How wide is the Thames at its widest?

Answer 1

The width of the River Thames averages around 18 meters near the rise or start.

The width of the river Thames increases the further downstream you go.

Lechlade 18 metres wide

Oxford 76 metres wide

Teddington 100 metres wide

London Bridge 265 metres wide

Woolwich 448 metres wide

Gravesend 732 metres wide

Nore Light, 10 km wide

Estuary (between Shoeburyness and Sheerness) 8 km wide

Whitstable and Foulness Point, the estuary is 29 km across.

Westminster bridge, just in front of the Houses of Parliament, is 826.8 ft (252m) wide, which is a fairly good indication of the width of the river at the point most visitors would see it. A few miles upstream, at Hammersmith, the bridge is only 700 ft (210m), whilst at Dartford, the last bridge on the Thames before the open sea, the bridge is 2,664 ft (812m) long.

Answer 2

The width and depth varies widely throughout its length.

The entire river from Cricklade to Teddington can be punted with a 20 foot pole (under 6 metres). There are of course some sections where the greatest depth exceeds this.

The minimum depth from Richmond to Teddington (half tidal) is 1.72 metres.

Answer 3

The width of any river, including the Thames, will vary greatly according to which part of the river you are visiting. The mouth or estuary of a river will obviously be much wider than the part of the river near its source.

Answer 4

The width of the Thames River varies. The widest part of this river is 18 miles and it is 215 miles long.
