Measuring Distances on Google Maps: The Practical Way
Google Maps has a built-in measuring tool that most people overlook. It's buried in the right-click menu, and it works fine for basic distances. Here's how to actually use it without fighting with the interface. Right-click anywhere on the map, select "What's here?", then click "Measure distance." A line appears. Click again to add segments. Click the origin point to close the loop or measure a return path. That's the entire workflow. Takes about 4 seconds once you've done it twice. The measurements appear in both miles and kilometers by default. If you're in the US, the miles show first. You can toggle the unit in Settings under Maps settings, but honestly, you'll just need to get used to reading both numbers side by side until it becomes automatic.
Here's something most guides don't mention: the tool measures straight-line (as-the-crow-flies) distance, not driving distance. I learned this the hard way when a client asked me to measure a property line and I gave them the road distance instead of the survey distance. The difference was about 0.3 miles on a 2.1-mile parcel. Minor on paper, devastating during a zoning dispute. If you need actual travel distance, use the directions feature instead. Type in a start and end point and it gives you driving, transit, walking, and cycling distances. The driving distance accounts for road curvature, which the measuring tool ignores entirely. Another thing worth knowing: the measuring tool doesn't always snap to the exact pixel you click. On zoomed-out views, a single click can shift your endpoint by 50 to 100 meters. Zoom in close before clicking. This matters if you're measuring something small like a garden plot or a parking lot. For longer distances spanning several miles, the rounding error becomes negligible, but why leave it to chance?
There's also a mobile version of the measuring tool, but it's slower and less precise than the desktop version. Touch inputs introduce enough error that I'd only recommend it for rough estimates. If you need anything accurate, use a computer. The precision difference is noticeable after you've measured more than five or six objects. One edge case I ran into recently: trying to measure distance across a body of water. The tool lets you click anywhere, even on water, but it won't give you a boat route. It just gives you the straight-line distance. If you need water travel distance, you're on your own. No built-in solution. I ended up using a nautical charting app instead, which gave me a proper route along navigable channels. If you're doing this repeatedly for work, consider the Google Maps API. It's free up to a certain number of requests per month, then you pay per call. But for occasional personal use, the built-in tool is more than sufficient and requires zero setup.

The tool won't save your measurements automatically. Close the tab and they're gone. If you need to reference something later, take a screenshot or write down the coordinates. Simple, but easy to forget when you're in a hurry.
