Tatami mat (畳, jō) - Japanese flooring unit of area

Tatami mat is a traditional Japanese flooring module used as a practical unit of area; room sizes are often stated by the count of mats (jō). Dimensions vary regionally, so one tatami has no single national standard.

  • Names/aliases: tatami, 畳 (jō); room size written as “n-jō”
  • System: Traditional Japanese (non-SI)
  • Typical sizes (area):

• Kyōma (Kyoto): 0.955 m × 1.910 m = 1.824 m² ≈ 19.63 ft²

• Chūkyōma (Nagoya): 0.910 m × 1.820 m = 1.656 m² ≈ 17.83 ft²

• Edoma/Kantōma (Tokyo area): 0.880 m × 1.760 m = 1.5488 m² ≈ 16.67 ft²

• Other regional modules exist; common range ≈ 1.55–1.82 m² per mat

  • Room estimates: 6-jō room ≈ 9–11 m² depending on region; 8-jō ≈ 12–15 m²
  • Construction note: buildings often use tatami modules as planning grids; mats are rectangular with length ≈ 2 × width
