How do I calculate square footage of an irregular room?

Split the space into rectangles, calculate each one, and add them together. Subtract large permanent obstacles like islands.

Should I add waste to square footage?

Not to the measurement itself. Add waste later at the material stage — usually 10% for flooring and tile.

144 square feet — 12 ft × 12 ft.
