Weight is frequently used in product information and the design process. However; the perceived weight is greatly influenced by individual subjectivity. Guessing the exact weight using only numerical information and visual estimation is not easy. Therefore; this study focused on the relationship between the perceived weight and actual weight; and verified the difference between the subjective and physical senses of weight. In other words; we aimed to explore the error range; and to reveal the characteristics of the subjective sense of weight. We performed two experiments. Experiment A is for the ‘subjective sense of weight due to the difference in weigh’ using models with differing weights but the same size; and Experiment B is for the ‘subjective sense of weight by size’ using models with differing sizes but the same weight. In the results; the average subjective weight of the 170 g model was 223 g for an error rate of approximately 31%. On the other hand; the average subjective weight of the 100 g model was 103 g. Therefore; the error between the subjective and physical weights was greatest at 100–170 g in Experiment A. In Experiment B; the average subjective weight of the 170 g model with a diameter of 75 mm was 298 g; which is 75% greater than the physical weight. The error for the 170 g model was smallest at -4% when the diameter was 120 mm. In other words; the error decreased with increasing model size in Experiment B.
