13 world leaders ranked by how tall they are

• World leaders vary widely in height, though many try to project the image of being taller than they are.
• We often see them photographed together, allowing us to see just how much their heights can vary.
• Here's how they stack up, from the president of Serbia coming in at 6 feet, 6 inches — or 198 centimeters — and Ireland's leader coming in at 5-foot-3, or 160 centimeters.

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 actual height can be something of a surprise.

Here's the height of 13 world leaders and how they compare with their counterparts. They are ranked from shortest to tallest.

North Korea's Kim Jong Un: Between 5-foot-4 (163 cm) and 5-foot-7 (170 cm)

The North Korean leader is often reported to be 5-foot-7, but it is unclear where that information comes from.

He appears to be shorter than South Korean President Moon Jae-in (pictured above), who is 5-foot-6, but experts also think Kim is often pictured wearing shoes that make him seem taller, which could mean he could be as short as 5-foot-4.

UK Prime Minister Rishi Sunak : 5 feet, 6 inches (170 cm)
