/ standard measures
 Japanese term or phrase: 畳数 A standard measure for house size in Jpn. What do you think of translating it just as "area," or would you put something like "(measured in tatami mats)" next to it? Anyhoo, thanks as always for your help!

Number of tatami mats

Explanation:
Rooms are commonly described as 6-mat, eight-mat or whatever
e.g. six-mat room or six-tatami room.

Typically 0.9m x 1.8m = 1.62m2, although there are variations.

For the area of a whole house just ¥"floor area¥" would be reasonable.

Tsubo is more common for the whole area of a building, and for land, as Nakamura says, but in this case the area for the building seems to be in jou, not tsubo (1坪=2畳）.

 Thanks very much!

agree  Hidenori Nakamura: 部屋 ⇒ XX畳、 建物 → floor area of YY "tsubo（坪）"

-> Good point, see above

agree  Kaori Myatt: Yes!
 31 mins
-> Thanks

agree  Philip Ronan: 畳数 can also be used for Western-style rooms without mats, so you might want to say something like "equivalent to ‾ tatami mats".
 1 hr
-> True, like 洋室７．５畳

agree  Shinya Ono: Impressive　and expansive
 4 hrs

number of tatami mats [tatamis, tatami's]

Explanation:
"Tatami", as well as "futon", is now being accepted in English. See some 900+ examples of "tatami" found in English pages. Click the link below. The plural form of "tatami" is "tatamis" or "tatami's", though I guess the former may be preferred.

For actual representations of the size of room, you may use "tatami mat" too. "四畳半の部屋" is either "four-and-a-half-tatami-mat room", "four-and-a-half-tatami room", or "four-and-a-half-mat room". All of these are found in Google:

As you may know, there still exist many people who do not understand the notion of "tatami" or "joo". For them, you may add a square feet notation or a square meter notation. For example, "四畳半の部屋" can be "a four-and-a-half-tatami-mat room (14.58 square meters)" or "a four-and-a-half-tatami-mat room (approx. 157 square feet)".

For ¥"四畳半の部屋¥", you may also say ¥"four-and-a-half-jo room¥", if you want to preserve the original Japanese pronunciation. However, this is still a minority; there are only two examples of this in Google.
