The map above is centered on Paris, France, near the Hôtel de Ville, 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 the centre reaches La Défense (~9 km northwest) and into the inner banlieues of the petite couronne. Paris is compact for a major capital — a 5 km radius from the centre reaches the Eiffel Tower (~4 km west), Montmartre (~4 km north), and Père Lachaise (~3 km east). For the broader Île-de-France region, use a 25 km radius. For RER and Métro reach, the Drive Time Map is more useful than a circle. Distances here are straight-line from the Hôtel de Ville — the same way the radius map measures them.
Population figure: INSEE, population de référence 2022 for Paris (reference date 1 January 2022).
The City of Paris (intramuros) is bounded by the Boulevard Périphérique, a near-circular ring road. A 5 km radius from the centre fits the entire 20 arrondissements inside the Périphérique.
Also known as: Paname (slang), La Ville Lumière, Paris intramuros.
Coverage at common radii, including notable places that fall just outside the circle. Use these as a quick reference — check exact boundaries before relying on a circle for real-estate, retail, or service-area decisions.

A 1 km radius from the centre covers the historical core — the Hôtel de Ville, the Île de la Cité, Île Saint-Louis, the Latin Quarter, and the eastern edge of the Louvre.
A 5 km radius from the centre reaches the Eiffel Tower, Montmartre, Bastille, and Père Lachaise — the historic arrondissements inside the Boulevard Périphérique.
A 10 km radius reaches past the Périphérique into the inner banlieues — La Défense and the inner edge of the petite couronne (the inner suburban ring).
A 25 km radius reaches out past Versailles and Saint-Germain-en-Laye, well into the petite and moyenne couronne.
A 50 km radius reaches deep into Île-de-France, out to Chantilly in the north and Disneyland Paris in the east, into the grande couronne.
City-specific scenarios where a radius is the right tool — and a sensible radius to start with.
To filter apartments around a central workplace, draw a 5 km radius from the office. Because Paris is compact, a 5 km circle from a central point covers nearly the whole area inside the Périphérique, which makes a clean apartment-search boundary.
Suggested starting radius: 5–7 km for inner Paris
To estimate a shop's walk-in catchment, draw a 1–2 km radius (roughly a 15-minute walk) for daily footfall, and a 5 km radius to see how far a destination store might pull across the city. Adjust the radius to match how far your own customers typically travel.
Suggested starting radius: 1–2 km for daily footfall, 5 km for destinations
A 25 km radius from the centre reaches Versailles (~17 km west) and Saint-Germain-en-Laye (~20 km west) — a useful line for separating a tighter "Paris" delivery zone from a wider regional Île-de-France zone. Set the exact radius to match your own service commitment.
Suggested starting radius: 25 km for the inner region
For a venue within walking distance of a central guest-hotel cluster, a 1 km radius keeps everything on foot. For château venues out of town, a 50 km radius captures the area around Chantilly (~38 km north) and Versailles (~17 km west).
Suggested starting radius: 1 km (city), 50 km (château ring)
Local geography and infrastructure that change how a radius behaves here. Skipping these is the most common reason a radius decision goes sideways.
Paris (intramuros) is bounded by the Boulevard Périphérique, a ring road that traces the line of the city's 19th-century fortifications. Anything outside the Périphérique is technically banlieue, with separate administration.
Central Paris sits on the Seine, which curves through the city, so the river crosses a radius drawn from the Hôtel de Ville more than once. When you draw a circle, note which bank each landmark falls on — the river is a natural reference line, not a boundary the circle respects.
In Paris a radius from the centre works mainly as a catchment shorthand. Drive-time and walking-radius tools tell you less here than they would in a sprawling city; the radius mostly works as a catchment shorthand.
A 5 km radius from the centre reaches the Eiffel Tower (~4 km west), Montmartre (~4 km north), Bastille (~1 km east), and Père Lachaise (~3 km east) — the historic arrondissements inside the Boulevard Périphérique.
A 10 km radius reaches past the Périphérique to La Défense (~9 km northwest) and the Bois de Boulogne (~8 km west) in the inner petite couronne. Versailles (~17 km west) lies outside the radius.
Versailles is about 17 km west of the centre. A 10 km radius misses it, but a 25 km radius covers it comfortably along with Saint-Germain-en-Laye (~20 km west).
The City of Paris (intramuros) is bounded by the Périphérique. The wider Paris region (Île-de-France) is much larger, reaching out to places like Chantilly (~38 km north) and Fontainebleau (~56 km southeast).
Draw a 5–7 km straight-line radius from a central workplace as a rough stand-in for a short Métro commute. For wider RER (regional express) reach, expand the radius to 15–20 km, or use the Drive Time Map.
Paris (intramuros) is bounded by the Périphérique, which traces the line of the city's old fortifications, and the legal city limits have stayed compact — small enough to fit inside a 5 km radius. The surrounding Île-de-France region is far larger.
