Here Are Some Tips to Install a Picket Fence

1) Define the Purpose and Plan Your Layout

Start with the “why” before you start digging.

• outline a front yard boundary?
• protect a garden or landscaping?
• add curb appeal for resale?
• keep small pets in (or out)?

Once you know the purpose, plan the layout. Mark your fence line and decide where gates will go. In many neighborhoods, you’ll also need to confirm HOA requirements and local rules for fence height and placement.

Pro tip: Call 811 before you dig so utilities can be marked.

2) Confirm Local Rules and Property Lines

• your property line (avoid neighbor disputes)
• setback requirements (distance from sidewalks/roads)
• maximum allowed height in the front yard
• whether a permit is required

Even if a permit isn’t required, it’s worth checking city guidelines so you don’t have to redo work later.

3) Measure, Stake, and String-Line Everything

• Place stakes at corners and ends
• Run a taut string line between points
• Mark post locations evenly (common spacing is 6–8 feet depending on panel/rail design)

If your string line is straight, your fence will be straight.

4) Dig Proper Post Holes (Depth Matters)

• dig 8–12 inches wide
• dig at least 24 inches deep (sometimes deeper depending on soil/slope)
• add gravel at the bottom for drainage
• set posts plumb and square
• use concrete for stability

Common mistake: shallow posts lead to leaning fences after heavy rain.

5) Install Rails for Strength and Consistent Height

• measure rail height consistently across sections
• use exterior-rated screws or fasteners
• double-check level as you go

For most picket fences, two rails are standard (top and bottom), but some designs use three for extra rigidity.

6) Install Pickets with Consistent Spacing

• use a spacer block to maintain consistent gaps
• keep picket tops level (or follow the design pattern you choose)
• use stainless or coated fasteners to reduce rust staining

If you’re installing near a garden, slightly tighter spacing can help keep pets out and protect plants.

7) Add Finishing Touches That Upgrade the Look

• decorative post caps/finials
• a matching gate with upgraded hinges/latch
• staining or painting for protection and style

Finials and post caps also help keep moisture out of the post tops, which can extend fence life.
