Martial Arts for Kids: 10 Styles Compared
Karate, taekwondo, Brazilian jiu-jitsu, judo and six more styles side by side: what each teaches, when kids can start, how belts work, what classes cost and how to spot a good school.
Martial arts for kids come in two main kinds: striking arts like karate and taekwondo, which teach punches, kicks and forms, and grappling arts like Brazilian jiu-jitsu and judo, which teach throws, pins and holds without strikes. Most kids’ classes start around age 4 to 6. Schools we checked charge about $65 to $230 a month in 2026, plus registration and belt-testing fees. Pediatricians advise learning skills before sparring, and the best style for your child is the one taught well near you.

10 martial arts styles for kids
Grouped into striking arts, grappling arts and the rest. Ages and prices are examples from schools’ own pages and the sports’ governing bodies, checked in October 2026. What matters most is the school near you, so use these to know what to look for and what to ask.
Striking arts: karate, taekwondo, kung fu and Muay Thai
Punches, kicks, blocks and forms, learned in lines and with pads before any sparring. These are the most common kids’ classes in the U.S.
Karate
- Cost
- Examples: $64–$85 a month (2026)
- Ages
- Often from 4 or 5; some schools at 3
Good for Kids who like clear steps and solo practice
Karate, from Okinawa and Japan, focuses mostly on strikes with the hands, along with kicks, blocks and strong stances. Kids drill the basics, learn kata (set sequences of moves) and, as they progress, kumite, or sparring. Belt colors and tests vary by style and school: Kanzen Karate Do in Alabama, for one, goes white, yellow, purple, orange, red, green, blue, brown and black, at $45 a test. Karate has been an Olympic sport only once, at Tokyo 2020.
- Striking: hands first, then kicks
- Forms are called kata
- Sparring is called kumite
- Olympic only at Tokyo 2020
Taekwondo
- Ages
- Often from 3 to 5
Good for Energetic, flexible kids who love to kick
Taekwondo, from Korea, leans more on the feet: high, fast, spinning and jumping kicks, plus forms called poomsae and padded sparring as kids advance. It has been a full Olympic sport since 2000. USA Taekwondo, the national governing body, requires background checks for its coach and instructor members. In the Kukkiwon system, a black belt earned before 15 is a junior poom rank, which can be converted to an adult dan rank at 15. Some schools start preschoolers at 3 in 30-minute classes.
- Mostly kicks
- Forms are called poomsae
- Olympic sport since 2000
- Junior black belt: poom rank
Kung fu
- Cost
- Example: $94–$137 a month (2026)
Good for Kids drawn to forms and tradition
Kung fu is the umbrella name for China’s many martial arts styles. Classes usually mix stances, strikes and kicks with long forms, and some schools add traditional weapons as students advance. Its competitive side, wushu, is overseen in the U.S. by the USA Wushu Kungfu Federation. Because styles differ so much, ask which one a school teaches. The Academy of Kung Fu in Ridgeland, Mississippi, charges $137 a month for two kids’ classes a week on a 12-month plan, testing included, or $94 for one class a week.
- Many styles under one name
- Forms, strikes and kicks
- Sport version: wushu
Muay Thai and kickboxing
- Cost
- Example: $125 a month plus a sign-up fee
- Ages
- Kids’ classes we found: 7–12
Good for Older kids who want a hard workout
Muay Thai, from Thailand, strikes with fists, feet, elbows and knees and adds clinching; kickboxing usually sticks to punches and kicks. Kids’ classes focus on technique and fitness, and the AAP’s advice is to learn skills without contact before any sparring, with contact to the head discouraged. Ask how the gym changes adult rules for children. Mitten Muay Thai in Rochester Hills, Michigan, teaches ages 7 to 12 on Tuesdays, Thursdays and Saturdays for $125 a month plus a sign-up fee.
- Punches, kicks, elbows, knees
- Kickboxing: punches and kicks
- Ask about head contact for kids
Grappling arts: Brazilian jiu-jitsu, judo and aikido
No punching or kicking: kids learn to fall safely, throw, pin and hold, nearly always with a partner.
Brazilian jiu-jitsu
- Ages
- From 4 (IBJJF kids’ belts cover 4–15)
Good for Kids who like wrestling and problem-solving
Brazilian jiu-jitsu is grappling with no punches or kicks: kids learn to control a position, escape a bad one and finish with a submission their age group may use, then test it in live practice called rolling. Under the IBJJF’s rules, kids 4 to 15 start at white and earn grey (from 4), yellow (from 7), orange (from 10) and green (from 13) belts, each with white- and black-striped steps; blue belt starts at 16 and black at 18. Most academies open kids’ programs between 4 and 6.
