We've designed Wrap Buddies to fit most tables. That means any tabletop with at least 3" of overhang (if you slide your fingers along the underside of the tabletop, starting at the edge, you can move them back at least 3 inches before encountering any obstructions, like the table's apron) and with a top thickness that's 1 1/2" or less. In metric, that's 38mm thick with an overhang of at least 25mm. If your table has less overhang, they may still work, but will grip a bit less securely.
