Best Fabric for T-Shirts: Cotton Jersey, Jersey, or Interlock Knit
The t-shirt is the most universal garment in any wardrobe — and the backbone of most small-batch and made-to-order production. Three knit fabrics cover the vast majority of t-shirt applications: single jersey (the lightest), jersey (mid-weight), and interlock knit (double-faced). Each has its own weight range, end use, price point, and wash performance. The key decision factors are GSM, fiber content, and knit construction. Whether you're producing for an e-commerce platform or building your own brand, the requirements differ. Here's a full breakdown.
What Gets Made from T-Shirt Knit Fabrics
The t-shirt fabric category covers a wider range of garment types than most people expect. Each end use calls for a specific GSM range and fiber blend.
Lightweight summer t-shirts for hot weather and beach. Single jersey at 130–160 GSM, 100% cotton, no spandex (elastane). Breathable and non-restrictive. May show through in light colors when held to the light.
Year-round basic t-shirts. Single jersey at 160–180 GSM in a 95/5 cotton-spandex blend, or jersey at 180–200 GSM in the same blend. These hold their shape through a season of regular wear and take print well.
Fitted long-sleeve tops and structured t-shirts. Jersey at 200–230 GSM with 4–6% spandex (elastane). Contours the body without pulling or distorting, and is fully opaque in all colors.
Turtlenecks and mock-neck base layers. Interlock knit at 200–240 GSM, either 100% cotton or 95/5 with spandex. The double-faced structure sits cleanly at the neckline and looks polished at the stand collar.
Athletic t-shirts and running tops. Jersey with 6–8% spandex in a 90–94% polyester base, 160–200 GSM. Often finished with moisture-wicking treatments such as Coolmax.
Children's t-shirts and baby bodysuits. Single jersey at 140–170 GSM in 100% combed cotton or compact combed cotton. Hypoallergenic, soft surface, no pilling.
Corporate merch and branded merchandise for print. Single jersey or jersey at 160–180 GSM in 100% cotton or an 80/20 cotton-polyester blend. The smooth, even surface holds a sharp print through repeated washing.
Tanks, undershirts, and base-layer vests. Single jersey at 130–160 GSM, 100% cotton. Hypoallergenic and appropriate for direct skin contact.
Knit Types for T-Shirt Production
Three main constructions, each with a distinct structure and weight range.
Single jersey (cotton jersey). The lightest of the three, typically 130–180 GSM, with a smooth face and a visible loop back. Lightweight, breathable, and soft against the skin. The practical upper limit is around 200 GSM — above that, the fabric is generally classified as jersey.
Jersey. A weft-knit fabric ranging from 130–280 GSM with a smooth face. Heavier than single jersey, usually blended with spandex. The go-to base fabric for t-shirts, long-sleeve tops, and dresses.
Interlock knit. A double-knit fabric at 200–240 GSM with an identical smooth face on both sides. Less stretchy than jersey, with better shape retention. Best suited to turtlenecks, mock necks, and clean office-casual styles.
For a full comparison of all knit constructions, see the guide "Knit Fabrics: How to Choose" and the GSM breakdowns in "Single Jersey GSM Guide" and "Jersey GSM Guide".

Choosing the Right GSM for Your Garment
GSM selection depends on the garment type and your end customer.
130–150 GSM (lightweight single jersey). Summer t-shirts, nightshirts, baby bodysuits (0–3 months), and undershirts. Shows through on white — works well in dark colors. 100% cotton, no spandex.
160–180 GSM (mid-weight single jersey or light jersey). The standard GSM for a year-round basic t-shirt. Fully opaque, holds shape, takes printed graphics well. Use a 95/5 cotton-spandex blend for resistance to stretch-out at the elbows and chest.
180–200 GSM (standard jersey). A solid everyday t-shirt or base-layer long-sleeve. Fully opaque across all colors. 95/5 blend with 4–6% spandex is the most common spec.
200–220 GSM (heavyweight jersey or interlock). Fitted t-shirts, structured long-sleeve tops, turtlenecks. Spandex content 5–8%.
220–240 GSM (dense interlock). Warm long-sleeve tops, stand-collar turtlenecks, polished office-casual styles. Double-faced construction.
Fiber Content: What to Look For
Fiber blend determines how a t-shirt performs after 20–50 washes.
Cotton 80–100%. The foundation of any quality t-shirt. Higher cotton content means a softer hand and better breathability, but the garment may stretch out faster without polyester stabilization. Use 100% cotton for childrenswear and premium capsule collections. Use an 80/20 cotton-polyester blend for branded merchandise and mass-market production.
Spandex (elastane) 3–8%. Optional, but recommended for fitted styles. 3–5% for basic t-shirts to prevent bagging at elbows and cuffs; 5–8% for fitted long-sleeve tops and athletic styles.
Polyester 15–30%. Reduces fabric cost and improves durability. Common in branded merch and mass-market production as an 80/20 or 65/35 cotton-polyester blend. The trade-off: reduced breathability — in warm conditions, a high-polyester fabric will feel synthetic against the skin.
What to avoid. Rayon (viscose) above 10% in the blend — it sags and distorts after washing. "Synthetic" fiber content with no specified type — this usually signals a low-grade polyester that pills within 5–10 washes.
For a full breakdown of spinning technologies — open-end cotton (rotor-spun), carded cotton, combed cotton, and compact combed cotton — see the guide "OE, Carded, Combed, or Compact Combed Cotton." For mass-market merch, carded is the standard; for premium production, use combed or compact combed cotton.
How Much Fabric Do You Need per T-Shirt
Standard roll width for single jersey and jersey is 165–185 cm (65–73 in). Fabric consumption varies significantly with production scale.
Individual / one-off cutting:
Production run of 10–50 units in one style (nested industrial marker):
Production runs of 100+ units: yardage drops a further 5–10% when multi-size nesting is used in the cutting layout.
Cuffs, neckbands, and binding strips are cut from 1x1 rib knit at 170–220 GSM or a finer 2x2 rib knit at 250–280 GSM. Allow approximately 0.1–0.15 m of rib per t-shirt. For rib knit selection, see the guide "2x2 Rib vs 1x1 Rib."
Wastage allowance: add 15% for one-off cutting, 5–10% for production runs. Always cut knit fabrics on the grainline.
Pricing: Wholesale vs. Retail
Retail fabric pricing (by the yard, online) is typically two to three times higher than wholesale. As a general guide:
Single jersey 100% cotton at 140–180 GSM sits at the accessible end of retail pricing. Jersey at 180–200 GSM with spandex falls into a mid-range retail bracket. Heavyweight jersey and spandex blends at 200–240 GSM, along with interlock, are priced at the mid-to-upper end of the retail range.
At wholesale, the price ladder follows spinning quality: open-end cotton (rotor-spun) is the most affordable, followed by carded cotton, combed cotton, and compact combed cotton at the premium end — typically 50–80% more per meter than the open-end equivalent at the same GSM.
For a small production run of 10 basic t-shirts (7–9 m of fabric), wholesale fabric cost is a fraction of the retail selling price. A well-spec'd fabric — combed or compact combed cotton at the right GSM — meaningfully improves perceived quality and repeat purchase rates, which matters more for a direct brand than for marketplace volume selling.
For marketplace and e-commerce platform production, an 80/20 carded cotton-polyester blend is the standard cost-efficient spec. For a direct brand, 100% combed or compact combed cotton typically commands a 30–50% price premium at retail and builds stronger customer loyalty.
Recommended Fabrics by Garment Type

Common Mistakes When Choosing T-Shirt Fabric
A few recurring errors worth knowing before you cut.
Using 140 GSM single jersey for a long-sleeve top. Lightweight single jersey bags out at the elbows within a month of regular wear. For long-sleeve tops, use 170–190 GSM with spandex, or jersey at 180–200 GSM.
