To measure small things you need comparably short wavelengths.  If you make a photon with a wavelength so short it can measure the Planck length it will have so much mass-energy that it will fold spacetime around it and become a black you won't be able to use it to measure anything.

What is the argument for the claim that we cannot, in principle, measure any length smaller than Planck length? TIA, AG
