What Height Should You Mow Your Lawn? (Recommended Settings & Key Factors)
For most cool-season grasses like Kentucky bluegrass or fescue, the ideal mowing height is 2.5–3 inches. For warm-season grasses like Bermuda or St. Augustine, the recommended height is 1.5–2 inches. A crucial rule for all lawns is to never remove more than one-third of the grass blade's total height in a single mowing session to avoid stressing the plant.
