Frequently Asked Questions
Tatami (畳) are traditional Japanese mats used as a flooring material. They are typically made of woven rush grass around a straw core and are uniform in size within specific regions.
Tatami sizes vary by region in Japan, reflecting historical architectural standards. For example, Kyo-ma is prevalent in Kyoto, Edo-ma in Tokyo, and Chuukyo-ma in the Nagoya region. These differences influenced traditional room construction.
This calculator primarily focuses on fitting full-sized tatami mats to determine the maximum coverage and any significant leftover space. While half tatami mats (hanjō) are used in practice, this tool simplifies the calculation for full mats.
