raw rice varies from 0.45-0.71 for raw rice roundness is highest for jirafull and the lower for ir36. The value of roundness ratio of raw rice varies from 0.034-0.557 for raw rice sphericity is highest for jirafull and lowest for ir36. The value of sphericity of raw rice varies from 0.31-0.48. This study can be useful for designing of various types of processing and handling device and equipment for rice.
