Where it sits
Among the 14 vehicles & ships on this page USS Nimitz ranks 4th from the top by size. The largest in the group is Emma Maersk at 397 m, which is 1.19× the size of USS Nimitz, while the smallest, Tesla Model 3, is 4.69 m.
Stand an adult of 1.7 m beside it and the ratio is 196×: you would need 195 people stacked head to foot to match its size.

A football pitch is about 105 m long. USS Nimitz is 3.17× that, which puts it at 3.2 pitch lengths from end to end.
Walking at an easy 1.4 m/s you cover 333 m in 4 minutes. A jet at 900 km/h covers it in 1.3 seconds.
Next to its neighbours in size
The nearest thing larger than it in this collection is Queen Mary 2 at 345 m (1,132 ft), 1.04× the size. Both figures are the same kind of measurement, so the gap is a fair one.
The nearest thing smaller is Eiffel Tower at 330 m (1,083 ft), so USS Nimitz is 1.01× as big as it. They come from different groups — buildings & towers against vehicles & ships — which is what makes the pairing interesting.
Against fixed yardsticks
Against three fixed yardsticks — USS Nimitz is 1.01× the size of Eiffel Tower (330 m); USS Nimitz is 11.1× the size of blue whale (29.9 m); Earth (12,742 km) is 38,287× the size of USS Nimitz.
How this figure was taken
Vehicles are listed by overall length. Rockets are the exception and are given as full stack height standing on the pad. Everything is drawn standing upright so one scale holds.
How the sizes are taken. Each figure says what it measures — height, length, diameter or elevation — and for which individual or convention. Everything is drawn standing upright on one baseline so a single scale holds, including things that are long rather than tall. Values come from the linked Wikipedia article for each item.
