The following table summarizes the key metric equivalents for 5’11”.

Is 180 cm 5 ft 11?

That question trips up more people than you’d expect. Here’s the short answer: almost, but not quite.

Why 180 cm is not exactly 5’11”

The difference is tiny — 0.34 centimeters, about the thickness of two credit cards stacked. But technically, 180 cm equals 5 feet 10.87 inches, while 5’11” is exactly 180.34 cm (Inch Calculator).

The precise conversion: 180.34 cm

Here’s the math: five feet is 60 inches, plus 11 inches gives you 71 total inches. Multiply 71 by 2.54, and you land on 180.34 (RapidTables).

The implication: when a dating profile says “5’11” and their driver’s license says “180 cm,” they’re technically rounding up by 0.34 cm. Most people won’t notice — but the tape measure does.

Is 178 cm 5’10 or 5’11?

This is the second most common height confusion online. Someone claims they’re 5’11” at 178 cm, and someone else jumps in to correct them. Who’s right?

Precise conversion of 178 cm to feet and inches

178 centimeters converts to 5 feet 10.078 inches — which rounds down to 5’10” (The Calculator Site).

Why some sources round 178 cm to 5’10”

Because 5’10” is 177.8 cm (Bajaj Finserv). The 0.2 cm difference is negligible, so rounding down is standard. Claiming 178 cm as 5’11” requires rounding up by a full 2.34 cm — not exactly accurate.

• 178 cm = 5’10” (rounded) — supported by The Calculator Site
• 178 cm is 0.36 cm short of 5’11” (180.34 cm) (Inch Calculator)
• 179 cm = 5’10.47″ — still closer to 5’10” than 5’11” (RapidTables)

The pattern: every centimeter below 180.34 puts you closer to 5’10” than 5’11”. The trade-off is that in everyday conversation, people fudge upward — but in medical records, it’s always precise.

Is 5’11” considered tall for a man?

Depends on where you stand — and who’s standing next to you.

Average male heights in the US and worldwide

The average adult male in the United States is 5 feet 9 inches (175.26 cm) (CDC). Worldwide, the average drops to 5 feet 7 inches (170.18 cm) (World Population Review).

Percentile of 5’11” among men

At 5’11”, a man is taller than about 70% of U.S. men and roughly 85% of global men. That puts him solidly above average — tall, but not exceptionally so.

What this means: if you’re a 5’11” man in the U.S., you’re in the comfortable zone — tall without the practical downsides (low ceiling clearance, hard-to-find trousers) that come with 6’3″+.

What height is considered tall?

The answer shifts depending on gender, geography, and even generation.

Tallness thresholds in the US

In the United States, tall for a man generally starts at 5’10” (177.8 cm) (CDC). For women, tall starts at 5’7″ (170.18 cm) (CDC).

Tallness thresholds around the world

The tallest countries — Netherlands, Denmark, Norway — set the bar higher, with tall defined as 6’0″ (183 cm) or above for men (World Population Review). In parts of Southeast Asia, 5’9″ is already considered tall.

The pattern: tallness is relative to the local average. A 5’11” man is tall in the U.S. but average in the Netherlands.

Is 5’10” tall for a woman?

Short answer: yes.

Average female heights

The average adult woman in the United States stands at 5 feet 4 inches (162.56 cm) (CDC). Globally, the average is around 5’3″ (160 cm) (World Population Review).

Perception of 5’10” women

A woman at 5’10” (177.8 cm) is taller than roughly 95% of women in the U.S. — clearly tall in any room she walks into. She’s roughly the same height as the average American man.

The catch: 5’10” is an inch shorter than 5’11”, but for women the perception gap is small. A woman at 5’10” is tall; at 5’11”, she’s noticeably tall.

How to convert feet and inches to centimeters

Three steps, one formula, no rounding needed.

1. Convert feet to inches: Multiply the feet by 12. For 5’11”: 5 × 12 = 60 inches.
2. Add the remaining inches: 60 + 11 = 71 inches total.
3. Multiply total inches by 2.54: 71 × 2.54 = 180.34 cm (RapidTables).

The formula works for any height: centimeters = (feet × 30.48) + (inches × 2.54) (RapidTables).
