How we compare martial arts
Every style has loyal fans, and almost every school believes its own art is the right one for every child. Our job is to be the neutral voice in the lobby: to explain what each style actually involves for a child, where the styles genuinely differ, and which differences matter for which kind of child. This page explains how we do that.
The factors we compare
Each style profile and head-to-head guide looks at the same handful of things, so that one comparison can be read against another. We start with what a child actually does in class: striking, grappling or forms, and how much of each. Then we look at live practice, meaning how soon and how often children spar or roll against a resisting partner, because that shapes both self-defense value and how a child feels on the mat. We look at the usual starting age and at what a class for that age really looks like. We look at how belts and progress work, how long a junior black belt typically takes and whether testing carries extra fees. We look at safety, using published injury research where it exists and the rules each sport uses to protect children. And we look at cost, including the fees that do not appear in the monthly price.
The parent scorecard on each style page turns those factors into a quick visual. The scores are our editorial judgment of how the style typically works at a good children's program, not a measurement, and they are deliberately broad. A great karate school can teach better self-defense than a poor jiu-jitsu gym, and we say so wherever it matters.
Where the facts come from
Rules, belt systems, forms and curricula come from each style's main governing bodies, such as the Kukkiwon and World Taekwondo, the World Karate Federation, the International Brazilian Jiu-Jitsu Federation, USA Judo and USA Wrestling, and from the official competition rules for children. Safety statements rely on published medical and sports science research. Prices are typical ranges gathered from the published fees of schools across the United States, and we present them as ranges because they vary so much by city. Each guide lists its main sources at the end.
Independence
No school, franchise or equipment brand pays to be included, recommended or ranked on Belt & Mat, and we do not accept free classes or products in exchange for coverage. The site is supported by advertising, which is shown separately from our guides and never influences what we recommend. If we ever link to a product, we will say so clearly on that page.
Keeping guides current
Federations change rules, belt requirements and competition formats from time to time, and prices move every year. We review our guides regularly and show the date of the latest meaningful update at the top of each page. When a reader tells us something has changed, we check it and correct the guide.
Safety
Technique guides on this site are written to help families understand what a child is learning, not to replace an instructor. Children should practise kicks, throws, falls and sparring only under qualified supervision, and the advice of your child's instructor and doctor always comes first.
