The narrowest Chartpak Tape available is 1/16" , you could buy it wider but I'm not sure how you would cut it . I can tell you that it will bend for gradual curves but nothing drastic , if you want small radius bends then buy the Crepe Chartpak Tape , the crepe tape bends very easily and stays put ! Only downside is it's thickness and it doesn't have a smooth finish , it's cheap enough you can buy a roll and test it yourself .
Here's a link to Amazon . I bought both the Blk Crepe and Blk Gloss to compare them .
