About Tsubo

A tsubo (坪) is the traditional Japanese unit of floor area, equal to 400/121 m² (approximately 3.306 m²) - defined as the footprint of two tatami mats placed side by side. It has been the standard for measuring rooms and apartments in Japan for centuries and remains widely used in real estate and architecture today. Apartment sizes in Japan are routinely quoted in tsubo alongside square meters. One tsubo equals approximately 35.58 square feet or 3.95 square yards.

About Square Yards

A square yard (yd²) is an imperial unit of area equal to a square with sides of one yard (3 ft × 3 ft or 9 ft²). It is commonly used for measuring carpet, fabric, and concrete in construction projects. A queen-size mattress covers about 5 yd², and a typical driveway might require 30-50 yd² of concrete. This unit is particularly common in the textile, carpeting, and landscaping industries in imperial-system countries.
