You're standing in a fitting room or maybe filling out a visa application, and there it is: 175 cm. It’s a number that feels substantial in metric but looks like a total mystery if you grew up thinking in feet and inches. Honestly, most of us just want the quick answer so we can move on with our lives.
Converting 175 centimeters to inches isn't just about moving a decimal point. It’s about 68.8976 inches, to be exact. But let's be real—nobody says they are 68.89 inches tall. That would be weird. In the real world, you're looking at roughly 5 feet and 9 inches.
Why does this specific number matter so much? Because 175 cm is a fascinating "middle ground" in human biology. It sits right at the edge of several different cultural and ergonomic standards.
Doing the Math Without Losing Your Mind
Let's look at the actual physics of this conversion. The international yard and pound agreement of 1959 settled it once and for all: one inch is exactly 25.4 millimeters. That means to get from centimeters to inches, you divide by 2.54.
$$175 / 2.54 = 68.8976378$$
If you’re trying to visualize this, think of a standard ruler. An inch is roughly the length of the top joint of your thumb. Now imagine sixty-eight of those stacked up. It’s a lot.
Most people mess this up because they try to round too early. They think, "Oh, 2.5 is close enough." If you divide 175 by 2.5, you get 70 inches. That’s 5'10". You just accidentally grew an inch! In the world of tailoring or medical records, that missing inch is a big deal. Always use 2.54 if you want to be accurate.
Breaking it Down into Feet
Since we don't live in a world of raw inches, we have to convert that 68.89 number into feet. You take 68, divide by 12, and you get 5 with a remainder of 8. So, you are 5 feet and 8.89 inches.
For all intents and purposes, you’re 5'9".
Is 175 cm Tall? It Depends on Where You’re Standing
Height is relative.

If you are a 175 cm man in the Netherlands, you might feel a bit short. The average Dutch male is hovering around 183 cm (about 6 feet). You'd be looking up at a lot of people in Amsterdam.
But head over to Vietnam or many parts of Southeast Asia, and 175 cm makes you a giant. In those regions, the average male height is often closer to 162-165 cm.
In the United States, the CDC (Centers for Disease Control and Prevention) suggests the average height for an adult male is roughly 175.4 cm. So, 175 cm is basically the definition of "average." You are the baseline. You are the person car manufacturers design seats for. You are the reason "Medium" shirts exist.
The Fashion Gap
Fashion designers use 175 cm as a pivot point. If you’re shopping for high-end European brands, they often cut their "Regular" fits based on a model who is roughly this height.
However, there’s a catch.
Inseam lengths are where the conversion from 175 centimeters to inches really bites you. A person who is 175 cm tall usually has an inseam of about 30 to 32 inches. If you buy "Long" pants, you’ll be tripping over your hems. If you go "Short," you’re showing off your socks. It’s a delicate balance.
The Health Implications of 175 cm
Medical professionals use the metric system for a reason. It’s precise. When calculating Body Mass Index (BMI), that 175 cm figure is the denominator.
$$BMI = kg / m^2$$
At 1.75 meters tall, your "healthy" weight range is surprisingly broad. According to the World Health Organization (WHO), a healthy BMI is between 18.5 and 24.9. For someone who is 175 cm, that means weighing anywhere between 57 kg (125 lbs) and 76 kg (167 lbs).

Real-World Scaling: More Than Just Height
We talk about 175 cm in terms of people, but it’s a standard size for plenty of other things.
- Skis: A 175 cm ski is a very common length for intermediate to advanced male skiers. It provides a good balance between stability at high speeds and the ability to turn quickly.
- Home Decor: Many standard curtains are sold in lengths of 175 cm (though 160 and 210 are more common).
- Yoga Mats: Most standard mats are about 173-180 cm long. If you are 175 cm, you are officially the exact length of your yoga mat. Your head and feet will be right on the edges during Savasana.
Common Misconceptions About the Conversion
People often ask: "If I'm 175 cm, am I closer to 5'8" or 5'9"?"
Mathematically, you are much closer to 5'9".
0.89 of an inch is nearly a full inch. It’s about 2.2 centimeters. In the world of dating apps or sports rosters, most people who are 174.5 cm will claim 175 cm, and anyone who is 175 cm will claim 5'9". It’s just how the human ego works.
The "Five-Foot-Ten" Myth
There’s a weird psychological phenomenon where people want to be 5'10" (roughly 178 cm). In the US, 5'10" is seen as "solidly tall." 175 cm feels just a hair short of that.
But honestly? Most people can't tell the difference between 175 cm and 178 cm in person. It’s about 1.2 inches. Unless you’re standing back-to-back, it’s invisible.
How to Convert 175 cm to Inches in Your Head
You’re at a store. You don't have a calculator. You see a rug that is 175 cm long. How do you know if it fits your 6-foot hallway?

Use the "Rule of 10."
- Know that 10 cm is about 4 inches (it’s actually 3.93, but 4 is easier).
- 170 cm is 17 units of 10 cm.
- 17 x 4 = 68 inches.
- Add that extra 5 cm (which is about 2 inches).
- 68 + 2 = 70 inches.
Your mental math gives you 70 inches. The real answer is 68.9. You’re within an inch of accuracy! That’s usually enough to know if a rug will fit in your car.
Why the US Won't Switch to Centimeters
It’s a common frustration. Why are we still talking about 175 centimeters to inches? Why can't we just use one system?
The US actually did try to switch. The Metric Conversion Act of 1975 was supposed to move the country toward the International System of Units. It failed because it was voluntary.
The cost to change every road sign, every screw thread, and every medical record was deemed too high. So, we live in this weird hybrid world where we buy 2-liter soda bottles but measure our height in feet. We use grams for nutrition labels but pounds for our body weight.
It’s messy. It’s confusing. But it makes for great trivia.
Actionable Steps for Using 175 cm Measurements
If you've realized you are 175 cm or need to work with this measurement, here is what you should actually do:
- Check your bike frame: If you are 175 cm tall, you usually fit a "Medium" or a 54cm–56cm road bike frame. Don't let a salesperson talk you into a "Large" unless you have unusually long arms.
- Update your ID: If your driver’s license says 5'8" and you’re actually 175 cm, you’re selling yourself short. You are officially 5'9".
- Measure your workspace: If you are 175 cm, your desk height should ideally be around 70-72 cm (about 28 inches) for perfect ergonomics.
- Tailoring: If you're buying a suit, ask for a "38R" or "40R." The "R" stands for Regular, which is designed precisely for the 175 cm to 180 cm height range.
Stop guessing. 175 cm is 68.9 inches. It's 5'9". It's the most common, average, and standardized height in the modern world. Embrace the middle.
