If you mean the length from its source - it's 346 km (215 miles) long
The Thames Tunnel is 1,300 feet (396 meters) long.
The Thames' length is 346,010 meters.
The Thames elevation is 110 meters, 361ft.

The Millennium Bridge in London, UK is 10.8m above the river Thames at high tide.
As it flows through central London the Thames is surprisingly shallow. Underneath Westminster bridge the depth is usually no greater than 6 feet i.e. about the depth of a tall person. However the river does rise considerably with the Spring tides, so its depth varies. Obviously the Thames estuary is far deeper, I think the maximum depth being around 30 feet. I wouldn't recommend trying to find out yourself unless you have scuba diving equipment and are a trained drift diver LOL Kate
The width of the River Thames varies significantly along its course, but at its narrowest point, known as the Thames Barrier, it measures approximately 520 meters (about 1,706 feet) wide. However, the river can be much wider in other areas, reaching widths of over a kilometer in some places. The Thames also narrows at various points, such as in the stretch around Henley-on-Thames, where it can be less than 30 meters in certain spots.
110 metres (360ft) at its source at Kemble in Gloucesterhire.
Hundreds, the Thames is a long river and flows through many towns and villages. There are 107 bridges from source to the Thames mouth
The Seine River, which flows through Paris, has an average width of about 24 to 30 meters (79 to 98 feet) in the city, while the Thames River in London averages around 250 meters (820 feet) at its widest point. Therefore, the Thames is significantly wider than the Seine. Additionally, the Thames has a more extensive river system, which contributes to its greater overall width.
