About This Tool
How It Works
This calculator measures the straight-line (as the crow flies) distance between two UK postcodes using precise GPS coordinates. Enter any two valid postcodes to find the distance in miles and kilometres.
Common Uses
The postcode distance calculator is useful for estimating travel distances for commuting, planning deliveries and logistics, calculating removal costs, checking distances for job applications or school catchment areas, and working out mileage for expenses claims.
About the Calculation
The distance shown is the straight-line distance calculated using the Haversine formula, which accounts for the Earth's curvature. Actual road or travel distances will typically be 20-40% longer depending on the route.
