Human is too small to see at this scale and is marked with ▲.

Everything is drawn to the same scale, standing on the same ground line. Silhouettes are simplified outlines scaled to the measured dimension. A faded outline shows the top of a size range.

Zoom out from an average adult to the Burj Khalifa

The Burj Khalifa is too big to show next to an average adult in one picture, so here it is in 3 steps. Each step is drawn to its own scale and zooms out from the step before.

  1. Step 1 of 3 Human → Megalodon

    A megalodon is about 8.6–15 times as long as an average adult is tall.

    Step 1: Human and Megalodon at the same scale.

  2. Step 2 of 3 Megalodon → Great Pyramid of Giza

    The Great Pyramid of Giza is about 5.6–9.1 times as tall as a megalodon is long.

  3. Step 3 of 3 Great Pyramid of Giza → Burj Khalifa

    The Burj Khalifa is about 6 times as tall as the Great Pyramid of Giza.

About the Burj Khalifa

Burj Khalifa in Dubai, United Arab Emirates, completed in 2010, is the world's tallest building. CTBUH measures it at 828 m to its architectural top, which includes the spire, and 829.8 m to its very tip. It has 163 floors above ground, but the highest occupied floor is at 585.4 m, far below the top of the spire.

  • Burj Khalifa has 163 floors above ground and 1 below ground. [1]
  • It was completed in 2010. [1]
  • Its observatory is 555.7 m above the ground. [1]
  • Guinness World Records lists it as the tallest building, at 828 m (2,716 ft 6 in). [2]

How many fit?

  • ≈ 490 × Human · height lined up end to end match the Burj Khalifa · height (architectural)
  • ≈ 4.3 × Gateway Arch · maximum height lined up end to end match the Burj Khalifa · height (architectural)

Counts divide one sourced figure by another. "End to end" uses each object's main measurement; weight and volume rows appear only when both figures are sourced.

How it compares

  • 490× The Burj Khalifa is about 490 times as tall as an average adult. See side by side
  • 4.3× The Burj Khalifa is about 4.3 times as tall as the Gateway Arch. See side by side
  • 3.1× The Burj Khalifa is about 3.1 times as tall as the Titanic is long. See side by side
  • 2.1× The Burj Khalifa is about 2.1 times as tall as a container ship is long. See side by side
  • 1.5× The Burj Khalifa is about 1.5 times as tall as One World Trade Center. See side by side
  • 1/3.3 The Golden Gate Bridge is about 3.3 times as long as the Burj Khalifa is tall. See side by side

Factors compare the height (architectural) of the Burj Khalifa with each object’s own main measurement (height for a human). Where a size varies, the factor is given as a range.

Notes on these figures

  • The commonly quoted 828 m is CTBUH's height to the architectural top, which includes the spire; it is not the height to the tip. CTBUH gives 829.8 m to the tip. The task brief called 828 m the 'to tip' height, which is not correct.
  • Guinness World Records independently gives 828 m (2,716 ft 6 in), which matches CTBUH's architectural height.
  • The official site burjkhalifa.ae returned HTTP 403, both live and through the Internet Archive, so no figures were read from it.
