Real Estate
Find homes that fit a real-world commute
Buyers do not search by zip code — they search by what is reachable. A 20-mile radius around a workplace, school, or grandparent's house is a much better filter than a postal-code list, because it ignores administrative borders that do not match how people actually live.
Three concrete jobs:
- Commute filter. Draw a 30-minute drive-time isochrone around the buyer's office. Anything outside is off the table; anything inside is a short list. Use the Drive Time Map for this — a straight-line radius will mislead anyone living near a river or a large freeway gap.
- School-district overlap. Draw a radius around the desired school and intersect with current MLS listings. Agents can export the radius as KML and import it into their MLS or CRM.
- Comparable sales (comps). A 1-mile radius around the subject property is the standard appraiser definition for comparable sales. Use the Radius Map with miles, drop a pin on the address, and screenshot or export.
Pitfall: radius distance is not driving time. A 5-mile radius in suburban Houston covers 8 minutes of driving; the same radius in central Manhattan can mean 40 minutes. Show the isochrone where the difference matters.
Worked example: NYC radius map — mile-by-mile coverage from Times Square, including a comps radius walkthrough.
Delivery & Service Zones
Define a service radius your team can actually staff
Restaurants, couriers, locksmiths, plumbers, mobile mechanics, and HVAC techs all face the same question: how far from the depot should we accept jobs? A radius gives a clear answer that a customer-service rep can quote in seconds: "We deliver within 8 miles. Your address is 6.2 miles away — yes."
- Quote at point of order. Embed the radius circle on a website so customers see whether their address is in-zone before clicking buy.
- Tier pricing by ring. Define a 5-mile inner ring (free), a 5–10-mile ring ($5 surcharge), and a 10–15-mile outer ring (delivery negotiated). The same address-to-distance math powers all three.
- Plan staffing by drive time, not radius. A 15-minute drive-time isochrone is a better staffing signal than a 5-mile circle, because it accounts for traffic. Use the Drive Time Map for this; switch to Walking Radius Map for bicycle couriers.
Pitfall: defining the zone in the office and never revisiting it. Re-draw your isochrone after major route changes (new bridge, road closure, new dispatch hub). The map that worked last year may quietly cost you on-time rates today.
Worked example: LA radius map — why a 10-mile radius in LA can mean 20 minutes off-peak or an hour at rush.
Retail & Business Location
Estimate market reach before you sign a lease
Retailers, franchises, and gym operators rely on trade-area analysis: the area from which a location draws most of its customers. The classic primary trade area is roughly 70% of customers; the secondary trade area picks up another 20%. For a neighborhood store the primary radius might be 1 mile; for a destination retailer like a furniture warehouse it can be 30+ miles.
- Site selection. Stack candidate locations and draw the same radius around each. Compare overlap with the closest competitor, demographic pockets, and major employers.
- Market-size estimation. Pull population from the radius using a census-overlay tool (separate from this site), and you have a rough addressable population.
- Cannibalization check. If your existing store has a 5-mile trade area and the new candidate sits 4 miles away, you are dividing customers, not adding them. The visual overlap on a radius map makes the argument fast.
Pitfall: picking a fixed radius without checking the actual customer-distance distribution. A 3-mile radius is a starting hypothesis, not a law. If the data shows 70% of customers come from within 2.1 miles, that is your real primary trade area.
Worked example: Chicago radius map — uses a lake-corrected radius math because half of any circle on the lakefront is open water.
Event & Wedding Planning
Find venues that work for everyone's travel
Event planners use radius searches to constrain venue, hotel, and catering options around a center point — usually the ceremony location, the office, or the rough midpoint between the most distant guests.
- Hotel block within walking distance. A half-mile walking radius around the venue catches the hotels guests can leave on foot at the end of the evening — often the difference between a smooth night and ten Ubers at once.
- Reception within driving distance of ceremony. Most venues limit transit to 15–20 minutes between sites. Use a drive-time isochrone, not a radius, when the route crosses a bridge or highway.
- Corporate offsite midpoint. Map a radius around each attendee's home; the venues inside the intersection minimize total travel.
Pitfall: measuring straight-line distance to a hotel that is physically across a river or highway. A 0.4-mile radius can hide a 1.2-mile walk in dense urban grids. Switch to walking distance for anything inside a city.
Worked example: Paris radius map — compact-city geometry where a 1 km radius covers most central wedding venues.
Marketing & Local SEO
Define a service area that matches how you actually market
Local marketers use radii to scope geo-targeted ads, define service areas in Google Business Profile, and pick which neighborhoods to write local landing pages for. The radius is also the base unit of geofencing — see the Geofence Map Tool for that workflow.
- Google Ads geo targeting. Google lets you target a radius around a location. Drawing the same radius on a real map first prevents bidding on customers who are physically separated by a state line, water, or a highway you do not actually serve.
- Service-area Google Business Profile. Google asks for the cities or zip codes you serve. A radius map tells you which zip codes are inside your radius — which is what we built the Zip Code Radius for.
- Geofenced display advertising. A 0.5-mile geofence around a trade-show booth or competitor location triggers mobile ads only when devices physically enter that zone.
Pitfall: assuming Google's radius targeting and your business radius are the same. Google's radius is bidder-side; it does not know your actual reach. Decide your zone first, then enter it into Ads.
Worked example: London radius map — Tube zones map almost 1:1 to radius bands, a useful trick for local SEO targeting.
Sales Territory Mapping
Carve territories that balance opportunity with travel time
Field-sales orgs split the country into territories. Done badly, one rep covers an empty rural area while another fights through dense urban traffic. Radius mapping is the first cut: every prospect within 60 miles of rep A, every other prospect to rep B.
- Round-robin assignment. Drop a center pin per rep, draw radii, resolve overlaps by closest distance. Quick and good enough for early-stage teams.
- Travel-time-balanced territory. Use a drive-time isochrone instead of a straight radius. Reps in dense metros need smaller territories; reps in low-density regions can cover much larger areas in the same hours.
- Customer-density correction. Shrink radii where prospects are concentrated and expand where they are sparse. The goal is equal pipeline per rep, not equal area.
Pitfall: assigning territories by zip code clumps without ever looking at the map. Zip codes have wildly different sizes — one rep with 50 zip codes in Manhattan can have less land than another with 5 zip codes in Wyoming. The radius view exposes that immediately.
Worked example: Toronto radius map — shows why a circular radius distorts the linear east-west GTA territory.
