The length of your mowed lawn depends on a number of factors, including the type of grass you have, the amount of water you use, and whether you are mowing at night or during the day. For example, if your lawn is 3 feet tall, it should be 3 to 4 inches long. If your grass is 2 feet high, you should cut it down to 2 to 3 inches.
