Choosing the correct Shoyoroll gi size is essential for training comfort, mobility, and competition legality. This complete guide walks you through every step — from measurement diagrams to a built-in size finder.

📘 1. How to Measure Your Body for a BJJ Gi

Below are the measurement steps.
(I will insert the corresponding diagrams once you’re logged in.)

📏 Step 1: Measure Your Height

Height is the most important factor in Shoyoroll sizing.

How to measure:

1. Stand against a wall.

2. Place a book flat on your head.

3. Measure floor to top of book.

⚖️ Step 2: Measure Your Weight

Weigh yourself barefoot.
Shoyoroll uses height + weight pairs to determine your base size.

📐 Step 3: Measure Your Wingspan

This helps determine whether you need Long (L) or Short (S) gi variants.

How to measure:

1. Stretch arms sideways (T-pose).

2. Measure fingertip to fingertip.

If wingspan > height: consider “L” variants
If wingspan < height: standard or “S”

📏 Step 4: Measure Chest Circumference

Used to determine if you need H (Husky) variants.
Measure around the widest part of your chest.

👖 Step 5: Measure Your Inseam

Ensures pant length is correct.

How to measure:

1. Measure from crotch to ankle bone.

🧼 Shrinkage Notes

Most Shoyoroll gis are pre-shrunk but still tighten ½–1 inch.
If you’re between sizes:

• Choose slightly bigger (you can shrink it)

• Avoid sizing down

🧩 2. Shoyoroll Size Finder (Interactive Logic)

Here is the interactive decision tree you can add to your website.
