Picket Calculation Formula:
From: | To: |
The Wood Fence Picket Calculator determines the number of pickets needed for a fence based on the fence length, post widths, picket width, and desired gap between pickets. It helps in planning and material estimation for fence construction.
The calculator uses the following equation:
Where:
Explanation: The formula converts fence length to inches, subtracts space taken by posts, then divides by the space each picket occupies (including its width and gap).
Details: Proper calculation ensures you purchase the correct number of pickets, prevents material waste, and helps achieve uniform spacing for an aesthetically pleasing fence.
Tips: Measure your fence length carefully. Include all post widths (standard 4x4 posts are 3.5" wide). Typical picket widths range from 3.5" to 5.5". Common gaps are 1"-3" for privacy fences.
Q1: Should I round up or down the result?
A: Always round up to ensure you have enough pickets. You may need to slightly adjust gaps for an exact fit.
Q2: How do I account for corner posts?
A: Include all posts in your "Post Widths" calculation - both line posts and corner posts.
Q3: What's a typical gap between pickets?
A: For privacy fences, 1-2 inches. For semi-private, 2-3 inches. For picket fences, gaps may be larger.
Q4: How do I calculate post widths?
A: Multiply the width of one post by the number of posts. For example: 10 posts × 3.5" = 35" total.
Q5: Should I add extra pickets for mistakes?
A: It's recommended to add 5-10% extra to account for cutting errors or damaged pickets.
