Notes:
- 1 Although the Torah level obligation is to eat only a single kezayis, it is a rabbinic requirement to eat a total of five kezaysim throughout the seder.
- 2 0.63 fl. oz. per kezayis is according to Rabbi Dovid Feinstein. 0.97 fl. oz. per kezayis is according to the stringent opinion of Rabbi Avraham Chaim Naeh.
- 3 Assuming 8 hand matzos per pound and 15 machine matzos per pound. Pictures show minimum percentage based on the most stringent opinion.
- 4 One should fill up the cup to the top even if it is larger than a revi'is. Since some hold that one should drink the entire cup, if one plans to drink only a revi'is, one should use a cup that only holds a revi'is.
- 5 2.9 fl. oz. per revi'is is according to Rabbi Avraham Blumenkrantz. 5.1 fl. oz. per revi'is is according to Chazon Ish. Especially on Erev Shabbos, it is preferable to use the more stringent opinion.
