Prince Philip, Duke of Edinburgh, was the monarch's spouse from 6 February 1952 until his death on 9 April 2021, for a total of 69 years 62 days, making him the longest-serving consort overall. The queen consort with the longest tenure was Charlotte of Mecklenburg-Strelitz, who was George III's consort for 57 years, 70 days, between 1761 and 1818.
Charles III was the longest serving heir-apparent, Duke of Cornwall, and Duke of Rothesay, with a tenure of 70 years 214 days from 6 February 1952, and Prince of Wales, with a tenure of 64 years and 44 days from 26 July 1958 until ascending the throne on 8 September 2022.
Anne was the only heiress apparent in British history so she holds the record as the longest and shortest serving heiress apparent, with a tenure of 7 years and 70 days.
Margaret of Scotland, Countess of Kent was heir presumptive to William I of Scotland, Alexander II and Alexander III for a total of about 43 years, 14 days (her tenure as heir presumptive to Alexander II was also the longest single tenure at 26 years, 274 days). The longest-serving heir-presumptive of either sex was Robert II, who was heir-presumptive to Robert I and then David II for a total of 46 years, 353 days; he also served the longest single tenure (41 years, 260 days as heir-presumptive to David II).
Edward the Black Prince had the longest tenure as an heir who did not subsequently become monarch; he was heir apparent to Edward III for his lifetime of 45 years 357 days, but he died in 1376, one year before his father, who died in 1377.

### Shortest

The shortest-reigning monarch was Lady Jane Grey who ruled for 9 days from 6 July until 15 July 1553 (although she was only proclaimed queen by the Lords of the council on 10 July). Her husband Lord Guildford Dudley was her consort for the entire reign, making this the shortest tenure of the male consort of a female monarch. Note: Jane's reign is disputed.
The king with the shortest definitively known reign was Edgar the Ætheling who ruled for 2 months, 12 days in 1066 before submitting to William the Conqueror. Some records indicate that Sweyn Forkbeard reigned for only 40 days in 1013–4.

Elizabeth I holds the records for the shortest tenure of an English heir presumptive (almost 2 years as heir-presumptive to Henry VIII) unless one recognizes the 13-day tenure attributed to Lady Jane Grey's sister, The Lady Herbert of Cardiff. This would also be the record for shortest total tenure as heir-presumptive (Elizabeth was later heiress-presumptive to her sister Mary).
The shortest total tenure as a male heir-presumptive was George I (54 days).
The shortest tenure as a female heir presumptive Mary, Queen of Scots who was heir presumptive from birth until her accession to the throne at the age of 6 days.

### Pretenders in power

During the Middle Ages and the mid-18th century, a number of pretenders to the throne controlled all or a substantial portion of England and Scotland:
* Empress Matilda: Daughter and only surviving child of Henry I of England, was declared her father's heir, but her cousin Stephen usurped the throne. This led to a years long war, in which her son Henry II, was eventually declared Stephen's heir. This period is known as the Anarchy.
* Henry the Young King, who was crowned junior king in 1170 at the age of 15, led a revolt against his father Henry II for several months in 1173–74 and controlled much of England.
* Louis VIII of France: Controlled the Southeast of England and later the whole country briefly during the First Barons' War from 1215 to 1217.
* Edward Balliol was crowned king of Scotland in 1332 and was able to control some parts of it until 1356. His claim was recognized and supported by England.
* James III and VIII sent his son Bonnie Prince Charlie to reclaim his kingdom and the latter controlled Scotland and Northern England for several months in 1745.

## Physical attributes
### Tallest

The tallest measured British monarch was Edward IV, whose skeleton measures 6 ft 4½ in (1.94m). Records indicate that when fully clad in armour he would have been about 6 ft 7 in (2.01 m), an exceptional height for any man, especially of that time.
Both Edward Longshanks and Richard the Lionheart were over six feet (1.83m) tall, which although tall for the general population was not unusual among the aristocracy - although contrary to popular belief, 'Longshanks' was not called that due to the length of his legs, but his arms; they were just under a yard long (91 cm), though there is no evidence to suggest they were particularly disproportionate to the rest of his body.
The tallest queens were Mary, Queen of Scots and Mary II of England and Scotland, who were both 5 ft 11 in (1.80 m).

### Shortest

The shortest British monarch in adulthood was most likely Queen Victoria, who stood only 5 ft 0 in (1.52 m) when in her 30s, and was possibly an inch or two shorter towards the end of her life. The shortest king in adulthood whose height is documented was Charles I, who stood 5 ft 4 in (1.63 m).
