How much wider is Switzerland than the Grand Canyon National Park?
Switzerland measures 345.9 km (215 mi) east to west, and the Grand Canyon National Park measures 210 km (130.5 mi) east to west. The Grand Canyon National Park would have to grow by 65% to match Switzerland, which is 1.65 times its east-west span. Put the other way round, the Grand Canyon National Park covers 61% of Switzerland on the axis both are judged on. Switzerland and the Grand Canyon National Park are both written in hundreds of kilometres, and the 65% between them is the whole of the difference.
| Object | Real size | Axis measured | What the figure covers |
|---|---|---|---|
| Switzerland | 345.9 km 215 mi |
East-west span | Widest extent of the outline on that axis |
| Grand Canyon National Park | 210 km 130.5 mi |
East-west span | Widest extent of the outline on that axis |
Both figures, Switzerland and Grand Canyon National Park, come from the Size It Up measurement set, one real-world size and one measured axis per object, last checked in September 2026; outline provenance is listed on the sources page.
Why this one is hard to judge by eye
The outline of Switzerland that most people carry comes from a world map, and every projection that keeps angles true stretches whatever sits far from the equator; the outline of the Grand Canyon National Park above is scaled from measured distances instead.
What each figure covers
Switzerland. Switzerland is measured east to west. Road distances across it are far longer than the span suggests, because almost nothing there crosses in a straight line.
Grand Canyon National Park. The park is measured east to west, along the canyon. The canyon itself is over a mile deep, which is the dimension no outline can show.
Switzerland and the Grand Canyon National Park are both quoted as an east-west span, which is what makes the ratio above a like-for-like figure.
What else is about that size?
Measured the same way, Switzerland at 345.9 km sits within a tenth of Great Bear Lake at 342.5 km and Costa Rica at 370.5 km. Grand Canyon National Park at 210 km has Cyprus at 210.4 km and Greater Tokyo Area at 194.6 km for company, within a tenth. Swapping any of those in for Switzerland would move its ratio to the Grand Canyon National Park by less than 10%.
