# How many feather boards do I need?

**how many boards**are

**needed**: Allow 12

**boards**per metre when using 100mm

**boards**. Allow 10

**boards**per metre when using 125mm

**boards**. Allow 8

**boards**per metre when using 150mm

**boards**.

Hereof, how do I calculate how much fencing I need?

Add the slat or picket spacing to the width of each one, then divide this number into the total length of the **fence** to find the number of slats or pickets you **need**. For example, if you're using 6-inch slat, which is 5 1/2 inches wide, and you're spacing them by 1/2 inch, you **need** 400 of them for a 200-foot **fence**.

**you**only use

**one**nail per pale per rail (i.e. 3 nails) -

**do**not nail two pales together. The single fixing is to allow the pales to expand and contract with the weather. As the top of the fence is continuous, capping

**can**be any length.

Accordingly, how much do you overlap feather edge boards?

**Feather**-**edge** cladding **is** designed to be laid horizontally with a vertical **overlap** of approximately 40mm for **boards** up to 150mm, and 50mm for **boards** wider than 150mm. It **is** important to follow fixing advice, particularly when using green (wet) timber.

To find this multiply the width of the floor-**board** in feet times the length in feet. You can use our feet and inches **calculator** to convert the **board** width in inches to feet. To find the number of **boards** you **need**, divide the total deck square footage by the **board** square footage, eg. total ft^{2} / **board** ft^{2}.
