Explanation of the Sizes:

  • M0 / F0: Small children or petite adults (such as women under 5'0"). Boys and girls in this range will typically be younger and lighter.
  • M1 / F1: This size fits younger teens (typically 5'0" to 5'4") and smaller adult women or men. Often the most common size for small adults.
  • M2 / F2: Ideal for teens and smaller adult women who are between 5'3" and 5'6". This size range is also suitable for adult men who are medium build.
  • M3 / F3: Typically fits adults who are between 5'5" and 5'8" or women on the taller side (5'7" or above). Men with a muscular or larger frame who are around 170 to 200 lbs might also fit into this range.
  • M4 / A0: Larger teens or adults with a frame that falls in the 200-240 lb range. Taller adults might also opt for this size.
  • A1: This is one of the most common sizes for average adult men and women (typically 5'4" to 5'8", 155-190 lbs).
  • A2: Larger adults (5'8" to 6'0", 190-225 lbs). Often suitable for most adult males, but can also work for taller women in the same weight range.
  • A3: For taller and heavier adults, typically 6'0" – 6'2" and between 225-250 lbs.
  • A4: Larger adult sizes, typically for people over 6'0" and weighing between 250 and 300 lbs.
  • A5: The largest size for very tall and heavy adults, often over 6'3" and weighing over 300 lbs.

Women’s Gi Size (F sizes):

  • F0 - F3 are the most common women’s gi sizes, designed to fit the female form with shorter sleeves and a more tapered cut around the waist.
  • F sizes are typically best for women, but many women also choose unisex (A0, A1, etc.) gis if they prefer a looser fit or have a more muscular frame.

Key Points to Consider:

  1. Unisex vs. Women's Gi: If you prefer a more tailored fit that suits the female body, look for women’s cut gis (F0, F1, F2, F3). For more options, you can go for unisex sizes (A0, A1, etc.).

  2. Shrinkage: BJJ gis are often made of cotton, and most will shrink slightly after the first wash. Be aware of this when choosing your size—if in doubt, size up.

  3. Body Type: If you're between sizes or have a muscular frame, you might prefer going with a size up. Conversely, if you prefer a fitted gi, you might opt for a size down.

  4. Teenage Sizes: For young teens, sizes M0 to M2 are generally the best fit, while larger teens may wear a M3 or even an A0 if they're taller or heavier.
