Calculate an approximate radius around Montreal, Canada. Use an illustrative reference point near Central Montreal; the circle measures straight-line distance rather than commute time.
Montreal: draw a 10 km radius
Start from Central Montreal, change the radius or center, then export a GeoJSON circle. The starter map covers approximately 314.16 km² on a flat-circle approximation.
What makes the Montreal map different?
The island geography of Montréal makes bridges important for any travel-based area analysis.
As a practical example, a company might draw this circle to screen places for a service area. That does not prove those places can be reached within a particular time. Road, ferry and transit routes should be checked separately.
How to use this city radius map
- Review the starter coordinate near Central Montreal.
- Change the radius or switch miles and kilometers.
- Click another point on the map to reposition the center.
- Copy a shareable link or export GeoJSON for a GIS workflow.

Frequently asked questions
Does this circle follow roads in Montreal?
No. The map calculates distances along the Earth's surface, not drive time or route distance.
Can I move the center away from Central Montreal?
Yes. Click the map or enter a new coordinate to reposition it.
Does the calculated area equal developed urban land?
No. The circle may include water, fields, mountains and neighboring municipalities.
Can I share the map?
Yes. Use the Copy link control to share a prefilled map with coordinates and radius.
Accuracy: spherical-Earth approximation, city point manually curated. Content and coordinates require local editorial verification before publishing city-specific pages. Calculation methodology.
Montreal: local radius reference
Use the location near Central Montreal to start a circle in Montreal, Canada. This is a chosen map reference point and may differ from the official administrative center or the metro region. The island geography of Montréal makes bridges important for any travel-based area analysis.
| Setting | Value / how it was computed |
|---|---|
| Start coordinates | 45.5017, -73.5673 |
| Default radius | 10 km |
| Approximate area | 314.16 km² (πr²) |
| Half radius area | 78.54 km² |
| Double radius area | 1,256.64 km² |
Location-specific interpretation
The island geography of Montréal makes bridges important for any travel-based area analysis. A circle remains a geometric screen rather than a serviceability guarantee. Compare the center with a local street map before planning delivery, relocation or commercial coverage.
Frequently asked questions about Montreal radius maps
What does a 10 km radius around Montreal mean?
It includes points no farther than 10 km in straight-line geographic distance from the example coordinate near Central Montreal.
Is the default map point the official center of Montreal?
No. It is an illustrative landmark or reference coordinate (45.5017, -73.5673), not a published municipal centroid or an official city boundary.
How much area is covered by this radius in Montreal?
About 314.16 square kilometers using πr², before considering curvature, water or route barriers.
Does this radius show a Montreal driving zone?
No. Roads, travel speed, restrictions, water crossings and terrain require a routing/isochrone service.
Can I increase the map radius around Montreal?
Yes. Choose another radius in the calculator to see a different straight-line circle; do not assume all settings are preserved by third-party services.
Can I change the map center away from Central Montreal?
Yes. Click a new point or enter coordinates supported by the map calculator.
Why can the Montreal circle include places outside the city?
A radius follows distance from one point and does not stop at municipal or national boundaries.
Does the circle include population or ZIP-code totals?
No. That requires an additional validated population or postal geography layer that is not part of this area calculation.
Are the Montreal radius coordinates verified survey coordinates?
No. These are manually curated example coordinates; validate the site before business or safety-related use.
Can I download a Montreal circle for GIS?
The core map calculator supports geographic geometry export where the corresponding control is active. Check exported coordinates and CRS in your GIS software.
Sources and validation: coordinates are supplied as illustrative internal starter points; spherical radius formulas use elementary geometry and Earth measurement. For underlying map context see our methodology. Live city geocoding needs separate provider validation.
