How to use the multi-stop route calculator
- 1Add your stops
Add stops in order by address search or by clicking the map.
- 2Measure each leg
Each leg is measured as a straight-line distance on the ellipsoid and added to the running total.
- 3Read the trip total
See each leg's distance and bearing and the total, with an option to include the return to the start.
How multi-stop route distance is calculated
Unlike a simple two-point measurement, a multi-stop route represents a piecewise curve composed of discrete geodesic arcs strung sequentially across the Earth's surface. Whether calculating a delivery route, an aviation flight plan, or a hiking expedition, the total distance is the exact mathematical summation of all consecutive leg lengths:
Each individual leg maintains its own initial forward azimuth, curvature, and midpoint. On spherical and ellipsoidal models, the sum of geodesics between intermediate waypoints is always greater than or equal to the direct geodesic connecting the initial departure point directly to the ultimate terminus.
Does stop order matter? Fixed order vs. optimized route
A frequent source of confusion in multi-point travel planning is the distinction between an ordered itinerary and an optimal route (the classic Traveling Salesperson Problem, or TSP):
- Preserved User Sequence: Open Map Lab preserves your exact designated sequence of waypoints. If you specify Stop A → Stop B → Stop C, our engine computes the precise cumulative distance along that specific itinerary.
- NP-Hard Complexity of Optimization: Finding the absolute shortest possible order among 20 random stops requires evaluating 20! (over 2.4 quintillion) factorial permutations. While TSP heuristics approximate minimum spanning trees, real travellers frequently have non-negotiable delivery deadlines, appointment times, and hotel bookings that make rigid sequential calculation necessary.
Measuring a round trip or loop route
By activating the Close Loop option, the calculator adds a final leg connecting your last waypoint back to your starting coordinates. This transforms an open route into a closed geodetic polygon, enabling:
- Boundary Perimeter Audits: Rural landowners and fence installers can trace corner fence posts to establish exact property line perimeters.
- Athletic Training Circuits: Marathon race directors and cycling event planners can estimate closed loop lengths from straight-line legs between the points they place (road routing is not included).
- Round-Trip Fleet Fuel Budgeting: Logistics managers can forecast exact round-trip depot mileage for return-to-base commercial vehicle operations.
Example: a three-stop route, leg by leg
Examine the multi-segment calculation connecting three major hubs: Atlanta (ATL), Charlotte (CLT), and Nashville (BNA):
Total Distance = d(ATL, CLT) + d(CLT, BNA) + d(BNA, ATL)- Leg 1 Distance: d(ATL, CLT) = 226.43 statute miles (364.40 km)
- Leg 2 Distance: d(CLT, BNA) = 328.67 statute miles (528.94 km)
- Cumulative Open Route (ATL → CLT → BNA) = 226.43 + 328.67 = 555.10 miles
- Leg 3 Closure Leg: d(BNA, ATL) = 214.15 statute miles (344.64 km)
- Total Closed-Loop Perimeter = 555.10 + 214.15 = 769.25 statute miles
The cumulative straight-line perimeter of the triangle. Comparing this with the direct 2-point flight gives the exact geometric perimeter of the circuit.

Straight-line vs. driving distance: limitations
Be aware of the following technical considerations when evaluating multi-stop itineraries:
- Road vs. Direct Line: This tool calculates geodesic air distances. Ground transit through turnpikes, mountain switchbacks, and urban detours will yield higher cumulative miles.
- Order Dependency: Rearranging the order of intermediate waypoints can dramatically alter total distance. Verify your waypoint order reflects your intended travel sequence.
- Earth Spheroid Curvature: Long-distance multi-leg routes spanning hemispheres must be evaluated on the WGS84 ellipsoid to avoid Euclidean projection artifacts.

Edge cases and exceptions
Traveling Salesperson Optimization
This calculator evaluates your route in the exact sequence specified. It does not automatically reorder waypoints into an optimized TSP circuit, ensuring your chosen travel itinerary is preserved.
Water Body Crossings
Leg distances represent direct geodesics between waypoints. For maritime or mountain hops, actual road journeys may require ferries or bridges.

Frequently asked questions about the multi-stop route calculator
Can I add or remove stops dynamically?
Yes. You can add new stops by searching an address or clicking the map, and remove individual waypoints with a single click.
What is the round-trip loop feature?
Toggling "Close Loop" calculates the return leg from your last waypoint back to Point A, useful for delivery routes, marathon circuits, and property perimeters.
Does this find the best order of stops?
No. The tool totals distance in the order you enter the stops. Reorder them to compare routes; for many stops, optimization needs a routing engine.
Does the total include road travel?
The distance is the sum of straight-line (geodesic) legs, so real road mileage will be higher. Use it for planning and perimeter measurements.
How many stops can I add?
You can add several stops by address or by clicking the map. For large matrices, use the distance matrix calculator.
How do I measure the perimeter of an area?
Add the corner points in order and turn on the round-trip option so the route closes back to the first point.
Can I use it for a road trip budget?
Multiply the estimated mileage by your vehicle's fuel use and price, and add 15 to 25 percent for road detours.
What is a leg?
A leg is the segment between two consecutive stops. The tool lists each leg's distance and compass bearing.
Can I save or export the route?
You can copy the leg table and total. For a map file, use the map drawer or pin drop tools to export points.
Does the order of stops change the total?
Yes, significantly. Visiting the same stops in a different order can change the total by tens of percent.
