About this calculator
A quarter-acre lot (10,890 square feet) fenced on all sides assuming a square shape needs about 417 linear feet of perimeter fencing. This calculator defaults to that assumption, then computes post count and total material cost based on your fence style price per foot and post spacing — adjust the perimeter directly if your lot isn't square.
Worked example
Using the values the calculator loads with:
Inputs
- Fence perimeter: 417 ft
- Post spacing: 8 ft
- Fencing price per linear foot: 22 $
- Price per post: 18 $
Results
- Estimated total fence cost: $10,146
- Fence length: 417
- Posts needed: 54
- Fencing material cost: $9,174
What each field means
Inputs
- Fence perimeter (ft)
- The fence perimeter used in the calculation, measured in ft. Starts at 417 ft so you have a working example on load.
- Post spacing (ft)
- The post spacing used in the calculation, measured in ft. Starts at 8 ft so you have a working example on load. Accepted range: 4–12 ft.
- Fencing price per linear foot ($)
- The fencing price per linear foot used in the calculation, measured in $. Starts at 22 $ so you have a working example on load.
- Price per post ($)
- The price per post used in the calculation, measured in $. Starts at 18 $ so you have a working example on load.

FAQ
How many linear feet of fence for a quarter acre?
Assuming a square lot, about 417 linear feet — a quarter acre is 10,890 square feet, and the side length of a square with that area is roughly 104 feet, times 4 sides.
Does this account for gates?
No, add gate hardware and framing separately since gate cost varies widely by width and material; this tool covers straight-run fencing and posts only.
What if my quarter-acre lot is a rectangle, not a square?
Enter your actual perimeter directly in the first field — the 417 ft default only applies to a square lot; a long narrow rectangle of the same area has a longer perimeter.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
