A triple layer papermaking fabric having top and bottom fabric layers joined by a binder yarn, the top fabric layer including machine direction and cross machine direction yarns interwoven in a plain weave having an open area determined by the formula: (1 - Nc x Dc) x (1 - Nm x Dm) x 100 where Nc = number of Cross Machine Direction yarns per inch Nm = number of Machine Direction yarns per inch Dc = diameter of Cross Machine Direction yarns Dm = diameter of Machine Direction yarns The configuration of the papermaking fabric reduces or eliminates density differences in the finished paper sheet produced on it.
