170 cm in Feet: Exact Conversion, Height Guide & Health Context

If you’ve ever found yourself staring at a height listed in centimeters and wondered how that stacks up in feet and inches, you’re not alone. The number 170 cm lands right at a familiar borderline — short of 5’7″ by less than an inch, yet often rounded up in everyday conversation. This guide gives you the exact conversion, how 170 cm compares for women and men, what it means for modeling, and where it fits into healthy weight guidelines.

Exact height of 170 cm in feet and inches: 5 feet 6.9 inches · Rounded height for colloquial use: 5’7″ · Conversion factor (1 foot): 30.48 cm · Total inches in 170 cm: 66.93 inches

Six key facts, one pattern: the same number — 170 cm — carries different meaning depending on whether you’re converting, comparing genders, or evaluating health.

Is 170 cm 5’6″ or 5’7″?

Exact conversion of 170 cm to feet and inches

At the most precise level, 170 cm equals 5 feet and 6.92913 inches. That’s 5 feet plus 0.57743 feet — the decimal remainder is multiplied by 12 to get the inches: 0.57743 × 12 = 6.92916 inches (RapidTables). In other words, it is not exactly 5’7″. It falls just shy of that mark.

Why 170 cm is commonly rounded to 5’7″

• Rounding to the nearest whole inch pushes the 6.9 inches up to 7 inches (Inch Calculator, height conversion tool).
• In casual conversation, saying “5’7″” is simpler and the difference of 0.07 inches is imperceptible.
• Many online converters and driver’s licenses round to the nearest inch by default (The Calculator Site).

Bottom line: 170 cm is 5’6.9″. Saying 5’7″ is rounding, not truth — but it’s the universally accepted rounding in everyday use. Actors: height-conscious individuals should use the exact figure for official documents; everyone else can comfortably round.

Is 170 cm tall for a girl?

Average female height in the United States

The average American woman stands at 5’4″ (163 cm), according to the CDC (US health authority). So a woman who is 170 cm is a full 3 inches taller than average — she is tall by US standards.

How 170 cm compares to female height averages globally

• In the Netherlands (tallest nation), average female height is around 5’7″ (170 cm) (Our World in Data, global health data platform).
• In most Asian and Latin American countries, average women are 5’2″ to 5’4″, making 170 cm noticeably tall.
• In many European nations, 170 cm is common and not considered unusual.

Bottom line: For a woman, 170 cm is above average in most countries (especially the US). Women in fashion or sports may actually benefit from the extra height. The implication: if you’re 170 cm female, own the tall — it’s a statistical advantage in many contexts.

Is 5’7″ tall for a guy?

Average male height in the United States

According to the CDC (US health authority), the average adult male height in the US is 5’9″ (175 cm). A man at 5’7″ (170 cm) is 2 inches below average, placing him in the shorter half of the male population.

Global comparison of 5’7″ for men

• In many East Asian countries (Japan, South Korea, Vietnam), average male height ranges from 5’5″ to 5’8″, so 5’7″ is close to the norm (Our World in Data).
• In Northern Europe (e.g., Netherlands, Denmark), average male height exceeds 5’11”, making 5’7″ well below average.
• In parts of South Asia and Southeast Asia, 5’7″ is slightly above average.

The pattern: the same height flips from short to average depending solely on geography.

Can a 170 cm guy be a model?

Male model height requirements

Traditional high-fashion runway shows typically prefer male models between 5’11” and 6’2″ (180–188 cm). A 170 cm (5’7″) model would be too short for those specific roles. However, commercial modeling — which includes e-commerce, lifestyle brand campaigns, and fitness modeling — has much looser height standards. Many commercial clients look for a “relatable” look rather than towering proportions (BBC Culture, editorial analysis).

Types of modeling that accept shorter heights

• Commercial modeling: catalogs, online stores, fitness ads — often no minimum height.
• Parts modeling: hands, feet, face — height irrelevant.
• Character and niche modeling: theme parks, historical reenactments, costume modeling.

Bottom line: A 170 cm guy can absolutely model, but not on the Paris runway. Men seeking commercial or niche modeling should contact agencies that don’t enforce strict height minimums. For high fashion, the gap is real: you need 180 cm+.

Is 170 a healthy weight for a 5’7″ woman?

BMI guidelines for a person of 5’7″

The CDC (US health authority) defines a healthy BMI range as 18.5–24.9. For a height of 5’7″ (170 cm), that range corresponds to a weight of 118 to 159 pounds (53.5 to 72 kg).

Healthy weight range for 5’7″ based on CDC data

• Underweight: below 118 lbs
• Normal weight: 118–159 lbs
• Overweight: 160–191 lbs
• Obese: 192 lbs and above

A weight of 170 pounds falls into the overweight category (BMI ≈ 26.6) (World Health Organization, global health body). However, BMI does not account for muscle mass or body composition. An athlete with high muscle mass may have a BMI of 26-27 but be perfectly healthy.

What this means: the number 170 in weight is not inherently unhealthy — context matters.

How to convert 170 cm to feet manually

Follow these simple steps to convert any centimeter height to feet and inches without a calculator.

1. Divide by 30.48 (the number of cm in one foot): 170 ÷ 30.48 = 5.57743 feet (RapidTables).
2. Take the whole number as feet: 5 feet.
3. Subtract the whole part: 5.57743 – 5 = 0.57743 feet.
4. Multiply the decimal by 12 to get inches: 0.57743 × 12 = 6.92916 inches (Inch Calculator).
5. Round if desired: 6.92916 inches rounds to 6.9 inches, or to the nearest whole inch = 7 inches.

That gives you 5’6.9″ or, rounded, 5’7″. For another quick conversion, see our guide on 175 cm to Feet.

Comparison: 170 cm vs. average heights by gender and country

Three comparisons, one story: 170 cm is a chameleon — tall for some, average for others, short for a few.

Bottom line: The same height — 170 cm — can be tall, average, or short depending on your gender and country. For a woman in most places, it’s a plus; for a man in the US, it’s below average. The pattern: context is everything.
