How Many Floors in the Empire State Building: The 102-Story Count and Why Your Elevator Button Says Otherwise

The Empire State Building has 102 floors, counted from the ground-level Fifth Avenue lobby to the top of the 102nd-story observation deck. That's the number the building's own operator, Empire State Realty Trust, publishes, and it's the figure the skyscraper has carried since it opened on May 1, 1931. What trips people up is everything downstream of that number: the buttons in the elevator cabs, the difference between "floors" and "stories," and the fact that a big chunk of the building's height isn't rentable office space at all. If you've ever ridden to the 86th-floor observatory and wondered why the panel skipped a bunch of numbers, you're in the right place.

The Official 102-Story Count and Who Publishes It

The 102 figure comes from Empire State Realty Trust, the real estate investment trust that owns and manages the building, and it appears in the company's own fact sheets and in the building's visitor materials. That's the authority to cite if you're settling an argument, not a blog or a trivia site. The count runs from the ground-floor lobby up through the 102nd level, which sits at the base of the mast rather than at the top of it.

Here's the part most people miss: the building is 102 stories but 103 "floors" in some older counts, because the original design included a flat roof deck above the 102nd floor that was sometimes tallied separately. Modern official material settles on 102. If you see 103 in a vintage source, that's why, and it isn't a contradiction so much as a change in how the roof was labeled.

The building's height figures help you place the floor count in context. According to the Empire State Building's own published specs, the structure rises 1,250 feet to the 102nd floor and 1,454 feet to the tip of the antenna. The roof height at the 102nd floor is 1,250 feet; the observation deck on 86 is at 1,050 feet. Those numbers come from the operator and are the ones to use.

One more anchor: when the building opened in 1931, it was the tallest in the world at 1,250 feet to the roof, a title it held until the World Trade Center's North Tower topped out in December 1970. The floor count hasn't changed since opening. The tenants have, the observatory has, the lobby has, but the steel skeleton is the same 102 levels it always was.

Why the Elevator Buttons Don't Go to 102

Ride the passenger elevators in the office core and you'll notice the buttons don't run in a clean sequence to 102. That's not a malfunction. The building's elevator system serves the office floors in zones, and the upper observation levels have their own dedicated lifts, so the cab you're in simply doesn't stop at every numbered floor.

The observatory access is the clearest example. To reach the 86th-floor deck, visitors take a dedicated elevator from the ground-floor observatory entrance; to continue to the 102nd floor, they transfer to a separate lift for the final 16 stories. That second lift is small and the ride is short, but it's the only way up to the top deck, and it explains why the 102nd floor feels like a different building entirely.

The office elevator banks work on the same zoned logic. A cab serving the lower floors won't have buttons for the high-rise floors, and vice versa. If you're visiting for business, check your tenant's suite number against the building directory rather than assuming the button will be there. If you're visiting for the view, follow the observatory signage and don't try to ride the office elevators up.

Failure case worth knowing: the 102nd-floor deck is open-air and exposed, and it closes in high winds or bad weather while the 86th-floor deck stays open. If your heart is set on the top deck, check the observatory's status before you buy the upgrade, because the ticket desk won't always warn you before you're already inside.

Floors vs. Stories vs. Levels: The Vocabulary That Causes Arguments

The words "floor," "story," and "level" get used interchangeably in casual conversation, and that's where a lot of the confusion starts. In building parlance, a story is the space between one floor surface and the next, and a floor is the surface itself. In a 102-story building, you have 102 floor surfaces you can stand on, which is why the count and the story count match here.

Ground floor vs. first floor is the other trap. In the U.S., the ground floor is the first floor, so the lobby is floor 1 and the count runs 1 through 102. In much of Europe and Asia, the ground floor is floor 0 and the first floor is what Americans call the second, which would make the same building "103" in a numbering scheme that starts at zero. The Empire State Building uses the American convention, so 102 floors means floors numbered 1 to 102.

Then there's "mezzanine" and "concourse" language. The building has a lower concourse level tied to the Fifth Avenue retail and transit access, and it's not counted in the 102. If someone tells you the building has "more than 102 floors because of the basement," they're mixing up stories above grade with total levels including below-grade space. The official 102 counts above-ground stories.

