The electoral system uses the D'Hondt method and a closed-list proportional representation, with a minimum threshold of five percent regionally.

Each constituency is entitled to an initial minimum of 20 seats, with the remaining 39—29 until 2007—being distributed in proportion to their populations (provided that the seat-to-population ratio in any given province did not exceed three times that of any other).

The exception was the 1983 election, when each constituency was allocated a fixed number of seats: 29 for Alicante, 25 for Castellón and 35 for Valencia.
