It is a question without a meaningful answer. How about "a little larger than the surface of the Earth, most of the time"?
Ozone is found out into the exosphere, and all the way down to the surface of the Earth.
The ozone layer's altitude varies whether it is being measured over the poles or the equator. It is established by artificial limits, which gives it a top and bottom side. So this increases its surface area. And when it is late winter / early spring at a pole, a "hole" forms, which is below that threshold ozone value, so the area gets smaller.
The layer that affects the earth's surface is ozone. Ozone is a layer of importance.
There is a thin layer of ozone that covers entire surface. It is called ozone layer and protect us too.
The ozone layer is located in the stratosphere, extending from about 10 to 50 kilometers above Earth's surface. It covers the entire Earth and varies in thickness, with an average area of about 25 million square kilometers.
The hole in ozone layer is the thinning of ozone layer. It causes the harmful UV radiations of the sun to enter the earth's surface.
Ozone is continually made by the Sun. Ozone made at Earth's surface does not survive to reach the ozone layer.
See "In what layer of the atmosphere do you find the ozone layer?"
Stratosphere contains the ozone layer. It is present as a pool of ozone molecules.
The ozone layer is 12 - 15 km above the earths surface
The ozone layer is spread all over. It is over the whole earth.
When a meteor hits the ozone layer, it can cause localized heating and disruption of the ozone molecules. This can lead to a temporary thinning of the ozone layer in that specific area, which may allow more harmful UV radiation to reach the Earth's surface. Over time, the ozone layer can repair itself and return to its normal state.
The ozone layer shields the planet surface from harmful radiation from the sun. The less the ozone layer, the more the risk of skin cancer.
The ozone layer acts a protective shield on the surface of earth. This layer blocks out the harmful Uv radiations emitted from the surface of the sun.
