I get what your saying about 1/4 or 1/2 acre but truthfully most consumers don't know how big their property is. The wives all have a small yard and the husband has a large yard. The wife thinks its not that big because when her husband cut it, it only took him 45 minutes. The husband thinks its huge because it took him 45 minutes to cut it.
If you do fertilizing you will understand the fact that customers don't know what size their lawn is.
They will tell you they put down about a bag when they did it. Then they show you a bag that covers 15k and you measure the lawn at 6k.
Landscapers talk in acres customers talk in big or small.
Regardless the object is still to get the phone to ring.
