I had a lawn in my front yard. Emphasis on “had”. I took it out after realizing how much water it needed.
Grab a tape measure and measure your lawn. Start at one end and lay the tap measure down, if you run out of tape measure, stop in that spot, coil up the tape and start measuring again from that spot. Then add all the lengths together for that run. Then measure perpendicular from the run you just had so you end with a final Length x Width. Multiply the two numbers together to get your lawn area.
