Colonial house floor plan: size, layout & how to measure it

1,500–3,000 sq ft
typical internal floor area (139–279 m²)
3–4 bedrooms over 2 stories
layout

Colonials run about 1,500–3,000 sq ft over two full stories: living spaces down, bedrooms up. Two drawings per house means double the measuring, and a stair opening to keep out of the upstairs total.

What the layout looks like

The first floor typically holds a foyer, living room, dining room and kitchen, often with a half bath; three to four bedrooms sit upstairs around a central hall. The stairwell and its void must stay out of the second-floor area, and a tiled foyer meeting hardwood adds threshold lines a lump-sum quote misses.

Measuring it accurately

The reliable way to measure any colonial plan is off the drawing itself: calibrate against a printed dimension line, then trace each room along the inside face of the walls. Measure each story as its own plan and keep the stair opening out of the upstairs polygons. Price the foyer separately when it takes a different finish; the CSV gives each room its own line either way.

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 baseboard perimeters export as a CSV — in square feet and feet.
