Why BJJ Gi Sizing Matters

A well-fitted gi is much more than a uniform—it’s your armor, your training partner, and your first line of defense against discomfort and distraction. The right size ensures you can move freely, execute techniques efficiently, and avoid giving your opponent unnecessary grips. An ill-fitting gi can hinder your performance, restrict your movement, or even get you disqualified in competition due to rule violations.

Understanding BJJ Gi Sizes

BJJ gi sizes are unique compared to other martial arts uniforms. Instead of standard clothing sizes, BJJ gis are labeled with codes like A0, A1, A2 (for adults), F1, F2 (for women), and K0, K1, M0, M1 (for kids). Each code corresponds to a range of height and weight, but every brand interprets these codes a bit differently.

General BJJ Gi Size Chart (Adults)

Size	Height (ft/in)	Weight (lbs)
A0	5’0″–5’4″	95–120
A1	5’4″–5’8″	120–155
A2	5’8″–6’0″	155–190
A3	6’0″–6’3″	190–225
A4	6’2″–6’4″	225–250
A5	6’4″–6’7″	250–280
A6	6’6″+	280+

Always check the specific brand’s chart before buying, as there are variations.

How to Measure Yourself for BJJ Gi Sizing

To find your perfect BJJ gi size, grab a tape measure and follow these steps:

Height: Stand barefoot against a wall, back straight. Measure from the top of your head to the floor.
Weight: Use a reliable scale.
Chest & Waist: Some brands recommend these for a more tailored fit.
Arm Length: Measure from shoulder to wrist.
Inseam: Measure from crotch to ankle.

Once you have your numbers, compare them with the brand’s size chart.

How Should a BJJ Gi Fit? (BJJ Gi Sizing Best Practices)

A properly sized gi should:

Allow full range of motion without being baggy.
Have sleeves that reach the wrist bone when arms are extended.
Have pants that end just above the ankles.
Not restrict movement in the shoulders, hips, or knees.
For competition, meet IBJJF rules: sleeves within 5cm of the wrist, pant legs within 5cm of the ankle.

A gi that’s too tight restricts movement and may tear. A gi that’s too loose gives your opponent extra material to grip.

How to Avoid Shrinkage Issues

Shrinkage is a common concern—especially with cotton gis. Here’s how to keep your gi fitting perfectly:

1. Wash in Cold Water:
Hot water causes fibers to contract. Always use cold water (below 30°C/86°F).

2. Air Dry Only:
Avoid tumble dryers. Hang your gi to dry naturally.

3. Use Mild Detergent:
Harsh chemicals weaken the fabric.

4. Avoid Bleach & Fabric Softeners:
These damage fibers and can cause extra shrinkage.

5. Choose Pre-shrunk or Blended Fabrics:
Many brands now offer pre-shrunk gis or cotton-poly blends that shrink less.

6. Follow Brand Care Instructions:
Some brands, like those in the elite BJJ gi size chart or adidas BJJ gi size chart, are pre-shrunk but can still shrink a little if not cared for properly.

Special Considerations: Women’s and Kids’ BJJ Gi Sizing

Women’s gis often use F sizes (F1, F2, etc.) and are cut for a more contoured fit at the chest, waist, and hips4 6. Kids’ gis use K or M sizes and are based on age, height, and weight8.

BJJ Gi Youth Size Chart Example:

Size	Age	Height (ft/in)	Weight (lbs)
K0	4–6	3’3″–4′	30–50
K1	7–8	4’–4’3″	50–60
K2	9–10	4’3″–4’6″	60–80
K3	11–12	4’6″–5′	80–110

What If You’re Between Sizes?

If you’re between sizes, consider your body type and personal preference. If you prefer a snug, competition-style fit, go with the smaller size. If you want more room for movement or anticipate shrinkage, size up.

How to Try On and Adjust Your BJJ Gi

When you receive your gi:

Try it on before washing.
Check sleeve and pant length.
Move through basic BJJ movements (shrimping, bridging, guard retention) to test mobility.
If it’s too big, you may be able to shrink it slightly with a warm wash and low tumble dry—but do this cautiously.
