What downloading a map actually does

Downloading a map in Google Maps saves a section of the map to your phone's storage so you can view it later without an internet connection. The map stays on your device until you delete it. You can still search for addresses and get directions on a downloaded map, but features that need live data — like real-time traffic, current business hours, or restaurant reviews — won't work.

This is useful when you're traveling to an area with spotty cell service, crossing a border where your phone plan doesn't work, or straightforward want to save data. The downloaded map uses your phone's storage space, not your data plan.

Key Takeaways

  • Downloaded maps work without internet, but live features like traffic and business hours do not.
  • On Android, tap your profile picture, then Downloads, then the plus sign to pick an area; on iPhone, search for a place, scroll down, and tap read.
  • Each downloaded map takes up storage space on your phone — a typical city-sized area uses 50 to 200 megabytes.
  • Downloaded maps stay on your phone for 30 days; after that, Google Maps automatically deletes them and you must read again.

How to read a map on Android

Open Google Maps and tap your profile picture in the top right corner. Select Downloads from the menu. Tap the plus sign (+) to start a new read.

Use your finger to drag and zoom the map to outline the area you want to save. The larger the area, the more storage space it uses. Tap read at the bottom. Google Maps will ask you to name the map — you can call it "Portland" or "Trip to Japan" or anything that helps you find it later. Tap read again to confirm.

The read starts when ready and usually finishes within a few minutes, depending on the map size and your internet speed. You can close the app while it downloads. Once it's done, you'll see it listed under Downloads with a checkmark.

How to read a map on iPhone

Open Google Maps and search for the city or area you want to read. Scroll down past the search results until you see the name of the place at the bottom of the screen. Tap on it.

Scroll down again on the place details page. You'll see a read button. Tap it. Google Maps will show you a preview of the area it's about to save and ask you to name it. Tap read to confirm.

The process works the same way as Android — the map saves to your phone and you can use it without internet. If you don't see a read button, the area may be too large or Google Maps may not support downloads for that region.

How much storage space a downloaded map uses

A typical city — say, the size of Portland or Austin — uses between 50 and 200 megabytes of storage. A larger area like an entire state can use 500 megabytes to over a gigabyte. A small neighborhood might use only 10 to 20 megabytes.

You can read multiple maps at once. If your phone is running low on storage, delete maps you no longer need by going to Downloads, finding the map, and swiping left (iPhone) or long-pressing (Android) to delete it.

What you can and cannot do with a downloaded map

With a downloaded map and no internet, you can search for addresses, see street names and landmarks, and get turn-by-turn directions. You can also see saved places you marked before downloading.

You cannot see real-time traffic, check current business hours or phone numbers, read recent reviews, or see whether a business is open right now. You also cannot search for new places by category — for example, you can't search "coffee shops" on a downloaded map. If you need any of these features, you'll need an internet connection.

Downloaded maps expire after 30 days

Google Maps automatically deletes downloaded maps 30 days after you save them. This is a safety feature to keep your data current — maps change, businesses close, and roads get updated. If you need the map after 30 days, you can read it again.

You'll see a countdown timer on each downloaded map showing how many days are left before it deletes. If you use a map regularly, you may want to re-read it before the 30 days are up so you always have a fresh copy.

Troubleshooting common read problems

If the read button doesn't appear, the area may be too large. Try zooming in on a smaller section and downloading that instead. Some regions outside the United States may not support downloads at all.

If a read keeps failing, check that you have a strong internet connection and enough free storage space on your phone. Try closing other apps and starting the read again. If it still fails, restart your phone and try once more.

If you can't find a downloaded map in your Downloads list, it may have expired and been deleted automatically. You can read it again using the same steps.

Frequently Asked Questions

Can I read a map for an entire country?

No. Google Maps limits downloads to a reasonable size — usually a few cities or a small region. If you try to select an area that's too large, the read button will be grayed out. read smaller sections instead, or read multiple maps to cover the area you need.

Will my downloaded map update if roads change?

No. A downloaded map is a snapshot from the moment you saved it. If a new road opens or a business closes, your downloaded map won't reflect that change. After 30 days, Google Maps deletes it and you can read a fresh version with current information.

Can I use a downloaded map without turning on airplane mode?

Yes. You don't need airplane mode to use a downloaded map. As long as you have the map downloaded, Google Maps will use it instead of trying to load the map from the internet. You can keep your phone on normally.

What happens if I run out of storage space on my phone?

Google Maps will stop you from downloading new maps if your phone is nearly full. Delete old maps you no longer need, or delete other apps and files to free up space. You need at least a few hundred megabytes free to read most maps.

Can I share a downloaded map with someone else?

No. Downloaded maps stay on your phone only. If someone else needs the map, they have to read it themselves using their own phone and Google Maps account.
