Multiply the 1-1/2 inch width of the fascia board by the slope of the roof (e.g. 4/12). 1.5” times 4 divided by 12 = 0.5 or ½ inch. For a 2×6 fascia board at a 4/12 slope, the trim size would be 1-1/2 inch x 5 inches for an overhang without a soffit.
You construct fascia boards out of 1-inch lumber. The width depends on the width of the rafters, but since builders generally use two-by-six or two-by-eight lumber for roof construction, the most common dimensions for fascia boards are one-by-six and one-by-eight inches.
