These styles may change with a new monarch, or by a degree, parliament vote, or law change.
For each category, we give the usual style used by the current member of that category. Although, not everyone in that group may have that style. Exceptions include:
(1) Heir Apparents are either HRH Crown Prince/ss or are HRH Prince/ss and have a special title to denote they are the heir.
- Family members with a different style due to their marriage (or parents/grandparents' marriage) into another Royal House.
- Family Members who lost their style due to an unapproved marriage. (More common in the older generations when marriages were required to be “equal.”)
- Family members who agreed not to use a title/style for themselves or their children.
- Family members down the female line may be styled differently than family members down the male line (especially in the older generations).

(2) Prince Harry, Duchess Meghan, and Prince Andrew agreed to no longer use their HRH, but it has not technically been removed.
(3) Some Family members lost their HRH due to unequal marriages (E.g. marrying a non-Royal). Rules like this have been removed in subsequent generations.
(6) Looking at the decendants of Prince Gustaf Adolf, instead of the previous monarch King Gustaf V, as succession skipped a generation, due to the Prince’s early death.
(7) As children traditionally get their titles from their father, only children of sons of the Monarch are HRH Prince/ss. Although some have chosen not to style their children that way to give them a more private life. Children of daughters get no style from their mother and instead would be styled appropriately as children of their father.
(8) The people in this category get their Style by virtue of their parents' or grandparents' marriage into another Royal House.
