Gi or No-Gi for Beginners: Which Should You Start With?

You found a gym, you watched a class, maybe you already booked a trial. Then you hit a fork in the road nobody warned you about: gi or no-gi. One involves a heavy cotton uniform and a belt. The other looks like someone went training in swim trunks. Both are jiu jitsu, both will humble you in week one, and the internet will happily argue about them for the rest of your life.

Here is the plain version, with the actual rules behind it.

The short answer, if you only read one paragraph

Start with whichever one your gym runs most often at the times you can actually show up. That is it. Some gyms only teach no-gi, in which case the choice is already made for you. Mat time beats theory, and the fastest way to quit before you start is to build your whole plan around a Wednesday no-gi class you are never going to make. If your gym runs both at times that work, start in the gi. The grips slow everything down, which gives a brand-new person a few extra seconds to think, and the belt system you will spend the next few years in is built around it.

Now the detail, because "just pick one" is not very satisfying when you are the one about to walk in.

What "gi" actually means

The gi is the uniform: a jacket, pants and a belt. Gyms are usually relaxed about it. The competition rules are not, and they are a useful picture of what the thing is supposed to be. Under the International Brazilian Jiu-Jitsu Federation rulebook, as it read on October 5, 2026, a competition gi has to be cotton or cotton-like, woven, and for juvenile, adult and master divisions a pearl weave is mandatory. It has to be a single color, and only three are allowed: white, royal blue or black. The jacket has to reach your thigh, the sleeves have to come no more than 2 cm from your wrist with your arm held straight out, and the pants have to stop no more than 2 cm above your ankle bone. The belt is 4 to 5 cm wide, in your rank color, with a black tip.

Your first class will not involve a tape measure. But those numbers are why a gi that fits fine in the store can still look too short to a referee, which is worth knowing before you spend money. We wrote a whole sizing, weave and fit guide on exactly that.

What "no-gi" actually means

No-gi is a rash guard and shorts. Again, the federation rules spell it out more precisely than your gym will. As the same rulebook read on October 5, 2026, the shirt has to be skin tight elastic material, long enough to cover your torso all the way to the waistband of your shorts, colored black, white, or black and white, with at least 10 percent of your rank color on it. A shirt that is 100 percent your rank color is fine too. Board shorts have to be black, white, or your rank color, with no pockets or with the pockets sewn completely shut, and with no buttons, exposed drawstrings or zippers, because all of those can catch a finger or a toe. They have to cover at least halfway down your thigh and stop at the knee. Undergarments are mandatory in both.

Notice the thing hiding in that list. Even with no belt tied around you, your rank still has to be visible. That 10 percent rule is how a no-gi room knows who is who. If you are still working out what those colors mean in the first place, here is the full belt order.

The one rule that changes how it feels

If you want to understand the difference in a single line, it is this one, straight out of the fouls list: in no-gi, grabbing hold of your own uniform or your opponent's "in any way" is a foul.

That is the whole thing. In the gi you can hold a collar, a sleeve, a lapel, a pant leg. Cloth does not slip, so you can take a grip, hold it, and build something slowly from there. In no-gi there is nothing to hold except the person. You end up on underhooks, wrists, head position and whatever you can lock with your own arms, and because there is less to hang on to, the pace goes up and people slide out of positions you thought you had. Same art, different friction.

That is also why people who only train one and then try the other feel like a beginner again for a few weeks. It is not a different sport. It is the same sport with the handles taken off.

The rules are not identical either

This matters less than beginners think, but it is good to know it exists. The rulebook's table of illegal moves has a column of its own for adult brown and black belts in no-gi, because that group is allowed things nobody else is. Since a rule change announced in January 2021, they can use heel hooks and knee reaping in no-gi divisions. Those stay illegal for white, blue and purple belts, and for masters competitors.

Read that as good news. At white belt the list of things you are allowed to do is close to identical whichever one you wear, and the leg lock argument you see online is happening several years up the road from you.

What each one teaches you first

This part is our read, not a rule. Take it as a point of view.

The gi rewards patience and precision. Friction buys you time, so you have room to notice what your hands are doing and why a grip works. That is genuinely useful early, when the problem is usually that you are moving fast and accomplishing nothing.

No-gi rewards position and pressure. With nothing to grab, you learn fast that connection comes from where your hips and head are, not from your fingers. It also feels more athletic right away, which a lot of people love from the first round.

I will admit my own bias here: I love the gi, and the reason is the handles. Every collar, sleeve and lapel is something to hold, so the game gets deeper and wider, with more ways to control someone, more sweeps and more submissions. That same depth can also be overwhelming, and it is a perfectly good reason someone might enjoy no-gi more.

No-gi also has the wind at its back. As I see it in 2026, no-gi competition gets a lot more of the media coverage and a lot more interest from people outside the sport.

Most people who stick around end up doing both, and the mix tends to come in seasons. At purple belt I played a lot of lapel guard in the gi, which is a style of guard built on gripping and wrapping your partner's lapel, and I started to wear my fingers out. By brown belt I was giving my fingers a rest in no-gi and working on leg locks. That stretch is also when I learned to tape my fingers.

The two make each other better. You do not have to decide forever. You are deciding what to do on Tuesday.

What it costs to walk in the door

Gi: one purchase, and the belt usually comes with it, which means your first homework is learning to tie the thing. Plenty of gyms keep loaners for trial classes, so ask before you buy anything.

No-gi: a rash guard and shorts, usually a cheaper start. The catch is quantity. That gear is thin, it soaks through fast, and it needs washing after every session, so one of each gets old quickly. The same is true of a gi, which is why we also wrote about washing the thing properly.

On brand: buy whatever your academy sells, or whatever fits you, from anyone. We make gis and no-gi gear both, so we genuinely do not have a side in this argument, and a beginner is better served by gear that fits than by a logo. Good brands are good for all of us.

Honestly, just ask the gym

Most places are far more relaxed about this than the rulebook suggests. In the Gold BJJ "State of Jiu Jitsu" survey run in late 2024 and early 2025, only 502 of 1,920 US respondents, about 26 percent, said their gym had a uniform policy at all. Which means roughly three out of four people are training somewhere that is not going to inspect your shorts.

So before your first session, send one message and ask five things: which nights are gi and which are no-gi, what beginners are expected to wear, whether the gym requires its own patch or branded gear, whether there is a loaner gi for a trial, and whether the beginner class is separate. That one message answers this entire post for your gym, which is the only answer that matters.

The patch question is worth asking before you spend anything. Some gyms require their patch, or gear with their name on it, on your gi or your no-gi kit, and it is a lot nicer to know that before you buy something you are not allowed to wear.

And if you are still working out what the hour itself looks like, we walked through that too, in what to expect in your first class.

Pick one and go

Show up to the class that fits your schedule, wear what the gym tells you, and get your reps. You can have the gi versus no-gi opinion later, once you have earned one. We will be glad you started either way.
