A papermakers fabric and method of designing and manufacturing same which exhibits high tolerance to temperature and/or moisture variation and as a result, retains dimensional stability avoiding these problems. A specific fabric construction is selected having a defined machine direction (MD) and cross machine direction (CMD) yarn components. A mathematical model of the selected fabric structure is then defined in terms of the dimensions of the yarn components in relationship to the machine direction length of the fabric. The percent change in fabric length is then determined as a function of both the dimensions and the expansion characteristics of the MD and CMD yarns. The fabric is then designed to have calculated expansion characteristics within selected tolerances. -34-
