The tables above provide a Universal Jumper Size Chart for Men, Women, Junior, and Youth, covering sizes from Junior Small through to Adult 3X-Large. It is designed to give you a clear overview of typical jumper sizing based on chest, bust, waist, and hip measurements, with UK, EU, and US conversions included. This makes it easier to find the right fit across age groups and international standards when shopping online.

However, please note that sizing can vary slightly between brands, so this chart should be used as a general reference only. If a specific product has a brand-supplied size guide, you’ll find it listed in the product description—we recommend referring to that first for the most accurate fit.

Considering More Than Just Size

In addition to measurements, it is also important to consider the fabric, cut, and intended use of the jumper. For example:

  • Cotton jumper – Comfortable and breathable, but may shrink slightly after the first few washes.
  • Wool or thermal jumper – Thicker fabrics that provide warmth, but often fit more snugly.
  • Stretch or blended fabrics – Designed with elastane or spandex for flexibility, which can affect how the jumper sits on the body.
  • Performance or athletic jumper – Often includes moisture-wicking fabrics, added stretch, or slim/tapered fits that influence overall comfort and movement.

Choosing the Right Size

  • If you’re between sizes or unsure, we generally recommend sizing up for added comfort.
  • This is particularly helpful for growing children, youth sizes, or when wearing fitted cuts or heavier fabrics.

Why This Guide Matters

We know that finding the right jumper size can sometimes be a challenge — especially with the wide range of brands, each using their own measurement systems. That’s why we’ve created this comprehensive  Jumper Size Chart Guide to help you make confident, informed decisions when shopping online with us.

Final Note

This general guide is a helpful starting point, but it’s important to remember that jumper sizes can vary slightly between brands, styles, and fabric types. Whenever possible, we strongly recommend checking the brand-specific size guides provided on our product pages for the most accurate fit.

✅ Pro Tips for Measuring Jumpers

  • Measure your chest or bust: Wrap a tape measure around the fullest part of your chest or bust, just under the arms. Keep the tape level and snug but not tight, and stand naturally.
  • Measure your waist (for fitted jumpers): Measure around the natural waistline, keeping the tape comfortably snug.
  • Check sleeve length: Measure from the shoulder seam down to the wrist, keeping your arm relaxed at your side.
  • Account for fabric shrinkage: Natural fabrics like cotton or wool may shrink slightly after washing.
  • When in doubt, size up: Especially for children, slim-fit cuts, or heavier fabrics, a slightly larger size improves comfort.

Brand-Specific Size Guides

On our website, you’ll find these brand-specific size guides directly under the product description on each product page. These charts are provided by the manufacturers and are the most accurate reference for that particular brand. If a brand-specific guide is listed, we encourage you to follow it rather than relying solely on this general chart.

Below is a list of brands currently stocked by A7 Sports, each offering its own brand-specific size chart for reference:
