What to check
This calculation uses: Length, Width, Paver length, Paver width, Compacted base depth, Bedding sand depth, Waste allowance. It returns: Area with allowance, Whole pavers, Compacted base, Bedding sand, Edge restraint length.
Measure the paved boundary, not the whole plot. Calculate steps, drains, beds and permanent openings separately.
The paved area with cutting allowance is divided by the face area of one paver, then rounded up to a whole piece.
Check whether the listed paver size is the nominal module including a joint or the actual manufactured face size.
Curves, borders and mixed patterns create more offcuts than a plain rectangular running pattern.
Use the units beside each field. The values in the worked example are starting inputs; replace them with your measurements and the specifications of your material.
