A pressure sensing system and a pressure sensing setting method are provided. The pressure sensing system includes a first pressure sensing sheet, a second pressure sensing sheet, and a processing device. The first flexible substrate of the first pressure sensing sheet has a first conductive pattern; the second flexible substrate of the second pressure sensing sheet has a second conductive pattern. The second pressure sensing sheet has the second conductive pattern stacked with the first conductive pattern of the first pressure sensing sheet. The processing device outputs electric signal to the first pressure sensing sheet; the second pressure sensing sheet obtains a pressure sensing signal, which is compared with a threshold value, determining if the first pressure sensing sheet and the second pressure sensing sheet are pressed by an external force, thereby preventing erroneous signal and improving measurement accuracy.