- Grappling, no strikes
- Kids’ belts: grey to green
- Blue belt from age 16
- Live sparring is called rolling
Judo
- Ages
- From about 5
Good for Kids who like rough-and-tumble partner play
Judo, founded in Japan by Jigoro Kano in 1882 and an Olympic sport since 1964, teaches throws, pins and groundwork, and first of all how to fall safely. There’s no striking, and nearly everything is done with a partner. USA Judo, the USJA and the USJF share a development model whose first stage, Discover the FUNdamentals, covers ages 5 to 8. USJF junior ranks, for 16 and under, run from white through yellow, orange, green and blue to purple, with half-steps; the first needs age 5 and 7 classes.
- Throws, pins and safe falls
- No striking
- Olympic sport since 1964
- Junior belts: white to purple
Aikido
- Cost
- Example: $160–$165 a month (2026)
- Ages
- Some dojos from 4
Good for Kids who prefer cooperation to competition
Aikido, from Japan, uses joint locks, throws and rolling falls, turning an attacker’s momentum aside rather than striking, and most aikido has no competition. A 2022 review of martial arts programs for children counted aikido among the styles that improved physical fitness. Tenzan Aikido in Seattle, for example, offers a free trial class for kids 4 and up and charges $160 to $165 a month for one child, plus a $69 registration fee per family.
- Joint locks, throws, rolling falls
- Usually no competition
- Partner practice, not sparring
MMA, Krav Maga and capoeira
A mix of striking and grappling, practical self-defense, and a Brazilian art played to music.
Mixed martial arts (MMA)
Good for Older kids, in a drills-only class
Mixed martial arts combines striking and grappling, and as a sport, fighters win on points or by making the opponent submit. The AAP’s parent guide says competitive MMA carries a relatively high risk of serious injury and should generally be discouraged for young athletes. Some gyms’ kids’ MMA classes are a structured mix of striking and grappling drills without fights; a small randomized study of a 26-class MMA-based program found better executive functioning in children with autism. Ask exactly what kids do in class.
- Striking plus grappling
- AAP: discourage for young kids
- Ask what kids’ classes involve
Krav Maga
Good for Kids who want practical self-defense
Krav Maga is a self-defense system developed in Israel. Instead of sport matches or set forms, classes drill practical defense, such as getting free of grabs, and many kids’ programs present it as anti-bullying training that starts with awareness and using your voice. Programs vary a lot from school to school, so ask about age groups, how much contact there is and how instructors teach kids to avoid a fight in the first place.
- Self-defense, not sport
- No sport competition
- Ask how much contact kids get
Capoeira
- Cost
- Example: $39 for a two-week intro
- Ages
- Pee-wee classes from 3
Good for Kids who love music, dance and tumbling
Capoeira, from Brazil, blends martial arts, dance, acrobatics and music. Players meet in a circle and play a game of kicks, dodges and cartwheels to instruments and songs in Portuguese, so kids pick up rhythm and some Portuguese along with the moves. AXÉ Capoeira Chicago, for one, runs Peewee classes for ages 3 to 5 built on games, music and movement, and family classes from age 6, with a $39 two-week intro.
- Martial art, dance and music
- Played as a game in a circle
- Builds rhythm and flexibility
Karate vs taekwondo vs jiu-jitsu (and judo) for kids
These four are the styles most parents choose between. Karate and taekwondo look alike from the doorway: lines of kids in white uniforms, belts, forms. Jiu-jitsu and judo look like wrestling. Here is how they compare:
| Karate | Taekwondo | Brazilian jiu-jitsu | Judo | |
|---|---|---|---|---|
| Main skills | Hand strikes, kicks, blocks, stances | Kicks, including high, spinning and jumping kicks | Ground control, escapes, submissions | Throws, pins and safe falling |
| Strikes? | Yes | Yes | No | No |
| A typical kids’ class | Basics, kata (forms), partner drills; sparring later | Basics, poomsae (forms), kicking drills; padded sparring later | Warm-up games, a technique, then live rolling | Breakfalls, throws with a partner, groundwork |
| Kids’ classes from | Often 4 or 5; some at 3 | Often 3 to 5 | 4 (IBJJF grey belts) | About 5 (USJF’s first junior rank) |
| Kids’ belts | Vary by style and school | Vary by school; under-15 black belts are poom ranks | White, then grey, yellow, orange, green; blue at 16 | USJF juniors: white to purple, with half-steps |
| Olympic sport | Tokyo 2020 only | Since 2000 | No | Since 1964 |
| Often suits | Kids who like clear steps and solo practice | Energetic kids who love to kick | Kids who like wrestling and puzzles | Kids who like rough-and-tumble play |
Instructors who teach both karate and taekwondo say the difference is small for a young child, and the gap between two schools of the same style is bigger. The real split is striking versus grappling. A grappling class gives kids live, resisted practice from early on, without blows to the head; a striking class gives them more solo practice and visible progress through forms and belts.
