How to Plan & Measure Your Fencing Project

Professional fencing advice from Surrey’s trusted independent timber yard.

1
Measure the Total Perimeter Length
Measure along the actual ground boundary in metres. If your boundary slopes or turns corners, measure each straight run separately for precision.
2
Choose Panels vs. Continuous Closeboard
Panels (6ft / 1.83m): Quickest to assemble; slot into concrete slotted posts or timber posts.
Closeboard (3m Bays): Built on site; superior strength, handles uneven/sloping ground seamlessly, and has zero visible panel gaps.
3
Allow 2ft (600mm) Ground Embedment
A standard 6ft fence requires an 8ft post to ensure 2ft is secured below ground level in solid concrete. This prevents wind throw and sagging.
4
Gravel Boards, Two-Pin Cleats & Fixings
Concrete gravel boards for closeboard fencing include 2 galvanized two-pin cleats and 2 M10 square plate washers per 3m board to securely pin both ends into morticed concrete posts.

Fencing Calculation Formula

Panel Runs (6ft / 1.83m Centres):
• Bays = Fence Run ÷ 1.83m (rounded up)
• Posts = Total Bays + 1
• Gravel Boards = 1 per bay

Continuous Closeboard (3.0m Bays):
• Bays = Fence Run ÷ 3.0m (rounded up)
• Posts = Total Bays + 1
• Arris Rails = 3 per bay
• 100mm Featheredge = 40 boards per bay
• 125mm Featheredge = 30 boards per bay
• Gravel Boards = 1 per bay (3.0m length)
• Concrete Board Fixings: 2 Two-Pin Cleats & 2 M10 Washers per board

Concrete Anchor:
• Post Mix = Posts × 1.5 (rounded up to nearest 20kg bag)

Frequently Asked Questions

Everything you need to know about timber and concrete fencing specifications.

What is the difference between Panel fencing and Continuous Closeboard?

Fence panels come pre-made in 6ft (1.83m) widths and slot easily into slotted concrete or timber posts. Continuous closeboard fencing is constructed on site using morticed posts, 3 horizontal arris rails, a gravel board, and overlapping vertical featheredge boards. Closeboard fencing is stronger, has no panel joins, and easily accommodates ground contours and slopes.

Why do concrete gravel boards for closeboard require cleats and washers?

Because continuous closeboard posts are morticed (not slotted), concrete gravel boards cannot simply slide down a channel. Instead, two-pin galvanized cleats slot into pre-formed holes on the morticed post and concrete board, bolted securely with M10 square plate washers. Our calculator automatically adds 2 cleats and 2 M10 washers for every 3m concrete gravel board.

Should I choose Concrete or Timber posts?

Concrete posts will never rot and provide the longest possible lifespan. Timber posts provide a natural, warm aesthetic that matches the panels. All Ctimber wooden posts are UC4 pressure treated for extended ground contact protection.

Why are gravel boards essential?

Gravel boards sit directly on the ground underneath your fence panels or featheredge boards. They act as a sacrificial moisture barrier, keeping your main fence structure elevated above wet soil and garden debris, drastically extending the life of your fence.

How many bags of Post Mix do I need per post?

We recommend 1.5 bags (30kg) of Post Mix for standard garden conditions, or 2 bags for end posts, gate posts, or high wind-load areas. Our calculator automatically applies this formula and rounds up to full bags.
