Tractate Middot (Hebrew: מִדּוֹת, lit. "Measurements") is the tenth tractate of Seder Kodashim ("Order of Holies") of the Mishnah and of the Talmud. This tractate describes the dimensions and the arrangement of the Temple Mount in Jerusalem, and the Second Temple buildings and courtyards, various gates, the altar of sacrifice and its surroundings, and the places where the Priests and Levites kept watch in the Temple.
The tractate is divided into five chapters and has no Gemara either in the Jerusalem Talmud or the Babylonian Talmud, nor a Tosefta.
