## According to Ashkenazim, for [[Motzei Matzah]], some say that one should eat 4/5 of a machine [[matzah]], some say 2/3 of a [[matzah]], and others say 1 [[matzah]]. For [[Korech]], some say that one should eat 2/5 of a [[matzah]], some say less than 1/2 of a [[matzah]], and others say 2/3 of a [[matzah]]. For [[Afikomen]], some say that one should eat 4/5, some say more than 1/2, and others 1 [[matzah]].<ref>

* Mishna Brurah 486:1 writes that Tosfot holds a [[Kezayit]] is half of a KeBeitzah with the shell and the Rambam holds it is a third of a KeBeitzah (see Tosfot (Yoma 80b D”H Agav), Rambam (Eiruvin 1:9)). Rav Avraham Chaim Noeh (Shiurei Torah 3:12) argues that Tosfot holds half a KeBeitzah without the shell. Mishna Brurah 486:1 rules that for Deoritta Mitzvot and [[Bracha Achrona]], one should eat the size of half a KeBeitzah, but for Derabbanan Mitzvot, one third suffices. He adds that since one has to make a Bracha on [[maror]], one should eat half a KeBeitzah.

* The Tzlach (Pesachim 116) holds that the modern day eggs are half the size of those in the days of Chazal. However, Rav Noeh (Shiurei Torah Shaar 3) argues that the modern day eggs have not changed from the days of Chazal. Mishna Brurah 486:1 writes that for the mitzvah deoraitta of [[matza]], one should follow the stringent view of the Tzlach. Even though Vezot HaBracha (pg 6, Birur 1, pg 221) quotes Rav Elyashiv and Rav Shlomo Zalman saying that for [[Bracha Achrona]] the widely accepted measurement of the [[Kezayit]] is according to Rav Chaim Noeh, in regards to the mitzvah of eating [[matza]], Rav Shlomo Zalman writes in Halichot Shlomo 9:13 that one should be strict for the size of the [[Kezayit]] of the Chazon Ish which are based on the opinion of the Tzalach.

* Practically, how much [[matza]] is that? The following [[measurements]] are in regards to a piece of the average machine [[matza]]. Rabbi Dovid Feinstein (Haggadah Kol Dodi, 5745 p. 1) notes that [[matzah]] which fills the volume of 1.5 fluid ounces (44cc) weighs 31 grams (coming out to 705kg/m^3 which is about 70% the density of fresh water).
