The radius of a atom is about 10^-9 meters, a proton is a million times smaller at 10-15 meters, but the Planck length is 10-35 meters a hundred billion billion smaller than a proton. Take the smallest speck of dust you can see without a microscope and enlarge it to the size of the observable universe, within that universe the Plank length would be the smallest thing you could see without a microscope.
