Pick your grass type and lawn goal. We’ll suggest a mowing height range and quick tips. Remember the rule of thirds: never remove more than 1/3 of the blade at a time.

Recommended mowing height

Choose your grass and goal, then hit Calculate.

1/3 rule: If your current height is above this range, lower the deck gradually over several mows.

Why height matters

Cutting a little higher grows deeper roots, shades soil to retain moisture, and crowds out weeds. Lower “show” cuts can look crisp, but they require sharper blades, tighter intervals, and better nutrition.

  • Hot/dry weather: raise the deck 0.25–0.5" to reduce stress.
  • Shade: raise 0.25–0.5" and avoid removing more than 25% in a single mow.
  • High traffic: stay mid-to-high in range and rotate patterns weekly.
