What is 5ft 8 height in cm?
Conversion formula
The international inch was defined as exactly 25.4 millimeters (2.54 centimeters) back in 1959, and every accurate height converter since then has used that same definition, according to RapidTables (conversion reference site). That means your height in centimeters is always a fixed calculation away — no approximation involved.
- 1 inch = 2.54 cm
- 1 foot = 30.48 cm (12 inches × 2.54)
Step-by-step calculation
Converting 5’8″ to centimeters takes three quick steps, as shown by Inch Calculator (precision conversion tool):
5 feet = 60 inches + 8 inches = 68 total inches × 2.54 cm/inch = 172.72 cm
This result — 172.72 cm — is verified across SplashLearn (math education platform), The Calculator Site (conversion chart database), and BYJU’S (educational calculator). BYJU’S specifically confirms that 8 inches equals 20.32 cm as part of their inches-to-cm chart.
The implication: if a converter gives you any number other than 172.72 for 5’8″, it’s either rounding for display or using a different rounding method — not the exact international standard.
Is 172 cm 5’8″ or 5’9″?
Exact breakdown
Here’s where things get tricky. The exact value 172.72 cm is 5’8″ — but if you input 172 cm into a reverse converter, you get a different answer. The Calculator Site (comprehensive bidirectional tables) shows that 172 cm converts to exactly 5 feet 7.72 inches, which is closer to 5’8″ than 5’7″ but not an exact match.
If you enter 172 cm, some calculators round down to 5’7″ (since 7.72 inches rounds to 7). Others round up to 5’8″ for simplicity. Only the exact 172.72 cm value corresponds precisely to 5’8″.
Rounding differences
Omni Calculator (metric conversion tool) demonstrates the math: 172 ÷ 30.48 = 5.647 feet, and 0.647 × 12 = 7.76 inches. The slight variation from 5’7.72″ in some charts comes from how many decimal places are carried through the calculation.
This table shows how different centimeter inputs map to their feet-and-inches equivalents, highlighting the gray zone around 172 cm.
| Input (cm) | Exact feet-inches | Common rounded label |
|---|---|---|
| 170.18 | 5’7″ | 5’7″ |
| 172 | 5’7.72″ | Sometimes labeled 5’7″, sometimes 5’8″ |
| 172.72 | 5’8″ | 5’8″ (exact) |
| 175.26 | 5’9″ | 5’9″ |
The pattern: 172 cm sits in a gray zone where different tools make different calls. If precision matters — for clothing sizes, medical records, or official documents — use 172.72 cm explicitly.
Is 175 cm 5’8 or 5’9?
Why converters vary
This is probably the most common source of confusion online. Vedantu (educational calculator) shows that 175 cm converts to 5 feet 8.9 inches — nearly 5’9″ but not quite there. The math, per Omni Calculator, is: 175 ÷ 30.48 = 5.741 feet, and 0.741 × 12 ≈ 8.9 inches.
175 cm equivalents
The 175 cm case shows exactly why rounding creates confusion. Some converters display 175 cm as “5’9″” because 8.9 inches rounds up to 9, as explained by The Calculator Site. But the true value — 175.26 cm — is the one that corresponds to an exact 5’9″.
Medical tables like Miami Med’s Appendix J round 5’8″ to 173 cm for clinical data acquisition, per the University of Miami (medical institution). That’s a deliberate simplification, not an error — but it won’t match what an online converter shows you.
What this means: 175 cm is closer to 5’9″ than 5’8″ by about 0.26 cm. If a site calls it 5’8″, it’s rounding down for display purposes. The exact value is 5’8.9″, which rounds up to 5’9″ in most everyday contexts.

Average heights by region
Average male height varies significantly by country. According to GigaCalculator (height comparison tool), the US male average sits around 5’9″ (175.26 cm), which puts 5’8″ at roughly 2.54 cm (1 inch) below that average. UHSussex NHS (UK health authority) confirms similar metrics in clinical charts from 2023.
Perception factors
Height perception is culturally shaped. In some Nordic countries, averages run taller — meaning 5’8″ might fall below the local median. In many Asian and Latin American countries, the same height could be considered above average, as GigaCalculator notes in their regional comparisons.
If you’re comparing yourself to a “global average,” the answer depends entirely on which dataset you’re using. There’s no single universal average — the numbers shift based on the population studied.
The pattern: in the United States and much of Western Europe, 5’8″ is slightly below or at average for adult men. In countries with shorter average heights, it’s noticeably above median. Context determines whether 5’8″ feels “tall” or “short.”
Is 5’8″ tall or short for a guy?
Short kings context
The “short kings” movement in online spaces has reframed 5’8″ as respectable rather than short. This cultural shift accepts that 5’8″ — at 172.72 cm — is a functional, common height that doesn’t limit success, charisma, or appeal, despite occasional social pressure to be taller.
Dating and social views
Research and survey data consistently show height preferences in dating contexts, though these vary by generation and platform. GigaCalculator provides visual comparisons that put 5’8″ in context against common benchmarks — it’s 8 inches taller than 5’0″ and sits squarely in the middle of typical adult male ranges.
5’8″ is around average in many countries and above average in others. Whether that’s “tall” or “short” depends on your frame of reference — the data doesn’t support a definitive answer, only context-dependent ones.
For anyone comparing heights across international contexts, the key takeaway is simple: use the exact conversion (172.72 cm) and know that regional averages will color how that number is perceived. The math is precise; the interpretation is not.
How to convert feet and inches to cm
The formula in practice
Converting any height from feet and inches to centimeters follows this formula, per SplashLearn (math vocabulary reference): total inches × 2.54 = centimeters. That’s it — multiply by 2.54, and you have your answer.
- Take your feet value and multiply by 12 to get inches
- Add any remaining inches
- Multiply the total by 2.54
- The result is your height in centimeters
5’6″ = 167.64 cm · 5’7″ = 170.18 cm · 5’8″ = 172.72 cm · 5’9″ = 175.26 cm · 5’10” = 177.80 cm · 6’0″ = 182.88 cm
Why this matters: once you know the formula, you can calculate any height without needing a tool. And if a tool gives you something different, you’ll know it’s either rounded or using a different standard.
