A quarter acre square is 104 feet a side, so about 417 feet all round, or 260 feet fencing three sides.

Post spacing compared
Closer posts mean a stiffer fence and a bigger post and concrete bill. Same run, three spacings.
| Post spacing | Posts needed | 50 lb concrete bags, whole job |

What else matters here
A quarter acre is 10,890 square feet. Perfectly square, that is 104 feet a side and 417 feet of perimeter. This page assumes the common real case instead: three sides fenced, with the house and driveway closing the fourth, which is about 260 feet.
Lot shape moves this number more than lot size does. A long narrow quarter acre can need half again as much fence as a square one for exactly the same land, so measure your own perimeter rather than trusting the acreage.
Before ordering, check the deed and the HOA. Setback rules, maximum heights, which side the finished face must point, and whether a fence is allowed forward of the house line are all things that get discovered after the posts are in far too often.
What this calculator assumes
- Sections are the length divided by the spacing, and posts are sections plus one. Corners and gates each add a post on top of that.
- Concrete per hole is the hole volume less the post, figured at a 4x4. Two 50 lb bags per hole is the common shortcut and it is close.
- Set posts a third of their length in the ground in frost country, and check your local frost depth before you dig.
Questions people ask
How many feet of fence for a quarter acre?
About 417 feet to enclose a square quarter acre completely, or around 260 feet for the common three sided layout. Lot shape changes this substantially.
How much does fencing a quarter acre cost?
Material is what this calculator gives you. Installed cost depends heavily on local labor and on whether the ground is diggable, which varies more than the lumber price does.
Do I need a permit to build a fence?
Often yes, especially over four or six feet or near a street. Check the building department and, separately, the HOA, because they impose different rules.
