A kosher mezuzah on every doorway is
the foundation of a Jewish home
If you need both a mezuzah klaf,
mezuzah scroll, and a mezuzah case,
start by first choosing from HaSOFER's wide selection of mezuzah cases. This is because the size of the mezuzah
case determines the size of the mezuzah scroll you need. Note that the size listed for all HaSOFER mezuzah cases is
the size of the mezuzah scroll appropriate for that mezuzah case and not the overall height of the mezuzah case.
Mezuzah parchments come in standard heights of 6, 10, 12, and 15 centimeters. Until recently,
mezuzah parchments taller than 6 centimeters were not commonly found, but this has changed as
high quality parchment has become more accessible and more reasonably priced. The most commonly
used sizes today, and also the most economical, are 10 and 12 centimeter. For a higher quality
mezuzah, however, choose the larger, 15 centimeter size. If a small mezuzah scroll is absolutely
essential, be prepared to pay more for this, as it is more difficult to write. A 6 centimeter mezuzah
parchment is more expensive than a 10 or 12 centimeter parchment of equal quality.
Life expectancy of all of HaSOFER's 10 and 12 centimeter mezuzah parchments is approximately 20
years and not a factor of the price you pay for the klaf. A 6 centimeter mezuzah parchment has a shorter life expectancy
as its smaller letters have a smaller surface area for bonding to the parchment. The actual
lifespan of a mezuzah klaf varies greatly, depending upon how much it is exposed to heat,
cold, dampness, dust, direct sunlight, and other factors.
Except for special circumstances, it is strongly advised by all poskim, rabbinical authorities,
to replace existing small mezuzah cases, those less than 6 cm or 2.5 inches tall, with a larger
mezuzah case and a mezuzah klaf sized to match. However if you have an heirloom
mezuzah case or one with great sentimental or monetary value, we can provide you with a
mezuzah klaf to fit it. To determine the size mezuzah parchment you need, measure the
internal length and depth of your mezuzah cover carefully, leaving sufficient room for closing the mezuzah
without crushing, creasing or rolling the parchment too tightly.
If your mezuzah will be exposed to direct sunlight, dampness or extremes in temperature,
choose one of HaSOFER's simple yet elegant
LeDOROT mezuzah cases or one of our other
weather resistant mezuzah cases.
If you are putting up the mezuzah on a steel or other doorframe on which you cannot use screws,
choose one of our many styles of
self-adhesive mezuzah cases designed for mounting without using either nails or screws.
To learn about the factors you should keep in mind as you choose your mezuzah case read our article
The Three Purposes of Your Mezuzah Case.
To be sure you're putting your mezuzah up correctly read Where and How to Put Up a Mezuzah. On this page you'll find printable summaries in English, Hebrew and Russian
of the laws of how to put up a mezuzah.
All of HaSOFER's mezuzah klafim are written by our own certified sofrim, scribes,
using only the highest quality natural parchment and ink. Each klaf is examined twice
manually by certified megihim, examiners, and then also checked by computer.
The kashrut level and price of every mezuzah klaf is set by HaSOFER's poskim
according to the scroll's adherence to Halacha, Jewish Law, and its
level
of hiddur, beauty and enhanced level of kashrut. HaSOFER's poskim include:
HaRav HaGaon Shamai Gross, shlit"a, Rabbinical Authority for K'hal Machzikei HaDas
in Israel and Mishmeres HaKodesh for STa"M, and author of Shevet HaKehati.
HaRav HaGaon Mordechai Friedlander, shlit"a, Rabbinical Authority for Machon Mishmeres STa"M in Jerusalem.
