What is my elevation?: elevation finder and profile map

Find your elevation above sea level, or the height of any address, mountain or point you click on the map, in metres and feet. Draw a walk, ride or road to see its elevation profile, the total climb and descent, the highest and lowest points and the steepest slope. Works worldwide; free, no signup.

Elevation of any point, or along a route

Click anywhere on the map to get its height above sea level.

Heights from the Terrain Tiles open dataset on AWS (Mapzen), which combines SRTM, GMTED, ETOPO1, the US National Elevation Dataset and other sources (full attribution), read on your device. Pixels are about 10 to 30 m across depending on the area, so sharp summits can read a little lower than their official height. The profile samples the straight lines between your points.

How to find the elevation of a place

  • Your own elevation: press “My elevation” and allow location.
  • Any place: search an address, town, postcode or mountain, or just click the map.
  • A route: switch to “Elevation profile”, click along the way, then show the profile.
  • Feet or metres: tick “Feet and miles” to switch every figure.

Elevation, altitude and height above sea level

Elevation is the height of the ground above mean sea level. Altitude usually means the height of something above the ground or the sea, such as an aircraft. Mean sea level is an average, set by each country’s survey (Ordnance Datum Newlyn in Great Britain, NAVD 88 in the United States), so official heights in different countries can differ by up to a metre or so.

GradientRise per 100 mFeels like
2–3%2–3 mA gentle slope; noticeable on a bike
5–8%5–8 mA steady climb on foot or by bike
10–15%10–15 mSteep; hard work on a bike
20%+20 m or moreVery steep; the steepest roads in the UK reach about 30%

Planning a long walk? The total climb matters more than the highest point. A common rule of thumb for hill walking, Naismith’s rule, allows an hour for every 5 km of distance plus an hour for every 600 m of climb. To check the weather and air before you go, see air quality and UV.

Frequently asked questions

What is my elevation right now?

Press "My elevation" and allow location access. The tool finds the height of the ground where you are, above mean sea level, in metres and feet. If your phone also reports a GPS altitude, both are shown so you can compare them.

Why is my phone's altitude different?

GPS measures height less precisely than position, often within 10 to 30 metres, and some phones report height above the mathematical ellipsoid rather than above sea level, which can differ by up to about 100 metres. Height from an elevation model, as here, is usually closer.

Why does a mountain show lower than its official height?

Each figure is the height of a map pixel 10 to 30 m across, from radar and survey models. A sharp summit is the very top of its pixel, so it can read lower: Ben Nevis, 1,345 m, shows about 1,320 m. For a peak's official height, use the national mapping agency.

How do I see the elevation along a route?

Choose "Elevation profile", click along the route on the map, then press "Show elevation profile". You get a height chart, the total climb and descent, the highest and lowest points marked on the map, and the steepest stretch.

Is my house at risk of flooding if it is low?

Height alone does not tell you. Flood risk depends on nearby rivers, the coast, drainage and defences. In England, check the official long-term flood risk service, and for current warnings use our flood warnings map.
