Modern and ancient pyramids come in many forms and sizes. To determine which is the largest pyramid one could compare their heights for example. Many big pyramids however come with a very large base but are not very tall. A better measure of size therefore is probably the volume of a pyramid. The volume of a pyramid can be calculated by the following formula: Length of base, width of base, height. So, with this formula it shouldn’t be too difficult to find the largest pyramids in the world. Unfortunately, it isn’t that easy. Many pyramids are not true smooth sided pyramids but stepped pyramids. Another problem is that some of the largest pyramids on earth are still not completely excavated.

The Great Pyramid of Khufu is the oldest and sole remnant of the Seven Wonders of the Ancient World. Over 2 million blocks of stone were used to construct the pyramid, during a 20-year period concluding around 2560 BC. The pyramid is 755 ft in length and an awe-inspiring 455 feet high. So in the end, after reviewing all the biggest pyramids the Great Pyramid of Khufu remains the largest pyramid ever built.

The Pyramid of Khafre is the second largest pyramid at Giza, after the Great Pyramid built by Khafre’s father Khufu. It appears to be slightly larger however as it is built at a higher elevation. The pyramid has a base length of 706 ft and originally rose to a height of 471 ft but is now 36 feet shorter. The most distinctive feature of Khafre’s Pyramid is the topmost layer of smooth stones that are the only remaining casing stones on a Giza Pyramid.

The Great Pyramid of Cholula in Mexico appears to be a natural hill topped by a Catholic church. This is the “Iglesia de Nuestra Señora de los Remedios” which was built by the Spanish in 1594 on the site of a pre-Hispanic temple. According to the Guinness Book of Records, this temple is in fact the largest pyramid ever constructed anywhere in the world, with a total volume estimated at over 5,820 million yd³. This is based on a size of 1476×1476 ft and a height of 217 ft. Closer examination of the site reveals a different volume, however. The complex consists of several structures built on top of each other, starting from the 3rd century BC until the 9th century AD. The base of the pyramid itself is ‘only 968 by 886 ft which gives a much smaller volume, although the Cholulu Pyramid is still the third largest pyramid ever built.

Built by Pharaoh Sneferu, the Red Pyramid is the world’s first successful attempt at constructing a true pyramid. The pyramid measures 722 ft and is 341 ft high. It was the largest pyramid in Egypt until the construction of the Giza pyramids. What really makes the Red Pyramid special today is the lack of crowds that plagues the Giza Plateau and the comparatively unregulated interior access.

The Bent Pyramid located at Dahshur was the second pyramid built by pharaoh Sneferu. Mysteriously, the Egyptian pyramid rises from the desert at an angle of 55 degrees and then suddenly changes to a more gradual angle of 43 degrees. One theory holds that due to the steepness of the original angle the weight to be added above the inner chambers and passageways became too large, forcing the builders to adopt a shallower angle. The base of the pyramid is 619 ft and the height is 332 ft.
