Heads of state throughout the world and at all periods of history may be ranked according to characteristics such as length of time holding that position; age of accession or death; or physical attributes.

The next contender is the unnamed daughter of Emperor Xiaoming of Northern Wei who was appointed by her grandmother, Empress Dowager Hu. She reigned for a matter of hours until being replaced by Yuan Zhao.
In more recent history, Dipendra was the undisputed king of Nepal for only around 37 hours in 2001, after perpetrating the massacre of his father the king and his family.

Ruling houses
Oldest
Officially, the current Emperor of Japan, Naruhito is the 126th in line from the first emperor, Jimmu, who is variously believed to have reigned in the 1st or 7th century BC. The earliest documented evidence is only for the 29th emperor, Kinmei (AD 509–571); however, this is sufficient such that even the most conservative of estimates still places the Japanese imperial family as among the oldest lines in the world today.
Post-nominal numbers
The highest post-nominal number representing a member of a royal house is 75, used by Count Heinrich LXXV Reuss zu Schleiz (r. 1800–1801). All male members of the branch were named Heinrich, and were successively numbered from I upwards, from the beginning of each century.
Physical attributes
- Tāufaʻāhau Tupou IV, the heaviest head of state
- Sancho VII of Navarre, the tallest verifiable ruler
- Benito Juárez, the shortest head of state
Heaviest
The heaviest monarch is believed to have been Tāufaʻāhau Tupou IV, King of Tonga from 1965 to 2006, who at his peak in 1976 was measured as being 208.7 kg (460 lb, or 32 st 12 lb), though he subsequently lost around 40% of his weight.
Tallest
The tallest height of a president is that of Filip Vujanović of Montenegro standing at 6 ft 7 in (2.01 m) tall.
One of the tallest rulers in history was Dusan the Mighty, who was King of Serbia (1331–1345) and later Tsar of Serbs, Greeks, and Bulgarians (1346–1355). He was 214 centimetres (7 ft 0 in) tall, in that time the average height was 165–170 centimetres (5 ft 5 in – 5 ft 7 in), so he searched all over Europe to find 101 men over 2 metres (6 ft 7 in) tall to be part of his personal guard.
On the other hand, Herodotus wrote in Histories (7:117) that "Xerxes was in stature the tallest of all the Persians, falling short by only four fingers of being five royal cubits in height." A royal cubit is assumed to be a bit more than 20 English inches (52 cm), which makes Xerxes almost 8 feet tall (2.43 m), though this is likely legendary. Sancho VII of Navarre was reported to be 7 ft 4 in (2.24 m).
Shortest
President Benito Juárez of Mexico was reportedly the shortest world leader, standing at 4 ft 6 in (1.37 m).
The shortest monarch is Queen Victoria of the British Empire, who was believed to be around 4 ft 9 in (1.45 m). Two Egyptian pharaohs were also said to be very short, Cleopatra VII was said to be 5 ft 0 in (1.52 m) and Amenhotep I is claimed to be the shortest male monarch at 5 ft 4 in (1.63 m).
