Finding the perfect fit for your Brazilian Jiu-Jitsu (BJJ) gi is essential for your comfort and performance on the mat. A well-fitted gi not only enhances your mobility but also ensures that your movements and techniques are executed smoothly. This article will guide you on how to measure yourself to find the perfect BJJ gi fit.

Understanding Gi Components and the Importance of Proper Fit

Gi Jacket

The gi jacket is the most significant part of a BJJ uniform. It is commonly made from durable, woven fabrics designed to withstand rigorous gripping and pulling. Some of the critical aspects to consider when finding a fitting gi jacket are the sleeves, hem, and lapel.

Sleeves: Ideally, the sleeves of your gi jacket should reach just past your wrists, allowing for a full range of motion without excess material getting in the way. Sleeves that are too long can be cumbersome and lead to unintentional rule violations in competition, while short sleeves may restrict your movements.

Hem: The hem of your gi jacket should fall just below the hip. The length impacts how easily your training partners can grip your jacket and also your range of motion.

Lapel: The lapel is the reinforced collar of your gi jacket, which plays a crucial role in lapel chokes and grip fighting. A well-fitted lapel should fit loosely around your neck but not overly tight, allowing for comfortable movement and regular breathing.

Gi Pants

In addition to the gi jacket, a well-fitted pair of gi pants is essential for optimal performance in BJJ. Key factors to consider when determining an ideal gi pants fit include the waist, pants length, and overall comfort.

Waist: The waist should fit comfortably around your hips, allowing for fluid movement without sliding down or feeling too tight. Most gi pants come with drawstrings to provide an adjustable fit.

Pants Length: Proper pants length is crucial for unrestricted movement during training. The ideal length should fall just above your ankle bone. Pants that are too long can get caught or stepped on during practice, while short pants may hinder your range of motion.

Comfort: Above all, your gi pants should feel comfortable when worn. They should allow for a wide range of movement, enabling both standing and ground techniques without restriction. The material and fit should provide adequate space as well as support.

In conclusion, finding the perfect fit for both your gi jacket and pants is crucial for comfort, movement, and performance in BJJ. By understanding the significance of each component and paying attention to essential factors, you can ensure that your gi will contribute positively to your training experience.

How to Measure Yourself for a New BJJ Gi

Tools Needed for Measuring

To measure yourself accurately for the perfect BJJ gi fit, you will need a few tools:

  • Soft measuring tape
  • Notebook or a piece of paper
  • Pen or pencil
  • Scale

Ensure the measuring tape is flexible and not stretched out, as it should comfortably wrap around the body parts you’ll be measuring.

Measuring Height and Weight

Start by measuring your height and recording your weight. These two measurements are essential when determining your BJJ gi size:

  1. Height: Stand against a wall with your feet flat on the ground. Mark the top of your head on the wall and measure the distance from the floor to the mark. Record your height in inches or centimeters.
  2. Weight: Use a reliable scale to measure your weight. Ensure you’re wearing minimal clothing and no shoes.

Measuring Chest and Waist

Next, measure your chest and waist to help find a BJJ gi that fits comfortably on your upper body:

  1. Chest: Wrap the measuring tape around the fullest part of your chest. Keep the tape horizontal and snug but not too tight. Record the measurement.
  2. Waist: Measure around your natural waistline, usually at the level of your belly button. Keep the tape horizontal and slightly snug. Record the measurement.

Measuring Arms and Legs

Finally, measure your arm length (wingspan) and leg length to ensure the BJJ gi sleeves and pants are the proper length:

  1. Arm Length (Wingspan): Stand with your arms outstretched to the sides. Have someone measure the distance from the tip of one middle finger to the other with the measuring tape. Record the measurement.
  2. Leg Length: Measure the distance from your waistline (where you measured earlier) to the floor while standing up straight. This will give you an approximation of the BJJ gi pants length. Record the measurement.

After taking these measurements, refer to the BJJ gi manufacturer’s size chart to find the ideal fit. Keep in mind that each brand may have different sizing, so always double-check their charts. With the correct measurements, you’ll be on your way to finding the perfect BJJ gi fit.

Importance of Perfect Gi Fit

A perfect fit for a Jiu-Jitsu gi plays a crucial role in the overall performance and comfort of the practitioner. Gis that properly fit the wearer allow for greater freedom of movement, improving their range of motion and facilitating more efficient techniques.

Comfort is a vital consideration when selecting a BJJ gi. Training sessions and competitions often last for extended periods, and an uncomfortable gi can hinder an athlete’s performance. A well-fitting gi ensures that the practitioner can focus on their techniques and strategies rather than adjusting their attire.

The range of motion in a gi directly impacts a practitioner’s ability to execute techniques effectively. A poorly fitted gi may be too tight in the torso, which can restrict movement and prevent the wearer from achieving their full potential. Conversely, a gi that’s too loose can be cumbersome and slow down a person’s movements, making them less precise and agile.

Different BJJ Gi Sizes and Styles

Sizing Charts

When looking for the perfect BJJ gi fit, it’s essential to consult sizing charts specific to the brand you’re interested in. Sizes can vary between different manufacturers, making it necessary to check each brand’s unique chart. An extensive collection of BJJ gi size charts, including popular brands like Fuji, Inverted Gear, Hyperfly, Gameness, and Sanabul can be found at BJJ GI Size Charts and Selecting the Right Gi.

