3-room HDB flat floor plan: size, layout & how to measure it

60–65 m²
typical internal floor area (≈650–700 sq ft)
2 bedrooms
layout

A staple of older Singapore estates like Toa Payoh, Ang Mo Kio and Bedok, typically 60–65 m² with two bedrooms, a very common size for skirting and flooring repackaging jobs.

What the layout looks like

Older 3-room blocks (New Flat / Improved / Model A variants) differ meaningfully: corridor-facing units often have a long access balcony, and improved layouts add a separate WC and bathroom. Many pre-1980s plans have rougher linework, so automatic tracing saves the most time on these.

Measuring it accurately

The reliable way to measure any 3-room hdb plan is off the drawing itself: calibrate against a printed dimension line, then trace each room along the inside face of the walls. On corridor-type plans, the ACCESS BALCONY strip is common property; include it only if the quote covers it. Check whether the plan marks "ROUGH FLR. FIN." rooms, since those often need levelling allowances in the quote.

PlanTape does the tracing for you. It detects every labelled room and the scale line in under two minutes, you fine-tune the corners, and the per-room areas and skirting perimeters export as a CSV — in square metres and metres.
