The map above is centered on Madrid, Spain, near Puerta del Sol, with a default 10 km radius. Drag to move it, search for a different address, or change the radius and unit using the controls.
A 10 km radius from Puerta del Sol reaches central landmarks and the inner suburb of Pozuelo de Alarcón (~9 km west). The M-30, M-40 and M-50 orbital motorways give you a quick mental model for inner, city-wide and outer-metropolitan rings, though each is an irregular loop rather than a perfect circle, so the actual distance varies by direction. Drive time inside the M-30 is heavily traffic-dependent — pair the radius map with the Drive Time Map for honest commute work. Distances here are straight-line from Puerta del Sol — the same way the radius map measures them.

Madrid is encircled by orbital motorways — the inner M-30, the M-40, the partial M-45 on the eastern side, and the outer M-50. Each ring roughly corresponds to a shift in urban character, so they make natural reference points when you draw a radius around the centre.
Also known as: Madriz (colloquial), La Capital.

A 1 km radius from Puerta del Sol covers the historical core of Madrid — the Palacio Real (~1 km west), the Gran Vía, and most of the central tourist quarter, with Plaza de España right at the edge (~1 km northwest).
A 5 km radius reaches Gran Vía (~0 km north), the Palacio Real (~1 km west), Casa de Campo (~4 km west), the Santiago Bernabéu Stadium (~4 km north) and the Chamartín district (~5 km northeast).
A 10 km radius reaches the central landmarks plus the inner western suburb of Pozuelo de Alarcón (~9 km west). Madrid-Barajas Airport (~14 km northeast) and the northern suburbs of Alcobendas (~15 km northeast) sit just beyond this ring.
A 25 km radius extends out to Madrid-Barajas Airport (~14 km northeast), Alcobendas (~15 km northeast), Las Rozas (~17 km northwest) and San Sebastián de los Reyes (~17 km northeast), all of which fall inside this ring.
A 50 km radius from Puerta del Sol reaches Alcalá de Henares (~30 km east) to the east and Aranjuez (~44 km south) to the south. Guadalajara (~51 km northeast) and Toledo (~66 km southwest) sit just beyond the edge.
City-specific scenarios where a radius is the right tool — and a sensible radius to start with.
Madrid's orbital motorways make convenient radius references. A smaller circle approximates the dense, walkable central city, while a larger circle approximates the wider city-wide area. Drawing both as a dual radius lets you split "central" from "wider city" at a glance.
Suggested starting radius: 5 km (M-30), 10 km (M-40)
A 10 km straight-line radius from a workplace in central Madrid reaches the inner-ring districts and inner suburbs such as Pozuelo de Alarcón (~9 km west). Use it as a starting catchment for a property search, then switch to the Drive Time Map to check how far that translates in actual commute time.
Suggested starting radius: 10 km for inner commuting
Madrid-Barajas Airport sits ~14 km northeast of Puerta del Sol. A 25 km radius comfortably includes it, and even a 15 km radius captures it — handy when scoping hotels, logistics, or anything that needs to stay close to the airport.
Suggested starting radius: 15–25 km to include Barajas
A 50 km radius reaches out to Alcalá de Henares (~30 km east) and Aranjuez (~44 km south). Use it to frame a regional commuter-belt search, then layer the Drive Time Map on top, since high-speed rail can make some towns beyond the circle faster to reach than driving.
Suggested starting radius: 50 km (regional belt)
Local geography and infrastructure that change how a radius behaves here. Skipping these is the most common reason a radius decision goes sideways.
Few cities are as cleanly ringed as Madrid: the M-30, M-40 and M-50 orbital motorways, plus the partial M-45 on the eastern side, wrap the city in concentric loops. Each ring roughly corresponds to a shift from central to inner-suburb to outer-suburb, which is why they work so well as informal radius references for trade-area work.
The orbital motorways are irregular loops rather than perfect circles, so a single radius will reach different neighbourhoods depending on direction. Draw the circle and check which named places fall inside on each side before you treat it as a trade area.
Spain's high-speed rail network radiates from Madrid, so some cities tens of kilometres away can be reached quickly by train. When you analyse the Madrid commuter belt with a radius, treat a straight-line circle as only the starting point and check rail connections for destinations on the network — the Drive Time Map helps with the road side.
A 10 km radius from Puerta del Sol reaches the central landmarks plus the inner western suburb of Pozuelo de Alarcón (~9 km west). Madrid-Barajas Airport, at ~14 km northeast, sits just outside it.
They are four orbital motorways encircling Madrid. The M-30 is the innermost ring around central Madrid, the M-40 wraps the wider city, the M-45 is a partial ring on the eastern side, and the M-50 is the outer metropolitan ring. Each makes a useful informal reference when you draw a radius around the centre.
Yes, comfortably. Barajas is about 14 km northeast of Puerta del Sol, well inside a 25 km radius. A 15 km radius also captures it.
A 5 km radius reaches Casa de Campo (~4 km west), the Santiago Bernabéu Stadium (~4 km north) and the Chamartín district (~5 km northeast), along with Gran Vía and the Palacio Real near the centre.
Both cities have well-defined inner-ring motorways — the Périphérique for Paris, the M-30 for Madrid — which make handy informal radius references. Draw the same radius on each and compare which named places fall inside to see how their footprints differ.
The orbital motorways follow Madrid's broadly concentric growth, so the M-30, M-40 and M-50 work as rough stand-ins for inner, city-wide and outer-metropolitan rings. Because each is an irregular loop, draw the circle and check the named places on each side rather than assuming an exact match.
