Height Comparison Calculator
Compare heights side by side and see the difference in centimetres and feet and inches.
About the Height Comparison Calculator
List each person with their height, one per line, in centimetres (162) or feet and inches (5'11"). The calculator finds the tallest and shortest, shows the gap in both units, and draws everyone to the same scale, which is handy for couples, siblings, a child's growth, or checking how tall someone will look next to you.
One inch is exactly 2.54 cm and one foot is 30.48 cm, so conversions are exact.
The formula
Difference = taller − shorter; cm = inches × 2.54
Worked example
Asha 162 cm, Ben 5'11", a child 120 cm
- Ben: 71 in × 2.54 = 180.34 cm
- Ben vs Asha: 18.3 cm (7.2 in) taller
- Ben vs child: 60.3 cm (23.8 in); the child is 67% of Ben's height
Things to keep in mind
- Uses heights as entered: shoes can add 2–5 cm, and people often round their height up.
