A radiographic image capturing system includes the following. A capturing stand includes a holder which can hold a plurality of radiographic image capturing devices. A radiation irradiator is able to apply radiation to the radiographic image capturing devices loaded in the holder at once. A console carries out image processing on image data acquired by the radiographic image capturing devices. The console carries out the image processing through application of a parameter applied to image data acquired by a radiographic image capturing device assigned with a predetermined number to image data acquired by the other radiographic image capturing devices. The predetermined number is a number from multiple numbers assigned to the radiographic image capturing devices loaded in the holder in an ascending order from a head to toe of a patient.
