Room Floor Area Calculators

• Area of Room's Floor - Area of Floor in Rectangular Room
• Area of Room's Floor with Angled Bump-out - Area of Floor in Rectangular Room with Angled Bump-out
• Area of Room's Floor with Squared Bump-out - Area of Floor in Rectangular Room with Squared Bump-out

Most rooms are  simple rectangles with a length and a width.  The only common departure are rooms with bump-outs.  Some bump-outs are angular and taper down from an opening.  Some bump-outs have squared corners.  To compute the square feet of these floors are simple geometry based on the measurements of the main floor and the bump-out dimensions.

To compute the area of a floor with a different shape (e.g., circular, oval, or polygon), see the Area Calculator.
