At Timberlane, all shutter styles except Bermuda shutters are priced per pair. To estimate the price for each pair, simply take each window's width and height dimensions based on the directions provided in Measuring Your Windows & Hardware, and find the closest dimensions on the Pricing Guide tables (download PDF) for your preferred shutter style. Then, add costs for any options you have selected for each pair. This quick process should provide you with a fairly accurate estimate.
