All Blacks Jersey Size Guide: How to Find Your Perfect Fit
Buying your new All Blacks Replica Home Jersey should be exciting, and not a guessing game.
One of the most common questions we hear at RYOS is:
"What size All Blacks jersey should I buy?"
The good news is that choosing the right size is easier than you might think. By taking just a few simple measurements and comparing them with a favourite shirt or jersey you already own, you can order with confidence and enjoy the perfect fit the first time.
This guide explains exactly how we measure our jerseys, what the measurements mean, and how to choose the size that's right for you.
Understanding the All Blacks Jersey Size Chart
Every jersey is measured using three key dimensions:
- Half Chest
- Half Waist
- Length
All measurements are taken in centimetres (cm) with the jersey laid flat on a table.
These measurements provide a far more accurate guide than simply relying on Small, Medium or Large labels, which can vary significantly between clothing brands.
How We Measure Our Jerseys
To ensure consistency, every jersey is measured using the same method.
1. Half Chest
The half chest, or "pit-to-pit", measurement is taken straight across the jersey from one underarm seam to the other while the garment is laid flat.
This is the most important measurement when choosing your size.
2. Half Waist
The Half Waist is measured across the narrowest point of the jersey.
Like the chest measurement, this is taken with the jersey lying flat and represents half of the garment's total circumference.
3. Length
Length is measured from the highest point of the shoulder, next to the collar, straight down to the bottom hem.
As jersey sizes increase, both the width and length increase proportionally to maintain a comfortable fit.

The Easiest Way to Find Your Perfect Size
Instead of measuring yourself, we recommend measuring a shirt or jersey you already own and love wearing.
It's the quickest and most accurate way to find your ideal size.
Step 1 β Choose Your Favourite Jersey
Pick a rugby jersey, polo shirt or T-shirt that fits exactly the way you like.
Step 2 β Lay It Flat
Place it on a table or flat surface and smooth out any wrinkles.
Step 3 β Measure Three Areas
Using a tape measure, record:
- Underarm to underarm (Half Chest)
- Across the waist (Half Waist)
- Shoulder to bottom hem (Length)
Step 4 β Compare With Our Size Chart
Match those measurements to our sizing guide on the RYOS website and choose the closest size.Β
This method is much more accurate than guessing based on your usual clothing size.

Replica Jersey vs Player Jersey
One question we often receive is:
"Do replica jerseys fit the same as the jerseys the All Blacks wear on the field?"
The answer is no.
The All Blacks Replica Home Jersey is designed specifically for supporters and everyday wear.
That means you'll enjoy:
β A more relaxed fit
β Greater comfort throughout the day
β Plenty of freedom of movement
β Enough room to wear a thermal or T-shirt underneath during the colder months
Professional playing jerseys are designed to fit tightly to reduce grabbing during matches, whereas replica jerseys prioritise comfort for supporters.
Between Two Sizes?
If your measurements sit between sizes, here's a simple guide.
Choose the Smaller Size if you:
- Prefer a fitted look
- Don't intend to wear extra layers
- Are closer to the smaller measurement
Choose the Larger Size if you:
- Like a relaxed fit
- Plan to wear a thermal or base layer underneath
- Prefer extra room around the chest and shoulders
- Sit closer to the larger measurement
When in doubt, many supporters prefer sizing up for maximum comfort.
Understanding Half Measurements
One point that often confuses is that our sizing chart lists Half Chest and Half Waist measurements.
Because the jersey is measured flat, simply double these figures to estimate the full circumference.
For example:
- Half Chest = 56cm
- Approximate Chest Circumference = 112cm
Comparing these measurements to a jersey you already own remains the easiest and most reliable way to select the correct size.
Still Unsure?
That's what we're here for.
If you're uncertain about which size to choose, simply contact the friendly team at RYOS with your measurements.

Our goal is to make sure your new jersey fits perfectly from the moment it arrives.