Cutting a fitted t-shirt from fabric without spandex. Cotton jersey will stretch, but the recovery is slow. After three or four wears, the garment sags at the chest and underarms. For fitted styles, use a 95/5 or 92/8 cotton-spandex blend.
Using 130 GSM fabric for white or pale t-shirts. At this weight, underwear shows through in light colors. For white and light-colored styles, use a minimum of 170 GSM.
Using budget open-end (rotor-spun) cotton for a premium capsule collection. Open-end yarn has a slightly hairy surface. After 10–15 washes, the fabric pills at friction points — underarms, side seams. For premium production, use combed cotton as a minimum.
Skipping pre-shrinking before cutting. 100% cotton single jersey shrinks 3–5% on the first wash. Always pre-wash your fabric at 40–60°C before cutting the pattern.
Mismatching the fiber content of the body and trims. If the body fabric is a cotton-spandex blend but the rib knit trim is 100% cotton, they will shrink at different rates in the wash — the cuffs will ripple and distort. Use rib knit trim with the same fiber blend as the body fabric.
Ordering exactly to the calculated yardage with no buffer. Always add 5–10% for production runs to cover defects, roll ends, and cutting waste. For one-off cutting, add 15%.
Frequently Asked Questions
What is the best fabric for t-shirts that hold their shape? Single jersey at 160–180 GSM in a 95/5 cotton-spandex blend, or jersey at 180 GSM in the same blend. Both resist stretch-out, maintain their shape through 30 washes, and take screen print and DTG print well. This is the standard spec for a quality year-round basic.
What is the difference between single jersey and jersey? Single jersey runs 130–180 GSM with a fine, smooth face. Jersey is heavier — 180–240 GSM — and more commonly blended with spandex. The practical boundary sits around 200 GSM, and the same fabric may be described differently by different suppliers.
What is the best t-shirt fabric for children's clothing? Single jersey at 140–170 GSM in 100% combed cotton or compact combed cotton. Hypoallergenic, smooth surface, resistant to pilling. For children's long-sleeve tops, use 170–200 GSM 100% cotton with 3–5% spandex.
What fabric works best for printed t-shirts and branded merchandise? Jersey at 180 GSM in 100% cotton or an 80/20 carded cotton-polyester blend. The smooth, consistent surface delivers sharp print registration and holds it through 30+ washes without cracking. For premium merch, specify jersey at 180 GSM in compact combed cotton.
Can you use interlock knit for t-shirts? Yes — especially for fitted styles with a stand collar or mock neck. Interlock at 200–220 GSM with spandex gives a clean silhouette and is easy to finish neatly. For standard basic t-shirts, single jersey or jersey is the more common and more cost-efficient choice.
How much fabric do I need per t-shirt? Standard adult t-shirt: 0.9–1.1 m for one-off cutting, 0.7–0.9 m per unit in a production run. Children's t-shirt (ages 5–10): 0.6–0.8 m one-off, 0.45–0.55 m in a run. Fitted t-shirt: 0.65–0.8 m per unit in a production run.
What is the best material for t-shirts sold through e-commerce marketplaces? An 80/20 carded cotton-polyester blend at 160–180 GSM. Good price-to-durability ratio, holds print well, available in a full color range including the core basics — black, white, grey, navy, burgundy. Not a premium hand feel, but a proven performer for high-volume print-on-demand and marketplace selling.
What fabric do established brands use compared to marketplace sellers? Marketplace and e-commerce volume sellers typically use an 80/20 carded blend — the best balance of cost and wash durability at scale. Direct brands typically specify 100% combed or compact combed cotton. The tactile difference is immediately noticeable; the fabric looks better for longer and commands a 30–50% higher retail price. See the guide "Fabric Specs for Marketplace Sellers vs. Direct Brands" for a full comparison.
Where do I source t-shirt fabric at wholesale? Look for wholesale textile suppliers with imported knit fabric ranges, or source directly from Turkish and Uzbek mills for premium-quality fabric. Minimum order quantities are typically one full roll — usually 50–80 m per colorway.
