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 Pyeong

A pyeong (평) is the traditional Korean unit of floor area, equal to approximately 3.306 m² - historically derived from the Japanese tsubo, with which it shares the same value. Despite South Korea officially adopting square meters, pyeong remains deeply embedded in Korean real estate culture. Apartment listings in Seoul and Busan still commonly advertise sizes in pyeong, and a typical Korean family apartment is around 25-33 pyeong. One pyeong equals approximately 35.58 square feet.
