For elections to Danish municipalities, a number varying from 9 to 31 are chosen to be elected to the municipal council. The seats are then allocated using the D'Hondt method and a closed list proportional representation.
Lyngby-Taarbæk Municipality had 21 seats in 2021
Unlike in Danish General Elections, in elections to municipal councils, electoral alliances are allowed.
