Measure exterior walls, gables, lower foundation sections, and other paintable surfaces in square feet. Assign windows and doors to specific surfaces and subtract only the openings you choose.
Job Reference
Optional details for print, CSV export, and saved exterior measurements.
Exterior Surface Measurements
Add each elevation or separately measured exterior surface as its own line. Length fields accept decimal feet or feet-and-inches, such as 12.5 or 12' 6".
Gable Wall: rectangle to the eave plus the triangle above. Trapezoid: width × average of left and right heights. Foundation or lower-wall areas can be tracked separately.
Windows, Doors & Other Openings
Assign each opening to a specific exterior surface. Choose whether each opening should be subtracted from that surface.
Returns, trim bands, sills, soffits, and other additional surfaces are not calculated automatically. Add them as separate exterior surfaces using Direct Area when needed.
