A feeler gauge includes multiple feeler blades and an optical sensor. Each of the multiple feeler blades rotates about an axis between a measuring position and a non-measuring position. Each of the multiple feeler blades includes a measurement portion configured to be inserted into a gap to be measured and a proximal end having an indication of thickness of the respective feeler blade thereon. The optical sensor optically determines one or more of the multiple feeler blades that are deployed in the measuring position from the respective indications of thickness of each of the one or more feeler blades.
