Fence Calculator
Estimate fence sections, posts, rails, gate openings, and concrete bags.
What this calculator does
Gate width is removed before full sections and their boundary posts are counted.
Fence materials
Gate openings are removed before sections are counted. A continuous run uses one more boundary post than sections.

Gate openings are removed before sections and boundaries are counted.
The arithmetic uses the exact values shown above. Verify field measurements, product pack sizes, layout constraints, and local requirements before ordering or building.
How to interpret the result
Gate width is removed before full sections and their boundary posts are counted.
How the result is calculated
Sections = ceil((length - gate width) ÷ panel width).
Worked example
A 100 ft run with one 4 ft gate and 8 ft panels uses 12 sections and 14 posts.
Practical guidance
- Measure the project at least twice before ordering.
- Use actual product dimensions and package coverage.
- Keep a saved or printed copy of the inputs used for the estimate.
Assumptions and limitations
Corners, disconnected runs, slopes, wind loading, hardware, and local post requirements vary.
Methodology
Calculations use standard geometry and normalized units. Countable products are rounded up where partial products cannot normally be purchased.

Frequently asked questions
Are results rounded for purchasing?
Countable materials and packages are rounded up. Measured area, length, volume, and cost remain decimal values where appropriate.
Is this a final construction specification?
No. It is a transparent planning estimate. Verify product instructions, site conditions, plans, and local requirements.
