<p>Many sources state that the Bay of Fundy has the largest vertical tidal range. The horizontal range is also very large (up to 5 km according to this website: <a href="https://fundyforce.ca/learning-portal/tides" rel="noreferrer">https://fundyforce.ca/learning-portal/tides</a>). Is this the largest horizontal tidal range in the world?</p>

The [Wadden Sea](https://en.wikipedia.org/wiki/Wadden_Sea) in the German Bight of the North Sea from Danmark in the North to the Netherlands in the South-West has probably the largest horizontal range of the tides by quite some margin; The tidal area is there up to 20 ... 40km wide (depending on how you measure):

Wikipedia has a list of [tidal flats](https://en.wikipedia.org/wiki/Mudflat), and there are other significant ones, but they seem to be slightly-steeper-sloped so that they are often not as wide.
