The term "weight" in the context of T-shirts typically refers to the thickness or heaviness of the fabric used in the shirt. This is often measured in ounces per square yard (oz/yd²) or grams per square meter (g/m²).

The weight of a T-shirt can influence its durability, comfort, and suitability for different weather conditions and fashion style. Here are some common weight categories for T-shirts:

1. Lightweight T-shirts (3-4 oz/yd²)(80-120 gsm):

   • These T-shirts are typically lighter and suitable for warmer weather.
   • They are comfortable and breathable but may be less durable compared to heavier options.

1. Midweight T-shirts (5-6 oz/yd²)(140-170 gsm):

   • Midweight T-shirts strike a balance between light and heavy options.
   • They are versatile and can be worn in various weather conditions.

1. Heavyweight T-shirts (7 oz/yd² and above)(200 gsm and above):

   • Heavyweight T-shirts are thicker and more durable.
   • They are often preferred for colder weather or for individuals who prefer a sturdier feel.

The weight of a T-shirt can affect how it drapes on the body, how warm or cool it feels, and how well it holds up to repeated washings. Keep in mind that these weight categories are general guidelines, and the actual feel and quality of a T-shirt can also be influenced by factors such as the type of fabric used (e.g., cotton, polyester, blends), the weave, and the overall construction. Additionally, personal preferences play a significant role in choosing the right weight for an individual's comfort and style.
