Service Area Map
Plan delivery or service coverage using distance and reach concepts on the map.
By Aryan Khan, Founder & Editor · Updated October 2026
For example, a 10-mile service ring around a depot covers 314 square miles — the map makes that either a confident promise or an obvious overreach, in one look.
How to use Service Area Map
Draw the reach you can actually keep:
A Service Area Map plans delivery or service coverage using distance and reach around a base — draw the ring, read the ground it covers, and judge the promise before customers test it. This page works in straight-line reach, the honest first draft that drive-time tools later refine.
- 1Set the centre.
- 2Choose coverage size.
- 3Inspect the area.
What people use Service Area Map for
1. Delivery zone design
Zones drawn by radius around the kitchen or depot are how delivery promises start. The Delivery Radius Area Calculator prices each ring's ground.
2. Trades and call-out coverage
Plumbers, locksmiths and appliance repair live inside a service ring — the map is the website's coverage page and the dispatcher's sanity check in one.
3. Franchise territory checks
A new outlet's ring overlapping an existing one's is visible instantly — the Service Coverage Gap Viewer takes the overlap analysis further.
4. Honest marketing
'We serve the metro area' becomes a drawn boundary customers can check — which is why the honest version outsells the vague one over time.
Worked examples
A 20 km ring around central Paris covers about 1,257 km² and takes in Saint-Denis (8.9 km), Orly (12.7) and Versailles (17.4) — a capital-sized promise that ring makes legible at a glance.
Customers just inside the ring get served; one street beyond, they don't. Drawing the ring forces the edge conversation before a disappointed caller has it for you.
Ring sizes around a base
What common service radii actually cover.
| Radius | Area covered | Feels like |
|---|---|---|
| 3 mi | 28.3 sq mi | A town and its edge |
| 5 mi | 78.5 sq mi | A small city |
| 10 mi | 314.2 sq mi | A metro core |
| 15 mi | 706.9 sq mi | A county-scale promise |
| 25 mi | 1,963.5 sq mi | A regional operation |
Straight-line area is the ring's geography, not its driveability — rivers, motorways and traffic bend real coverage, which the refinement tools account for.
A service area should match the rule your business actually uses
Service areas can be defined by straight-line radius, road distance, travel time, ZIP coverage or administrative boundaries. This tool is most useful when you clearly state which model represents your operation. A circular 20-mile area is easy to communicate, but it may overstate reach across rivers or mountains and understate reach along fast highways.
For customer promises, compare the planning map with real routing, staffing and delivery constraints. A service-area visualization is a screening tool unless it is backed by the exact eligibility rules used by your business system.
How to interpret the result
The most common errors come from using a correct result to answer the wrong geographic question. Keep these points in mind for Service Area Map:
- Verify areas against a known object first — measure a football pitch or a city block you know — and you'll calibrate your eye for what a hectare or acre looks like at your zoom. The map preview is the unit your intuition trusts.
- When exporting polygons for reports, store the radius and unit in the feature properties (the exports here do). Future-you, reopening the file in a GIS, will otherwise have to re-derive what the circle meant.
Limits & appropriate use
Circles and polygons are geometric truths with semantic limits. A radius says nothing about rivers, one-way systems or response times; an area says nothing about what is inside it. The most expensive misuse is treating a geometric catchment as a service promise — which is why the isochrone tools exist as the temporal counterpart, and why the pages cross-link the two insistently. A second limit is resolution: drawn vertices capture the boundary you click, so curved shores want more clicks, and the perimeter grows (correctly) as you add them — the coastline paradox, politely present in every honest measurement tool.
Within geometry, the numbers are exact on the sphere: areas by spherical excess, boundaries by destination math, exports with their parameters embedded. The escalation ladder is short: cadastral precision needs licensed surveys; population-inside-shapes needs census blocks; drive-time promises need the routing engine. Used as the fast, auditable, shareable geometric layer that feeds those heavier instruments, this is exactly the right tool — and it says so.
- Cadastral/legal area → licensed survey with local datum practice.
- Population inside shapes → census blocks, not city-point sums.
- Response-time promises → isochrones plus operational buffers.
Data & methodology
The current workspace draws a straight-line distance circle on a spherical Earth; it does not calculate road-network drive-time reachability.

Key terms worth knowing
- Catchment
- The area or population served from a centre, geometric or temporal.
- Perimeter
- The summed great-circle length of a drawn boundary.
Editorial guidance: MapBench explains the method and limitations so the tool can be used as a transparent reference, not as a black-box answer. For legal boundaries, safety-critical routing, surveying, engineering, regulated decisions or official statistics, verify the result with the responsible authority or a qualified professional.

Method, assumptions & limits
- This tool’s method
- The current workspace draws a straight-line distance circle on a spherical Earth; it does not calculate road-network drive-time reachability.
- Before relying on the answer
- Check the centre, radius or drawn vertices and the selected units. A geometric footprint does not describe which roads or entrances are accessible.
- What the result cannot establish
- A radius is not a travel-time guarantee. For parcel boundaries or legal land area, use an authoritative survey.
Coverage: Worldwide. Search, basemap and external data requests may use third-party services; browser-based does not mean every operation is offline.

Frequently asked questions
Clear answers about the calculation, accuracy and appropriate use.
Live traffic?
Radius is geodesic; pair with drive-time for road reach.
Is a radius the same as driving distance?
No. A radius is a geometric circle around a centre point. Driving reach depends on the road network and usually has an irregular shape.
Can I use this for service-area planning?
Yes for first-pass planning. Use a drive-time or road-network tool when accessibility matters more than straight-line coverage.
Are map measurements legal survey measurements?
No. MapBench measurements are planning/reference outputs unless a page explicitly states otherwise. Use a licensed surveyor for legal boundaries.
Does it use live traffic?
No — this map works in distance and reach, which do not change with the rush hour. Drive-time service areas are the refinement layer; the ring is the stable planning draft.
Multiple bases?
Draw each base's ring and read the union with your eyes; the coverage-gap tool analyses overlaps and holes between centres formally.
Rings or polygons?
Rings are the promise customers understand; polygons follow roads and boundaries for the operational version. Start with the ring, refine to the polygon.
What radius should I choose?
The one your operation can serve well on its worst day, not its best. The map shows candidates; your service times decide.
Customers just outside?
Policy, made visible: the map lets you set an outer enquiry ring ('ask us') beyond the guaranteed one — honesty with a door left open.
Kilometres for Europe?
Of course — the arithmetic is identical and the examples on this page run in both.
Can I put the map on my website?
The ring's definition (base + radius) is yours to publish however you draw it; a drawn boundary customers can verify is the trust asset.
Seasonal service areas?
Redraw and republish with dates — gardens and holiday trades honestly shrink and grow their reach across the year.
