Ever stood against a doorframe with a tape measure and felt like the math just wasn't mathing? It happens. Honestly, most people think they know exactly how tall they are until they have to fill out a driver's license form or a medical chart that asks for height in a single unit. If you’re trying to figure out 5 foot 11 inches in inches, the quick answer is 71 inches.
But why does that specific number feel so much taller or shorter depending on who you ask?
Height is weird. It’s one of those things where a single inch can change your entire vibe. In the US, we’re stuck with the imperial system, which is basically a collection of historical accidents turned into math. 5'11" is that "almost there" height. It’s the gatekeeper to the 6-foot club, and because of that, it carries a lot of weight in everything from dating profiles to basketball scouting reports.
The Raw Math of 5 foot 11 inches in inches
Let's break it down without the fluff. You’ve got five feet. Each foot has 12 inches. $5 \times 12 = 60$. Then you add that extra 11. That gets you to 71.
Simple, right?
Well, sort of. While 71 inches is the mathematical reality, the way we perceive that measurement changes based on context. If you’re 71 inches tall, you’re technically in the 75th percentile for adult men in the United States according to the CDC’s National Center for Health Statistics. You are taller than the average guy (who sits around 5'9"), but you’re still looking up at the "true" tall guys. It’s a middle-ground measurement that often leads to "height inflation."

I’ve seen people who are clearly 5'10.5" claim 71 inches because it sounds more substantial. And then you have the guys who are actually 71 inches but claim 6 feet because, let's be real, it’s only one more inch. But in the world of data and manufacturing, that one inch is huge.
Where 71 Inches Actually Matters
Think about buying a car. Or a bed.
If you’re 5 foot 11 inches in inches, you are at the sweet spot for ergonomics. Most industrial designers at companies like Ford or IKEA use "the 50th percentile male" or "the 95th percentile male" as their North Star for design. At 71 inches, you fit into almost every standard cockpit, office chair, and shower stall without having to duck or stretch. You aren't "too tall" for the world, but you're tall enough to reach the top shelf at the grocery store.
Actually, let’s talk about clothing. Most "Regular" sized shirts are designed for a man who is roughly 5'9" to 6'0". If you are 71 inches, you are the goldilocks zone. You don't usually need a "Tall" size, but "Small" is definitely out of the question. Your wingspan—which usually roughly equals your height—means you’re probably rocking a 32 or 34-inch sleeve length.
The Psychology of the "Almost 6 Feet" Measurement
There is a strange social phenomenon surrounding 5 foot 11 inches in inches. In the world of online dating, studies—like those analyzed by data scientists from the former OKCupid blog—showed a massive "cliff" in desirability between 5'11" and 6'0".

It's silly. It's just one inch. 2.54 centimeters.
Yet, 71 inches is often viewed as "average plus" while 72 inches is "tall." This leads to a lot of people lying. If you see a guy who says he's 6 feet tall, there is a statistically high chance he is actually 71 inches. Professional sports do this too. The NBA is notorious for "height inflation." Players are often measured in their shoes, adding an extra inch or two to their official program height. A player listed at 6'1" is very likely 5'11" in their socks.
Why the Metric System is Just Easier
If we were in Europe or literally anywhere else, we’d just say 180.34 centimeters.
180 feels like a solid, round number. It doesn't have the "not quite 6 feet" baggage that 71 inches carries. When you convert 5 foot 11 inches in inches to centimeters, you realize just how precise the measurement is. One inch is exactly 2.54 cm. That’s a standard set by the International Yard and Pound Agreement of 1959. Before that, an inch varied slightly depending on whether you were in the UK or the US. Imagine that—your height literally changing just by crossing the Atlantic.
Measuring Yourself Correctly (The Stadiometer Method)
If you’re trying to settle a bet or fill out a medical form, don't just lean against a wall and guess. Most people measure themselves wrong. They use a floppy tape measure or they don't keep their head level.

To get a true 71-inch reading:
- Find a flat, uncarpeted floor.
- Take your shoes off. Seriously.
- Stand with your heels, butt, and shoulder blades against the wall.
- Look straight ahead. Don't tilt your chin up; that actually makes you shorter because it compresses the back of your neck.
- Have someone place a flat object (like a hardback book) on your head, perpendicular to the wall.
- Mark the bottom of that object.
If you’re 5 foot 11 inches in inches, the mark will be exactly 5 feet and 11 inches from the floor. But keep in mind, you are actually taller in the morning. Gravity compresses the discs in your spine throughout the day. You might wake up at 71.25 inches and go to bed at 70.75 inches. Our bodies are basically fleshy accordions.
Practical Steps for the 71-Inch Crowd
Knowing your exact height in inches isn't just for vanity. It's for logistics.
- Check your bike frame. If you're 71 inches, you're usually looking at a 56cm to 58cm road bike frame or a Large mountain bike. Don't let a salesperson talk you into a Medium unless you have unusually short legs.
- Buy the right desk. The "standard" desk height is 29 to 30 inches. For someone who is 5'11", this is usually fine, but you might find your shoulders hunching. A chair with adjustable armrests is your best friend to bridge that 71-inch gap between your torso and the floor.
- Tailor your pants. Most 5'11" men have a 32-inch inseam. If you buy "off the rack," check if the brand runs long. A 71-inch person wearing pants that are too long looks shorter than they actually are.
At the end of the day, being 5'11" means you're taller than most of the world. It’s a height that fits into cars, airplanes (mostly), and clothing racks without much drama. 71 inches is the height of a person who is tall enough to be noticed but not so tall that they're constantly hitting their head on low doorways.
Stop worrying about that 72nd inch. It’s overrated.
Actionable Insight: If you're shopping for furniture or a new vehicle, use the 71-inch figure to check "clearance" specs rather than the "5'11" shorthand. Many technical manuals list interior dimensions in inches only, and knowing your 71-inch stature helps you quickly determine if you'll have enough legroom (usually 40+ inches needed) or headroom in a compact SUV. For clothing, specifically when buying suits, 71 inches is the cut-off where you should decide between a "Regular" and a "Long" jacket based on your torso length—if your torso is longer than 30 inches from the base of your neck to your waist, try the "Long" fit first.
