Google Maps can use anywhere from a few hundred megabytes to several gigabytes on your phone, mostly from offline maps you downloaded and a cache of tiles and imagery. You reduce it by deleting unused offline areas and clearing the app's cache or data.
Short answer:
- Delete unneeded offline maps in Google Maps under your profile > Offline maps.
- Clear the app cache: Android via app settings, iPhone by offloading or reinstalling.
- Set offline maps to download over Wi-Fi only so they don't quietly grow.
Where Google Maps Storage Goes
Two things drive Google Maps' footprint. First, offline maps: regions you downloaded for navigation without data, which can be hundreds of megabytes each for a single city. Second, the cache, the map tiles, satellite imagery, Street View, and search data the app stores so frequent areas load instantly.
To see the total on Android, go to Settings > Apps > Maps > Storage & cache, where the app data and cache are listed separately. On iPhone, open Settings > General > iPhone Storage > Maps to see App Size versus Documents & Data.
If the number is large, offline maps are usually the bigger chunk, and they're the easiest to manage directly inside the app.
Step 1: Delete or Trim Offline Maps
Offline maps are the cleanest win because Google gives you direct control.
- Open Google Maps and tap your profile picture in the top-right.
- Tap Offline maps.
- You'll see every downloaded region with its size. Tap the three dots next to any you no longer need and choose Delete.
Keep only the areas you genuinely travel. A downloaded map also auto-expires after about a year unless refreshed, so old ones may be lingering uselessly. Deleting them frees their full size immediately.
Step 2: Set Offline Map Preferences
While you're in Offline maps, tap the gear icon (settings) to control future growth.
- Set Download preferences to Over Wi-Fi only so maps never download over cellular and don't balloon unexpectedly.
- Enable Auto-update offline maps only if you rely on them, otherwise stale maps just take space.
- Choose Auto-download recommended maps carefully, turning it off prevents Maps from grabbing regions you didn't ask for.
These settings keep offline storage intentional rather than creeping upward on its own.
Step 3: Clear the Google Maps Cache
The cache rebuilds as you use the app, so clearing it is safe and reversible.
- Android: Go to Settings > Apps > Maps > Storage & cache > Clear cache. Avoid Clear storage unless you want to reset your offline maps and preferences too.
- iPhone: iOS has no per-app cache button. Open Settings > General > iPhone Storage > Maps and use Offload App (keeps your data) or Delete App and reinstall to fully clear the cache.
After clearing, Maps simply re-downloads tiles for areas you actually view next, so nothing important is lost.
Step 4: Reduce Future Storage Use
A few choices keep Google Maps lean long-term:
- Download offline maps only for trips, then delete them when you're back.
- Avoid downloading huge regions (entire states or countries) when a single city will do.
- Clear the cache every few months if you're a heavy navigator.
Google Maps is rarely the only app quietly consuming space, though. A review-first cleaner like Cleanor for Android (or Clenoir for iOS) scans on-device and surfaces large videos, screenshots, and duplicate photos, showing everything before you confirm a deletion. Nothing is removed without your approval.
What Clearing Maps Data Does and Doesn't Affect
It's worth knowing what's safe to remove so you don't lose anything you rely on.
- Cache: Map tiles, satellite imagery, and Street View thumbnails. Always safe to clear, Maps re-downloads them as you browse.
- Offline maps: Regions you intentionally downloaded. Deleting one means you'll need data (or a re-download) to navigate that area offline again.
- Clear storage (Android only): Resets the app completely, wiping offline maps, preferences, and local data. Use Clear cache instead unless you want a full reset.
Your saved places, labeled locations (Home, Work), lists, and Timeline are tied to your Google account, not local storage, so none of the cleanup above touches them. They reappear automatically because they live on Google's servers.
That's the reassuring part: aggressive cache clearing costs you nothing permanent, only a brief reload of tiles the next time you open the map.
Keep Your Phone Storage Healthy
Reducing Google Maps storage is one piece of a bigger picture. If your phone is generally tight on space, work through the heavy hitters: photos, videos, and other app caches.
For a structured routine, see the clean up phone storage hub, and if you're on iOS, the free up iPhone space hub and storage cleanup FAQ cover the rest. With unused offline maps deleted and the cache cleared, Google Maps should drop back to a reasonable size, and navigate just as well.
Want the fast version? Cleanor for iPhone scans on-device — nothing uploaded — and surfaces your largest videos, duplicate photos, and heavy caches in one pass. For the full routine, see the free up phone storage guide.
FAQ
What uses the most storage in Google Maps?
Two things drive the footprint: offline maps you downloaded, which can be hundreds of megabytes each for a single city, and the cache of map tiles, satellite imagery, Street View, and search data. If the total is large, offline maps are usually the bigger chunk and the easiest to manage directly inside the app.
How do I delete offline maps in Google Maps?
Open Google Maps, tap your profile picture in the top-right, tap Offline maps, then tap the three dots next to any region you no longer need and choose Delete. A downloaded map also auto-expires after about a year unless refreshed, so old ones may be lingering uselessly.
Will clearing Google Maps data delete my saved places?
No. Your saved places, labeled locations like Home and Work, lists, and Timeline are tied to your Google account, not local storage, so clearing the cache doesn't touch them and they reappear automatically. Just avoid the Android-only Clear storage option, which resets the app completely and wipes offline maps and preferences.
