Fence Calculator
Calculate the number of posts, rails, and pickets needed for your fence.
Enter perimeter, height, and post spacing.
Fence Materials
Fence material calculations:
Posts = (Perimeter / Post Spacing) + 1
Sections = Posts - 1
Rails = Sections × Rails per Section
Pickets = Perimeter / (Picket Width + Gap)
Unit conversions:
1 foot = 0.3048 meters1 inch = 2.54 cm
Imperial tips:
- Standard post spacing: 6 or 8 feet
- Most fences use 2 or 3 horizontal rails per section
- Standard picket width: 3.5 inches with 1.75 inch gap
- Add 10% extra for waste and cuts
Metric tips:
- Standard post spacing: 1.8 m or 2.4 m
- Standard picket width: 90 mm with 45 mm gap
- Add 10% extra for waste and cuts
