Measure the entire shape of a curved shower rod if this is the style you have. Expect the measured width to be approximately 6 inches more than a standard curtain rod. Purchase a shower curtain with a 72-inch width, if available, to compensate for the additional width. If necessary, a 70-inch curtain width works as well. This is because the rods curve inward at the edges, making for an overall smaller width measurement.
