How to Choose a Mezuzah
15 June 20266 min read

Quick answer
A mezuzah is two things: the decorative case and the kosher scroll (klaf) inside it. The scroll is what matters religiously and must be hand-written and certified—many cases ship empty, so check the listing. Size the case to your doorpost, pick a weatherproof material for outside doors, and buy the scroll from a store that states its certification.

Case vs. scroll: what you're actually buying
The mezuzah case is the visible holder; the klaf is the hand-written parchment scroll inside. Religiously, the scroll is the mezuzah—the case is decoration and protection. The most common mistake shoppers make is buying a beautiful case that arrives empty.
Always confirm whether a listing includes a kosher, certified scroll. If it doesn't, buy the scroll separately so the mezuzah is complete and ready to hang.
- Case = decorative holder
- Klaf = the hand-written certified scroll (the actual mitzvah)
- Check every listing: 'includes kosher scroll' or not
Scroll certification and quality
A kosher klaf is written by a trained scribe (sofer) and should come with certification. Quality and price vary with the script and the scribe. For a gift or a primary doorway, buy a certified scroll from a store that states its supervision rather than an uncertified novelty scroll.
We don't validate individual scrolls—rely on the store's certification and, for anything you're unsure about, a qualified sofer's check.
Sizing the case to your scroll and door
Cases and scrolls are sold by size, and they need to match—a 12cm case takes a 12cm scroll. Measure your doorpost too: a slim case suits apartment door frames, while larger statement cases want a wider post. When in doubt, mid-size (around 12cm) is the most versatile.
- Match case size to scroll size (e.g. 12cm to 12cm)
- Slim cases for narrow apartment frames
- ~12cm is the most versatile default
Indoor vs. outdoor and material
Your front-door mezuzah faces weather, so choose a sealed metal, stone, or quality acrylic case rather than untreated wood or delicate ceramic. Interior doors can use any style. If you're outfitting a whole home, many shoppers buy one statement case for the front door and simpler cases for interior rooms.
Buying and shipping
Because a complete mezuzah pairs a case with a certified scroll, order from a store that makes the certification clear and can ship both together. For a new home or a wedding gift, allow lead time for engraving or out-of-stock sizes. The comparison guides below rank stores by overall fit and shipping speed.

FAQ
Frequently asked questions
Does a mezuzah case come with a scroll?
Not always. Many cases are sold empty, and the kosher scroll (klaf) is what fulfills the mitzvah. Check the listing for 'includes kosher scroll'; if it doesn't, buy a certified scroll separately so the mezuzah is complete.
What size mezuzah should I buy?
Match the case and scroll sizes (a 12cm case needs a 12cm scroll) and consider your doorpost width. Around 12cm is the most versatile size for most doors; slim cases suit narrow apartment frames.
What makes a mezuzah scroll kosher?
It must be hand-written by a trained scribe (sofer) on parchment and come certified. Buy from a store that states its certification, and have a qualified sofer check anything you're unsure about—novelty or printed scrolls are not kosher.
Can I use any mezuzah outside?
Use a weatherproof case outdoors—sealed metal, stone, or quality acrylic—rather than untreated wood or delicate ceramic, which degrade in the elements. Interior doors can take any style.
