About This Calculator

Our fence picket spacing calculator determines the perfect gap between pickets for even, professional-looking results. Uneven picket spacing is one of the most visible signs of amateur fence work, and it's easily avoided with proper planning before you start.

The calculator computes how many pickets fit in your fence section and the exact gap needed for perfect symmetry. You can specify a desired gap or let the calculator determine optimal spacing based on your section length and picket width.

This tool is perfect for DIY fence builders, handymen replacing fence sections, and anyone asking "how do I space pickets evenly?" or "how many pickets for an 8-foot section?" Taking a few minutes to calculate ensures your fence looks great for years to come.

How to Use This Calculator

Follow these steps to calculate picket spacing:

  1. Measure your fence section length in inches (post to post)
  2. Enter your picket width (standard is 3.5" or 5.5")
  3. Enter desired gap (or leave as 0 for automatic calculation)
  4. Review the number of pickets and exact gap spacing
  5. Mark your first and last picket positions, then divide gaps evenly
Frequently Asked Questions

What is the standard gap between fence pickets?

Standard picket gaps range from 2-3 inches for decorative fences to 0 (touching) for privacy fences. Dog-ear fences often use gaps matching the picket width (3.5") for a balanced look. Tighter gaps provide more privacy; wider gaps improve airflow and reduce wind load.

How many pickets do I need for a 6-foot section?

For a 72" section with 3.5" pickets and 3" gaps: 72 / (3.5 + 3) = 11 pickets. For privacy fencing with no gap: 72 / 3.5 = 21 pickets. Exact count varies by your chosen gap - use the calculator for precise numbers.

How do I install pickets with even spacing?

Make a spacer block matching your calculated gap. Install the first picket plumb, then use the spacer to position each subsequent picket. Check plumb every 4-5 pickets. Alternatively, mark all picket positions on the rails before nailing.

Should pickets touch the ground?

No, pickets should be 2-4 inches above ground to prevent rot and allow trimming beneath. Use a 2x4 or string line as a guide during installation. For slopes, "rack" the fence (angle pickets to follow grade) or "step" it (horizontal sections at different heights).

What if my spacing doesn't come out even?

Adjust the gap slightly - even 1/16" change per gap is invisible but adds up. You can also adjust post spacing slightly before setting posts. For existing posts with awkward spacing, rip the last picket narrower rather than having an odd gap.

How do I handle fence gates and corners?

Calculate gate sections separately using the gate opening width minus hinge and latch clearance. For corners, you can miter pickets for a clean look or simply butt them with the gap. On slopes, gate sections should be level even if fence sections rack.
