The "1/3 rule for grass" is a fundamental lawn care guideline stating you should never remove more than one-third of a grass blade's total height in a single mowing session to prevent stressing the plant, which promotes stronger roots, better water retention, and discourages weeds. If your grass gets too tall (e.g., 6 inches), instead of cutting it all down at once, you would cut off only 2 inches, leaving 4 inches, and then mow again in a few days to reach the desired height.
