Check How Accurate Your Location Really Is

By Dan · Last updated September 2026

Every location tool draws a pin and states your coordinates to seven decimal places, whether the underlying fix was accurate to five metres or five kilometres. That precision is usually fake: your browser hands back an honest accuracy figure alongside your position, and most tools throw it away. This one doesn't. Click "Use My Location" and you'll get a pin, a circle sized to your browser's own accuracy figure, and coordinates rounded to match, not overstated. The circle is the real answer here, not the pin.

See why phone and laptop results differ before you click.

"Where am I" tools have existed for years, and almost all of them make the same mistake: they show a pin and a set of coordinates with no hint of how good the underlying fix actually was. A position accurate to three kilometres gets printed with the same seven-decimal confidence as one accurate to three metres. This tool reports what your browser actually knows, not more.

Your browser's geolocation service returns three things: a latitude, a longitude, and an accuracy figure in metres describing how sure it is. That third number is the one everyone else discards. Here, it decides how many decimal places your coordinates get shown with, how large the circle on the map is, and what plain-words accuracy statement you see - "accurate to about 15 metres" or "accurate to about 3 km", not a false-precision number dressed up to look more confident than it is.

Before you click: why browser location drifts

Phone versus laptop. A phone usually carries a GPS chip, which can place you to within a few metres outdoors by timing satellite signals - no internet connection even required for the position fix itself. A laptop almost never has a GPS chip, so its browser instead estimates your position from the wifi networks it can see nearby, a method that typically lands somewhere between tens and a few thousand metres of accuracy, and can be far worse with few networks in range. This tool infers which method likely produced your result from the accuracy figure alone (the browser doesn't report the method directly) and says so in plain words next to your result.

Why a website can think you're in the wrong town. Most sites never ask your browser for its GPS or wifi position at all - they guess from your IP address instead, which only reveals roughly where your internet connection is routed from. That can be a real city away from where you're actually sitting, especially on mobile data or certain VPN and satellite connections, which is why a streaming service, a search engine, or a weather site can confidently get your town wrong while a tool that requests your browser's actual location gets far closer. Two different methods, both casually called "my location", with very different accuracy.

What the circle means, and why a smaller one isn't always available. The circle is not decoration: it's the honest range your position could genuinely fall within, given what your device could measure. A smaller circle requires either a GPS chip doing its job outdoors, or enough nearby wifi networks for a tighter wifi-based estimate - neither of which any website, including this one, can improve from the outside. When the circle is large, that's the fix being honestly uncertain, not this tool failing.

How It Works

  1. Click "Use My Location" and allow the permission prompt - or click "Click on Map Instead" and pick a point yourself
  2. See your pin and accuracy circle, sized to what your browser actually reported
  3. Read the plain-words accuracy statement and the likely method (GPS, wifi, or a broader estimate)
  4. See the place name, looked up from your coordinates via OpenStreetMap - the one thing on this page sent anywhere

Frequently Asked Questions

Why does this tool show a circle instead of just a pin?

Your browser reports your position along with an accuracy figure in metres, which is an honest statement of how sure it is, not a guess this tool adds on top. Most location sites throw that number away and print a pin with coordinates to seven decimal places regardless of whether the fix was accurate to five metres or five kilometres. This tool draws the circle because the circle is the real answer: you are probably somewhere inside it, and the size of the circle is exactly how much this tool actually knows.

Why is my location more accurate on my phone than my laptop?

A phone usually has a GPS chip, which can place you to within a few metres outdoors by timing signals from satellites. A laptop almost never has one, so its browser instead estimates your position from nearby wifi networks it can see, a method that is typically accurate to tens or hundreds of metres rather than single-digit metres, and can be kilometres off if few networks are visible. The accuracy figure this tool shows reflects that difference directly: a small circle usually means GPS, a larger one usually means wifi.

Why does a website think I'm in the wrong town?

Most websites don't ask your browser for its GPS or wifi position at all; they guess from your IP address instead, which only reveals roughly where your internet connection is routed from, sometimes a real city away from where you actually are. That's why a streaming service or a search engine can place you in the wrong town while a tool that actually requests your browser's location, like this one, gets a far closer answer. IP-based location and browser geolocation are different methods with very different accuracy, even though both get called "my location".

Why did I get a very large accuracy circle?

A large circle means your browser could only produce a broad estimate: no GPS chip, few or no wifi networks nearby to triangulate from, or a network connection (like some VPNs and mobile carriers) that only narrows your position to a wide area. It isn't a fault in this tool, it's an honest report of a genuinely uncertain fix. A smaller circle usually requires either a GPS chip or a location with more visible wifi networks, neither of which a website can create for you.

What happens if I say no to the location permission prompt?

The tool tells you plainly that it can't find you without permission, and offers the alternative straight away: click anywhere on the map to check that point instead. A manually placed point has no accuracy circle, since it isn't a measurement with a margin of error, it's simply the spot you chose.

Is my location sent to your server?

No. The pin and the accuracy circle come entirely from your own browser and never leave it. The one exception is turning your coordinates into a place name ("near Springfield, IL"), which is sent to OpenStreetMap's Nominatim to look up, triggered only when you click Use My Location or the map, never automatically and never repeated. If that lookup fails, the pin and circle are unaffected. The Copy Link button puts your coordinates into the URL itself so the link shows the same result when opened, which is not the same as sending them to a server: nobody sees them unless you choose to share that link.

A Note on Expectations

This page will not rank for "where am i" any time soon. That's the highest-volume query in this space, the incumbents are entrenched, and this domain is young. That's fine: this tool exists to round out the site's set of locator tools, to be a natural link target from the postcode and ZIP tools, and to answer the specific questions people actually search when a location result looks wrong, like "why is my location wrong" or "how accurate is browser location", which are lower volume, far less contested, and answered badly by incumbents who are usually the ones being wrong. Judge it on that, not on the head term.
