The councillors are elected in provincial constituencies by proportional representation using the D'Hondt method.

In this system parties are grouped in alliances, supporting a candidate for the post of President of Tuscany.

The candidate receiving at least 40% of the votes is elected to the post and his/her list (or the coalition) is awarded a majority in the Regional Council.

The winning candidate is assured a majority in the Regional Council.

[2] According to the official 2011 Italian census, the 40 Council seats which must be covered by proportional representation are so distributed between Tuscan provinces.
