How to Read Height in Feet and CM

A simple guide to reading and converting height between feet, inches, centimetres, and metres, with exact formulas and a quick reference table for common heights.

Height can be read in feet and inches or in centimetres, and both formats describe the same measurement. The easiest way to understand a height is to convert it into one format, then use a visual chart to see how that height looks next to another person or object.

For example, 5'10" is 70 total inches, which is about 178 cm. A person who is 6'0" is 72 total inches, or about 183 cm. The written difference looks small, but a 5 cm difference is visible when both heights are drawn to the same scale in the HeightComparative tool.

What does feet and inches mean?

Feet and inches are imperial height units. One foot contains 12 inches, so a height written as 5'8" means 5 feet plus 8 inches.

To read it correctly:

Written heightHow to read itTotal inchesApprox. cm
5'0"Five feet zero inches60 in152 cm
5'4"Five feet four inches64 in163 cm
5'8"Five feet eight inches68 in173 cm
6'0"Six feet zero inches72 in183 cm
6'4"Six feet four inches76 in193 cm

The apostrophe means feet. The quotation mark means inches. In casual writing, people often type 5 ft 8 in, 5 feet 8 inches, or 5'8. They all usually mean the same thing.

How centimetres work for height

Centimetres are metric units. They are simpler for calculation because the number is already a single value. A person who is 178 cm tall is simply 178 centimetres from the floor to the top of the head.

Metric height is common in many countries because it avoids the extra step of splitting a height into feet and inches. It is also easier for comparison. If one person is 178 cm and another is 165 cm, the difference is 13 cm.

Metric heightApprox. feet and inchesCommon written form
150 cm4'11"4 ft 11 in
160 cm5'3"5 ft 3 in
170 cm5'7"5 ft 7 in
180 cm5'11"5 ft 11 in
190 cm6'3"6 ft 3 in
200 cm6'7"6 ft 7 in

These are rounded conversions. A precise calculator may show a nearby value with decimal inches, such as 5'10.1". For most height comparisons, the rounded inch value is easier to read.

Height conversion formula

You can convert height manually with two simple formulas:

ConversionFormulaExample
Feet and inches to inchesfeet x 12 + inches5'10" = 5 x 12 + 10 = 70 in
Inches to cminches x 2.5470 in x 2.54 = 177.8 cm
Cm to inchescm / 2.54178 cm / 2.54 = 70.1 in
Inches to feet and inchesdivide by 1270 in = 5 ft 10 in

So 5'10" is 177.8 cm, usually rounded to 178 cm. If you want a quick conversion without doing the math, use the height calculator.

Quick height conversion chart

Use this chart for common adult heights. The centimetre values are rounded to the nearest whole number.

Feet and inchesCentimetresDifference from 5'8"
5'0"152 cm-20 cm
5'2"157 cm-15 cm
5'4"163 cm-10 cm
5'6"168 cm-5 cm
5'8"173 cm0 cm
5'10"178 cm+5 cm
6'0"183 cm+10 cm
6'2"188 cm+15 cm
6'4"193 cm+20 cm

This kind of table is useful for reading numbers, but it still does not show body scale. A visual chart is better when you want to compare two people side by side.

Why 5 cm can look different in real life

A 5 cm difference is about 2 inches. It can look subtle when two people are far apart, sitting down, wearing different shoes, or standing at different angles. It becomes easier to see when both people stand on the same baseline.

That is why height comparison charts use a floor line. The tool places each subject on the same ground level, then scales the silhouette to match the selected height.

DifferenceApprox. inchesHow it usually appears
2 cm0.8 inVery small difference
5 cm2.0 inNoticeable side by side
10 cm3.9 inClear difference
15 cm5.9 inLarge difference
20 cm7.9 inVery obvious difference

If you are comparing celebrities, remember that listed heights are often reported values. Use them as approximate references, not guaranteed medical measurements.

Feet and inches vs cm for celebrity heights

Celebrity height pages often show both units because readers search in different formats. A basketball fan may think in feet and inches, while someone using metric countries may prefer centimetres.

For example, LeBron James is listed at 6'9" or 206 cm. Kevin Hart is listed at 5'4" or 163 cm. The difference is 43 cm, which is easier to understand when you view LeBron James vs Kevin Hart as a scaled comparison.

Common height reading mistakes

The most common mistake is treating inches like decimals. A height of 5'10" is not 5.10 feet. It means 5 feet and 10 inches.

Here is the difference:

Written valueCorrect meaningWrong interpretation
5'10"5 feet + 10 inches5.10 feet
6'2"6 feet + 2 inches6.2 feet
5.5 ft5 feet + 6 inches5 feet + 5 inches

Decimal feet are used in some technical contexts, but everyday height usually uses feet plus inches.

Best way to compare two heights

For quick reading, convert both heights to centimetres. For visual understanding, place both heights on the same chart.

The clean workflow is:

  1. Convert both heights to the same unit.
  2. Subtract the shorter height from the taller height.
  3. Draw both subjects from the same floor line.
  4. Label both heights in cm and ft/in.

HeightComparative does these steps automatically. You can add a custom person, choose a celebrity, set the height, and export the result as a PNG.

Summary

Feet and inches are split units, while centimetres are a single metric value. To compare heights accurately, convert both measurements into the same unit first. A table can help with quick conversion, but a visual height chart is better for seeing the real scale difference between people, celebrities, and objects.
