Brief History: Where the Acre Comes From
The acre originated from the Old English word aecer, meaning field. It traditionally referred to the amount of land a farmer could plow in one day with a yoke of oxen. This informal unit was eventually standardized to 43,560 square feet in the United States.
Understanding this helps frame how land was—and still is—used and valued.
Why Acreage Still Matters in Home Sales
For both buyers and home sellers, acreage often determines:
Market Value: Larger plots can increase price per square foot.
Development Potential: Room for expansion, subdivision, or additional structures.
Zoning Regulations: Lot size impacts what you can build or modify.
Curb Appeal & Buyer Intent: Some buyers specifically filter for homes with “1+ acres” in search.
