Understanding Fence Calculations
Calculating the materials for a fence ensures you purchase the right quantity of posts, rails, and pickets, minimizing waste and costs. This calculator considers fence length, height, post spacing, picket spacing, and waste factor.
Posts are typically spaced 6-8 feet apart, and pickets are spaced 1-4 inches apart depending on the design. The waste factor accounts for cutting errors or damaged materials.
Fence Materials Comparison
| Fence Length | Posts (8 ft spacing) | Pickets (4 in width, 2 in spacing) | Typical Use |
|---|---|---|---|
| 50 ft | 7-8 | 150-165 | Small backyard |
| 100 ft | 13-15 | 300-330 | Medium property line |
| 200 ft | 25-28 | 600-660 | Large perimeter |
How to Use the Fence Calculator
- Measure the total fence length in feet.
- Enter the fence height in feet (affects rail length).
- Specify post spacing in feet (typically 6-8 ft).
- Enter picket width and spacing in inches (e.g., 4 in wide, 2 in spacing).
- Input a waste factor (typically 5-10%) and click "Calculate Fence Materials".

Frequently Asked Questions
Does fence height affect material calculations?
Yes, height affects rail length and may require additional posts for stability. Check local regulations for height limits.
Why include a waste factor?
A 5-10% waste factor accounts for cutting errors, damaged materials, or adjustments during installation.
