5 Common Questions Asked About Mezuzahs

You've got the mezuzah case. Maybe it was a gift. Maybe you just moved into your first home and someone told you it goes on the door. But which door? And what happens if you move next year do you take it with you or leave it?

These are the questions people actually ask. And mezuzah rules, while rooted in ancient Jewish law, are more specific than most guides admit. This post answers the five most common ones directly.

Quick Answer:

A mezuzah goes on the right doorpost as you enter, in the upper third of the doorpost, on every qualifying room except the bathroom. Ashkenazi Jews hang it at a diagonal; Sephardi Jews hang it vertically. You generally cannot take it with you when you move if the next occupant is Jewish.

What Does a Mezuzah Contain?

Inside every mezuzah case is a small parchment scroll called a klaf, handwritten by a trained scribe (a sofer). On it are two passages from Deuteronomy: 6:4-9 and 11:13-21. The first is the Shema, the central declaration of Jewish faith. "Hear O Israel, the Lord our God, the Lord is one" (Deuteronomy 6:4). On the back of the scroll, the word Shin-Dalet-Yod is inscribed, one of God's names.

The case itself can be made from any material. Olive wood, brass, ceramic, silver. You can see the range in any handmade mezuzah collection sourced from the Holy Land. But the scroll inside is what makes it kosher. A beautiful case with a printed or missing scroll isn't a mezuzah. It's decoration.

Which Doors Actually Need a Mezuzah?

This is where most people get it wrong. The common assumption is that only the front door needs one. It doesn't work that way.

The rule, sourced from Shulchan Aruch Yoreh Deah 286, is that a mezuzah belongs on every doorway that leads into a qualifying room. A qualifying room has two doorposts, a lintel connecting them at the top, and a minimum floor area of roughly 6.5 feet by 6.5 feet (about 36-42 square feet depending on the authority you follow).

Rooms that need a mezuzah:

• Front door (always first)

• All bedrooms

• Kitchen

• Dining room

• Living room

• Home office or study

• Hallways and vestibules

• Walk-in closets (if they meet the size requirement)

• Garage (including the door from garage to house)

• Attic and basement (if used as living or storage space)

• Balconies and patios with proper doorposts

• Doorways with no actual door, if they have two posts and a lintel

Rooms that do not need one:

• Bathrooms and shower rooms (more on this below)

• Rooms smaller than the minimum size

• Storage rooms used for nothing else

• Rooms without a proper lintel or two doorposts

One detail surprises people: if a room has three doorways leading into it, each doorway needs its own mezuzah. Not one shared between them. Each entrance is its own obligation. That's worth keeping in mind before you order a modest three-bedroom home often needs seven or eight, which you'll find across the Judaica mezuzah collection.

Why Is the Mezuzah Slanted? Ashkenazi vs Sephardi

You've probably noticed that some mezuzahs hang at an angle and others sit perfectly upright. Both are correct. They come from a real disagreement in medieval Jewish law that was never fully resolved.

The debate started between two 11th-12th century scholars. Rashi said the mezuzah must be vertical, like a Torah scroll standing in the ark. His grandson Rabbeinu Tam disagreed and said it should be horizontal, like a Torah scroll lying open on the reading table. Neither position won.

So Ashkenazi authorities, led by Rabbi Moshe Isserles (the Rema), codified a compromise: tilt it. The slant satisfies both opinions simultaneously because Rashi only prohibited horizontal and Rabbeinu Tam only prohibited fully vertical. A diagonal fulfills both. This ruling is recorded in Shulchan Aruch Yoreh Deah 289:6.

Sephardi and Mizrahi Jews never adopted the compromise. They follow Rashi and hang theirs vertically. Both are valid within their own tradition.

If you live in a building with both Ashkenazi and Sephardi residents, the ruling from Dinonline (based on the Minchas Eliezer) is to hang it on a slant. The slant is acceptable for everyone. A diagonal doesn't offend either tradition.

How to Hang a Mezuzah: Placement, Side, and Height

Right side, upper third or tilted inward (if Ashkenazi). Here's what they mean in practice.

Which side: Always the right doorpost as you enter the room. Stand outside the doorway facing in. Your right side is where it goes. For interior doorways between rooms, the working principle is direction of primary use. Which direction do most people walk through it most of the time? That determines which side is "entering."

How high: The mezuzah belongs in the upper third of the doorpost. Measure the full height of your doorpost and divide by three. The bottom of the mezuzah should sit at or just above the two-thirds mark. On a standard 78-inch doorway, that puts the bottom of the mezuzah at roughly 52 inches from the floor. For very tall doorways of 90 inches or more, Chabad advises shoulder height instead, so it stays reachable.

