Sales Territory Radius Planner
Define rough territory sizes by distance from a sales hub before refining with real roads.
By Aryan Khan, Founder & Editor · Updated October 2026
For example, a territory of 500 square miles drawn as a circle has a radius of 12.6 miles — the planner's answer when management asks 'how far will the rep actually have to drive?'
How to use Sales Territory Radius Planner
Circles first, roads second — size the territory before routing it:
The Sales Territory Radius Planner defines territory size by distance from a sales hub — enter the hub and a radius, or the area you need, and see the territory's size on the map — fair circles first, roads later.
- 1Set the hub.
- 2Draw territory radii.
- 3Compare coverage.
What people use Sales Territory Radius Planner for
1. Sizing territories from a target area
Management sets 500 sq mi per rep; the planner converts that to a 12.6-mile hub radius. The Sales Territory Area Calculator checks the resulting shapes.
2. Comparing branch reaches
Draw every branch's radius and the overlaps and dead zones stand up on the map — the Service Coverage Gap Viewer formalises the gap hunt.
3. New-hub siting
Slide a candidate hub and watch its circle swallow or strand the accounts that matter. Radius first, lease second.
4. Honest customer promises
'Within our service radius' becomes a drawn fact rather than a slogan — customers inside 12.6 miles of the hub are in, and the map can prove it.
Worked examples
A 25-mile hub circle around Chicago covers about 1,963 sq mi and takes in Oak Park (8.0 mi), Evanston (11.7) and Gary, Indiana (24.5) — while Naperville (28.4) and Joliet (33.7) sit outside. State lines do not bend circles.
1,000 sq mi ↔ radius 17.8 miles; 200 sq mi ↔ 8.0 miles. The square root is the whole trick: radius grows slowly while area gallops.
Area and radius equivalents
The planner's core conversion, computed both ways.
| Target area | Hub radius | Roughly |
|---|---|---|
| 200 sq mi | 8.0 mi | A metro patch |
| 500 sq mi | 12.6 mi | A suburban county pair |
| 1,000 sq mi | 17.8 mi | A small region |
| 2,000 sq mi | 25.2 mi | A multi-county territory |
Radius reach is straight-line. Real territories follow roads, and the planner's own framing says so — refine with drive-time tools before promises are printed.
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 Sales Territory Radius Planner:
- Decide geometric vs temporal reach before drawing anything: a 10 km circle and a 15-minute drive area answer different questions, and in car-dependent geography they barely overlap in shape. Circles for policy radii, isochrones for response promises.
- 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.
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 workspace draws a distance circle around a selected centre; it does not calculate administrative territories or customer assignments.
For source details, licences and model limitations, see Data Sources and Methodology.
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 workspace draws a distance circle around a selected centre; it does not calculate administrative territories or customer assignments.
- 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.

Frequently asked questions
Clear answers about the calculation, accuracy and appropriate use.
Fair workloads?
Radius is a starting sketch — pair with population and drive-time tools.
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.
How do I choose a fair radius?
Start from the target area or account load, convert with this planner, then compare across hubs. Equal areas are the fair baseline; account density adjusts from there.
Can two hubs share accounts in the overlap?
Policy decides; geometry reports. The planner shows the overlap plainly so the policy conversation happens with a map open.
What about a hub near the coast or border?
The circle still draws; half of it may be water or another country. Effective territory is the landward, legal part — the planner shows the circle, judgment trims it.
Miles or kilometres?
Both — European territories plan in km with the same square-root arithmetic.
Travel time instead of distance?
The refined second pass: drive-time catchments bend with roads and traffic. Radius planning is the honest first draft both methods share.
One hub or many?
As many as the plan has — draw them all and read overlaps and gaps off the combined picture.
Can I export the territory?
The radius and hub are the territory's definition; note them and any map tool redraws it. Boundaries for contracts deserve the drawn-region method.
seasonal territories?
Radii are cheap to redraw — seasonal plans can carry seasonal radii, with the dates written next to them so nobody sells last summer's map.
