The basics

OS Maps works on all computers, tablets and smartphones which include an up-to-date browser that can run HTML 5, these include:  

  • Edge (current version)  

  • Chrome (latest release)  

  • Firefox (latest release)  

  • Android browser/Chrome for Android (current version)  

  • Safari on iOS and Mac (latest release)  

  • Chromium on Ubuntu (current stable build)  

Windows phone/tablet users may find that some touchscreen devices are inaccurate when doing route planning due to issues with the touch location detection.  

Aerial 3D map (Premium subscribers only): 

The speed and clarity of this map type may be impacted if you have an older computer, a computer without a graphics card or a lower-end mobile device. If this is the case, try closing any unnecessary programs and browser tabs to speed up the Aerial 3D map.  

The 'HD' option for Aerial and Aerial 3D will be enabled only if your device supports it.  

Recommended minimum for Aerial 3D: Core i5 2GHz, 4GB memory, Intel HD 5000 / Nvidia 720M / Radeon HD 8670M GPU  

High-resolution mapping and images can use quite a lot of data, so we recommend you use OS Maps on WiFi rather than 4G/5G connection.  

On phones and tables (Android and Apple) we recommend using the OS Maps app. The OS Maps app can be downloaded from the App or Play Stores.  

The OS Maps app is free to download. Log in using your existing OS Maps account. If you have a premium subscription it will cover both desktop/web and all your mobile devices.

By default, only waypoints with notes are shown in the waypoint list or printed on the route card.

The time estimates for walking will automatically allow for ascents using Naismith's Rule which adds 1 hour for each 600m of elevation gain (or 10 minutes per 100m). There is no adjustment for descents or difficult terrain such as mud or vegetation, therefore this is just an estimate.  

For cycling this is a simple speed x distance calculation, so adjust the speed to your average cycling pace and allow for climbs manually.  

Estimated times are available for walking, running and cycling only. 

To change the speed calculations,  

Select: account name (top right) > Preferences   

or  

Select: menu (☰ symbol) > My Preferences  

There, you can change the estimated speeds to your speeds for the type of terrain you normally cover, this should result in more accurate estimation.

Due to the way that elevation is calculated it works better across a route with more waypoints. When a route is plotted, the elevation profile is determined by calculating points on the terrain using predefined intervals on the length of that route line to get the overall ascent between the waypoints.  

If the route line is a segment consisting of two waypoints then the ascent will be calculated by taking the centre of that line between the two waypoints, which may not show the correct level of ascent, especially on steep terrain. When you add another waypoint in between then it will give you a more accurate value for the total ascent.

Menu (☰ symbol) > Routes > My Routes  

‘My Routes’ is a library where all your favourite & created routes are saved.

You must be logged into your relevant account if you are sharing to your social media. 

Users/recipients following a link will open OS Maps on Standard Map with the route in view (even if they are not currently registered or logged in). Premium subscribers will be able to switch to other map types.

GPX export is available to Premium subscribers only.  

Menu (☰ symbol) > Routes > My Routes  

Select your chosen route 

The route card will be on the left hand-side of the screen 

Select ‘Export GPX’ (icon found under the route description) 

Once you have created your GPX file it can be imported into almost any GPS device to follow the route. Please refer to your GPS manual and search for using or importing a GPX file.  

Your system may not recognise a GPX file and ask you to associate a program with it. The easiest is usually Notepad, but make sure when you save the GPX file the extension (the bit after the file name) is not change to .txt. or .xml as then it will not work properly. 

Garmin Connect 

OS Maps does not have the ability to use the Garmin Connect software to automatically move routes into a connected Garmin device. This is because Garmin Connect requires browser plugins, which most modern browsers will no longer allow. 

You can upload the GPX file manually or use the Garmin Basecamp software to transfer the file, and once Garmin make new software available, we will investigate adding it to OS Maps.

Yes. 

Menu (☰ symbol) > Routes > Import GPX  

Select 'Choose File' Select your chosen file then click ‘Save’  

Once route has been imported it will be saved in 'My Routes' 

You can modify/edit this route as normal.  

Imported GPX files do not use the timestamps from the file (if available) to calculate route estimated times, but instead calculate it based on the activity and your personal average speed settings (set in 'Preferences').

GPX files come in a wide range of versions. OS Maps can handle the most common versions but may not understand some formats.  

We have set a maximum size of 10MB. If your GPX file is larger than this reduce the size by splitting the route into multiple files or reduce the number of waypoints/waypoint information. Most GPS software packages can do this.  

Routes with over 1000 waypoints will be generalised to reduce the total waypoint count using the Douglas-Peucker algorithm, which removes unnecessary waypoints without changing the overall route.

If you believe there is a problem with any route published on OS Maps please contact our  Customer Service Centre providing the URL of the route concerned. 

