Most people think Google Maps is just for shouting turn-by-turn directions when you’re late for a dental appointment. It’s not. There is a hidden "ruler" tool tucked away in the interface that lets you calculate the exact mileage or footage between any two points on the planet. Honestly, it’s one of the most underrated features Google ever built. Whether you’re trying to see if a marathon training route is actually 10 miles or you’re arguing with a neighbor about where the property line sits, knowing how to use google maps to measure distance is a legitimate power move.
It works everywhere.
The ocean? Yep. Your backyard? Definitely. The distance between your front door and the nearest Taco Bell? Easy. But here’s the thing: the process is slightly different depending on whether you’re clicking around on a laptop or tapping on a cracked iPhone screen.
The Desktop Method: Click, Click, Done
If you’re on a computer, you have the most control. Open your browser. Go to Google Maps. Now, find your starting point. This is where most people mess up—they try to use the search bar. Don't do that. Just find the spot on the map and right-click it.
A little menu pops up. At the very bottom, you’ll see "Measure distance." Click that. A small white circle appears. Now, click anywhere else on the map. Boom. A line appears, and a small box at the bottom of the screen tells you the total distance.
You can keep clicking to create a complex, jagged path. If you’re planning a hike through a local park and want to follow the winding trails precisely, just keep adding points. The total distance updates in real-time. If you click a point by mistake, just click it again to remove it. Or, grab a point with your mouse and drag it to adjust the line. It’s incredibly intuitive once you realize the tool isn't hidden behind three layers of settings menus.
Measuring on Mobile (iOS and Android)
The phone app is a bit more finicky. You don't have a right-click button, so you have to use the "long press" technique.
- Open the Google Maps app.
- Touch and hold anywhere on the map that isn't a labeled landmark or business. A red pin will drop.
- At the bottom, tap the name of the place or "Dropped pin."
- Look for the "Measure distance" option with the little ruler icon. Tap it.
- Now you'll see a black crosshair on the map. Slide the map around with your finger to move that crosshair to your next point.
- Tap the blue "plus" button (Add point) in the bottom right corner.
Repeat this until you’ve mapped out your route. The distance shows up in the bottom left. It’s a bit more "video gamey" than the desktop version, but it’s remarkably accurate.
Does it account for hills?
This is a big point of contention for hikers. When you use google maps to measure distance using the ruler tool, you are measuring "as the crow flies." This is Euclidean distance. It’s a straight line from point A to point B. It does not account for the curvature of the earth over short distances, nor does it account for elevation gain.
If you measure a mile up the side of a steep mountain, the ruler tool tells you the horizontal distance. It doesn't care that you’re gasping for air because of a 2,000-foot incline. For that, you’d need to use the "Directions" feature and select the hiking icon, which uses Google’s elevation data to give a more realistic "walking distance." But for pure geometric measurement? The ruler tool is king.
Why Accuracy Sometimes Wiggles
Google Maps uses a Mercator projection. This is a fancy way of saying they take a round earth and flatten it onto your rectangular screen. Because of this, shapes and distances can get a little distorted the closer you get to the poles. However, for most of us measuring a few miles in the suburbs or even across a state, Google’s algorithms compensate for this using the Haversine formula.

According to researchers at the International Journal of Health Geographics, Google Maps’ distance tools are generally accurate to within a very small margin of error—often less than 1%—assuming you’ve placed your points correctly. The real error usually comes from the human. If your finger slips on the smartphone screen and you miss the trailhead by fifty feet, your data is toast. Zoom in. Zoom in as far as the satellite imagery allows before you drop your points.
The "Area" Hack Nobody Uses
Here is a pro tip that most people overlook. If you use the desktop version to use google maps to measure distance and you eventually click back on your original starting point, you’ve "closed" the loop.
When the shape is closed, look at that little box at the bottom of the screen again. Not only will it show you the total perimeter distance, but it will also tell you the total area in square feet or square miles.
This is massive for homeowners. If you're trying to figure out how much sod to buy for the backyard or how much fertilizer you need, don't guess. Don't walk around with a physical measuring tape like it's 1985. Map out the perimeter of your lawn on Google Maps, close the loop, and let Google do the math. It’s literally free surveying software.
Common Glitches to Watch For
Sometimes the "Measure distance" option just... disappears. Usually, this happens if you’ve clicked on a "Place of Interest" (like a Starbucks or a museum). Google wants to show you the business hours and reviews for those spots, so it hides the measurement tool. To fix this, click a neutral, empty spot on the map first to clear the selection, then start your measurement.
Also, be aware of "Lite Mode." If your browser is old or your internet is terrible, Google Maps might switch to a stripped-down version. In Lite Mode, you can't measure distance. You'll know you're in Lite Mode if you see a lightning bolt icon in the bottom right or if the 3D globe view isn't working.
Real-World Scenarios
Think about drone pilots. Before they take off, they need to stay within the "Line of Sight" (VLOS) regulations set by the FAA, which is usually around 1,500 to 2,000 feet depending on conditions. Smart pilots use google maps to measure distance from their launch point to the edge of their flight zone before they even power up the rotors.
Boaters use it too. If you’re navigating a bay and want to know how far it is from the pier to a specific buoy—and you don't want to rely solely on your GPS's routing—the manual ruler tool gives you a quick, clean estimate of the open water distance.

Moving Forward With Your Data
Once you’ve got your measurement, what do you do with it?
If you're on a computer, you can actually print the map with the distance line visible. Just hit Ctrl+P (or Cmd+P). Google will format a nice, clean version of the map with the measurement data included. This is great for property disputes or planning community events like 5K runs.
The next time you're wondering how far that "short walk" to the beach actually is, don't rely on your "gut feeling." Open the app, long-press the start, and drag the line to the finish. You might find out your "2-mile walk" was actually 3.5 miles, which explains why your feet hurt.
Practical Next Steps
- Audit your fitness route: Measure your standard neighborhood walk today and compare it to what your smartwatch claims.
- Check your boundaries: Use the satellite view and the area tool to see exactly how many square feet your property occupies.
- Plan your commute: Measure the literal distance of a "shortcut" versus the main road to see if you're actually saving mileage or just moving faster.
- Clear the cache: If the tool feels laggy on your phone, clear your Google Maps app cache in settings to keep the crosshairs moving smoothly.
Using the distance tool effectively transforms a simple navigation app into a precise spatial calculator. It's about as close as most of us will ever get to having a professional surveyor's kit in our pockets.
