We're working on it... in the meantime feel free to get in touch with one of our technical experts for assistance with planning your project by calling 0208 088 4888.
  • A drawing to scale may help you determine how much more material will be required
  • Always round up the number of materials required
  • For multiple fencing areas, follow the steps for each section and sum the quantities together
  • If your design is sloped, it is recommended that you add at least 5% to the total fence slats required for wastage
  • The type of foundation underneath the proposed fencing area will determine the post substructure needed to support the fence

Calculating how much fencing you need

Step 1

Calculating Fencing Areas
Start off by measuring the length and height of your proposed fencing area(s).

Step 2

Once you have your fence length, divide this by the length of a full fence panel and post (we recommend using a height of 1.8m).
The following example will use a fencing area of 1.8m long x 1.8m high:
Length = 18m, then 18m / 1.8m = 10 fence panel sections.

Step 3

Simply order this amount of complete fence panels on our website and all the required material will be delivered to the site.

Calculating fences with a height below 1.8m

If you require a fence height less than 1.8m or have existing fence posts, then you need to divide the required fence height by the height of a fence slat (0.162m) and multiply this by the amount of complete fence sections (1.8m wide) you require.
The following example will use a Fencing area of 19m wide x 0.80m high:
Height = 0.80m, then 0.80m / 0.162m = 5 fence panel boards per section.
10 fence panel sections x 5 fence boards per section = 50 fence panel boards.