We will investigate further and if we believe it is appropriate the route may be taken down in accordance with our Take Down Procedure described in Section 1.7 of the OS Maps Terms. 

Personalisation and options

Yes! This can be changed in your preferences. 

Select: My Account (top right) > My Preferences > Units of Measurement

Premium subscribers can print standard or Premium Topo maps (including routes) in A4and A3 portrait or landscape.  

There is no printing available for Aerial 3D.  

To print, first ensure your chosen area is visible on the screen, then select ‘Print' (towards the right-hand side on the white navigation bar across the top of the screen). 

The map area that falls within the highlighted box will be printed, to move this area click and drag the map.  

A print panel will appear on the left-hand side of the screen, here you can select and change your printing preferences. Zooming in, changing the paper size and/or page orientation will change the area covered by the print.  

Once you are happy with your print selection select the pink “Print” button found at the bottom of the left panel.   

The map will print the current type selected. To change your current map type, select the ‘Switch map style’ icon on the bottom right-hand side of the screen.   

When printing Premium Topo maps it will default to current scale, you can override this by choosing a different scale.

Explorer and Landranger maps are available for Premium users in Great Britain only. 

To print in Explorer or Landranger you will need to select the Premium Topo map. To change your current map type, select the ‘Switch map style’ icon on the bottom right-hand side of the screen. You can also zoom in/out on your chosen map type.  

Select ‘Print' (towards the right-hand side on the white navigation bar across the top of the screen). On the left-hand side menu, you can select your printing preferences including Explorer and Landranger. 

Explorer and Landranger maps are available for Premium users in Great Britain only. 

We have deliberately limited the maximum area you can print on the 1:25K or 1:50K maps so the detail is clearly visible. If your route will not fit on an A4 page, you can either print in A3 (if your printer allows and you have a premium subscription) or print the route on multiple sheets of paper.  

To print on multiple sheets of paper ensure your first chosen map area falls within the highlighted box, when happy select ‘print’. Then move on to your second chosen area, ensuring it falls within the highlighted box. Remember to create a small overlap with the previous map, when happy with your selection select ‘print’ then repeat, as necessary.  

This process will allow you to print large maps for long routes, but still use a scale that shows required detail.

Most print problems are caused by the print settings on your computer not matching the options set in OS Maps.  

After selecting the landscape option in OS Maps, we have found on some computers the print setting in the print dialog needs to be set in portrait mode (still selecting A4 or A3) 

You can test your print set up by using print preview or by printing in black and white before colour.

Please ensure your printer can print in A3 and has suitable paper to create the print.  

Ensure the print options are set to A3, and then use your computers print driver settings to adjust the print options, including selecting the correct tray with the A3 paper loaded.  

Every printer works slightly differently, and you may have to experiment to find a setup that works for you.  

Depending on your computer and browser settings you may need to use the 'Print using system dialog' option to be able to adjust the print driver settings on each print.  

Please ensure you are using the latest version of your chosen web browser.  

Always print using the print function in OS Maps, not the browser print function. 

My print only shows part of the map and leaves half the paper blank (A4)? 
Check the paper orientation on the print driver and change. Many printers will need to be on 'portrait' even for landscape prints  

The complete map is printed but is too small, with a large white border? 
Check the paper size setting in OS Maps matches the print driver setting  

The print covers the page, but only shows only part of the map? 
Check the paper size setting in OS Maps matches the print driver setting  

My printed map is split over two pages? 
Check paper orientation and size, and reduce print margins as far as possible in the print driver  

If your problem persists, try clearing your cookies and cache. Most web browsers clear your cookies and cache by: pressing Ctrl-Shift-Delete (Windows) or Command-Shift-Delete (Mac) and select 'cached files' or similar. 

The most common reason is that the browser print button is being used. Please ensure you always print using the print function in OS Maps, not the browser print function.  

Please also checked that you have not been automatically logged out after not using OS Maps for some time. Try saving your route to trigger the login screen or log out and back in if there are no changes to save.

OS Maps runs in your web browser, so any feature or app that allows you to print from your web browser will allow you to print your map.

Please read the about Cloudprint for Android or AirPrint for Applefor the official way to print from these devices (other suppliers also offer apps with additional features).  

For support with getting printing to work from your device please contact your device manufacturer.

The ‘find my location’ button can be found on the right-hand side of the map towards the bottom.  

Your browser’s location data is used to identify your current location. For this to work, your browser's location services must be enabled - most browsers will display a pop-up message or an icon in the address bar asking you to allow this.  

Location services are most accurate on devices with GPS, which includes smartphones and some tablets.  

For desktop computers the browser makes its best guess based on user information and IP address. However, depending on your computer this can vary in accuracy, often showing an approximate position within a few kilometres, or showing the location of your broadband provider.
