Studies have shown that voters lean toward taller politicians, viewing them as better suited to leadership.
But the world's leaders fill the whole spectrum, with some topping 6 feet and others closer to 5 feet tall.
World leaders don't always publicize their height, which means estimating often comes down to comparing them as they stand beside one another or with other celebrities whose heights are public.
Some world leaders even go out of their way to seem taller than they are, so their real height can be something of a surprise.

Angela Merkel: 5-foot-5 (165 cm)

The Guardian also highlighted photographs that showed Trump standing next to other people who were 6-foot-3 and looking slightly shorter.
