There is a massive trend in the martial arts community right now: the home dojo. Whether you are trying to log extra drilling hours outside of class, stay sharp when life gets busy, or build a dedicated space to train with trusted partners, a home Brazilian Jiu-Jitsu setup is a game-changer.
But before you start clearing out the garage or rearranging the spare bedroom, the number one question you need to answer is: How much space do I actually need?
Too little space means stubbing your toes on the skirting boards during an armbar transition. Too much space might mean wasting money on mats you don’t use.
Let’s break down the exact dimensions required based on your training goals, and how you can maximize your layout.
If you are training solo—focusing on shrimping, reverse de la riva entries, inversion drills, yoga, or stretching—you don’t need a massive room.
The Reality: A single Hikari Core Series® Roll-Out Mat gives you a 1.5m x 3m ($4.5m^2$) training zone.
Who it’s for: Practitioners using instructionals, drilling on a grappling dummy, or combining BJJ conditioning with mobility and fitness work. It fits perfectly into a standard bedroom or living room space and can be rolled up in under 60 seconds.
If you intend to invite a drilling partner over to work through techniques, guard passes, and light “flow rolling” (where you move smoothly without explosive intensity), you need to expand your perimeter.
The Reality: You need at least a 3m x 3m area.
The Setup: This is easily achieved by pairing two Hikari Core Series® Mats side-by-side.
Who it’s for: Friends looking to break down seminar footage or drill specific guard transitions without constantly resetting because they hit a wall.
If you want to slap, bump, and roll at 100% intensity, space becomes a safety requirement. When bodies start scrambling and sweeps get explosive, you travel surprisingly far.
The Reality: A minimum of 3m x 6m is ideal for safe, live sparring, though it might not be possible in all households.
The Setup: 3-4 roll-out mats linked together provide the ultimate garage or spare room dojo experience. Our Core PLUS range can do this with ease – See Core PLUS Mats
When measuring your room, do not just measure the mats—measure the walls.
The Golden Rule of Home Dojos: Always aim for at least 0.5 meters of clear buffer space between the edge of your mats and any hard surfaces, furniture, or walls. If you have to place mats flush against a wall, consider investing in wall padding for high-impact zones.
If your room is exactly 3m x 3m and you buy 3m x 3m worth of mats, you have zero margin for error. Crashing your head into a plasterboard wall or an exposed radiator during a hip bump sweep is an easy way to ruin your training week.
If you are setting up a home gym on top of concrete garage floors or hardwood laminate, standard 10mm yoga mats or cheap puzzle mats aren’t going to cut it. You will feel the floor through every single transition.
For BJJ and MMA, look for:
High-Impact XPE Foam: Cross-linked polyethylene (XPE) foam provides exceptional shock absorption without being too soft. If a mat is too squishy, your feet sink, which slows down your movement and risks twisted ankles.
40mm Depth: Our Core Series mats utilize a firm 40mm thickness specifically engineered to protect your joints during heavy drops and ground work, keeping you safe even on concrete subfloors.

Here’s how to clean roll out mats. Whether you are drilling double-legs to downward dog, practicing your BJJ flow, flowing through a yoga sequence, or getting some extra home reps in on your roll-out mats, there is one opponent you cannot afford to ignore: bacteria.
