Massachusetts is in Climate Zone 5 - Cool-Humid/Cold (significant heating, moderate cooling). Homes here typically have higher heating demands than cooling.
Proper siding calculation involves several steps:

Divide by 100. If you have 2,000 square feet of siding, that's 20 squares. Most vinyl siding cartons cover 2 squares (200 sq ft) each.
10% is standard for rectangular homes with few openings. Use 15% for homes with many windows, complex corners, or gables. Use 20% for very complex architecture.
