The map above is centered on Berlin, Germany, near Alexanderplatz, with a default 10 km radius. Drag to move it, search for a different address, or change the radius and unit using the controls.
Berlin is geographically large for a European capital. A 10 km radius from Alexanderplatz roughly matches the S-Bahn Ringbahn — the orbital S41/S42 train line that traces the inner ring. This is a useful proxy for "central Berlin" in real-estate, retail, and event-planning work. Beyond the ring, the city continues for another 5–10 km in most directions before reaching the Brandenburg green belt.
Berlin covers roughly 891 km² — about the same area as New York City's five boroughs combined. A 10 km radius from Alexanderplatz roughly traces the S-Bahn Ringbahn, the inner ring line.
Also known as: Berlin-Mitte (centre), Hauptstadt.
Real coverage at the most-searched radii, including notable places that fall just outside the circle. Use these as ground truth before relying on a circle for real-estate, retail, or service-area decisions.
A 1 km radius from Alexanderplatz covers Mitte's eastern half — the TV Tower, the Berliner Dom, Museum Island, and most of the Nikolaiviertel.
A 5 km radius reaches Brandenburg Gate, the Reichstag, Tiergarten's eastern half, Kreuzberg, Friedrichshain, Prenzlauer Berg, Wedding's southern half, and Charlottenburg's eastern edge.
A 10 km radius from Alexanderplatz roughly matches the S-Bahn Ringbahn (S41/S42) — the orbital ring that defines "inner Berlin". Includes most of Charlottenburg, Schöneberg, Tempelhof-Schöneberg, Neukölln (north), Treptow (north), and Pankow (south).
A 25 km radius covers all of Berlin (the city extends ~45 km east-west and ~38 km north-south, so a 25 km radius from the centre captures most outlying districts) plus BER Airport and the inner Brandenburg ring.
A 50 km radius reaches well into rural Brandenburg — Oranienburg fully, Bernau, Fürstenwalde's western edge, Potsdam fully, and the lake districts of Spree-Neiße. Covers most of the Berlin commuter belt.
City-specific scenarios where a radius is the right tool — and the typical radius sizes professionals use.
Berliners often filter property by "innerhalb des Rings" (inside the Ringbahn) — a status-laden 10 km radius from the centre. This roughly corresponds to walkable Berlin and rules out the suburban GDR-era housing estates.
Typical radius: 10 km (inside the Ringbahn)
Berlin's 12 Bezirke (districts) are administratively important but unevenly sized. A 5 km radius from any inner-city centre typically covers 3–5 Bezirke — useful for retail trade-area work that crosses administrative boundaries.
Typical radius: 5 km for inner-city Bezirk catchment
BER Airport sits about 25 km southeast of Alexanderplatz, on the city's outer edge. Hotel and ground-transport operators use a 25 km radius as the airport-inclusive zone for shuttle and tariff planning.
Typical radius: 25 km for airport-aligned service zones
Berlin's commuter belt extends 30–60 km into Brandenburg via S-Bahn and regional rail. A 50 km radius captures most weekday commuter traffic and the second-home market around Potsdam, Oranienburg, and the lake districts.
Typical radius: 50 km for Brandenburg commuter belt
Local geography and infrastructure that change how a radius behaves here. Skipping these is the most common reason a radius decision goes sideways.
Berlin's 891 km² is roughly the same area as New York City's five boroughs (789 km²) and substantially larger than Paris intramuros (105 km²). A 10 km radius from the centre is genuinely "inner Berlin", not "all of Berlin".
The S-Bahn Ringbahn (S41 and S42) is a 37 km circular railway around inner Berlin. A 10 km radius from Alexanderplatz roughly traces this ring. Berliners use the Ringbahn as the dividing line between dense inner districts and outer ones — much like London uses Zone 1, but on a single train line.
Unlike most major cities, Berlin's radius math is not significantly affected by water or traffic — the city is on a glacial plain with scattered lakes (Wannsee, Müggelsee) but no big river or harbour bisecting it. Distance is a reasonable proxy for travel time, especially via S-Bahn and U-Bahn.
A 10 km radius from Alexanderplatz roughly matches the S-Bahn Ringbahn — the orbital S41/S42 train line that traces inner Berlin. It covers most of Mitte, Kreuzberg, Friedrichshain, Prenzlauer Berg, Charlottenburg, Schöneberg, and Neukölln.
A 5 km radius from Alexanderplatz covers the Brandenburg Gate, Reichstag, Tiergarten, Kreuzberg, Friedrichshain, Prenzlauer Berg, and the eastern edge of Charlottenburg. Tempelhof Field and the Olympiastadion are outside.
Berlin is much larger by area. The City of Paris fits inside a 5 km radius, while inner Berlin (the Ringbahn) requires a 10 km radius. Berlin's 12 Bezirke spread across 891 km², compared to Paris's 20 arrondissements in just 105 km².
Yes. BER Airport sits about 25 km southeast of Alexanderplatz, just inside a 25 km radius. A 20 km radius would miss it. For airport-inclusive shuttle and ground-transport zones, 25 km is the standard.
It means "inside the S-Bahn Ringbahn" — the orbital S41/S42 train line at roughly a 10 km radius from the centre. Berliners use it as a status-laden divider between walkable inner districts and the outer ones. Real-estate listings and lifestyle articles use the phrase frequently.
Berlin's commuter belt extends 30–60 km into Brandenburg via S-Bahn (S1, S5, S7) and regional rail. A 50 km radius from Alexanderplatz captures Oranienburg, Bernau, Fürstenwalde, and most of Potsdam — the practical commute zone.