The blessing: Before you hang the first mezuzah, recite this blessing once:

Baruch Atah Adonai Eloheinu Melech HaOlam, asher kidishanu b'mitzvotav v'tzivanu likboa mezuzah.

Blessed are You, Lord our God, King of the universe, who has sanctified us with His commandments and commanded us to affix a mezuzah.

Say it once. Then hang all the mezuzahs without interruption. The word "likboa" in that blessing means to fix firmly. That's why the method of attachment matters. Nails or screws are preferred. Strong double-sided tape is acceptable. Scotch tape is not. If it wobbles or peels, it hasn't met the standard the blessing itself describes.

Why Is There No Mezuzah on the Bathroom Door?

Because it's prohibited. Not just discouraged. The Talmud (Yoma 11a) rules that a mezuzah must not be placed on the doorway of a room used for bathing or undressing. The reason given by the Rishonim is respect: a sacred object containing God's name should not be present near people in a state of undress.

This applies to:

• Bathrooms

• Shower rooms

• Mikveh rooms

• Dedicated changing rooms

What about an en suite bedroom, where the toilet and shower are part of the bedroom itself? That's a bedroom. A multi-purpose room doesn't lose its status because it contains bathroom fixtures. It still needs a mezuzah on the door (Ohr Somayach, Mezuzah Maven).

One more nuance: a corridor that leads only to a bathroom doesn't need a mezuzah either. But if that same corridor also leads into another qualifying room, it does. The corridor takes its status from where it goes.

Can You Take a Mezuzah When You Move?

This is where people are surprised. Jewish law takes this seriously.

The ruling from the Talmud (Bava Metzia 101b-102a) is that you generally cannot remove your mezuzahs when moving out if a Jewish person is moving in after you. The reasoning has two parts. First, a mezuzah placed on a Jewish doorpost has sanctity. Removing it unnecessarily is inappropriate. Second, a home without a mezuzah loses a layer of protection before the next family can put theirs up.

Here's how the rules break down:

One exception worth knowing: if there's genuine concern that the mezuzahs will be damaged or disrespected by the new occupants, you may remove them even if they are Jewish. A rabbi should be consulted if there's any doubt about how to proceed. And if you do take yours, the full Judaica collection is a good place to find kosher replacements for the new home.

FAQ

Do I need a mezuzah on every door in my house?

Almost every door, but not every single one. Bathrooms are exempt. Rooms smaller than roughly 36-42 square feet don't qualify. Rooms used purely for storage that have no other purpose also don't require one. Every other qualifying doorway does. A typical three-bedroom home routinely needs seven or eight mezuzahs, sometimes more.

What side of the door does the mezuzah go on?

The right side as you enter. Stand outside the doorway facing inward. The right doorpost is where it belongs. This applies to every qualifying doorway in the home, including interior doors. For doors you walk through in both directions regularly, the direction of primary use determines which way is "entering."

Can a non-Jewish person hang a mezuzah?

The commandment in Deuteronomy 6:9 ("write them on the doorposts of your house and your gates") is given to the Jewish people as a mitzvah. That said, Messianic believers often hang mezuzahs as an expression of connection to the Hebrew roots of their faith, and many Christian families hang them as a reminder of scripture. The Messianic mezuzahs at Holy Land Market are crafted specifically with that audience in mind.

How often do you check a mezuzah?

Twice every seven years is the minimum required by Jewish law. Many observant families have theirs checked annually. The scroll inside can crack or fade, and a single unreadable letter makes the entire scroll non-kosher. Don't check it yourself. Take it to a qualified sofer (scribe) who can read and certify it.

What do you do with a damaged mezuzah scroll?

Don't throw it away. A damaged mezuzah scroll is a sacred object and must be treated accordingly. Take it to a local synagogue, where it can be placed in the Genizah, a storage place for worn or damaged sacred texts. From there, it's eventually buried in a Jewish cemetery. You can then hang a new kosher scroll in its place.

Why do people kiss the mezuzah?

The practice goes back to the Middle Ages. When leaving or entering the home, many people touch the mezuzah with their fingertips and then kiss their fingers. Rabbinical tradition holds that it's a moment to say a brief prayer, ask for protection, and acknowledge God's presence at the threshold. It instills what the tradition calls mindfulness at the doorpost. Not a requirement. But a meaningful habit.

Conclusion

Mezuzah rules aren't complicated once you understand the reasoning behind them. Right doorpost. Upper third. Every qualifying room except the bathroom. The slant is a compromise between two great medieval scholars, and it's a rather elegant one. And when you move, you don't just pack up your mezuzahs without asking who's moving in next.
