To measure a mile on your phone, use the Google Maps app on either iPhone or Android. The app's built-in Measure distance tool lets you plot a route and displays the total in miles (mi) and kilometers (km) at the bottom of the screen.
How to measure a mile on your phone with Google Maps
Google Maps provides a verified, step-by-step method for measuring a route distance on both iPhone and Android devices. This is the primary way to measure a mile on your phone for walking, running, or cycling.
- Open Google Maps.
- Touch and hold a spot on the map that is not a place name or icon until a red pin appears.
- Tap Measure distance.
- Move the map so the black circle is on the next point you want to add.
- Tap Add point at the bottom right.
- Repeat to build the path; the total distance appears at the bottom in mi and km.
- When finished, tap the back arrow in the top left.
This method works on iPhone, iPad, and Android phones and tablets. The Google support page does not state a maximum number of points or a route-length limit.
Why not use Apple's Measure app?
Apple's built-in Measure app is designed for nearby physical objects, not route distance. Apple's Measure app is in the Utilities folder on iPhone. The Apple support page for Measure instructs you to open the app and use the camera to scan nearby objects. To use Apple's augmented reality measure app in iOS 12, you point the camera at a physical object to get its dimensions; it cannot measure a mile of walking or running route.
Alternative methods for measuring a mile
If GPS is unavailable or you prefer a different approach, several non-GPS methods can help you measure a mile on your phone.
Using pedometer apps for step-based measurement
Pedometer apps use your phone's motion sensors to count steps. By setting your step length based on your height and stride, the app estimates the distance you have covered. To measure a mile, multiply the number of steps by your step length.
Estimating distance based on pace and time
If you know your average pace, you can calculate distance from elapsed time. For example, if you walk at 3 miles per hour and walk for 20 minutes, you have covered approximately 1 mile.
Using known routes
If you have a specific route you frequently walk or run, measure its distance once using a GPS-based app. You can then use that route as a reference for future measurements, incorporating landmarks along the way to track your progress.
Tips for getting the most accurate measurement
To maximize accuracy when using the Google Maps method, ensure your phone is stable during the measurement process. Position your phone securely on your body using an armband or waistband holder to minimize inaccuracies caused by motion or vibrations. For GPS-based measurements, a strong GPS signal improves accuracy, though factors like tall buildings or dense tree cover can affect precision. Calibrate your fitness tracking app regularly by measuring a known distance manually and comparing it with the distance logged by the app.
Frequently Asked Questions
Can I measure a mile on my phone without GPS?
Yes. Pedometer apps use your phone's motion sensors to count steps and estimate distance based on your step length. You can also estimate distance using your average pace and elapsed time.
Which app is best for measuring a mile on my phone?
Google Maps is the most reliable verified option for measuring a route distance on both iPhone and Android. It uses GPS and allows you to plot points to build a path.
Are there free apps for measuring distances on my phone?
Yes. Google Maps is free and includes the Measure distance tool. Many fitness tracking apps like Strava and Nike Run Club also offer free distance tracking features.
How accurate is measuring a mile with Google Maps?
Accuracy depends on GPS signal quality, atmospheric conditions, and surroundings like tall buildings or dense tree cover. Most smartphones have a margin of error within a few meters, making it suitable for casual use.
Can I use my phone to measure shorter distances, like in a room or a small area?
Many measurement apps include features to measure distances within a room or a small area, often using augmented reality or camera-based measurements. Some popular apps include EasyMeasure for Android and CamToPlan for iOS.
