Where it sits
Among the 10 mountains on this page Mount Kosciuszko ranks 9th from the top by size. The largest in the group is Mount Everest at 8,848.86 m, which is 3.97× the size of Mount Kosciuszko, while the smallest, Ben Nevis, is 1,345 m.
Stand an adult of 1.7 m beside it and the ratio is 1,311×: you would need 1,310 people stacked head to foot to match its size.
In everyday distances
A football pitch is about 105 m long. Mount Kosciuszko is 21.2× that, which puts it at 21 pitch lengths from end to end.
Climbing is about vertical metres, not horizontal ones: 2,228 m of elevation is 743 storeys of a typical 3 m floor. Even a lift moving at 10 m/s would need 3.7 minutes to cover it.
Next to its neighbours in size
The nearest thing larger than it in this collection is Mount Fuji at 3,776 m (12,388 ft), 1.69× the size. Both figures are the same kind of measurement, so the gap is a fair one.
The nearest thing smaller is Ben Nevis at 1,345 m (4,413 ft), so Mount Kosciuszko is 1.66× as big as it. They sit in the same group.
Against fixed yardsticks
Against three fixed yardsticks — Mount Kosciuszko is 6.75× the size of Eiffel Tower (330 m); Mount Kosciuszko is 74.5× the size of blue whale (29.9 m); Earth (12,742 km) is 5,719× the size of Mount Kosciuszko.
How this figure was taken
Elevation is measured from mean sea level to the summit, not from the base of the mountain. Surveys are revised, so a figure here can differ from an older atlas by a few metres.
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.
