Three-bedroom apartment floor plan: size, layout & how to measure it

80–140 m²

3 bedrooms, often 2 bathrooms
layout

Family-sized apartments run about 80–140 m² with three bedrooms and frequently a second bathroom or en-suite — meaning more thresholds, more transitions, and more places for a quote to leak.

What the layout looks like

A master en-suite adds a wet-area threshold inside a bedroom; utility or laundry nooks add small polygons that are easy to forget. In many markets these units also carry a balcony plus an air-conditioner ledge or service area that must stay out of the internal floor total.

Measuring it accurately

The reliable way to measure any 3-bedroom plan is off the drawing itself: calibrate against a printed dimension line, then trace each room along the inside face of the walls. Count the bathroom thresholds explicitly — each one is a transition profile in the quote. Perimeter view gives you per-room skirting runs so the second bathroom does not get absorbed invisibly into a lump sum.

PlanTape does the tracing for you — AI 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.
