Size Guide

How to Measure Correctly

The best way to find your size is to measure a shirt that already fits you well. Lay the shirt flat on a clean, hard surface and measure:

  • Chest width: Measure across the chest from armpit to armpit, then double the measurement to get the full chest circumference.
  • Length: Measure from the top of the shoulder (where the collar meets the shoulder seam) straight down to the bottom of the shirt.

Compare these two measurements with the size chart below. Choose the size that matches both your chest and length. If the two measurements fall into different sizes, prioritise the chest width — length can often be managed with washing or wear, but chest fit cannot.

Important: Asian Sizing Alert

Many football shirts, especially replica and retro editions, follow Asian sizing standards. Asian sizes run approximately one to two sizes smaller than European or North American sizing.

For example, an Asian XL may fit like a European M or L. Always check the measurements in the product description and compare them to your own measurements rather than relying on size names alone. When in doubt, order the larger size.

Fan vs. Player Fit: What's the Difference?

Jersey Lunatic stocks two versions of most shirts: the Fan version and the Player version. Understanding the difference will help you choose the right fit for your body and your preference.

Fan Version Player Version
Cut Relaxed, roomy, classic fit Tight, athletic, performance fit
Fabric Standard cotton or cotton blend Technical, moisture-wicking material
Ideal for Casual wear, everyday comfort Active wear, sports, gym, running
Sizing advice Order your usual size Size up one size from your usual

In practice: If you normally wear M in Fan version, try L in Player version. The Player shirt is cut for movement and built for speed — it will feel snug when you first put it on, but this is intentional. The fabric will stretch slightly with wear and movement.

Children's Sizes (Age-Based)

Children's sizing is based on age ranges and build. If your child is on the larger end of their age range or has a broader build, consider sizing up.

Final Tips

  • When in doubt, go larger. A shirt that is slightly too big can still look good and be worn comfortably. A shirt that is too small cannot be worn at all.
  • Personalised shirts cannot be resized. Once your name, number, and patches are added, the shirt is permanently yours. Measure twice before you order.
  • Washing may affect fit. Most football shirt fabrics will shrink slightly with hot water and the dryer. Wash in cold water and hang dry to preserve the original size. The Player version's technical fabric is more resistant to shrinkage than the Fan version's standard cotton.
  • Check the product description. Some items come from different manufacturers and may have unique sizing. Always read the notes in the product page.
