1. What is Board On Board Fence?

A board on board fence is a type of privacy fence where vertical boards are installed on both sides of the horizontal rails with overlapping edges, creating a solid barrier with no gaps between the boards.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Fence Length — Total length of the fence in feet
• Picket Width — Width of each picket in inches
• Overlap — Amount of overlap between pickets in inches

Explanation: The formula converts feet to inches (×12), accounts for the effective width of each picket (width - overlap), and adds 1 for the starting picket.

3. Importance of Accurate Calculation

Details: Proper calculation ensures you purchase the correct number of pickets, avoiding waste or shortage during installation. It also helps estimate material costs accurately.

4. Using the Calculator

Tips:

• Measure your fence line accurately in feet
• Know your picket width (typically 3.5-5.5 inches)
• Determine desired overlap (usually 0.5-1.5 inches)
• Round up to whole numbers when purchasing materials

5. Frequently Asked Questions (FAQ)

Q1: What's the typical overlap for board on board fences?
A: Most installations use 0.5-1.5 inches of overlap, depending on desired privacy and aesthetic.

Q2: How do I account for gates in my calculation?
A: Subtract the gate width from your total fence length before calculating pickets.

Q3: What's the standard picket width?
A: Common widths are 3.5" (1x4 actual) or 5.5" (1x6 actual), but custom sizes are available.

Q4: Should I add extra pickets to my order?
A: It's recommended to add 5-10% extra for waste, cutting errors, and future repairs.

Q5: How does this differ from shadow box fence calculation?
A: Shadow box fences typically have less overlap and alternate board placement on each side of the rails.
