What is the standard gap for a picket fence?

The traditional gap for a picket fence is usually the same as the width of the picket itself (e.g. a 75mm picket with a 75mm gap). However, many UK homeowners prefer a tighter 50mm gap for better containment of small pets or a more solid appearance.

How many pickets do I need per metre?

If you are using 75mm pickets with a 50mm gap, you will need exactly 8 pickets per linear metre (1000 / 125 = 8). Always order a few spares for cuts at corner posts.

What is the best wood for a picket fence?

Pressure-treated softwood (Pine or Spruce) is the most common and cost-effective choice in the UK. For a more premium, long-lasting finish that requires less maintenance, Western Red Cedar or Siberian Larch are excellent alternatives.

Pointed vs Rounded tops: Which is better?

Pointed tops are traditional and help water run off, but can be sharp. Rounded (Capped) tops are softer and safer for areas where children play. Flat tops are modern but require a capping rail to prevent water from sitting on the end-grain and causing rot.

Aesthetic Tip: For a professional finish, use a **spacer block** cut to your desired gap width (e.g. 50mm). Hold the block against the last picket as you nail the next one to ensure perfect uniformity.

The Classic Charm of Picket Fencing

Decorative & Functional

Picket fencing (also known as palisade) is the quintessential UK front garden boundary. It offers a clear definition of property lines without blocking light or obstructing the view of the house.

Our **picket fence calculator** allows you to experiment with different picket widths and gap sizes to find the perfect aesthetic balance for your home.

Installation Masterclass

The secret to a beautiful picket fence is maintaining a level top line.

1. Set your posts and horizontal rails first.
2. Install the first picket at the end of the run, ensuring it is perfectly vertical with a spirit level.
3. Use a long straight-edge or a string line across the top of the fence to ensure every subsequent picket is set at the same height.
4. Use a wooden spacer block between pickets to keep the gaps identical throughout.

Rail Positioning

For a 0.9m (3ft) or 1.2m (4ft) picket fence, two horizontal rails are sufficient. Position the bottom rail 150mm from the ground and the top rail 150mm from the top of the pickets to prevent warping.

Ground Clearance

Never install your pickets touching the soil. Leave a gap of at least 50mm (2 inches) at the bottom. This prevents the timber from wicking up moisture and rotting prematurely.

Pro Tip: Pre-Painting

It is much easier to paint or stain your pickets and rails *before* you assemble the fence. Once the fence is built, it is incredibly difficult to reach the back of the pickets where they meet the rails.

Project Disclaimer

Material estimates are based on standard linear spacing. If your fence has many corners, you will need additional posts and likely a few more pickets to ensure the spacing looks consistent at the junctions.
