The Metropolitan Borough of Calderdale was formed by the amalgamation of the County Borough of Halifax, the Borough of Brighouse, the Borough of Todmorden, the Elland Urban District, the Hebden Royd Urban District, the Ripponden Urban District, the Sowerby Bridge Urban District and part of the Queensbury and Shelf Urban District.
 
The green shield with its blue wave represents the River Calder and its valley. The Paschal Lamb, derived from the crest of the County Borough of Halifax, is the emblem of St. John the Baptist and of the wool industry. The white rose represents Yorkshire.
The mural crown is a familiar emblem for a civic authority, made of the characteristic local stone, from which rise nine white roses joined on a single stem, representing the union of the nine former Yorkshire areas in one authority.
The gold lions were the supporters of Halifax, and one was the main charge in the arms of the Borough of Brighouse, from which are also taken the black crescents held in the lion's paws. Each lion is collared with a wave of blue like that in the arms of the Borough of Todmorden shield, where it alluded to the Calder.
The motto refers to the special aptitudes of Calderdale, not only in woollen manufacture, but in all kinds of other trades and activities carried on in the area, including the pursuit of the arts.
