The official blazon is "Azure, three fusils in fess argent" (Norwegian: I blått tre sølv spisruter).

This means the arms have a blue field (background) and the charge is a set of three fusils lined up horizontally.

The charge has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used.

[10][11] The Brudavoll Farm, part of the Sunnmøre Museum Foundation, is located about 5 km (3.1 mi) from the village of Ørsta.

Apart from the mountains, Ørsta's dominant geographical feature is fjords: Storfjorden in the north, Vartdalsfjorden, Ørstafjorden in the west, and Hjørundfjorden in the east.

Otherwise, it borders the municipalities of Sula in the north, Hareid and Ulstein (by sea only) in the west, Sykkylven to the northeast, and Stranda to the southeast.

Important sectors are mechanical industry and furniture manufacturing, agriculture, commercial fishing, and aquaculture.

On the other hand, the northern part of the municipality has strong maritime traditions, with Vartdal being the home of one of the largest factory trawler fleets in Norway.
