Design by Zag is a design studio based in Glasgow, Scotland.

We specialise in design for print, screen and spaces. Our design approach merges meticulous research with creative thinking. We craft identities, books, way finding, websites, signage, typography, exhibitions and objects for both our clients and ourselves.

Design by Zag is run by Kat Loudon and Kirsty Geddes.
