If you’re into Brazilian Jiu-Jitsu or other martial arts, then you know how important it is to have a good gi. Not only does it look stylish, but it also helps you perform better during training or competitions. However, one downside of gis made of cotton or other natural fibers is that they tend to shrink. But, just how much do tatami gis shrink? The answer may surprise you.
First, it’s important to note that tatami gis are known for their high quality and durability. They are made of a heavy weave cotton fabric that is both comfortable and sturdy. However, like most gis, they are prone to shrinking after washing. But, just how much? On average, tatami gis can shrink anywhere from two to four inches in length and one to two inches in width. This may not seem like a lot, but it can make a big difference in how the gi fits and feels.
So, what can you do to prevent your tatami gi from shrinking too much? The key is to follow proper washing and drying instructions. Always wash your gi in cold water and avoid using high heat in the dryer. You can also hang dry the gi to prevent any additional shrinkage. By taking care of your tatami gi properly, you can ensure that it will last for years to come, even with the inevitable shrinking that may occur.
Factors Affecting Gi Shrinkage
When purchasing a Tatami Gi, it is important to understand how much the Gi will shrink after washing and what factors can affect shrinkage. This information can help you choose the correct size and avoid the frustration of an ill-fitting uniform. Below are some of the main factors that influence Gi shrinkage:
- Material: The type of fabric used to make the Tatami Gi can significantly impact how much it will shrink. Cotton is a common material for Gis and tends to shrink more than synthetic materials.
- Weave: The weave of the fabric can also have an effect on shrinkage. For example, a tight weave like a Honeycomb or Rice Grain will shrink less than a looser weave like a Diamond or Single.
- Construction: The way the Gi is constructed can also impact shrinkage. A single weave Gi will typically shrink more than a double weave, and a pre-shrunk Gi will obviously shrink less than one that has not been pre-shrunk.
- Washing: The way you wash your Tatami Gi can also make a difference in shrinkage. Hot water and high heat in the dryer will cause more shrinkage than cold water and air drying. Additionally, washing with other clothes and using fabric softener can cause more friction and shrinkage.
It’s important to note that while some factors may be within your control (such as washing), others are not (such as material and weave). It’s always a good idea to check the manufacturer’s recommendations for washing and drying, and to look for reviews or feedback from other customers on how much shrinkage to expect.
Pre-Shrunk vs. Non Pre-Shrunk Gis
One of the biggest factors affecting Gi shrinkage is whether or not the Gi has been pre-shrunk. Pre-shrunk Gis have gone through a process that causes them to shrink before they are sold, reducing the amount of shrinkage you experience after washing. Non pre-shrunk Gis, on the other hand, have not gone through this process and will shrink significantly after the first wash.
To determine if a Gi is pre-shrunk, look for keywords in the product description such as “pre-shrunk,” “minimal shrinkage,” or “sanforized.” If the manufacturer does not specify, it’s best to assume that the Gi will shrink and order a size up if you are in-between sizes.
Shrinkage Chart
To help you determine how much a Tatami Gi will shrink after washing, we’ve compiled a general shrinkage chart based on our experience and customer feedback:
| Material | Shrinkage After First Wash |
|---|---|
| Cotton | 5-10% |
| Polyester/Cotton Blend | 3-5% |
| Rayon/Cotton Blend | 8-12% |
| Bamboo/Cotton Blend | 3-5% |
Keep in mind that these numbers are estimates and can vary based on the other factors listed above. It’s always a good idea to do a test wash on a small piece of fabric before washing the entire Gi to see how much it will shrink.
Pre-Shrunk vs. Non Pre-Shrunk Gis
One of the biggest concerns for practitioners when investing in a new gi is how much it will shrink after washing. The amount of shrinking can determine if the new gi will fit correctly or not. Therefore, it is important to understand the differences between pre-shrunk and non pre-shrunk gis.
- Pre-Shrunk Gis: As the name suggests, pre-shrunk gis are made of fabric that has been treated before being cut and sewn. The treatment involves washing and drying the fabric to eliminate any further shrinking. This means that pre-shrunk gis will not shrink much, if at all.
- Non Pre-Shrunk Gis: On the other hand, non pre-shrunk gis are made of fabric that has not been treated prior to being cut and sewn. This means that once washed, non pre-shrunk gis will experience significant shrinkage. In fact, non pre-shrunk gis are known to shrink up to two sizes smaller after the first wash.
