The so-called proton radius puzzle, the roughly 4% difference in the extracted values for the root-mean square charge radius of the proton from electron spectroscopy and scattering on one side, and muon spectroscopy on the other, remains unsolved for nine years now. Recent results from spectroscopy and scattering shed new light on the puzzle, but so far fall short of a satisfactory solution. In the talk, I will discuss the current state of the puzzle and describe upcoming experiments.
