A pyeong(or pronounced as tsubo in Japanese, [píng], [ㄆㄧㄥˊ] in Chinese) is a unit of the size of rooms or buildings in Korea, Japan, China and Taiwan equal to ⁴⁰⁰⁄₁₂₁ square metres (3.3058 m², 3.954 sq yd or 35.586 sq ft) and with the same symbolic word "坪". A studio apartment will generally be around 10 to 15 pyeong, a house somewhere around 50 or more, and the smallest of rooms, consisting of only a bed and a bit of floor space for students, will be as little as 1.5 pyeong.

Anecdotally, the unit was derived from the amount of space an average sized man would take up lying on the floor with his arms and legs spread out.^{[citation needed]}

One pyeong consists of 36 square ja.

In South Korea, A new law enacted as of July 1, 2007 will replace the use of pyeong in official documents with the square metre.

In Japan, tsubo(pyeong) is exactly the area of 2 blocks of the standard Tatami putting together into a square since the Edo Period(江戸時代).

In Taiwan, since Taiwan was once a colony under Japanese rule before today's Republic of China, ping(pyeong) is still commonly used despite the standard measurement of area has been changed to square metres in 1945.
