How Many Walls Make a Kosher Sukkah?

Ah, the Sukkah. That charming little temporary hut we call home for seven days – except it’s not really a home. It’s a home that’s not a home, and therein lies the paradox. Let’s dive into the wonderful (and occasionally puzzling) world of Sukkah design , where function meets form for the perfect temporary Sukkot dwelling. 


The Why Behind the Walls

Let’s rewind to that opening verse from Leviticus 23:42, “You shall dwell in huts (Sukkot) for seven days.” Pause and ponder for a moment. “Dwell,” it says. Not just “hang out,” not “pop by for a nosh.” Dwell, as in live there. Make it your place, your space, your humble abode.


But remember: It’s a hut, not a house. A glorified shade structure, if you will. Yet, the mitzvah– the commandment – is to live in it as if it were a home, all while remembering it’s, well, not. Confused? Welcome to the world of  Sukkah  design! 


Function Meets Form

Since the mitzvah is to dwell, your Sukkah needs to be functional. You’ve got to be able to eat, sleep, and, let’s be honest, maybe even take that mid-afternoon nap in there. If you can’t, well, it’s not a kosher Sukkah. But it also has to scream, “I’m just a hut!”– a reminder that this hut is to provide shade, not shelter, echoing back to the divine protection our ancestors had when they left Egypt. So yes, you need to be very aware of that leafy, branchy Schach above your head. More on Schach in our handy Guide to Buying Kosher Schach.


Dimensions of Dwelling (Or, How Not to Get Cramped)

How much space do you need? Well, enough to avoid becoming a human pretzel while eating. The Talmud tells us the bare minimum measurements: a Sukkah needs to be at least seven by seven  tefachim  (think handbreadths) and ten  tefachim  high. That’s enough space to fit your head , most of your body , and your meal.


But remember, you’re supposed to be living in this thing. So unless you’re auditioning for Cirque du Soleil, you’ll want something a bit more spacious. Make your Sukkahcozy! Bring in some furniture, a nice table, proper lighting – maybe even a La-Z-Boy. For handy tips, check out our how-to guides on furnishing and lighting your Sukkah.


How High is Too High?

Now, about height – there’s a maximum limit too. Twenty  amot  , which is roughly 31 feet or so. Why? Because if your Schach (that’s the leafy roof) is up that high, you might forget it’s even there. And that would be missing the point entirely. Plus, at that height, the shade would come more from the walls than the roof, and we’re aiming for “hut,” not “penthouse.”


What about width? The sky’s the limit! In fact, the ideal Sukkah could fit every Jew on earth. Just imagine the world’s biggest family reunion under one massive Schach.

Walls, Shapes, and Sukkah Geometry

Walls are crucial – after all, this is supposed to be a dwelling. The minimum setup is two walls and a third little extension. They can’t just be parallel; this isn’t a drive-through. You need two perpendicular walls with a third extension to keep things kosher.


But here’s a fun fact: In the Hebrew word for Sukkah, סכה, each letter represents a different possible configuration of your Sukkah’swalls, ranging from the most ideal to the most minimalist. Let’s break it down.


Samech (ס): The Perfect Circle — Four Walls

First up, the letter  samech  (ס) . This is the gold standard, the Sukkahat its most robust and secure, four walls, perfectly enclosing you on all sides.


Kaf (כ): The Cozy Corner — Three Walls

Next, we have  kaf  (כ). Unlike the all-encompassing samech, the kaf opens up on one side, giving us a  Sukkah  with three walls. This is your classic “cozy corner” setup. It’s still solid, still feels like a real dwelling, but there’s a bit more openness – a nod to the temporary nature of this hut. Three walls make for a Sukkah that’s both stable and inviting, with just a hint of the outdoors peeking in.


Hey (ה): The Minimalist’s Dream — Two and a Half Walls

Finally, we come to hey (ה). This one represents a Sukkah with just two and a half walls. Imagine it: two solid walls forming a corner, and then a little extension – just enough to give you that third dimension. It’s minimalist, functional, and still totally  kosher  . It’s the Sukkah that keeps things simple, reminding us that sometimes less is more (this also applies to Sukkah decorating , by the way. Find out more about that in our article on Chabad’s ‘less is more’ approach to Sukkah decorations).