Non pre-shrunk gis may seem like a risky investment since they will shrink by such a large amount. However, many practitioners actually prefer non pre-shrunk gis because they can fit perfectly after the initial shrinking.
It is important to note that the amount of shrinking also depends on the type of material used for the gi. The following table shows the shrinking percentage for different materials:
| Material | Pre-Shrunk Gi | Non Pre-Shrunk Gi |
|---|---|---|
| Cotton | 0-2% | 10-15% |
| Cotton-Polyester blend | 0-2% | 5-10% |
It is important to always follow the manufacturer’s instructions when washing your gi to prevent any unnecessary shrinkage. For non pre-shrunk gis, consider buying a size larger to allow for the initial shrinkage. And for pre-shrunk gis, you can confidently buy your regular size knowing that it will not shrink much if at all.
Proper Care for Your Tatami Gi
One of the most important aspects of owning a tatami gi is proper care and maintenance. Not only will taking good care of your gi help it last longer, but it can also prevent shrinkage. Here are some tips for caring for your tatami gi:
- Wash your gi in cold water: Heat can cause shrinkage, so it’s important to wash your gi in cold water. This will also help preserve the color of the fabric.
- Avoid the dryer: Instead of drying your gi in the dryer, hang it up to dry. This will prevent excess heat from shrinking the fabric.
- Use a gentle detergent: Avoid harsh detergents that can damage the fabric. Instead, use a gentle detergent specifically designed for delicate fabrics.
By following these tips, you can help prevent your tatami gi from shrinking. But what if your gi has already started to shrink? Here’s a handy table that shows how much you can expect your gi to shrink:
| Brand | Estimated Shrinkage |
|---|---|
| Shoyoroll | 3-5% |
| Kingz | 2-4% |
| Tatami | 2-3% |
It’s important to note that these are just estimates and your gi may shrink more or less depending on various factors such as water temperature and drying method. By taking good care of your tatami gi and following these tips, you can help prevent shrinkage and make sure your gi lasts as long as possible.
Common Misconceptions about Gi Shrinkage
One of the biggest concerns among martial artists and practitioners is the shrinkage of their gi after washing. It’s a common misconception that all gi will shrink the same amount, but this is simply not the case. Here we will debunk some of the myths around gi shrinkage:
- Myth #1: All gi shrink the same amount.
- Truth: Different brands and types of gi will shrink differently. This can depend on the quality of the fabric, the weave, and even the dye used on the gi.
- Myth #2: You can prevent gi shrinkage by always washing in cold water.
- Truth: Washing your gi in cold water can help to minimize shrinkage, but it will not prevent it entirely. Hot water and high heat in the dryer are the main culprits for significant shrinkage, but even cold washes can cause some shrinkage over time.
- Myth #3: If your gi shrinks, it’s ruined and you need to buy a new one.
- Truth: Mild shrinkage is normal and can even be expected with repeated washings. Depending on how much it has shrunk, you may still be able to comfortably wear the gi. If it has shrunk too much, you can try stretching it out while it’s wet or having it professionally tailored to fit you better.
Understanding Gi Shrinkage Rates
The amount of shrinkage will vary depending on the materials used to make your gi. The two main fabrics used in the making of gi are cotton and hemp. Cotton is the most common choice and will typically shrink around 10% after the first wash. Some brands of gi are pre-shrunk, meaning they have already undergone a special washing process that lessens the amount of shrinkage. Hemp gi, on the other hand, will typically shrink more than cotton gi, around 15% or more after the first wash. It’s crucial to check the care label of your gi to determine the recommended washing instructions since each brand may have different requirements for washing and drying.
| Type of Fabric | Average Shrinkage Rate (after one wash) |
|---|---|
| Cotton | 10% |
| Cotton (pre-shrunk) | 5-7% |
| Hemp | 15% or more |
The key takeaway is that while gi shrinkage is a common concern among martial artists, it’s important to understand that not all gi is made equally. Even within the same brand, different weaves or quality fabrics can lead to variations in the amount of shrinkage. Knowing how to properly care for your gi and the materials used to make it will help you make the most out of your investment and keep your gi in pristine shape for as long as possible.
Importance of Accurate Gi Size
When it comes to martial arts, the gi is an essential piece of equipment that needs proper sizing. A gi that is too small will restrict movement and be uncomfortable, while a gi that is too large will be cumbersome and impede performance. Here, we’ll discuss the importance of accurate gi sizing, and specifically, the amount of shrinkage that can be expected with tatami gis.
