Where it sits
Among the 23 buildings & towers on this page Christ the Redeemer ranks 23rd from the top by size. The largest in the group is Burj Khalifa at 828 m, which is 27.6× the size of Christ the Redeemer.
Stand an adult of 1.7 m beside it and the ratio is 17.6×: you would need 17 people stacked head to foot to match its size.
In everyday distances
It fits inside a football pitch 3.5 times over — a pitch is about 105 m and Christ the Redeemer is only 30 m.
Walking at an easy 1.4 m/s you cover 30 m in 21 seconds. A jet at 900 km/h covers it in 120 milliseconds.
Next to its neighbours in size
The nearest thing larger than it in this collection is Space Shuttle orbiter at 37.2 m (122 ft), 1.24× the size. Note the two figures are not the same measurement: for Christ the Redeemer it is height, for Space Shuttle orbiter it is length.
The nearest thing smaller is blue whale at 29.9 m (98.1 ft), so Christ the Redeemer is 1× as big as it. They come from different groups — animals against buildings & towers — which is what makes the pairing interesting.
Against fixed yardsticks
Against three fixed yardsticks — Eiffel Tower (330 m) is 11× the size of Christ the Redeemer; Christ the Redeemer is 1× the size of blue whale (29.9 m); Earth (12,742 km) is 424,733× the size of Christ the Redeemer.
How this figure was taken
Building heights depend on the rule used: architectural height counts spires but not antennas, tip height counts everything. The basis is named with each figure.
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.
