The Drywall Quantity Calculator is a specialized tool designed to bridge the gap between gross measurements and actual material requirements. By accounting for structural openings like doors and windows, and applying a customizable waste factor, it provides precise estimates for drywall sheets (4x8, 4x10, 4x12), screws, and joint tape. Use calculate_sheet_quantity to determine sheet counts based on area and openings, estimate_consumables to find hardware needs, or get_opening_constants to see the standard deduction values used in calculations.
