These formulasapply for both horizontal and vertical : When Estimating for a large project, you maywant to add a waste allowance of 10 percent to thetotals for siding, soffit and wall surfacesMeasure height (excluding gables). Measure width (including doors and windows)._____ x _____ = _____(height) (width) (surface area)Repeat for remaining gable end surfacesMeasure height at center (add 1' to allow for waste). Measure width and divide by x _____ = _____(height) (1/2 width) (surface area)Repeat for remaining wall of gambrel houseDivide the upper wall of a gambrel house as shown inthe illustration.

3 Measurewidth of x _____ = _____(length) (width) (surface area)MeasuringBefore ordering accessories, you also have to determinethe width of the J-channel into which you will fit the vinylsiding. To do this, you must first determine which of twomethods you will use to apply sheathings orunderlayments. This is covered in more detail under Sheathings. Starter strip: Measure along base of : For siding installations, measure around doors and windows, under eaves, at rake edges of gables where dormer meets roofline, and anywhere else required to provide a finished soffit, measure along wall under eave and along fascia porch ceilings, measure along perimeter of the porch : For soffit, measure along wall under porch ceilings, measure along perimeter of the porch " and 5" lineals: For casing, measure along perimeter of doors and windows.
