The 1.1-square-kilometre (0.42 sq mi) island is located 2 kilometres (1.2 mi) northeast of the large island of Vågsøy in the Sildagapet bay and about 2.5 kilometres (1.6 mi) west of the island of Barmøya.

Silda sits about 2 kilometres (1.2 mi) east of the small village of Langenes and about 3 kilometres (1.9 mi) northeast of Raudeberg, both on the island of Vågsøy.

In 2014, there were 12 inhabitants on the island, which is only accessible by boat.

[1] The name of the island comes from the Norwegian language word sild which means herring, since herring fishing has been important in the region for centuries.
