Road Right-of-Way / Road Area Calculator

Calculate right-of-way area and the area occupied by carriageway, footpaths and other components.

The component widths are planning inputs; negative residual area indicates the entered components exceed the ROW width.

How to use this calculator

What to enter

Enter or select the following as requested: Road length; Total ROW width; Carriageway width; Footpath / verge width per side. Follow the units, valid ranges, examples, and options displayed beside each field.

What the result means

The area result estimates the two-dimensional surface covered by the dimensions entered. Check the displayed unit (for example, square metres or square feet) and whether openings, slopes, or waste allowances are included.

When to use it

Use this to estimate surface area for planning, material quantities, space measurement, or land measurement. Confirm that all dimensions use compatible units.
