Jul 28, 2024 · How to use our distance to horizon calculator. Our tool implements a simple formula to calculate the distance to the horizon from a height. The only required input is the height of the observer. Try it with your height to check the distance of your horizon at sea level.
For an observer atop Mount Everest (8,848 metres (29,029 ft) in altitude), the horizon is at a distance of 336 kilometres (209 mi). For an observer aboard a commercial passenger plane flying at a typical altitude of 35,000 feet (11,000 m), the horizon is at a distance of 369 kilometres (229 mi).
Jan 26, 2024 · From the International Space Station in orbit, at a height of 420 km, the horizon is more than 2,300 km away; if you were to gaze out of a window, the entire U.S. Eastern Seaboard would be...

The distance to the horizon depends almost completely on the height above sea-level that the observer is looking from.
Knowing this number is extremely useful and often necessary when navigating over the ocean or going on a hike, though just being curious is reason enough! There are also a few other factors that you might have to consider depending on where you are in the world and the time at which you are viewing, such as temperature and weather conditions. Once you have all the measures you need, you can quickly get the calculation and know the exact distance you are from the horizon.
Measure your "height of eye."
Measure the length between the ground and your eyes in meters or feet. One way to calculate this is to measure the distance between your eyes and the top of your head.
this value from your total height and what will be left is the distance between your eyes and the surface you're standing on. If you are standing exactly at sea level, with the bottom of your feet level with the water, this is the only measurement you'll need.
Add your "local elevation" if you're standing on a raised surface, such as a hill, building or boat.
How many meters or feet above the true horizon are you standing? 1 meter? 4,000 feet? Add that number to your height of eye (in the same units, of course).
by 13m if you took the measurement in meters, or multiply by 1.
Calculate the actual distance you'd have to traverse to get to the horizon by using the following formula.
d = R * arccos (R/ (R + h)), where
• d = distance to horizon
• R = radius of the Earth
• h = height of eye
Increase R by 20% to compensate for the distorting refraction of light rays and to arrive at a more accurate measurement.
Assume a flat plane or the ocean.
This method is a simpler version of the first set of instructions presented in this article, and applies only in feet and miles.
Solve for the distance in miles by plugging in your height of eye in feet (h) into the formula.
The formula you will be using is d = 1.2246* SQRT (h).
Derive the formula from the Pythagorean theorem.
Solving for h (making the assumption that R>>h and expressing the radius of the earth in miles, approx. 3959) yields the expression:
Jan 15, 2009 · The horizon is then 1,006,344 km away, which is just about (but not quite) the Earth’s radius plus the observer’s distance over the surface. They are seeing almost — but not quite — half the Earth all at once.
Where is the horizon? For a man of 1.80 meters located at the edge of the sea, the horizon is approximately 4789 meters, only. How to calculate the distance to the horizon? Next figure at right, we will take as the distance of the radius of the Earth the mean radius 6 371 km.
