Here is a good site where you can see the difference in size between carriers of France, US and UK.
www.stoatys.net...
Carrier nearest top is a Nimitz Class of the USA (USS John C Stennis)
Carrier below that on left is FS Charles de Gaulle from France
Carrier bottom right is the USS John F Kennedy
and the smallest carrier (behind Charles de Gaulle) is the Royal Navy's HMS Ocean which is not a fixed wing carrier but a helicopter carrier.
Despite being the smallest carrier there, it is still bigger than any of the Invincible Class.
