In this study, it is aimed to calculate the target size from its infrared (IR) image. Target is decomposed from background and target size is calculated depending on its pixel number on the thermal image. By using horizontal and vertical angular field of view (FOV) of thermal camera and distance between thermal camera and target, target size is estimated. Comparing obtained results with real target size show that this model has a good accuracy. Model can be used for target size calculation on the infrared image
