A vertical curtain includes a track having two ends each provided with a plurality of support brackets juxtaposed to each other, and two drawing blocks movably mounted on the two ends of the track and connected to one of the support brackets to push the support brackets. Each of the support brackets is movably mounted on the track and provided with a slide member, a fastening member, a limit member and a stop member. Thus, the slide member has a plurality of passages having different positions for mounting the vertical slats so that the track can be used to combine with multiple vertical slats, and the vertical curtain is available for windows having larger sizes, thereby enhancing the versatility of the vertical curtain.
