Height differences between two people

The gap between two heights, shown in both centimetres and inches.

Person A	Person B	Difference (cm)	Difference (in)	Taller
170 cm	180 cm	10.0	3.9	B
160 cm	175 cm	15.0	5.9	B
180 cm	165 cm	15.0	5.9	A
155 cm	190 cm	35.0	13.8	B
175 cm	175 cm	0.0	0.0	Equal

One inch is 2.54 cm, so a 10 cm gap is just under 4 inches.

A simple subtraction, made unit-friendly

The math here is trivial (just a subtraction), but the real value is handling the unit conversion cleanly between centimetres and inches so you're not doing that math by hand.

Common uses

Comparing heights for clothing sizing, curiosity about a height difference between partners or family members, or converting a height mentioned in one unit system to your own.

Frequently asked questions

How do I convert cm to feet and inches?

Divide centimetres by 2.54 to get total inches, then divide by 12 for feet and use the remainder as inches. Example: 175 cm ÷ 2.54 = 68.9 inches = 5 feet 8.9 inches. Quick reference: 160 cm = 5'3", 170 cm = 5'7", 180 cm = 5'11", 190 cm = 6'3".

What is the average height for men and women?

Global averages vary by country. In the US: men average 175.3 cm (5'9"), women average 161.3 cm (5'3.5"). In the Netherlands (tallest country): men average 183.8 cm (6'0"), women 170.4 cm (5'7"). In India: men average 166.5 cm (5'5.5"), women 152.6 cm (5'0").

When do people stop growing taller?

Most girls reach full height by 14–16, most boys by 16–18, though some grow into their early 20s. Growth plates in the bones fuse under hormonal influence during puberty. After that, height can only decrease (very gradually, from spinal disc compression with age — about 1 cm per decade after 40).
