The answer

1. 1Panama Canal82 km
2. 2Volga-Don Canal101 km
3. 3Suez Canal193 km
4. 4Grand Canal of China1,776 km

Why this order

Ranked shortest to longest, Panama Canal (82 km) goes at the top and Grand Canal of China (1,776 km) at the bottom.

The closest call is Panama Canal (82 km) against Volga-Don Canal (101 km), only about 23% apart. That is the swap most likely to cost a point.

The biggest gap is between Suez Canal and Grand Canal of China, about 9.2 times apart, so that boundary should be the easiest part of the order to get right.

From top to bottom the figures span a factor of roughly 22.
