Finding the perfect BJJ Gi fit can be tricky, especially if your Gi feels too big after purchase. While some BJJ Gis are pre-shrunk, others may require some adjustments to achieve the perfect fit. The good news is that you can shrink your BJJ Gi at home using simple methods.

At Novakik BJJ, we understand the importance of a well-fitted Gi for optimal performance, comfort, and mobility. This guide will show you how to shrink a BJJ Gi without damaging the fabric. Thus ensuring you get a perfect fit without compromising durability.

Why Would You Want to Shrink Your BJJ Gi?

There are several reasons why shrinking a Gi may be necessary:

• The Gi is too large after purchase – New Gis often come with extra room for shrinkage.
• Pre-shrunk Gis still shrink slightly – Even "pre-shrunk" Gis can loosen over time.
• You lost weight – If you've slimmed down, shrinking your Gi can make it fit better.
• Better performance & mobility – A well-fitted Gi improves your range of motion.
• Competition Fit – Loose-fitting Gis can be easier for opponents to grip, so competitors often shrink their Gis for a tighter fit.

But be careful! Shrinking a Gi too much can result in an overly tight fit, which may limit movement and make training uncomfortable.

How to Shrink a BJJ Gi (Step-by-Step Guide)

Before you begin, check if your Gi is pre-shrunk or made from a specific weave that resists shrinkage. If you are unsure, Novakik BJJ’s product descriptions provide details on shrinkage expectations.

Step 1: Wash Your Gi in Hot Water

• Use hot water (but not boiling!) to shrink your Gi.
• Set your washing machine to a hot cycle (around 140°F or 60°C).
• Wash the Gi alone to prevent color bleeding.

Warning: Too much heat can cause excessive shrinkage or damage the fabric. Start with one wash cycle before moving to Step 2.

Step 2: Dry Your Gi on High Heat

• Place your Gi in the dryer on a medium or high heat setting.
• Check the Gi every 5-10 minutes to monitor shrinkage.
• Remove the Gi when it reaches the desired fit and air dry the rest of the way.

Pro Tip: If you want to shrink only certain parts (like sleeves or pants), hang dry the rest of the Gi and only machine dry those areas.

Step 3: Spot Shrinking for Specific Areas

If only certain parts of your Gi need shrinking, target those areas instead of shrinking the whole Gi.

• For Sleeves: Dip them in hot water for 10-15 minutes, then tumble dry.
• For Pants: Soak only the pants in hot water and use a dryer on medium heat.
• For the Collar: Lay flat after washing to prevent over-shrinking.

Caution: Avoid excessive heat on the lapel area, as it may cause stiffness or warping.

Alternative Methods to Shrink Your Gi

1- The Boiling Water Method (Extreme Shrinking)

If your Gi is way too big, you can use boiling water to shrink it faster.

How to Do It:

• Boil water in a large pot and turn off the heat.
• Submerge the Gi for 5-10 minutes.
• Remove and air dry or tumble dry for additional shrinkage.

Only use this method if absolutely necessary, as it can cause uneven shrinkage or damage some fabric weaves.

2- The Sun-Drying Method (Gentle Shrinking)

If you don’t want to risk over-shrinking, sun-drying is a great alternative.

• Wash your Gi in warm water instead of hot.
• Hang it in direct sunlight to dry naturally.
• Sunlight naturally tightens fabric without causing damage.

Best For: Pre-shrunk or competition Gis that need minor adjustments.

How Much Will a BJJ Gi Shrink?

The amount of shrinkage depends on the fabric, weave, and washing method:

• Pre-Shrunk Gis: 2-5% shrinkage
• Pearl Weave Gis: 3-8% shrinkage
• Single Weave Gis: 5-10% shrinkage
• Gold Weave or Heavy Gis: 10-15% shrinkage (if not pre-shrunk)

Novakik BJJ’s lightweight Pearl Weave Gis are designed to shrink minimally. So they maintain a long-lasting fit without becoming too tight.

Avoid These Mistakes When Shrinking Your Gi

• Using boiling water for too long – Can warp fabric fibers.
• Over-drying – Can cause excessive shrinkage and stiffness.
• Shrinking multiple times – The Gi may become too small if shrunk repeatedly.
• Ignoring Gi care labels – Each Gi brand has unique shrinkage guidelines.

How to Maintain the Perfect Fit After Shrinking?

Once your Gi reaches the perfect size, follow these care tips to prevent further shrinkage:

• Wash in cold water to maintain size and prevent additional shrinking.
• Hang dry instead of using a dryer.
• Stretch slightly after washing if it shrinks too much.
• Store in a cool, dry place to prevent fabric tightening.

When to Replace Instead of Shrinking a Gi

If your Gi is too big even after shrinking, it might be time for a replacement. Here’s when to invest in a new BJJ Gi:

• The Gi shrinks unevenly after multiple attempts.
• It becomes too stiff or uncomfortable.
• The fabric starts thinning or tearing after repeated shrinking.
• You need a competition-fit Gi and your current Gi is still loose.

Top Pick: Novakik BJJ offers a range of pre-shrunk, competition-ready, and lightweight Gis that maintain their fit after multiple washes.
