The Weissmies is located on the main Alpine chain, on a massif separating the Saastal valley on the west and Simplon valley on the east.
The massif consists of two other main summits lying to the north at almost the same altitude, the Lagginhorn and Fletschhorn.
The mountain lies between the Lagginjoch (3,500 m) to the north and the Zwischbergen Pass (3,260 m) to the south.

The Weissmies is one of the 10 four-thousanders surrounding the Saastal, facing the Dom on the west, the third highest summit of the Alps.
