There are four main bays or gulfs on the White Sea.
These bays connect with the funnel-shaped opening to the Barents Sea via a narrow strait called "Gorlo" (Russian: Горло, meaning "throat").
Kandalaksha Gulf lies in the western part of the White Sea; it is the deepest part of the sea, reaching 340 metres (1,115 feet).
On the south, Onega Bay receives the Onega River.
To the southeast, the Dvina Bay receives the Northern Dvina at the major port of Arkhangelsk.
On the east side of the 'gorlo', opposite to the Kola Peninsula, is Mezen Bay.
It receives the Mezen River and the Kuloy River.
Other major rivers flowing into the sea are the Vyg, Niva, Umba, Varzuga and Ponoy.

The seabed of the central part and Dvina Bay is covered in silt and sand, whereas the bottom of the northern part, the Kandalaksha Gulf and Onega Bay is a mixture of sand and stones.
Ice age deposits often emerge near the sea shores.
Northwestern coasts are tall and rocky but the slope is much weaker at the southeastern side.

The White Sea contains a large number of islands, but most of them are small.
The main island group is the Solovetsky Islands, located almost in the middle of the sea, near the entrance to Onega Bay.
Kiy Island in Onega Bay is significant due to a historic monastery.
Velikiy Island, located close to the shore, is the largest island in the Kandalaksha Gulf.