What Actually Sits on Floors 1 Through 102

The building isn't 102 identical office floors. The program breaks into distinct zones, and knowing them explains a lot of the odd numbering. Floors 1 through roughly 5 are lobby, retail, and building services. The office tower runs from the lower floors up through the 80s, with the highest office tenancy in the low-to-mid 80s.

Above the office stack, the 86th floor holds the main outdoor observation deck, the one with the iconic wraparound terrace. The 102nd floor holds the second, smaller observation deck, accessed by the dedicated lift. Between 86 and 102 sit mechanical floors, elevator machine rooms, and the building's broadcasting and antenna infrastructure, which is why those levels have no tenant space and no public access.

The antenna and broadcast equipment matter to the floor count because they sit above the 102nd floor on the mast, and the mast itself isn't a floor. That's the single most common source of "wait, isn't it taller than 102 floors?" confusion. The 1,454-foot height includes the antenna; the 102 floors stop at the 1,250-foot roof line.

How the 102 Floors Compare to Other Famous Towers

Putting the Empire State Building's 102 floors next to other landmarks makes the number easier to hold onto. The comparison below uses each building's own published floor counts, and the point is to show that floor count and height don't track neatly, because floor-to-floor heights vary enormously between office towers and residential or mixed-use towers.

The Chrysler Building comparison is the useful one for New Yorkers: it's 25 floors shorter than the Empire State Building but only about 200 feet shorter to the tip, because its crown and spire do a lot of the height work. Taipei 101 is the closest floor-count match at 101, and it's taller to the tip despite one fewer floor, which shows how much floor-to-floor height varies between a 1930s office tower and a 2000s mixed-use tower.

Burj Khalifa's 163 floors is the number people cite when they want to make the Empire State Building sound small, and it's a fair comparison in floor count but a strange one in historical terms. The Empire State Building was the tallest in the world for 40 years; Burj Khalifa has held the title since 2010.

The Construction Math Behind 102 Floors in 410 Days

The schedule is the part that still surprises people. According to the building's own history and contemporary accounts, the steel skeleton rose at an average of about four and a half floors per week, and the building topped out in 410 days of construction. That's a floor roughly every four days, which sounds impossible until you remember the design was repetitive and the crews worked in coordinated trades on a pre-fabricated steel frame.

Run the arithmetic: 102 floors over 410 days is about one floor every four days, and at the peak the crews were erecting steel at a rate of about four and a half stories a week. That pace was possible because the steel was fabricated off-site and delivered in sequence, and because the building's footprint was relatively compact for its height, which kept the crane and hoisting logistics manageable.

The 1931 opening came in the middle of the Great Depression, and the building famously struggled to fill its office space for years, earning it the nickname "the Empty State Building." That's a reminder that floor count and occupancy are different things. The 102 floors existed from opening day; the tenants took a while to arrive.

Does the 102nd Floor Mean You Can Visit 102 Floors?

No, and this is the practical answer most visitors need. You can visit two observation levels, the 86th-floor outdoor deck and the 102nd-floor top deck, and you can access the ground-floor lobby and the retail concourse. The rest of the building's floors are private office space, mechanical space, or broadcast infrastructure, and there is no public tour that walks you through 102 floors.

The observatory experience is two tickets in one journey: the main deck on 86 and the top deck on 102, connected by the dedicated lift. The 86th floor is the larger, open-air deck with the famous views south toward the Financial District and north toward Midtown; the 102nd floor is a smaller, glassed-in space with a tighter view and a shorter stay. If you only have time for one, the 86th floor is the one most visitors mean when they say "the Empire State Building observation deck."

Edge case: the 102nd-floor deck has limited capacity, and the lift is small, so on busy days the line for the top deck can be longer than the line for the main deck. If you're short on time, buy the main-deck ticket and skip the upgrade; if you want the bragging rights, budget extra time for the second lift.

The Antenna, the Mast, and Why the Height Confuses the Floor Count

The antenna and mast above the 102nd floor add about 204 feet to the building's total height, bringing it from 1,250 feet at the 102nd-floor roof to 1,454 feet at the tip. That antenna is broadcasting infrastructure, not occupiable floor space, and it's the reason the building's total height and its floor count don't scale together the way people expect.

