T-Shirt Weight Guide 2022 (What You Should Know)

Weight is an essential factor in the quality and comfort of a T-shirt, yet many people overlook it. If you have a T-shirt business, it is necessary to understand.

In this guide, we’ll take you through what you should know about T-shirt weight in 2022.

The weight of a T-shirt depends on several factors, such as its size and cut, but most notably on the weight of the fabric used. Fabric weight is measured either in ounces (ounces per square yard) or GSM (grams per square meter). Heavier materials are typically thicker and more durable.

There’s a lot to understand about the suitability of different weights of T-shirt fabric for different styles of T-shirts. Because some manufacturers quote the weight of a shirt rather than the weight of the material, it can get confusing fast. Let us enlighten you.

The Effect Of Fabric Material On T-Shirt Weight

Manufacturers make T-shirt fabric from fibers spun into yarn and woven or knitted into fabric. The fibers can either be natural, synthetic, or blend the two. Manufacturers identify the material by weight (in grams per square meter or ounces per square yard) or thread count.

Thicker yarn results in thicker material, which is usually heavier than thinner material. However, synthetic fibers are often hollow and can be both thicker and lighter than thinner natural fibers.

How T-Shirt Fabric Weight Is Measured

The industry generally measures the weight of T-shirt fabric in metric units, grams per square meter (GSM).

Higher GSM values indicate thicker fabric, provided one is dealing with the same material. Do not compare polyester to cotton in weight, and expect to be able to infer differences in thickness.

Sometimes the fabric is still measured in ounces per square yard, sometimes simply called ounces.

A rough equivalence guide between ounces per square yard and grams per square meter is as follows:

Lightweight T-shirt fabric: 4 ounces per square yard/135 GSM

Medium weight fabric 5 ounces per square yard/170 GSM

Heavyweight (thick) fabric: 6 ounces per square yard (or more)/200 GSM (or more)

The Suitability Of Different Weights Of T-Shirt Fabric

The different weights of T-shirt fabric are suitable for different types of T-shirts. Let’s examine these differences.

Lightweight T-Shirt Fabric Is For Summer

Lightweight T-shirt fabric is thinner and lighter and is preferable for summer because it is often more breathable in hot weather. On rainy days, it may be more transparent. It dries more quickly but wrinkles more easily (especially cotton or linen) and may be prone to shrinkage.

Fabrics such as lyocell or rayon are less transparent than cotton in lightweights. It is lighter to ship and may therefore cost less to ship. A lightweight summer T-shirt will be made of 130-150 GSM fabric.

Two popular lightweight cotton t-shirts are Bella Canvas 3001 which is 4.2 oz/yd², and Next Level 3600 which is 4.3 oz/yd².

Medium Weight T-Shirt Fabric Is For Mid-Season

Medium weight T-shirt fabric is generally warmer than lightweight material, offering more protection from the wind and being less transparent, even when damp. It takes longer to dry but typically wrinkles less.

It makes for a good mid-season or year-round shirt and will be made of 160-180 GSM fabric.

The Gildan 5000 “Heavyweight” shirt is actually only a mid-weight 5.3 oz/yd² shirt.

Heavyweight T-Shirt Fabric Is For Winter

Heavyweight T-shirt fabric can vary in texture from soft and brushed to coarse. It tends to be opaquer. It takes longer to dry but is more resistant to shrinkage. Because they are warmer, they are more suited for cooler fall or winter weather or work wear.

Heavier shirts typically have sturdier stitching. They can go as high as 225 GSM in fabric weight.

The Gildan G200 Ultra Cotton T-shirt is a 6.0 oz/yd² heavyweight shirt.

Premium Weight T-shirts

Because higher GSM fabric takes more fiber to make, it costs more and is used for premium T-shirts.

This trend only holds good up to a point, with 160-180 GSM being the sweet spot for premium T-shirt fabric weight. Other factors such as fiber length will also play a role in determining whether or not a T-shirt is considered premium or not.

 Cheap promotional shirts designed to be worn only a few times will be around 100-110 GSM.

How Much Does a Hoodie Weigh?

In ounces, a standard hoodie weighs 16 oz. to 25 oz. In lbs, a standard hoodie weights 1.2 to 1.5 lbs.

Manufacturers make hoodies and sweatshirts of much heavier, fleecy material, which weighs 200-250 GSM for a summer weight, 250-300 GSM for an all-year weight, and 300-400 GSM for a heavy, snug winter fabric.

How Much Does A T-Shirt Weigh?

The weight of T-shirt fabric plays a significant role in determining the overall weight of the shirt, although other factors also play a role. Larger shirts will weigh more for the same fabric weight; so will long-sleeved shirts, in both cases because they use more material.

Pockets will also add to the weight of the shirt. Men’s shirts also typically weigh slightly more than lady’s shirts. The typical T-shirt weighs between 3 ounces (85 grams) and 7 ounces (200 grams).

When determining the thickness of a shirt, remember that GSM or ounces per square yard are an actual weight of the fabric, whereas if you get a weight quoted for the shirt as a whole, the size and style will determine whether it is lightweight or heavyweight shirt.

When ordering, try to get hold of information on the GSM of the shirts. If you can only get information on the total weight of the shirts, you will have to figure out yourself from the size and style of the shirt, whether it is lightweight or heavyweight or somewhere in between.

The following table gives the weights of shirts from some popular T-shirt manufacturers in various sizes:

When shipping shirts to customers, bear in mind that the packaging will also weigh, and depending on the printing method you have used, the image on the shirt may also have added slightly to the weight. Digital printing adds less weight than screen printing, which adds less than a heat transfer.

What are T-shirt Singles?

T-shirt singles refers to the thread count of a t-shirt’s fabric. Lower-quality t-shirts are generally measured by 18 to 21 singles, while higher quality t-shirts have 32 singles or more. A higher t-shirt singles count typically equates to a “premium” t-shirt, which is less likely to wear or fade after washes.

Conclusion

As you can see, there is a lot to T-shirt weight, and knowing the difference between a cheap and cheerful throwaway weight and a high-quality weight that will last for years will help you to deliver quality to your customers.

Understand how ounces per square yard or grams per square meter work, and you will have a good handle on T-shirt weight.

The best way to get the best idea of shirt weight is to order 1-2 shirts that are light, medium, and heavyweight. Feel them up close and personal, and decide which is best for your customers.
