A stereo slide mount can reproduce an accurate stereo effect to facilitate easiness of mounting operation and accurate positioning. Plural types of stereo slide mounts 1 (#1 to #n) that widths W of windows stepwisely decrease have the same pitch Pw of the windows and different width W of the windows and fitting pitches of right and left films. A base film is provided with a positioning pin 6 for engaging perforations of the film, and a cover frame is provided with pin holes 7 to be engaged with the positioning pins 6. The positioning pins 6 and the pin holes 7 are provided at positions that the inner vertical sides of the windows are brought into agreement with the inner edges of the pictures of the film. The stereo slide mount having smaller widths of the windows increases gap width (P0, P1, P2, . . . ) between two sets of right and left positioning pins 6 to extend the pitches of the right and left films, and the outer masking amounts of the right and left films increase.