| Style | Mainly | Youngest kids’ classes we found | Competition |
|---|---|---|---|
| Kung fu | Strikes, kicks and long forms | Varies by school | Wushu tournaments |
| Muay Thai and kickboxing | Punches and kicks; Muay Thai adds elbows and knees | 7 (Mitten Muay Thai) | Bouts; ask about kids’ rules |
| MMA | Striking and grappling | Varies by gym | The AAP discourages it for young kids |
| Krav Maga | Self-defense | Varies by school | None |
| Aikido | Joint locks, throws, falls | 4 (Tenzan Aikido’s free trial) | Usually none |
| Capoeira | Kicks, acrobatics and music | 3 (AXÉ Capoeira Chicago) | Played as a game, not a match |
What martial arts classes cost
We didn’t find a reliable national average for kids’ martial arts tuition, so here is what a sample of schools post on their own sites. Most charge by the month; the extras are where costs differ.
| School | Style | Kids’ monthly price | Other fees |
|---|---|---|---|
| Kanzen Karate Do, Leeds, Ala. | Karate | $65 (ages 5–7, twice a week); $85 from 7 | $75 registration with uniform; $45 a belt test |
| Kensington Karate, San Diego | Karate | $64–$85 for one class a week (ages 6–12) | $99 registration; $45 a belt test, every 4–8 months |
| Academy of Kung Fu, Ridgeland, Miss. | Kung fu | $94 (one class a week) to $137 (two, 12-month plan) | $89 registration; $30 ceremony fee three times a year |
| Mitten Muay Thai, Rochester Hills, Mich. | Muay Thai | $125 (ages 7–12) | A sign-up fee; first month $49 |
| Sidekick Martial Arts, Hasbrouck Heights, N.J. | Kids’ martial arts | $160 (ages 6–14, new members from Oct 1, 2026) | $50 a belt test, every 3–4 months at most |
| Tenzan Aikido, Seattle | Aikido | $160–$165 for one child | $69 registration per family |
| Fonseca Martial Arts, Chicago area | Karate and jiu-jitsu | $199 (ages 4–6); $229 (7 and up) | No belt-test fees through provisional black belt |
Before you sign, ask for every required cost for the next 12 months in writing:
- Monthly tuition, how many classes it includes, and whether siblings get a discount
- Registration or enrollment fee, and whether it includes a uniform
- Belt-test fees, how often tests happen, and whether a child can be held back
- Required sparring gear, and whether you must buy it from the school
- Tournament, ceremony or black-belt program fees
- Contract length, cancellation terms and what happens if your child gets hurt or wants to pause
How to choose a martial arts school (and red flags)
There’s no license to run a martial arts school, so judge the school in front of you. The AAP’s advice for parents is to visit several instructors and ask about their experience with young children and how they teach. Then take a free trial and watch a regular class at the time your child would go:
- Who teaches the kids’ class every week, and how long have they taught children?
- Are classes split by age, with short drills for young kids?
- How do instructors handle a child who is struggling or distracted? Do they know names?
- Do older students show good technique? They show where the school takes kids.
- When does sparring start, with what gear, and is any contact to the head allowed for kids?
- What does a child have to show to earn the next belt?
- Is everyone who works with children background-checked?
Walk away if you see these:
- You can’t watch. A school that keeps parents out of sight of class is a no.
- A long contract on the first visit, especially with a today-only price.
- Guaranteed black belts or a fixed timeline to one, and promotions that line up with contract renewals.
- Surprise fees for tests or gear that only come up when your child is ready to move up.
- An instructor who won’t say who trained them or what organization, if any, their rank comes from.
- Hard contact for beginners, or young children sparring to the head.
If a coach belongs to an Olympic sport body such as USA Taekwondo or USA Judo, you can also search the U.S. Center for SafeSport’s disciplinary database for their name.
Martial arts for kids with autism or ADHD
Many families try martial arts for a child with autism or ADHD: the routine, the clear rules and the visible progress through belts can suit kids who struggle in team sports. The research is encouraging, but small:
- Autism. In a randomized study (Journal of Autism and Developmental Disorders, 2019), school-age children with autism who took a 26-class mixed martial arts program over 13 weeks showed better executive functioning than a waitlist group. A small 2016 study found 8 weeks of taekwondo improved balance. But a 2025 scoping review found only two studies that met its standards, both showing better coordination and balance, and called for better research.
- ADHD. In a 2022 randomized trial, 57 children with ADHD aged 8 to 12 who did judo for 2 hours a week over three months improved their visual working memory compared with a waitlist group; the authors suggest judo may complement medication. A 2025 review of 11 studies found gains in attention, working memory and self-control, most clearly with judo and taekwondo.