The original 1931 design included a mooring mast for dirigibles at the top, and the 102nd floor sits at the base of that mast. The airship mooring idea never worked in practice, but the mast stayed, and it's why the top of the building has the distinctive stepped profile that shows up in every skyline photo. The 102nd-floor deck is at the base of that mast, which is why the view from up there feels like you're standing on the roof of the world rather than in a room.

If you're doing a height-to-floor calculation for a school project or a trivia answer, use 1,250 feet for the 102 floors and 1,454 feet for the full structure, and be explicit about which one you mean. Mixing them is the most common error in write-ups about the building.

Five Questions People Get Wrong About the Floor Count

The misconceptions cluster around a few predictable points, and clearing them up is faster than restating the whole history. Here are the ones that come up most often, each with the correction.

The first is that the building has 103 floors because of the roof deck. It doesn't; the official count is 102, and the roof deck above 102 is part of the 102nd level's structure, not a separate story. The second is that the 102nd floor is the highest occupiable space; it's the highest public observation space, but the antenna and broadcast equipment sit above it, and the mast isn't a floor.

The third is that the building was always 102 floors. It was, from opening day, though some early sources counted the roof separately and arrived at 103. The fourth is that the floor count and the height scale together across buildings; they don't, as the comparison table above shows. The fifth is that you can tour all 102 floors; you can't, and the two observation decks are the extent of public access.

FAQ

Is the Empire State Building 102 or 103 floors?

The official count is 102 floors, published by building owner Empire State Realty Trust, counted from the ground-floor lobby to the 102nd-story observation deck. Some vintage sources say 103 because they tallied the roof deck above the 102nd floor as a separate level, but modern official material settles on 102. If you're answering a trivia question, 102 is the number to give.

How many floors can you actually visit?

You can access three public areas: the ground-floor lobby, the 86th-floor outdoor observation deck, and the 102nd-floor top deck, plus the retail concourse. The other 99 floors are private office space, mechanical rooms, or broadcast infrastructure with no public access. The two observation decks are connected by a dedicated elevator that holds a small number of passengers, so budget extra time for the transfer.

How long did it take to build 102 floors?

The building topped out in 410 days of construction, which works out to roughly one floor every four days across 102 floors. Crews erected steel at an average of about four and a half stories per week at peak pace, according to the building's own construction history. The formal opening came on May 1, 1931, in the middle of the Great Depression.

How does the floor count compare to One World Trade Center?

One World Trade Center has 94 floors but rises 1,776 feet to its tip, taller than the Empire State Building's 1,454-foot antenna tip, because its floor-to-floor heights and spire are proportioned differently. The Empire State Building's 102 floors sit under a 1,250-foot roof line. Floor count and total height are separate measurements, which is why the two buildings rank differently depending on which number you use.

Why doesn't the elevator go to every floor?

The building's elevators are zoned, with separate banks serving low-rise, mid-rise, and high-rise office floors, and dedicated lifts for the observation decks. A single cab doesn't stop at all 102 floors because the zoning keeps wait times down and matches car capacity to tenant demand. If your destination button isn't in the cab, you're in the wrong elevator bank, not in a broken building.

What's the highest floor you can stand on?

The 102nd-floor observation deck is the highest point the public can stand, at 1,250 feet. The antenna and broadcast equipment above it reach 1,454 feet but aren't occupiable and aren't a floor. If you want the highest public vantage point in the building, the 102nd-floor deck is it, and it's reached by a separate small elevator from the 86th floor.

Did the floor count ever change?

No. The steel skeleton has been 102 stories since it opened in 1931, though the tenants, the lobby, and the observatory experience have all been renovated since. The confusion comes from labeling changes, not construction: early counts sometimes separated the roof deck into its own number. The building's official floor count has been 102 throughout its history.

Is the 102nd floor worth the upgrade over the 86th floor?

It depends on what you want. The 102nd floor is smaller, glassed in, and higher, with a tighter view and a shorter typical stay; the 86th floor is larger, open-air, and the deck most visitors picture when they think of the building. If you're short on time or traveling with kids, the main deck is the better value. If you want the top-of-the-building bragging rights, the upgrade is a short second elevator ride.