Factors That Affect Gi Shrinkage
- Fabric: The type of fabric used in the gi can affect how much it will shrink. Natural fibers like cotton and hemp tend to shrink more than synthetic fibers like polyester.
- Weave: The weave of a gi can also impact shrinkage. A looser weave will shrink more than a tight weave.
- Washing Method: The way you wash your gi will also affect how much it shrinks. Washing in hot water and drying on high heat will cause more shrinkage than washing in cold water and air-drying.
How Much Do Tatami Gis Shrink?
Tatami gis are known to shrink quite a bit, especially if they are made from 100% cotton. The amount of shrinkage can vary depending on the factors discussed above, but on average, expect a shrinkage of 2-5% in the length and 5-10% in the width. It’s important to keep this in mind when choosing the size of your gi and when caring for it to avoid excessive shrinkage.
Conclusion
Accurate gi sizing is crucial for any martial artist to perform at their best. Understanding the factors that affect gi shrinkage and how much it can occur, particularly in tatami gis, can help ensure you choose the right size and care for it properly to avoid unnecessary shrinkage and discomfort.
| Fabric Type | Shrinkage Range (Length) | Shrinkage Range (Width) |
|---|---|---|
| 100% Cotton | 2-5% | 5-10% |
| Cotton/Polyester Blend | 1-3% | 3-5% |
| 100% Polyester | Minimal to no shrinkage | Minimal to no shrinkage |

Alternatives to Traditional Tatami Gis
While traditional tatami gis have been used for centuries, they may not be the best fit for everyone. Here are some alternatives for those looking for something different:
- Lightweight Gis: If you’re looking for something that won’t weigh you down during training or competition, a lightweight gi may be the way to go. These gis are made from thinner material than traditional tatami gis, which makes them more breathable and allows for greater mobility.
- Rash Guard and Spats: For grapplers who prefer to train in something other than a gi, rash guards and spats provide great alternatives. They protect your skin from abrasions and infections, and the tight fit allows for easier movement and less grabbing by opponents.
- Short-Sleeve and Sleeveless Gis: If you train in a hot climate or just prefer to have more freedom of movement, a short-sleeve or sleeveless gi might be the perfect solution. These gis provide the same benefits as a traditional gi, but with less material restricting your movements.
Shrinkage Rate of Tatami Gis
It’s important to note that traditional tatami gis are known for their high shrinkage rate, meaning they will shrink significantly after their first wash. While this might seem like an inconvenience, it’s actually part of the process to help the gi fit better and last longer.
To get a better idea of how much a tatami gi will shrink, take a look at the following chart:
| Gi Size | Pre-Wash Length (cm) | Post-Wash Length (cm) | Shrinkage (cm) |
|---|---|---|---|
| A0 | 160 | 142 | 18 |
| A1 | 170 | 150 | 20 |
| A2 | 180 | 158 | 22 |
| A3 | 190 | 168 | 22 |
| A4 | 200 | 179 | 21 |
It’s important to keep this shrinkage rate in mind when selecting the size of your tatami gi. While it may be tempting to choose a larger size, remember that it will shrink significantly and could end up being too small after the first wash.
Best Brands for Minimal Shrinkage Gis
When it comes to choosing a gi that won’t shrink too much, it’s important to consider the brand and the materials used in the construction. Here are some of the best brands for minimal shrinkage gis:
- Shoyoroll
- Aesthetic
- Tatami Fightwear
- War Tribe
- Killer Bee
- Break Point
- Fuji
These brands are known for their high-quality gis that are made from durable and shrink-resistant materials. However, it’s important to note that even gis from these brands may shrink to some extent, especially if they are not cared for properly.
One thing to look for in a gi that won’t shrink too much is pre-shrunk fabric. This means that the fabric has been treated in a way that prevents significant shrinkage during washing. Some gis are also made from fabrics that are inherently less likely to shrink, such as bamboo or hemp.
Shrinkage Rate by Brand
| Brand | Shrinkage rate in % after 3 washes |
|---|---|
| Shoyoroll | 2-3% |
| Aesthetic | 2-3% |
| Tatami Fightwear | 3-4% |
| War Tribe | 3-4% |
| Killer Bee | 4-5% |
| Break Point | 4-5% |
| Fuji | 5-6% |
Of course, the amount of shrinkage depends on a number of factors, including the specific style and materials used in the gi, as well as the washing and drying methods employed. Ultimately, the best way to minimize shrinkage is to follow the manufacturer’s care instructions carefully, and to avoid exposing the gi to high heat or harsh detergents.
