Slatted Fence Calculator

Choose your slat style

Both options are smooth, pressure-treated timber. The narrower slat creates finer lines; the wider slat gives a bolder finish.

Enter your fence measurements

Measure each connected side separately. This gives a more realistic quantity than treating corners as one continuous length.

Please check your figures. This calculator provides an estimate. Site measurements, timber cuts, gaps, corners, wastage and installation methods can all affect the final quantity.

Add recommended supports and fixings

We recommend a vertical support at maximum 1m centres. Choose 4×2 or 3×2 treated timber, or tell the calculator you already have suitable supports.

Support timber lengthChoose a length suitable for your installation. Posts set into the ground require additional length below the finished fence.
