Abstract: An electronic device and method for measuring biometric information are provided. The electronic device includes at least one light emitter; light receiver; and a processor. The processor is configured to emit light outside of the electronic device through the at least one light emitter, obtain, through the light receiver, light reflected by an external object among the emitted light, obtain a signal generated based on at least a portion of the reflected light and corresponding to the external object, output guide information related to a location of the external object when the signal satisfies a first designated condition, and obtain biometric information about the external object when the signal satisfies a second designated condition. When a finger of a user finger of the electronic device is not accurately located at a bio sensor, by guiding an accurate grip location, biometric information about the user can be accurately measured.
