The largest structure in the world is a matter of interpretation and can depend on different criteria such as size, volume, mass, or height. Here are some of the largest structures in the world based on different measures:
By volume:
The Great Barrier Reef in Australia is the largest structure in the world by volume. It is composed of over 2,900 individual reefs and 900 islands, covering an area of over 344,000 square kilometers.
By surface area:
The largest structure by surface area is the Great Wall of China, which stretches for over 21,000 kilometers.
By height:
The tallest structure in the world is the Burj Khalifa skyscraper in Dubai, which stands at 828 meters tall.
By mass:
The Great Pyramid of Giza in Egypt is the largest structure by mass, weighing approximately 6 million tons.
By length:
The longest man-made structure is the South-North Water Transfer Project in China, which is a series of canals, tunnels, and pipelines stretching over 1,400 kilometers to transfer water from the south to the drier north.
The largest structure by volume
The largest structure by volume is the Great Barrier Reef, located off the coast of Australia. The Great Barrier Reef is the world's largest coral reef system, composed of over 2,900 individual reefs and 900 islands, covering an area of over 344,000 square kilometers.
The reef is estimated to have a volume of around 2,900 cubic kilometers, which is more than 10 times the volume of the Grand Canyon in the United States. The Great Barrier Reef is home to thousands of species of marine life, making it one of the most biodiverse ecosystems on the planet. It is also a popular tourist destination, attracting millions of visitors every year.
The largest Structure by surface area.
The largest structure by surface area is the Great Wall of China, which is a series of fortifications that were built along the northern borders of China to protect against invasions. The Great Wall is one of the longest walls in the world, stretching over 21,000 kilometers across China.
The exact surface area of the Great Wall is difficult to determine, as it is not a single continuous structure and is composed of various sections that were built over different periods. However, it is estimated that the total surface area of the Great Wall is around 43,000 square kilometers.
The Great Wall is a UNESCO World Heritage site and one of the most popular tourist attractions in China, with millions of visitors each year.
Largest structure by height.
The tallest structure in the world is currently the Burj Khalifa skyscraper located in Dubai, United Arab Emirates. The Burj Khalifa stands at a height of 828 meters (2,716 feet) and has more than 160 floors.
The Burj Khalifa was completed in 2010 and was designed by Skidmore, Owings & Merrill. It is primarily used for commercial and residential purposes and includes a hotel, residential apartments, and office spaces. The building has several observation decks that offer panoramic views of Dubai and the surrounding area.
The Burj Khalifa broke numerous records upon its completion, including the title of the tallest freestanding structure in the world, the highest number of stories in a building, and the highest occupied floor in the world.

The largest structure by Mass.
The largest structure by mass is the Great Pyramid of Giza, located in Egypt. The Great Pyramid of Giza was built as a tomb for Pharaoh Khufu and is the largest of the three pyramids in the Giza pyramid complex. It is estimated to weigh approximately 6 million tons.
The Great Pyramid was constructed using over 2 million stone blocks, each weighing an average of 2.5 tons. The blocks were quarried and transported from nearby sites using a system of ramps and pulleys. The Great Pyramid is one of the most recognizable landmarks in the world and has been a popular tourist destination for thousands of years.
Despite being over 4,500 years old, the Great Pyramid of Giza remains one of the most impressive engineering feats in history and a testament to the ancient Egyptians' advanced knowledge of architecture and mathematics.
