Online Shop Size Guides

We understand that choosing the perfect size clothing online can be challenging. Since there is no standardised sizing, one manufacturer’s size “L” can be another manufacturer’s size “M.” To help, we’ve compiled a list of Sheffield & Rotherham Wildlife Trust’s most popular clothing items and created a full measurement guide to help you find the perfect fit the first time.

Our garments are “true to size” as defined in the below size guides. We recommend referring to the sizing information before purchasing to ensure the correct fit. If you prefer a looser fit, we advise ordering a size up.

T-Shirts

If in doubt with sizing:

  • Grab your current favourite T-Shirt that fits you best.
  • Lay it out flat.
  • Measure according to the below diagram and refer to the charts underneath:
    • Measure horizontally directly across the front of your T-shirt, from just below the sleeve seam straight across to the same location on the opposite side (A). Make a note of the length in centimetres. This will give you your Half Chest size to compare to the below chart.
    • Optionally, measure the Body Length of the T-Shirt (B), and the Sleeve Length (C).

All garment sizes are approximate and for guidance only. Note: Larger sizes may only be available in limited colours.
