A suspension holder and a frame unit thereof are provided. The frame unit includes a main segment, a suspension segment, and a holding segment. The main segment is in an elongated shape defining a longitudinal direction. The main segment includes a selecting portion, two long lateral edges, a first mating portion, and a second mating portion, the latter two of which are spaced apart from the selecting portion along the longitudinal direction. The suspension segment and the holding segment extend from the two long lateral edges of the main segment, respectively. The selecting portion selectively geometrically corresponds with the first mating portion or the second mating portion.
