What downloading a map means
Downloading a map means saving map data to your device so you can view it without an internet connection. When you read a map, you are storing the streets, landmarks, and terrain information on your phone or computer's storage space instead of pulling it from the internet each time you open the app.
Most mapping apps — Google Maps, Apple Maps, Offline Maps — let you read specific regions ahead of time. This is useful when you are traveling to an area with poor cell service, crossing a border where data roaming is expensive, or straightforward want to reduce how much data your phone uses.
The downloaded map stays on your device until you delete it. You can use it as many times as you want without using any data, though some apps limit how long you can keep a downloaded map before it expires and needs refreshing.
Key Takeaways
- Downloaded maps work without internet, but the process and storage space needed depend on which app you use and how large the area is.
- Google Maps, Apple Maps, and other navigation apps have different read buttons and storage limits — check your specific app's menu.
- Downloaded maps take up storage space on your device, usually between 50 MB and 500 MB depending on the region size.
- Most downloaded maps expire after a few months and need to be refreshed to stay current with road and business changes.
How to read a map in Google Maps
Open Google Maps and search for the city or region you want to read. Tap your profile picture in the top right corner, then select Offline maps. Tap the plus sign and confirm the area you want to save. Google Maps will show you how much storage space it needs — usually 50 MB to 200 MB depending on the size of the region.
The read happens in the background and can take several minutes on a slower connection. You can close the app while it downloads. Once finished, you can open Google Maps offline and search within that region, though some features like real-time traffic and business information will not work without internet.
Google Maps keeps offline maps for 30 days. After that, the app will ask you to refresh the map to update road changes and new businesses. You can delete a downloaded map anytime by going back to Offline maps, tapping the region, and selecting Delete.
How to read a map in Apple Maps
Open Apple Maps and search for the city or area you need. Tap the information button (the circle with an i) in the bottom right. Scroll down and tap read. Apple Maps will show the storage size and let you choose the detail level — Standard uses less space, while Detailed includes more street-level information.
The read begins when ready and shows a progress bar. Unlike Google Maps, Apple Maps downloads happen faster on most devices. Once complete, you can use the map offline for navigation, though turn-by-turn directions and live traffic will not work without a connection.
Apple Maps keeps downloaded maps for as long as you want, but they become outdated over time. The app will notify you when a map update is available. You can delete a downloaded map by tapping the information button again and selecting Delete.
Storage space and device limits
Downloaded maps take up space on your phone or computer. A single city usually needs 50 MB to 150 MB. A larger region like an entire state can need 300 MB to 500 MB or more. Before downloading, check how much free storage your device has — most phones show this in Settings under Storage or About Phone.
If your device is running low on storage, delete old downloaded maps before adding new ones. You can also choose to read only the areas you actually need rather than entire regions. Some apps let you choose between Standard and Detailed versions, with Standard taking up less space.
Downloaded maps do not affect your phone's speed or performance. They sit in the app's storage folder and do not interfere with other apps or functions.
When downloaded maps stop working
Downloaded maps expire because roads change, businesses close, and new streets open. Google Maps expires offline maps after 30 days. Apple Maps does not set a hard expiration, but the data becomes less accurate over time. Other apps like Maps.me and Offline Maps have different expiration periods — check your specific app's settings.
When a map expires, the app will prompt you to refresh it. Refreshing downloads the latest version and replaces the old one. This requires an internet connection and takes a few minutes, just like the original read.
If you are traveling and cannot refresh before your trip, read the map again before you leave home. This ensures you have the most current road and business information.
Other apps for downloading maps
Maps.me is a free app that lets you read entire countries or regions. The downloads are smaller than Google Maps because Maps.me uses different data sources. Offline Maps (also called Maps Offline) works similarly and includes hiking trails and topographic information if you need them for outdoor navigation.
Garmin BaseCamp and similar GPS software let you read detailed topographic maps for hiking and outdoor use. These take up more storage space but include elevation data and trail information that standard navigation apps do not provide.
Choose based on what you need: Google Maps or Apple Maps for city navigation, Maps.me for international travel on a budget, and specialized apps for hiking or detailed terrain information.
Frequently Asked Questions
Can I read a map and use it without ever turning on my phone's location?
Yes. Downloaded maps work entirely offline and do not require location services to be turned on. You can view the map and search within it without your phone knowing where you are. However, if you want the app to show your current location on the map, you will need location services enabled.
What happens if I read a map and then travel to a different country?
The downloaded map stays on your device and works the same way. You can view it, search within it, and navigate using it without any data connection. If you need maps for the new country, read those regions before you arrive or while connected to WiFi.
Do downloaded maps use my phone's battery faster?
No. Using an offline map actually uses less battery than streaming map data from the internet. The app does not need to maintain a data connection, which saves power. GPS navigation will still use battery regardless of whether the map is downloaded or streamed.
Can I share a downloaded map with someone else?
No. Downloaded maps are stored in each app's private folder and cannot be transferred between devices or users. Each person needs to read the map on their own device using their own app.
How do I know if my downloaded map is current?
Check the app's offline maps section — most apps show the read date next to each map. If it has been more than a month or two, consider refreshing it before a trip. The app will usually notify you when a map update is available.
