To measure the bay do the following:  This example is for the typical bay window— window left, a bend, window center, a bend, & window right.

Starting at the left, measure the left window width to the first bend, then measure from bend to bend, lastly measure the second bend across the width of the right window, add 1”-4” for the overhang on each side. Now add these 3 measurements together and subtract 32” for the bay pieces. What is left over is the length of cornice you need to purchase from the 9”, 12” ,or 15” valance styles pages, plus 2 bay/corner pieces from the chart above.

Left panel=43”, center= 77”, right panel=43”

Total = 163 + 4 = 167 - 32 = 135

Purchase 2 bay pieces and the Up to 144” straight cornice.