In most cases, gi sizes range from A0 to A6 for adults, and F0 to F6 for women. Sizing Charts for Kids’ gis have there own system. To find the right size, measurements of your height, weight, and body type are generally required. Accurate measurement ensures the gi will be comfortable during training and competition while avoiding issues with excessive tightness or looseness.

Size and Style Differences

Each BJJ gi brand might offer unique size and style variations to cater to different preferences. Apart from the standard sizing, some brands provide options for tall (designated by a “T”), short (designated by an “S”), or long (designated by an “L”). These modified sizes accommodate distinct body proportions and help practitioners find a gi that gives them the comfort and mobility they need.

Style differences between BJJ gis can manifest in various aspects, such as the fabric weight, weave, collar thickness, and overall design. Some practitioners prefer lighter gis for increased mobility and comfort during training, while others opt for heavier, more durable gis to enhance their performance in competitions.

In summary, to ensure the perfect BJJ gi fit, consult brand-specific sizing charts, measure yourself accurately, and consider different size and style options. It’s crucial to strike a balance between comfort, mobility, and durability for a seamless training and competition experience.

Factors Affecting Gi Fit

When selecting the perfect BJJ gi, several factors contribute to finding the ideal fit. Understanding these factors will help you make an informed decision and ensure your gi feels comfortable during training and competitions.

Shrinkage is a common concern when purchasing a BJJ gi. Many gis are made from cotton, which tends to shrink after washing. It’s essential to consider how much a gi might shrink before buying. Some gis undergo a pre-shrunk treatment that minimizes shrinkage, while others may require a few washes to determine their final size.

Washing your gi also plays a role in its fit. Manufacturers provide care instructions to guide proper washing and drying techniques to maintain the gi’s intended size. Washing in cold water and hang-drying your gi are recommended ways to prevent excessive shrinking.

The way a gi fits can also be affected by adjustments made by the individual wearing it. Gis come with a variety of options for adjusting the fit, such as drawstring pants and the placement of belt loops. Be sure to consider these factors and your personal preferences when selecting a gi.

In conclusion, finding the perfect BJJ gi fit depends on a combination of factors, including shrinkage, washing, adjustments, and individual preferences. Take the time to understand these aspects and choose a gi that matches your needs for both comfort and performance.

Testing Your Gi Fit

When selecting the perfect BJJ gi, it is important to test its fit to ensure comfort and optimal performance during martial arts practice. Here is how to test your gi fit properly:

1. Free Movement and Range of Motion

A good gi should allow for free movement and a full range of motion. To test this, wear your gi and perform some BJJ drills or general exercises such as lunges, squats, or rolls. If you experience any restriction or discomfort, it might be a sign that the gi is too small or too tight in certain areas.

2. Resistance to Pulling and Tugging

Gis are subjected to constant pulling and tugging during practice and competitions. To test the resistance of your gi, ask a training partner to firmly pull on the collar, sleeves, and pants. The fabric should be strong enough to withstand this stress without tearing or losing its shape.

3. Adequate Coverage

Your gi should provide adequate coverage to prevent any unwanted exposure during practice. Check for gaps or areas that may become exposed when executing various movements. This includes the collar area, waist, and thigh areas. Proper coverage ensures both comfort and respect for your fellow practitioners.

4. Assessing the Sleeves and Pants Length

To ensure your gi is the right size, the sleeves should reach just below your wrists when your arms are extended, and the pants should reach just below your ankles. This length provides optimal coverage and mobility while reducing the risk of getting caught on an opponent’s limbs or clothing.

By taking the time to test your gi fit, you can ensure you make the best choice for your martial arts practice and enjoy greater comfort, mobility, and performance.

Common Issues and Solutions

When purchasing a BJJ gi, it’s essential to find the perfect fit to ensure comfort and performance during training and competition. Here are some common issues and their solutions:

Too tight or too small: If the gi feels too tight and restricts your movement, it could be problematic and uncomfortable during training. Try going up a size or looking for a gi with a different cut designed for your body type. Remember, it’s essential to consider the gi’s shrinkage after washing.

Too big: An oversized gi can make it challenging for you to execute techniques and provide your opponents with additional grip material. To resolve this issue, try exchanging the gi for a smaller size or a different brand with a cut that suits your body better. Again, keep in mind that most gis will shrink after washing in warm water, so choose a size that allows for this.

Returning gis: Most companies have return policies, usually 30 to 60 days from the purchase date. If you bought the gi online, ensure that you keep the original packaging and tags in good condition to facilitate a smooth return process. Also, follow the specific return instructions provided by the seller.

Finding the perfect BJJ gi fit might require some trial and error, but by considering these common issues and solutions, you can feel confident and knowledgeable in your pursuit. Remember to prioritize comfort, functionality, and durability over style when measuring yourself and selecting the perfect fit.


Measuring oneself for the perfect BJJ Gi fit is essential for ensuring comfort and performance on the mats. Utilizing a sizing chart and size guide can make this process much easier and more accurate.

When taking measurements, it’s crucial to follow the correct steps, such as measuring the chest, waist, hips, inseam, and arm length. Following the manufacturer’s size guide will lead to a better understanding of which size and cut suits an individual’s body frame.

A well-fitted BJJ Gi allows for a better range of motion while training, leading to an improved learning experience, increased confidence, and a reduced chance of injuries. It is worth investing time and effort into finding the right size Gi to enhance one’s BJJ journey.
