Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Timbers per course and run = round up (run length ÷ stock length). Multiply by run count and courses, add waste, and round to full timbers. Butt joints determine the modeled anchor count.
FAQ
Landscape Timber Calculator questions
Can offcuts be shared between runs?+
This calculator rounds each equal run and course independently, which is conservative when offcuts cannot be reused efficiently.
Are corner overlaps included?+
Use the waste and extra-anchor fields for simple corner details. Complex interlocking corners should be measured separately.
Can landscape timbers be used for any retaining wall?+
No. Wall height, drainage, soil loads, durability and local requirements determine whether the system is appropriate.
