How do I calculate square footage of an irregular room?
For irregular rooms, divide the space into regular rectangles, calculate the square footage of each section, and add them together for the total area.
Should I include closets in square footage calculations?
This depends on your purpose. For real estate listings, typically include closets. For flooring calculations, you might want to exclude them if you're not installing the same flooring in closets.
