How big is it, really?
The Britannia's length overall, against things you already know the size of.
The 747-8 held the longest-airliner record for over a decade, until Boeing's 777-9 took it by about 19 inches (76.72 m) — our sibling site aircraft.fyi measures everything that flies the same way.
One Britannia = 1.23 Titanics · 3.1 football pitches · 13 blue whales · 4.3 Boeing 747-8s laid end to end.

What makes it different
Britannia was P&O's flagship for six years and is still described that way by the line, even though Iona and Arvia are both around 40,000 gross tons larger. She was named at Southampton in March 2015 by Queen Elizabeth II — the last ship the Queen ever christened.
She is a Royal-class ship, the same Fincantieri hull as Princess Cruises' Royal, Regal, Majestic, Sky, Enchanted and Discovery — the most reproduced design in Carnival Corporation's portfolio. The British-market fit-out is what differs: a large outdoor promenade, UK-sourced spirits, and dining programmes built around British chefs.
One structural oddity sets her apart from her fleetmates: she has no ocean-view cabins with fixed windows at all. Accommodation is inside or balcony, with nothing in between — a decision no other P&O ship repeats.
