Most buyers don't think about tee weight until they hold a finished sample and decide they don't like how it feels. By then the order's been placed, the print's been done, and the fix is "next time, ask about weight."

This is that conversation, before the order goes in.

Tee weight is measured in grams per square metre (gsm) or ounces per square yard (oz). The conversion is messy — 1 oz/yd² is roughly 33.9 gsm — but the categories are stable. Lightweight tees sit around 130–160 gsm. Midweight is 170–200 gsm. Heavyweight starts at 200 gsm and runs up to about 240 gsm. Anything beyond that is in "maxweight" territory and behaves differently again.

Each band exists for a reason. The mistake is assuming heavier means better. It doesn't — it means different.

Lightweight (130–160 gsm)

Lightweight tees are what most people picture when they think "fashion tee" — thin, drapey, slightly translucent against light, soft to the hand. They photograph well, they cut for silhouette rather than coverage, they layer under jackets and overshirts without bulk.

The economics of lightweight: less fabric per shirt means lower cost per unit and lower freight cost per piece. For event giveaways where the audience won't put the tee through 50 wash cycles, lightweight makes sense. For fashion-focused retail drops where the look matters more than the durability, lightweight is the right tier. For summer staff tees in client-facing roles where breathability matters, lightweight handles heat better than anything else.

What lightweight isn't good for: anything that needs to last. Lightweight tees thin out faster, pill earlier under abrasion, and lose their shape with repeated washing. They print fine — DTG and screen print both handle them — but heavy embroidery looks wrong on lightweight fabric, pulling and puckering around the design.

The honest version of lightweight is that it works when the use case is short-term, fashion-focused, or hot weather. It stops working the moment "uniform" enters the conversation.

Midweight (170–200 gsm)

This is the standard. The default. The tee weight that ninety percent of corporate and event apparel orders should be specifying, even if no-one says it out loud. The Gildan Softstyle 64000 sits at 153 gsm — close to lightweight, but the dense ring-spun knit puts it at the bottom of midweight territory in feel. The Gildan Heavy Cotton 5000 lands at 180 gsm — squarely midweight. Most of the global tee market sits in this band because midweight handles every common use case acceptably.

What midweight does: prints cleanly with all common methods, holds embroidery without distortion, washes 30+ times without dramatic change, photographs neutrally (not too sheer, not too boxy), wears comfortably across temperature ranges, and ships at a reasonable freight cost.

What it doesn't do: stand out. Midweight is the right answer when "tee that does its job" is the brief, which is most jobs. It's the wrong answer when the brief specifies a feel that customers should notice — premium drops, hospitality uniforms with a certain weight in the hand, retail merch positioned above $40.

For staff uniforms across office environments, midweight is almost always the right call. For brewery tees, retail-bound merch, and brand drops, it depends entirely on positioning. A midweight tee in a retail context can read as "merch" instead of "product" — which is fine if the price reflects it, and a problem if the price doesn't.

Heavyweight (200–240 gsm)

Heavyweight tees are the streetwear silhouette. The Comfort Colors 1717 at 207 gsm. The American Apparel 1301 at 217 gsm. The category that holds shape, feels substantial in the hand, and carries print weight without distortion.

What heavyweight signals: this is a real piece of apparel, not a throwaway. Customers can feel the difference at first touch — the fabric has body, the seams sit where they're stitched, the silhouette doesn't collapse with wear. For retail drops, premium merch, music apparel, and anything where the price tag is north of $40, heavyweight justifies what you're charging.

What heavyweight is not good for: hot weather, cardio activities, layering pieces, or any context where the wearer needs to move comfortably for hours. Heavyweight cotton holds heat and absorbs sweat without drying quickly. For festival merch — where customers wear it in 30°C+ sun — heavyweight cotton can be the wrong call even though it photographs better.

The other thing about heavyweight: shipping cost. Doubling the weight of the tee adds meaningfully to freight when you're sending 200+ pieces interstate. For online drops fulfilling individual orders, heavyweight adds maybe a dollar to each shipment. For wholesale runs to distributors, it can shift the freight calculation enough to matter.

Maxweight (240+ gsm)

This is the territory of the Gildan Hammer 75000 at 237 gsm, and the new generation of streetwear-positioned heavy tees built specifically for retail drops where weight is the marketing story. Boxy oversized cuts. Drop shoulders. Dense ring-spun cotton with a hand-feel that registers as "expensive" before the customer reads the price tag.

Maxweight tees work for one thing: positioning. If the brief is a retail drop priced at $55+, a maxweight tee photographs differently and feels differently in a way that justifies the spend. The Hammer Maxweight collection was built explicitly for this — boxy, drop-shoulder, recycled tear-away label, designed to slot into the streetwear aesthetic that consumers learned to want from brands like Fear of God and Cole Buxton.

What maxweight stops being right for: anything that's not a retail drop. As corporate uniform, maxweight reads as overdesigned. As event giveaway, it's massively over-spec. As warm-weather staff apparel, it's actively uncomfortable. As kids' apparel, it's wrong-cut entirely.

The maxweight category has a clean use case: brand-led retail. Outside that, you're paying for a feel the customer won't notice in a context where the weight isn't a feature.

Choosing the right weight for the brief

For corporate giveaways under $15 a head: lightweight or low-end midweight. Cost per piece dominates.

For staff uniforms across an office environment: midweight, no debate. Specifically the 170–185 gsm band — heavy enough to last, light enough to wear comfortably year-round.

For brewery, hospitality, and venue uniforms where staff are moving in heat: lightweight if poly-blend; midweight if 100% cotton. The fabric matters more than the weight here.

For retail drops: depends entirely on the price point. Under $40, midweight. $40–55, heavyweight. $55+, maxweight if the brand identity supports it.

For event merch and conference giveaways: midweight is almost always right. Lightweight feels cheap in the hand at the moment of giving; maxweight feels overengineered.

For sports teams and performance apparel: tee weight isn't the right framing — fabric composition matters more. A 150 gsm performance polyester behaves nothing like a 150 gsm cotton.

Where heavier stops being better

The trap with tee weight is that it's a metric customers can hold in their hand and judge instantly, which makes it tempting to reach for heavier as the "premium" answer. It's not. Three places where heavier is wrong.

The first: warm-weather staff uniforms. Heavyweight cotton in a 30°C kitchen, café, or warehouse is genuinely uncomfortable for the people wearing it. The right answer for hot environments is midweight in a poly-cotton blend, or lightweight in performance polyester — not heavyweight because it "feels nicer at handover."

The second: kids' apparel. Children's tees should be lighter than adults', not just smaller. A heavyweight cotton tee on a six-year-old reads as armour, not clothing. Most childrenswear sits at the lighter end of midweight by default for a reason.

The third: minimal or feminine cuts. Heavyweight tees are built around boxy, structural silhouettes. A heavyweight tee in a women's fitted cut fights itself — the fabric wants to be boxy, the cut wants to be tailored, and the result is a garment that doesn't move well. Heavyweight wants drop-shoulder boxy fits to make sense.

The right tee weight is the one that suits the use case. The wrong tee weight is the one your printer recommended without asking what the apparel was for. Match the weight to the job.
