Read the area label

A listing should state both the unit and the measurement basis. Carpet area, built-up area, super built-up area and plot area are not interchangeable. Ask the seller or developer for the definition and supporting plan used in that specific quotation. Avoid assuming a fixed conversion percentage between them.

Separate the land from the building

Plot area describes the land parcel. A building can occupy part of that parcel and have more than one floor. Keep the land measurement, floor measurements and outdoor spaces separate in your notes. Check the recorded boundaries with the appropriate professionals when the property is a serious option.

Compare like with like

If one apartment is quoted using carpet area and another using a broader basis, do not rank them by the headline rate per square foot. Ask for comparable measurements and confirm what is included in the quoted price. A lower rate on a different basis is not automatically better value.

Take the plan to the viewing

Use the plan to check room relationships, storage, circulation and furniture fit. Note any difference between the marketing material and what you see. Ask for clarification in writing; a personal measurement is a useful sense check, not a replacement for formal measurement or the agreed documents.
