Introduction
Carpet area is the usable floor area inside a home where a carpet could be laid, measured to the inner faces of enclosing walls under the applicable definition. Built-up area generally adds the thickness of walls and may include balconies or other attached spaces. Super built-up area is a marketing and allocation measure that can add a proportionate share of common areas.
Plan with verified information
These numbers are not interchangeable. Flooring, furniture and room planning normally depend on clear internal dimensions. Paint and plaster estimates depend on wall surface area. A property comparison may use carpet area, while a contractor's quotation may refer to built-up area. Always ask what is included and request a marked drawing.
Convert quantities into buying decisions
For a reliable calculation, divide an irregular plan into simple rectangles, calculate each part and add them together. Keep ducts, shafts, voids, balconies and wall thickness in separate rows. Do not assume a fixed conversion percentage because building design, wall thickness and common-area allocation vary.
Keep a transparent project record
Before purchase or construction, reconcile the advertised figure with the sanctioned plan, agreement and the measurement method required by applicable law. The purpose of an area calculator is to make dimensions understandable; legal ownership and structural decisions still require approved documents and qualified professionals.