None of this makes martial arts a therapy, and it isn’t medical advice. To find a good fit, tell the school about your child before the trial, and look for small classes, a predictable routine, instructors who demonstrate rather than just explain, and a place to take a break. Ask about loud shouts, mats and uniform fabric if your child is sensitive to them. Some schools run adaptive classes or private lessons. In California, regional centers can fund social recreation such as martial arts lessons; ask your service coordinator (see our guide to regional centers in Los Angeles).
Is martial arts safe for kids? Sparring, gear and injuries
Mostly, yes. The AAP’s parent guide (2025) says injury rates for children in martial arts are low and most injuries are mild: cuts, scrapes, sprains and overuse injuries. Contact adds bruises, fractures and concussions. A 2023 study of U.S. emergency rooms estimated about 177,000 children aged 3 to 17 were treated for martial arts injuries from 2004 to 2021, most often sprains and strains, and found that competition carried about 2.6 times the risk of head and neck injuries of classes and other activities.
- Skills before sparring. Kids should learn forms and technique without contact first; there’s no set age when they’re ready to spar.
- Gear helps, but not with concussions. Headgear, mouthguards and pads protect against cuts and dental and soft-tissue injuries, but no protective equipment has been shown to prevent concussions.
- Head contact should be discouraged for children, and instructors should stress technique and self-control.
- MMA competition should generally be discouraged for young participants, the AAP says.
- Clean mats. Kids train barefoot, so mats should be in good shape and cleaned to stop infections spreading.
If your child has a health condition or has had a concussion, talk to their pediatrician before they start a contact class.
Questions parents ask
What is the best martial art for kids?
There isn’t one best style; the best one is taught well at a school near you. If your child loves to kick and likes clear steps, try karate or taekwondo. If they like wrestling and working things out with a partner, try Brazilian jiu-jitsu or judo, which teach control without blows to the head. Watch a class at two or three schools, take the free trials, and pick the instructor your child listens to.
What age can kids start jiu-jitsu?
Most jiu-jitsu academies open kids’ programs between ages 4 and 6, and the IBJJF’s kids’ belt system starts at 4, with grey belts for ages 4 and up. Classes for 3- and 4-year-olds are mostly guided play: tumbling, games and balance. Readiness matters more than the birthday: a child who can follow directions, take turns and reset after a mistake is ready for a structured class. It’s never too late to start.
Karate vs taekwondo: which is better for kids?
Neither is better; they’re more alike than different. Both are striking arts with belts, forms and a focus on respect and self-control. Taekwondo leans on kicks, including high and spinning ones, and is an Olympic sport; karate puts more weight on hand strikes and strong stances. For a young child, the instructor and the class structure matter far more than the style, so compare schools, not names.
Taekwondo or jiu-jitsu: which should my child do?
They’re different sports. Taekwondo is a striking art: kicks, forms and, later, padded sparring, with clear belt steps and Olympic competition. Jiu-jitsu is grappling: no punches or kicks, and kids practice holds and escapes against a resisting partner from early on. A child who loves to move and kick may enjoy taekwondo; one who likes wrestling and problem-solving may prefer jiu-jitsu. Try a class of each.
Is karate good for kids with autism?
It can be. Small studies of martial arts programs for children with autism have found better balance, coordination and executive functioning, and a 2025 review of karate kata and tai chi studies found improved coordination and balance, though the research is still limited. What matters most is the class: small groups, a predictable routine, an instructor who adapts, and room for breaks. Ask about adaptive classes or private lessons, and take a trial first.
How long does it take a child to get a black belt?
It depends on the style and the school, and children often get a junior version. In taekwondo’s Kukkiwon system, a black belt earned before 15 is a junior poom rank. In Brazilian jiu-jitsu, IBJJF rules don’t allow a blue belt before 16 or a black belt before 18. Be wary of any school that guarantees a black belt or sells one on a fixed timeline: promotions should follow skill and time on the mat.
Is MMA safe for kids?
The American Academy of Pediatrics says competitive mixed martial arts carries a relatively high risk of serious injury and should generally be discouraged for young athletes. Some gyms’ kids’ MMA classes are really drills in striking and grappling without fights, which is a different thing. Ask what children actually do in class, whether there is any sparring or contact to the head, and how the coach decides a child is ready.
How we made this list
We searched the web (Exa) for kids’ martial arts styles, costs, safety and research, then read the governing bodies’ pages (IBJJF, USA Judo, USJF, USA Taekwondo), the American Academy of Pediatrics’ guidance, the studies cited and schools’ own price pages in October 2026. Prices are what individual schools post, not national averages. We left out schools’ marketing claims we couldn’t check and anything aimed only at adults.
No one paid to be on it. It’s information to start from, not medical or legal advice: check services, costs and coverage with each provider before you book. Spotted something out of date, or run a place that belongs here? Write to hello@summerground.com.
