Chain Link Fence Calculator

Fencing Engineering & ASTM F567 Installation Metrology

Proper chain link fence construction requires standard structural components:

• **

• Fabric Mesh Roll Sizing**:

Rolls (50 ft) = Total Fence Length in Feet50

• **

• Post Count Formula (Max 10 ft On-Center)**:

Total Sections = LengthSpacing , Total Posts = Total Sections + 1

Line Posts = (0, Total Posts - Terminal Posts)

• **

• Top Rail Quantity (21 ft standard pipe)**:

Top Rails = Length21

• **

• Concrete Footing Requirements (ASTM F567)**:

• Line Posts (1(5) / (8)" - 2" OD): 2 bags (50 lb) per post (Hole: 6" - 8" wide × 24" deep).

• Terminal / Corner Posts (2(3) / (8)" - 2(7) / (8)" OD): 3 bags (50 lb) per post (Hole: 10" - 12" wide × 36" deep).

• **

• Standard Project Benchmarks**:

• 50 ft Run (4 ft H): 1 Roll | 2 Line Posts | 4 Corner Posts | 3 Top Rails | 16 Concrete Bags

• 150 ft Run (6 ft H): 3 Rolls | 12 Line Posts | 4 Corner Posts | 8 Top Rails | 36 Concrete Bags

• 300 ft Run (6 ft H): 6 Rolls | 25 Line Posts | 6 Corner Posts | 15 Top Rails | 68 Concrete Bags

• 500 ft Run (8 ft H): 10 Rolls | 43 Line Posts | 8 Corner Posts | 24 Top Rails | 110 Concrete Bags

How to Use This Calculator

Enter your Total Fence Line Length (e.g. 150 in ft), Fence Height — choose from 4 ft (Standard Residential Front Yard), 5 ft (Pet & Pool Safety Enclosure), 6 ft (Standard Residential Privacy & Security), Number of End, Corner & Gate Posts (e.g. 4), Line Post Spacing (Max 10 ft) — choose from 8 ft On-Center (Heavy Duty / Wind Prone), 10 ft On-Center (ASTM F567 Standard), and Perimeter Project Benchmark — choose from Custom Fence Layout, 150 ft Backyard (6 ft Height, 4 Corners) → 3 Rolls / 12 Line Posts, 50 ft Dog Run / Pen (4 ft Height, 4 Corners) → 1 Roll / 2 Line Posts. Measure twice before entering dimensions — small measurement errors scale up significantly in material estimates.

The Formula

Hardware (Tension bands = (height - 1) per terminal post; Tie wires = length / 2 + linePosts * height)

Worked Example

A homeowner fencing a 150-foot backyard perimeter with a 6-foot fence calculates that 3 rolls of 50-foot fabric, 12 line posts, 4 corner posts, 8 top rails, and 36 bags of concrete are required for a complete ASTM-compliant installation.

Understanding Your Result

Fence posts are typically set 1/3 of total post length below grade (6-foot post requires 2-foot hole). Post spacing: 6–8 feet on center for wood, 6 feet for vinyl panels (most pre-made sections). Minimum post concrete depth: 24 inches in USDA Hardiness Zones 6 and above; 30 inches for Zones 4–

• Dig below the frost line to prevent heaving — check local frost depth requirements. Add 10% waste factor to linear footage for overlap and end posts.
