How do I put up a mezuzah?

Mezuzahs need to be affixed on every doorway of your home or apartment with the exception of the bathrooms.1

The Mezuzah should be affixed on the right side of the doorway entering a room on the bottom of the upper third and should be at an angle so that the top of the mezuzah is pointing to the inside of the house or room. If the mezuzah is lower than the top third of the doorway it must be removed and properly repositioned. However, if it is higher than the bottom of the top third, as long as it is more than 3.3 inches from the top of the doorway, it needn’t be removed.2

Often times it is difficult to determine which doorpost is the right one and which one is to the left – which side of the door is considered the “inside” and which side is the “outside”; it depends on the position of the door, the hinges, and the rooms it opens into. Therefore, upon moving into a new residence it is recommendable to contact a rabbi who can come and show you exactly where to affix the mezuzahs on every doorway. [Additionally, not every doorway requires a mezuzah. For example, some doorways do not have two doorposts, are domed at their tops, etc.3 Bringing a rabbi to see your home might spare you the possibility of affixing unnecessary mezuzahs.] Click here to find a rabbi in your area who will be happy to assist you.

The mezuzah should be affixed within 3.3. inches from the outside of the door (i.e. the side which the rabbi determines to be the “outside”).4

Before affixing a mezuzah, the following blessing is said: [If affixing more than one mezuzah, this blessing is recited before attaching the first one only.]

"Baruch atta Ado-noy Elo-hai-nu Melech ha'olam asher kid-e-sha-nu b'mitz-vo-tav v'tzi-vanu lik-bo-a mezuzah."

[Blessed are you, Lord our G-d, King of the universe, who has sanctified us with His commandments, and commanded us to affix a mezuzah.]

Note: A Mezuzah cannot be affixed on the Sabbath or any of the Biblical holidays or festivals when "work" is forbidden.

[Ed. note: Also read "Why is the mezuzah affixed at an angle?"]

It is forbidden to erase or deface the name of G-d. It is therefore customary to insert a dash in middle of G-d's name, allowing us to erase or discard the paper it is written on if necessary.
