Data usage
How much data does Google Maps use? Navigation uses surprisingly little
As a guideline, Google Maps uses about 5 to 20 MB per hour for navigation. Offline maps, satellite view, searches, and traffic information change usage.
In this guide
During ordinary navigation, Google Maps uses approximately 5 to 20 MB per hour as a HolySim guideline after the map area and route have loaded. Searches, satellite view, Street View, photos, and live traffic information can increase usage.
HolySim advice: download your map area over Wi-Fi before departure. Keep mobile data enabled for current traffic information, new searches, and route changes.
Navigation uses less data than video
A five-hour drive uses approximately 25 to 100 MB for the navigation session according to our guideline. Even with additional searches, this is usually much less than one hour of YouTube or TikTok.
For a two-week road trip with three hours of driving each day, you can reserve roughly 0.2 to 0.8 GB for active navigation. Add some margin for route planning, place photos, and map updates.
Google does not publish a fixed number of MB per hour. The Maps app adjusts downloads based on the area, zoom level, cache, and selected view. The range is therefore a HolySim planning estimate.
Which features use data?
GPS determines your position using satellite signals and is not the same as mobile internet. Google Maps uses data for activities including:
- loading map tiles and street names;
- calculating and recalculating routes;
- traffic congestion, closures, and alternative routes;
- searching for restaurants, fuel stations, and addresses;
- photos, reviews, and opening hours;
- Street View and satellite imagery;
- public transport departure times and shared mobility;
- live location sharing.
A blue position arrow can therefore work without data while a new map area remains blank because the map information is missing.
Standard map, satellite view, and Street View
The standard map uses the least data. Satellite view contains much more visual information and requires larger map tiles. Street View loads photographic imagery around the selected place and can use tens of MB even in a short session.
Use satellite view or Street View at home to recognize a hotel entrance, parking area, or the start of a walking route. Take a screenshot if helpful. Switch back to the standard map while traveling.
Photos and reviews of places are also heavier than the route itself. Search for restaurants over Wi-Fi if you want to browse extensively.
Download offline maps
In Google Maps, open your profile picture, select Offline maps, and then Select your own map. Move the frame over your travel area and download it over Wi-Fi.
Google confirms that an offline map can provide navigation when your connection is slow or unavailable, provided the entire driving route is inside the downloaded area.
The app shows how much storage the area requires before downloading. This can range from tens to hundreds of MB and may be more for large regions. Do not download it through your travel eSIM unless you consciously want to use that allowance.
What does not work fully offline?
Google lists clear limitations. Public transport, cycling, and walking routes are unavailable without a connection. Offline driving directions do not include traffic information or alternative routes.
New business information, current opening hours, reviews, and live location sharing also require the internet. An offline map is a strong foundation, not a complete copy of Google Maps.
Download the route and save crucial addresses as text or screenshots. If you travel outside the saved area, the app must load new map data or the display remains blank.
How much storage does an offline map need?
The size depends on the surface area and information density. A compact city is smaller than an entire country. Google Maps displays the expected download size before you confirm.
Offline maps expire and are updated. According to its help center, Google tries to automatically renew maps that expire within fifteen days over Wi-Fi. Check shortly before departure that the map is current.
If your phone has little storage, select only the route corridor and cities where you will stay. You do not need to download an entire continent for one coastal drive.
Navigation in the car
Start the route over Wi-Fi before departure when possible. The app can preload map sections and route details. Keep mobile data available for traffic jams and diversions.
Missing a turn may require recalculation. That generally works for driving routes inside the offline area; outside it, a connection is necessary. Download some space around your planned route.
When you use Android Auto or CarPlay, the data usually comes from the connected phone. A large car display does not automatically make the map much heavier, although additional searches and satellite view do.
Walking and public transport
For city walks, a screenshot of the final section is useful because offline walking directions are limited. Also save the name and address of your accommodation as local text.
Public transport planning itself usually uses little data, but live departure times and route changes must be retrieved. Reserve data for replanning during a delay.
GPS can be inaccurate in a medina, metro station, or between tall buildings. That is not a data problem. Wait for a better position and use landmarks.
Measure Google Maps data usage
Switch off Wi-Fi, note the data counter for Google Maps, and navigate for thirty to sixty minutes as you would on your trip. Check the difference afterward. Test the standard map and satellite view separately if you use both.
On iPhone, app usage is shown under Settings > Cellular. On Android, find Google Maps under App data usage. The counter may include background updates and earlier sessions, so select a clear measurement period.
A test on a familiar route may produce a lower result because map sections are already cached. Also test a new area, or leave the cache intact and add extra margin.
Google Maps in your data plan
For a normal holiday, Google Maps is rarely the largest expense. Reserve 0.5 to 1 GB for a trip with extensive route planning and navigation. Download large areas at home and add more if you frequently use Street View, photos, and satellite imagery.
Video and social feeds usually determine whether you need 5, 10, or 20 GB. Compare usage across apps and calculate your wider travel needs before choosing a plan.
Sources and editorial review
Features and offline limitations were checked in the official Google Maps Help. Google does not publish a fixed MB-per-hour table, so all usage ranges are HolySim guidelines. Area, cache, zoom level, view, search behavior, and updates change actual usage. Last substantively reviewed on July 15, 2026.
Frequently asked questions
How many MB does one hour of Google Maps use?
Allow approximately 5 to 20 MB per hour for ordinary navigation after the route and map area have loaded.
Does GPS work without mobile data?
Yes, GPS positioning can work. You still need stored map information to see that position usefully on a map.
Does Google Maps work completely offline?
No. Driving routes can work inside a downloaded area, but traffic, alternative routes, and public transport, cycling, and walking directions are limited offline.
Does satellite view use more data?
Yes. Satellite imagery and Street View are heavier than the standard map. Preferably use them over Wi-Fi.
Is 1 GB enough for Google Maps on holiday?
Usually more than enough for ordinary navigation, especially with offline maps. Frequent photos, Street View, satellite imagery, and new map downloads can increase usage.
