Random Coordinates Generator
Generate random latitude and longitude points — worldwide, by hemisphere, or inside your own box.
Press the button and this generator hands you a random point on Earth: a latitude and a longitude, rounded to six decimal places, each with a link that opens the spot on OpenStreetMap. Draw one point for a geography prompt or a “where in the world” game, or up to twenty at once for test data, map work and sampling exercises. You can draw from the whole planet, from the northern or southern hemisphere only, or from a box of your own — a country, a state, a stretch of coastline — by typing its edge coordinates.
Draw random points on Earth. Worldwide points are uniform over the sphere, so they do not cluster at the poles — and since most of the planet is ocean, most of them land in water. That is the honest draw.
Wondering what time it is at a point you drew? Check the World Clock. For plain random numbers instead of places, use the Random Number Generator.
Quick answers
How are the random coordinates generated?
For worldwide draws, points are picked uniformly over the surface of the sphere: longitude is uniform between −180 and 180, and latitude is taken from an arcsine transform of a uniform cryptographic draw, so equal areas of the planet have equal chances.
The transform is the whole trick. Without it — latitude drawn evenly between −90 and 90 — points would cluster towards the poles, because a degree of latitude near a pole covers far less surface than a degree at the equator. With it, the average absolute latitude of a large sample lands near 32.7 degrees, exactly what surface-uniform sampling predicts.
Why do most random coordinates land in the ocean?
Because most of Earth is ocean — roughly 71% of the surface. A fair worldwide draw lands at sea about seven times in ten, and the Pacific alone, the largest ocean, takes a large share of those.
It can feel like a bug when five points in a row are water, but it is the honest result of sampling the planet by area. If you need land points, shrink the draw: pick a hemisphere to halve the map, or draw a custom box around the region you care about and every point will fall inside it.
What does the custom box mode do differently?
Custom mode draws latitude evenly between your minimum and maximum latitude, and longitude evenly between your minimum and maximum longitude — uniform inside the box, stated plainly, with no sphere correction.
For the small areas custom boxes are usually drawn around — a city, a county, a small country — the sphere correction would change almost nothing, and plain uniform-in-box is what testers and map tools generally expect. The worldwide and hemisphere modes are the ones where the geometry matters, and those use the sphere-uniform method.
How to use
- Choose a region: the whole world, the northern hemisphere, the southern hemisphere, or Custom to draw inside your own bounds.
- If you chose Custom, type the minimum and maximum latitude (−90 to 90) and longitude (−180 to 180) for the box.
- Choose how many points to generate, from 1 to 20, and press Generate coordinates.
- Open any point on OpenStreetMap with its View link, or use Copy all to take the whole list as text.
About this tool
The worldwide draw is done the way that is actually fair to the planet, and the difference is worth understanding. Earth is a sphere, and lines of longitude bunch together near the poles, so picking a latitude evenly between −90 and 90 piles points up around the poles and thins them out at the equator. This tool instead picks points uniformly over the sphere’s surface — latitude comes from an arcsine transform of a uniform draw — so every square kilometre of the planet’s surface has the same chance of being picked, pole to equator. The randomness itself comes from the browser’s cryptographic source, with rejection sampling on top.
Set your expectations before you draw: most of Earth is ocean. About 71% of the surface is water, so most worldwide points land at sea — the middle of the Pacific comes up a lot, and Antarctica and the Sahara account for a good share of the land hits. That is not the tool being unhelpful; that is what an honest, surface-uniform draw of this planet looks like. If you need points on land in a particular region, the custom box is the practical answer — draw a box around the area and the points will fall evenly inside it. Note that box mode is uniform within the box, in plain latitude and longitude, not corrected for the sphere, which is the right behaviour for the small areas boxes are usually drawn around.
Everything runs in your browser. The points you generate are never uploaded, sent anywhere or saved, and the map links only open when you click them. If you want to know what time it is at the point you drew, the World Clock linked below is a reasonable next stop; if you just want another kind of random, the Random Number Generator is there too.
Regions and how each one is drawn
| Region | How points are drawn |
|---|---|
| Whole world | Uniform over the sphere: latitude from an arcsine transform, longitude uniform −180 to 180 |
| Northern hemisphere | Sphere-uniform, latitudes 0 to 90 |
| Southern hemisphere | Sphere-uniform, latitudes −90 to 0 |
| Custom box | Uniform in latitude and longitude inside your bounds, no sphere correction |
Frequently asked questions
Are random coordinates more likely near the poles?
Not from this tool. A naive generator that picks latitude evenly does cluster points near the poles. This one uses an arcsine transform so the draw is uniform over the sphere’s surface — each square kilometre, polar or equatorial, has the same chance. You can check the signature yourself: over a few hundred worldwide points, the average absolute latitude sits near 32.7 degrees, not the 45 degrees a naive draw would give.
How precise are the coordinates?
Six decimal places, which is roughly 11 centimetres at the equator — far more precision than a random point needs, but it is the convention mapping tools expect, and it keeps copied coordinates unambiguous. The map link opens at zoom level 5 so you see the region first rather than a pinpoint pretending to be exact.
Can a generated point be somewhere I should not go?
Yes, easily — oceans, private land, military or restricted areas, the middle of a motorway. The point is a pair of numbers, not permission or a route. Read the note above the tool, and always check access and conditions before travelling anywhere a random draw suggests.
What are valid latitudes and longitudes?
Latitude runs from −90 (the South Pole) through 0 (the equator) to 90 (the North Pole). Longitude runs from −180 to 180, measured east and west of the prime meridian through Greenwich. In custom mode the tool swaps the bounds for you if you type a minimum larger than its maximum.
Why does the map link open OpenStreetMap?
It is a public map that needs no account or key, and the link format is simple and stable: the coordinates are placed in the link itself, so nothing is sent anywhere until you choose to click. No map is loaded inside this page.
Are my generated points stored anywhere?
No. The draw runs entirely in your browser and the list exists only in this tab. The only way a point leaves the page is if you click its map link or copy the list yourself.
