Planning a fence project? One of the most important things to get right is the spacing between fence posts. Proper spacing ensures the fence is sturdy, looks clean, and fits your layout perfectly. This Fence Post Distance Calculator helps you calculate the space between each post, accounting for the total length of your fence and the thickness of the posts.
Fence Post Distance Formula
To calculate the spacing between posts, follow these steps:
✅ Step 1: Convert Fence Length to Inches
Since post thickness is in inches, we first convert fence length from feet to inches:
Formula:
Total Length (in)=Fence Length (ft)×12
✅ Step 2: Calculate Total Post Thickness
Total Post Thickness=Number of Posts×Post Thickness (in)
✅ Step 3: Subtract Post Thickness from Total Length
Remaining Length=Total Length (in)−Total Post Thickness
✅ Step 4: Calculate Spacing Between Posts
Post Spacing=Number of Posts−1Remaining Length
Example: Fence Post Distance Calculation
Let’s say you want to build a 50-foot long fence using 6 posts, each 3.5 inches thick. Here's how you calculate the post spacing:
Step 1: Convert 50 ft to inches
Total Length=50×12=600 in
Step 2: Total thickness of 6 posts
Total Post Thickness=6×3.5=21 in
Step 3: Subtract post thickness
Remaining Length=600−21=579 in
Step 4: Calculate spacing
Post Spacing=6−1579=5579=115.8 in
Final Answer:
Each post should be spaced approximately 115.8 inches apart.
