Sources give about 12-16 lb (roughly 5.4-7 kg); the UK breed page lists 5.67 kg for bucks.
normal fur, medium length; large, powerful body
A big, strong rabbit with a long, flat back, broad shoulders and hindquarters, sturdy legs and tall upright ears. Its coat is soft, dense and of medium length.13
A friendly, easygoing rabbit that would rather lounge than race around. Like its Flemish Giant ancestors it is known for being gentle and tolerant, which makes it a pleasant companion for families who have room for a large rabbit.34
Low to moderate energy. It still needs daily time in a large, safe area to stretch, hop and keep fit.45
Regular brushing keeps the dense coat tidy and helps during moults; check nails routinely. Support the whole body when lifting a rabbit this heavy.4
Welfare guidance asks for a combined shelter and exercise area of at least 3 m x 2 m x 1 m high for a pair of medium rabbits, tall enough to stand up on the back legs and long enough to stretch out fully. Breed guides suggest a giant like this needs at least about 20 sq ft (roughly 1.9 m2) of its own, often a shed with a run or a dedicated room.54
Unlimited hay or grass should form the bulk of the diet, with fresh water always available, plus some leafy greens and a small measured portion of pellets.54
A sociable animal that should share its home with at least one compatible rabbit, plus regular gentle time with people.5
British breeders wanted a giant rabbit in more colours than the steel grey allowed for the British Flemish Giant, so they worked with coloured Flemish Giants brought over from America in the late 1940s. Richard Kirk is credited with creating the first British Giants, which were shown at Alexandra Palace in the early 1960s, although some sources date its recognition as a separate breed to the 1940s.213
It is the largest of the rabbit breeds that were developed in Britain.1
Some British Giants grow as big as a small dog.1
The breed exists largely because the British Flemish Giant standard only allows one colour, steel grey.1
The first British Giants made their show debut at Alexandra Palace in London.2
