American Kickboxing Rules vs International Rules — Complete Easy Guide
Kickboxing is one of the fastest-growing combat sports in the world. But not all kickboxing matches follow the same rules. If you are training, coaching, or planning to compete internationally, it’s very important to understand the difference between American Kickboxing Rules vs International Rules.
This article explains everything, including legal techniques, scoring, protective gear, and training tips — so you can avoid confusion and prepare correctly.
1. What do we mean by “American” and “International” rules?
- American Kickboxing (Full Contact):
American kickboxing started in the U.S. in the 1970s. It combines karate-style kicks with western boxing punches. Kicks are allowed above the waist only. No low kicks, no knees, no elbows. Fighters often wear long pants in traditional events. Clinching is not allowed. - International Rules:
International rules is a broad term that includes Low Kick, K-1, WAKO, IKF, and ISKA styles used around the world. These rules allow leg kicks, sometimes knees, and limited clinch depending on the organization. Fighters usually wear shorts.
In short, American kickboxing has stricter striking rules, while international styles offer more variety.
What is the difference between kickboxing and American kickboxing?
Many beginners ask: “What is the difference between kickboxing and American kickboxing?”
The answer is simple — American kickboxing is just one style within the wider world of kickboxing.
- Kickboxing (International): Includes many global styles such as Japanese kickboxing, Dutch style, K-1, and Low Kick. These usually allow leg kicks, sometimes knees and clinching, and have a broader range of techniques.
- American Kickboxing: Originated in the USA. It only allows kicks above the waist and bans leg kicks, knees, and elbows. It focuses more on fast boxing combinations and high kicks.
Main difference: Kickboxing (international) allows more striking options, while American kickboxing is limited to punches and above-the-waist kicks. This affects fight strategy, training methods, and competition style.
2. Legal target areas — key differences
- American Kickboxing:
- Punches and kicks are allowed above the waist only.
- Leg kicks, knees, and elbows are not allowed.
- Clinching is not allowed.
- International Rules:
- Low Kick rules allow kicks to the legs, body, and head.
- K-1 rules allow low kicks and short knees.
- Clinch depends on the style — K-1 allows brief clinch for one knee strike.
This is the main practical difference between American Kickboxing Rules vs International Rules. Leg attacks completely change the strategy of a fight.

4. Rounds, time, and match length
- American Kickboxing:
Amateur bouts typically have 2-minute rounds with 1-minute breaks. Number of rounds depends on level (3–10 rounds). - International Rules:
- Amateur bouts follow 2–3 minute rounds depending on the organization.
- Professional K-1 bouts are usually 3 rounds of 3 minutes.
- Championship fights can include extra rounds if there’s a draw.
International fights often feel faster and more intense due to leg attacks and knees.
5. Scoring differences
- American Rules:
Judges score based on clean punches and kicks to the body and head, aggression, and defense. Because there are no leg kicks, emphasis is on upper-body strikes. - International Rules:
Judges also score leg kicks, knees, and overall effectiveness. Leg damage can win rounds. Balanced high-low combinations score well.
Scoring criteria change strategy: In American rules, fighters rely on boxing and high kicks. In international rules, leg attacks and combinations are key.

- Gloves, headgear, mouthguard, groin protector, and sometimes foot pads are required.
- Amateurs usually wear shin guards.
- International Rules:
- Fighters wear shorts similar to Muay Thai.

- Shin guards are used in amateur fights; pros usually fight without them.
7. Safety and rule updates
Many international organizations update their rules regularly to improve safety. For example, WAKO Pro updated several international rules in 2025 regarding protective gear, weight classes, and judging criteria.
Always check the official rulebook of the event or federation (WAKO, IKF, ISKA) to avoid surprises on fight day.
8. Training differences for each style
- Training for American Kickboxing:
- Focus on boxing, high kicks, and fast footwork.
- No need for heavy shin conditioning.
- Defense revolves around body and head attacks.
- Training for International Rules:
- Learn to check and defend low kicks.
- Condition shins for leg kicks.
- Practice clinch control and knees if competing in K-1.
- Use more full-body striking combinations.
Training must match the ruleset. Don’t train only for American rules if you plan to fight under international rules.

9. Real event examples
- American Rules Events:
Many U.S. regional events, amateur tournaments, and some pro promotions still use classic American kickboxing rules. - International Rules Events:
Major tournaments like WAKO World Championships, K-1 Japan, Glory Kickboxing, and ISKA events follow international rules (Low Kick / K-1).
Before competing, always check the exact ruleset of the event.
10. Which ruleset should you choose?
It depends on your goals:
- Choose American rules if you prefer fast-paced, above-the-waist striking, or are transitioning from boxing or karate.
- Choose International rules if you want to compete globally or transition to MMA. Learning leg kicks and knees will give you a more complete striking game.
Both are effective, but they require different strategies and training.
