### How many feet in a Square Acre of Land?

A question that I often receive from new land surveyors is  How many feet is a square acre?

I am not quite sure why this stumps so many, but this is basically what I tell them with they ask.

square enclosing one acre is approximately 69.57 yards, or 208 feet 9 inches (63.61 metres) on a side. As a unit of measure, an acre has no prescribed shape; any area of 43,560 square feet is an acre.

Keep in mind the following:

Because an acre is a measure of area, not length, it is defined in square feet. Anacre can be of any shape-a rectangle, a triangle, a circle, or even a star-so long as its area is exactly 43,560 square feet. The most standard shape for an acre is one furlong by one chain, or 660 feet by 66 feet.

• Also, when talking about a Section of land, people will say "oh, that's 640 acres !" Not true. Ideally, theoretically is would be. But in reality, as laid out, it usually is not.
Buying one Section of land is like buying a Pound of nails.  Scientifically we can determine how many nails of a certain type make one Pound. But in reality the clerk weighs out One Pound of nails. There may be more or less by actual count. But counting them out is not practical. Section of land, Pound of nails. I once got into an argument with a Realtor about the North most row (and East most column) of Sections in a Township (especially)  not necessarily having EXACTLY 640 acres. And he was teaching the real estate class.

Nice post!
