Fence Posts Calculation:
The Wood Fence Calculator helps estimate the materials needed to build a wooden fence based on fence length, post spacing, and number of gates. It calculates the number of posts, rails, pickets, and concrete bags required.
The calculator uses these formulas:
Where:
Explanation: The calculations account for standard fence building practices with 3 rails between posts and pickets spaced about 0.5 inches apart.
Details: Accurate material estimation helps prevent project delays, reduces waste, and ensures you purchase the correct quantities of materials.
Tips:
Q1: What's the standard height for a privacy fence?
A: Most privacy fences are 6 feet tall, but local regulations may vary.
Q2: How deep should fence posts be set?
A: Generally 1/3 of the post length should be underground (e.g., 2 feet for a 6-foot fence).
Q3: What type of wood is best for fencing?
A: Cedar and pressure-treated pine are popular choices for their durability and resistance to rot.
Q4: How much concrete is needed per post?
A: Typically two 50lb bags of fast-setting concrete per post for a 4×4 post in a 10" diameter hole.
Q5: Should I space pickets with gaps?
A: Small gaps (about 0.5 inches) allow for wood expansion and better wind resistance.
