Size matters. At least, in the world of high-stakes civil engineering and oil-rich ego, it definitely does.
If you’re looking for a quick answer, here it is: the Burj Khalifa in Dubai is the tallest building in the world. It’s been sitting pretty at the top since 2010. It is 828 meters tall. That’s about 2,717 feet for those of us still stuck on the imperial system.
But honestly? Staying at the top for sixteen years is kind of a miracle in this industry. Usually, as soon as one guy finishes a glass-and-steel needle, someone else starts digging a hole for a bigger one. Right now, there is a literal race happening in the desert to see who can finally knock Dubai off its pedestal.
Burj Khalifa: The King That Won't Quit
You've probably seen the photos. It looks like a giant silver syringe piercing the clouds.
What most people don’t realize is that the Burj Khalifa isn't just tall; it’s basically its own ecosystem. It has 163 floors above ground. If you tried to walk up the stairs, you’d have to tackle 2,909 steps. Please don’t do that. The elevators are much better—they move at 10 meters per second, which is fast enough to make your ears pop like bubble wrap.
The design is actually inspired by a flower called the Spider Lily (Hymenocallis). It’s got this Y-shaped footprint that helps with structural integrity. But there’s a secret to its height that is a bit... well, controversial.

The "Vanity Height" Scandal
About 244 meters of the Burj Khalifa is "vanity height." Basically, the top part of the spire is just empty steel. It’s there so nobody else can beat the record easily. Without that spire, the building would be significantly shorter, though still a giant.
Engineers like Adrian Smith (the architect behind the Burj) had to figure out how to stop the building from swaying too much in the wind. The solution? Confuse the wind. The building’s "setbacks"—those terrace-looking steps on the way up—are shaped differently at every level. This breaks up the wind vortices so the tower doesn't wobble like a giant tuning fork.
The Contenders: Who Is Actually Trying to Beat It?
For a long time, everyone thought the Jeddah Tower in Saudi Arabia was a goner. It was supposed to be the first building to hit the 1-kilometer mark (1,000+ meters). Construction started in 2013, then it stopped in 2018. It sat there as a concrete stump for years.
But things changed recently.
As of January 2026, the Jeddah Tower is back in action. Reports from the site show that it has finally moved past the 80-floor mark. The Saudi Binladin Group is back on the job with a massive contract, and they are moving fast—adding new floors every few days. If they keep this pace, they might actually finish it by 2028.

Then there’s Kuwait. They have this plan for the Burj Mubarak Al Kabir. It’s supposed to be 1,001 meters tall—a cheeky nod to One Thousand and One Arabian Nights. But honestly, it’s mostly just a proposal on paper right now. While they’re working on the port nearby, the tower itself feels more like a "someday" project than a "right now" project.
The Global Top 5 (The Current Standings)
If you were to look at the skyline of the planet today, here is the leaderboard:
- Burj Khalifa (UAE) – 828m. Still the champ.
- Merdeka 118 (Malaysia) – 679m. A sleek, faceted tower in Kuala Lumpur that recently took the silver medal.
- Shanghai Tower (China) – 632m. It’s famous for that 120-degree twist that helps it survive typhoons.
- Makkah Royal Clock Tower (Saudi Arabia) – 601m. Huge, bulky, and has the world's largest clock face.
- Ping An Finance Center (China) – 599m. A stainless-steel beast in Shenzhen.
Why Do We Keep Building These Things?
It’s not for the office space.
Building something like the Burj Khalifa costs roughly $1.5 billion. Maintenance is a nightmare. To wash all the windows, it takes a crew about three to four months. By the time they finish the last window, the first one is dirty again.
It’s about "Brand Urbanism." Cities build these to put themselves on the map. Before the Burj, "Downtown Dubai" was mostly sand. Now, it's the most expensive real estate in the region. The building is a giant flagpole that says, "We are here, and we have more money than you."

Temperature Shifts
Here is a weird fact: it’s actually colder at the top of the tallest building in the world. There is about a 6 to 15-degree Celsius difference between the ground floor and the tip of the spire. If you’re standing at the base in 40°C heat, it might be a breezy 25°C at the very top.
What You Should Do If You Visit
If you’re actually going to Dubai to see the tallest building in the world, don't just buy the cheapest ticket.
- Book "At The Top Sky": The standard observation deck is on the 124th floor, but there’s a higher one on the 148th. It’s more expensive, but the crowds are thinner and the view is genuinely terrifying in a good way.
- Watch the Sunset Twice: This is a classic local trick. Watch the sunset from the ground, then take the high-speed elevator up to the top immediately. Because of the height, you’ll see the sun "set" a second time over the horizon.
- Check the Weather: If it’s a foggy morning, go up. You’ll be above the clouds, and it looks like a scene from Star Wars.
The Future of the Sky
The record is safe for 2026. The Burj Khalifa remains the tallest building in the world for now. But keep your eye on Saudi Arabia. The Jeddah Tower is growing again, and the race to 1,000 meters is officially back on.
For now, the best way to experience these megastructures is to see them in person. Photos don't really capture the scale; you need to stand at the base and crane your neck until it hurts.
If you're planning a trip to see these giants, start by checking the flight schedules to Dubai or Kuala Lumpur. Most of these observation decks require bookings weeks in advance, so don't leave your tickets to the last minute. If you want to see the "next" big thing, keep an eye on progress reports from Jeddah Economic City—that's where the next record will likely be broken.
