Draw a circle to list the towns and cities inside it.
Place
Region
Distance
Population
Towns and cities with at least 5,000 people (and regional capitals) from GeoNames (CC BY 4.0), counted when their centre point is inside the circle. Populations are GeoNames' figure for the town itself, not its metro area, and the list leaves out smaller villages, so it isn't a count of everyone who lives in the circle.

How to list the postcodes in a radius
This page opens with a 5-mile circle in London and the Postcode districts inside a circle panel open. Type a postcode (LS1 4DY), a district (LS1) or a town in the search box and press Enter to move the centre, or click the map. Set the radius above the map in miles or, from the unit menu, kilometres. Several values separated by commas, such as 3, 5, 10, draw rings around the same centre; pick the circle to list from the Circle menu.
Each line of the table is a district with the nearest town and its straight-line distance from the centre. Download CSV saves the districts with their coordinates and distances; Copy list copies the district codes separated by commas, the format delivery platforms and ad tools accept.
How a district counts as inside
A district is listed when its position, the average of the positions of all its postcodes, falls inside the circle. City districts are small and the average sits near their middle. Rural districts in Scotland and Wales can stretch for 20 miles or more, so near the edge of the circle a district may be partly inside without being listed, or listed while partly outside. Widen the radius slightly to be safe, and check the map.
The districts come from Ordnance Survey’s Code-Point Open, updated four times a year, under the Open Government Licence. The list covers England, Scotland and Wales and is about 37 KB compressed, loaded only on this page. Nothing you type is sent anywhere.
