A stereo slide mount system that can reproduce an accurate stereo effect to facilitate a mounting operation and accurate positioning. A transverse or vertical alignment or positioning guide is used to position the stereo slide film in combination with longitudinal positioning pins. In one embodiment, the vertical positioning guide comprises a plurality of pins, and in another embodiment a plurality of raised edges. A set of plural types of stereo slide mounts 1 (#0 to #n) in which the width W of windows stepwisely decreases with each mount having the same window pitch Pw and different window widths W. A base frame is provided with positioning pins for engaging perforations on the film, and a cover frame is provided with pin holes to be engaged with the positioning pins. The positioning pins and the pin holes are provided at positions such that the inner vertical edges of the windows are brought into agreement with the inner edges of the pictures of the film. The stereo slide mount having smaller width windows has an increased gap width (P0, P1, P2, . . . ) between the two sets of right and left positioning pins so as to extend the pitch of the right and left films, and therefore the outer masking amount of the right and left films increases.
