Why Calculate Straight-Line Distance?
school School Admissions & Catchment
In the UK, many primary and secondary schools use "as the crow flies" (straight-line) distance as a primary criterion for their oversubscription policy. If a school is oversubscribed, places are often allocated to children living closest to the school based on this specific measurement.
Handy for parents checking if their home postcode falls within a school's historical catchment area.
business_center Business & Service Radius
Many businesses set their delivery zones or service areas based on a radius from their central location. Understanding the straight-line distance helps in:
- Determining delivery fee tiers.
- Verifying eligibility for local government grants or schemes.
- Calculating displacement for insurance or travel expense claims.
How It Works
This tool calculates the direct"straight line" distance (Great Circle distance) between two UK postcode locations. It uses the geographic coordinates (latitude and longitude) of the central point of each postcode area to perform high-precision calculations using the Haversine formula.
Step 1: Input
Enter two valid UK postcodes (e.g., SW1A 1AA and M1 1AE).
Step 2: Calculate
Our API fetches coordinates and calculates the distance immediately.
Step 3: Result
View the distance in both Metric (KM) and Imperial (Miles) units.
