The flag shows a red lion standing out prominently against an even yellow background.

The aspect ratio of the South Holland flag is 2:3, which are the same dimensions that also apply to the national tricolour.

The left-facing lion, standing on its hind legs, occupies three-quarters of the flag's height and is equally distant from the top and bottom.

The decision to adopt the current flag was motivated by a desire to raise the profile of traditional symbolism of Holland.

The current flag closely resembles the cloths used by the counts of the County of Holland since the Crusades.
