Understanding Kingz Sizes

A0 – A6 Adult Standard

The baseline scale for most practitioners. Higher numbers add room throughout — chest, sleeves, and pants. A0–A1 for lighter, slimmer frames; A2 is the most common size on the mat; A3–A6 for broader builds and taller athletes.

L Variant Long

Same torso width as the base size, with longer sleeves and pant legs. Built for tall, lean frames with long arms and narrow shoulders. An A2L fits tall and slim where a standard A2 would leave sleeves short.

H Variant Husky

Adds width through the chest, shoulders, and lapel without excessively long pant legs. Better for broader, thicker builds. An A2H fits someone shorter but heavier through the torso than a standard A2.

F Prefix Women's

Proportioned with narrower shoulders and a more tapered waist. Adjusts geometry, not quality. See the full Women's collection for gis built specifically to your structure.

M Prefix Youth

Scaled for younger practitioners without excess bulk. Sized to allow for growth over time — an important consideration for athletes training toward long-term goals on the mat.

How to Measure for the Right Size

Metric 01
Weight
Start Here — Always

Weight determines how the jacket wraps across your torso. It is the single most important measurement. If you are between two sizes, follow weight before height.

  • Too light → excess fabric gives opponents more to grip
  • Too heavy → lapels barely overlap; collar harder to secure
  • Correct → clean overlap, full shoulder rotation
Metric 02
Height
Fine-Tune Length

Height refines sleeve and pant length only. Once weight anchors the jacket size, height determines whether you pass competition inspection.

  • Sleeves should reach near the wrist bone, arms extended
  • Pants should rest just above the ankle
  • Too short risks failing IBJJF measurement checks
  • Too long invites grip control and entanglement
Metric 03
Wingspan
Often Overlooked

Arm length varies significantly among athletes of identical height. A longer wingspan means standard sleeves may come up short — even when weight and height align.

If your arms consistently feel short in standard cuts, L variants or bridge sizes close this gap at both training and competition level.

Tie-Breaker: When measurements leave you on the fence, let your game decide. Pressure passers and top players benefit from sizing down — less fabric for opponents to grip. Guard players, inverters, and dynamic movers benefit from sizing up — more freedom through hips and shoulders.

Note: Charts are a starting point — not a verdict. When measurements fall between sizes, consider L or H variants to dial in the fit, and always prioritize how the gi performs in live rounds over numbers on a page.

04

Shrinkage by Model

Partially Pre-Shrunk
3–5%

These models are pre-shrunk but not fully — expect some additional shrinkage with heat exposure. Cold wash and air dry to preserve the fit you selected.

Kore One Sport Comp 450 Classic Empowered
Fully Pre-Shrunk
1–2%

These models are fully pre-shrunk and hold their original dimensions reliably. Minimal additional shrinkage expected even with regular washing.

Ultralight Balistico

Care Rule: Cold water and air drying preserve the fit you selected regardless of model. Heat changes cotton — even in pre-shrunk gis. You can shrink a slightly large gi down, but you cannot reverse one that's too small. For the first few washes, stay disciplined and let the fabric settle naturally.

Common Sizing Questions

What if I'm between two sizes?
Follow your weight first. If you're lighter for your height, consider L variants. If broader or heavier, an H variant will provide a more accurate, competition-safe fit. When all else fails, sizing up is the safer choice — you can shrink a slightly large gi, but you cannot reverse one that's too small.
Should a new gi feel tight or loose?
Close but not restrictive. Expect slight shrinkage after the first few washes. Sleeves and pants should sit near wrists and ankles without limiting shoulder or hip movement. If it feels confined on the rack, it will only get worse after washing.
How much will my Kingz gi shrink?
It depends on the model. The Kore, One, Sport, Comp 450, Classic, and Empowered are partially pre-shrunk and may shrink 3–5% with heat exposure. The Ultralight and Balistico are fully pre-shrunk and will shrink no more than 1–2%. Cold washing and air drying minimize changes across all models.
Is it better to size up or size down?
If unsure, size up. A slightly large gi can be shrunk into shape. A gi that is too small will remain restrictive and may fail IBJJF measurement standards at competition. Your game style can serve as the deciding factor — see the tie-breaker note in Section 02.
Do Kingz gis fit differently than other brands?
Yes. Cut, weave, and manufacturing tolerances vary between brands. Always compare your measurements to the Kingz size chart for the specific model you are purchasing, rather than relying on your usual size from another brand.
