This article settles the discrepancy once and for all with the precise math and explains why the confusion keeps happening.

Is 178cm 5’8″ or 5’10”?

The exact conversion of 178 cm to feet and inches

Using the standard factor of 1 foot = 30.48 cm, defined by the National Institute of Standards and Technology (NIST), 178 cm divided by 30.48 gives exactly 5.8399 feet. To get inches, take the decimal 0.8399 and multiply by 12: that yields 10.08 inches. So the accurate result is 5 feet 10.1 inches.

• 178 ÷ 30.48 = 5.8399 feet (RapidTables converter)
• 0.8399 × 12 = 10.08 inches

Why rounding creates two different answers

The 5’8″ figure appears when someone rounds down the entire 5.84 feet to the nearest half-foot — a non-standard practice usually seen in casual conversation or older measurement systems. The 5’10” figure comes from the correct conversion, since 178 cm is only 2.3 cm short of 5’10” (177.8 cm). The RapidTables conversion page notes this exact ambiguity between decimal-feet and rounded feet-and-inches displays.

How to manually convert centimeters to feet

The Calculator Soup height converter provides the formulas: feet = cm ÷ 2.54 ÷ 12, or inches = cm ÷ 2.54. For 178 cm: 178 ÷ 2.54 = 70.08 inches total, then 70.08 ÷ 12 = 5.84 feet. The remainder after 5 feet is 70.08 – 60 = 10.08 inches.

The implication: if you see 178 cm listed as 5’8″, the source likely applied a non-standard rounding method. The correct rounded value is 5’10”.

Is 178 cm tall for a guy?

Average male height in the United States

According to CDC data, the average adult male height in the US is 5 feet 9 inches (175.3 cm). At 5’10.1″, a 178 cm man is 1.1 inches taller than the national average — placing him above roughly 70% of US men.

Where 178 cm ranks by global standards

The World Health Organization (WHO) Growth Reference Data shows the global male average at 5 feet 7 inches (171 cm). A 178 cm man is tall in almost every country outside Northern Europe, where averages such as 5’11″+ in the Netherlands shift the baseline upward.

Perceptions of height and attractiveness

In US dating contexts, 5’10” is often cited as an ideal height for men in surveys. For women, 5’10” is above the US female average of 5’4″ (CDC data) and is perceived as tall. Cultural factors heavily influence whether this is seen as an advantage — it varies widely by region and individual preference.

The pattern: 178 cm sits in a “tall but not exceptional” zone for men globally, while for women it crosses into noticeably tall territory.

Is 5’10” an attractive height?

Social perception of 5’10” for men

Multiple dating preference studies found that 5’10” is frequently cited by women as a minimum or ideal height for male partners. This aligns with 178 cm being above the US male average without exceeding typical social thresholds that are sometimes perceived as intimidating. Reddit discussions about 178 cm confirm many men consider 5’10” a “good” height to list on dating profiles.

Social perception of 5’10” for women

For women in the US, 5’10” is well above the average of 5’4″ (CDC data). A woman at this height is in approximately the 95th percentile for female height in the US, which some surveys describe as “very tall.” Perception varies: in modeling, 5’10” is common; in everyday social settings, it stands out.

Comparison to average and preferred dating heights

The WHO reference data places the global male average at 5’7″ and the global female average at 5’3″. At 5’10”, men are 3 inches above the global average; women are 7 inches above. This gap explains why 5’10” is seen as ideal for men (close to average, slightly taller) but extreme for women in many countries.

Why this matters: attractiveness judgments tied to height are deeply cultural, but 5’10” sits near the sweet spot for men while being a more polarizing height for women.

What height is considered tall?

Thresholds for tall in the US

In the United States, a man over 6’0″ (183 cm) is generally considered tall, while a woman over 5’7″ (170 cm) crosses the same threshold, according to CDC percentile distributions. At 178 cm (5’10.1″), a man is above the 80th percentile — meaning he is taller than 8 out of 10 American men.

Global tall height definitions

The WHO growth reference data shows that “tall” varies enormously: in South Korea, the male average is 5’9″, making 5’10” above the 85th percentile. In the Netherlands, where the male average is 6’0″, 5’10” is below average. 178 cm falls right at or above the 90th percentile for height in many Asian and Latin American countries.

How 178 cm fits the definition of tall

Using the Calculator Soup percentile reference, 178 cm is at roughly the 80th percentile for US men. That means: 20% of American men are taller, 80% are shorter. By most operational definitions (top 20-25%), 178 cm qualifies as tall for a man in the US and is clearly tall for a woman in any country.

The catch: tall is a moving target. For a person from a region with a short average height, 178 cm is markedly tall. For someone from Northern Europe, it’s average or slightly above.

What is 178 cm in feet and inches?

Conversion formula: cm ÷ 30.48 = feet

The standard conversion factor, defined by NIST, is 1 foot = 30.48 cm. To convert any height from centimeters to feet: divide by 30.48. For 178 cm: 178 ÷ 30.48 = 5.8399 feet.

Step-by-step calculation for 178 cm

• Step 1: 178 ÷ 30.48 = 5.8399 (decimal feet) (RapidTables converter)
• Step 2: The whole number 5 is the feet.
• Step 3: Multiply the decimal 0.8399 by 12 = 10.08 inches (The Calculator Site height chart)
• Result: 5 feet 10.1 inches

Quick reference conversion table for common heights

Seven heights around 178 cm, showing how small differences in centimeters translate to different feet-and-inches results.

The trade-off: notice that 179 cm is 5’10.5″ — still not 5’11”. The jump to 5’11” only happens at 180.34 cm. This illustrates why rounding up from 178 cm to 5’11” is mathematically unsupported.

Is 178 cm 5 foot 11?

Why 178 cm is often mistaken for 5’11”

The confusion stems from proximity: 5’11” equals 180.34 cm. At 178 cm, you’re only 2.34 cm (just under an inch) shorter. Many people round up in casual conversation, especially on dating profiles or in sports contexts where a taller height is culturally preferred. A Reddit discussion highlighted this exact pattern: users with 178 cm often report being called 5’11” by friends or listed as such online.

The 180 cm = 5’11” conversion

Using the standard 30.48 factor, 180 cm ÷ 30.48 = 5.9055 feet, which is 5 feet 10.9 inches — close to 5’11” but still not there. The precise conversion for 5’11” is 180.34 cm. So 178 cm is fully 2.34 cm (0.92 inches) short of 5’11”.

Common rounding errors in everyday conversation

• Rounding 5.84 feet to 6 feet: that would be 183 cm — a 5 cm error.
• Rounding 70.08 inches to 71 inches: that equals 5’11” (180.34 cm) — a 2.26 cm error.
• Rounding to the nearest half-foot: 5.84 feet rounds to 6.0 feet in some rough systems.

The catch: 179 cm, at 5’10.5″, still isn’t 5’11”. Only at 180.34 cm does the math support that claim. If you’re 178 cm, you’re solidly 5’10”.

Quick comparison: 178 cm vs. common height references

Four data points, one pattern: 178 cm is above average in every US demographic but below the top percentile globally.

Summary

178 cm equals exactly 5 feet 10.1 inches — not 5’8″, not 5’11”. The persistent rounding confusion arises when non-standard rounding methods (half-foot or casual up-rounding) replace the correct conversion. For a US reader who is 178 cm, the implication is clear: you are above average and in a favorable height bracket for most dating and social contexts, but the number on your driver’s license should be 5’10”, not 5’8″ or 5’11”.
