How to use this fence material calculator
A fence materials list depends on total run, allowable bay width, gates and board spacing. This calculator helps you estimate a straight fence line. Corners, slopes and gate placement can change the number of posts and rails in the final layout.
Step-by-step instructions
- Measure the complete fence line, including planned gates.
- Choose bay spacing, number of gates and gate widths.
- Adjust picket width, gap and rail count for your design.
Calculation formula
Important assumptions and limitations
Straight run with gates within the run. Gate placement, corners, terminal posts and nonuniform bay lengths can require more posts. Verify wind exposure and local building requirements.
For material orders, confirm package yields, stock sizes and installation instructions with the actual manufacturer or supplier. Your building department determines the applicable local code; a quantity estimator is not a structural design or permit approval.
Frequently asked questions
Will gate posts need to be larger?
Often yes. Actual gate hardware, load, wind and gate opening determine required post size and support.
Why is my post count approximate?
A total fence length cannot show where individual gates and corners are located. A dimensioned layout is needed for an exact post schedule.
