Why Fabric Choice Matters More Than You Think
Most people shopping for a custom t-shirt focus almost entirely on the design — but the fabric underneath that design plays an equally important role. The material affects how comfortable the shirt feels, how the print looks and lasts, how the garment holds its shape over time, and even how much it costs to produce.
Here's what you need to know about the most common t-shirt fabrics.
100% Cotton
Cotton is the most widely used fabric in custom t-shirts, and for good reason. It's breathable, soft against the skin, and widely available at various price points.
Types of Cotton
- Combed cotton: Fibers are combed to remove impurities, resulting in a smoother, softer fabric with less pilling.
- Ring-spun cotton: Fibers are twisted during spinning, creating a finer, stronger yarn. Ring-spun tees feel noticeably softer than standard cotton.
- Combed ring-spun cotton: The best of both processes — the softest and most durable cotton option.
- Organic cotton: Grown without synthetic pesticides or fertilizers; appealing to eco-conscious buyers.
Pros & Cons
- ✅ Soft, breathable, and comfortable
- ✅ Best results with DTG printing and screen printing
- ✅ Easy to dye; vibrant colors
- ❌ Can shrink in the wash if not pre-shrunk
- ❌ Not ideal for sublimation printing
- ❌ May wrinkle more easily than synthetics
100% Polyester
Polyester is a synthetic fabric that's lightweight, moisture-wicking, and highly durable. It's the go-to choice for performance apparel, athletic wear, and sublimation printing.
Pros & Cons
- ✅ Excellent for sublimation (ink bonds chemically with polyester fibers)
- ✅ Moisture-wicking and quick-drying
- ✅ Holds shape well; minimal shrinking
- ✅ Lightweight and durable
- ❌ Less breathable than cotton; can feel warmer
- ❌ DTG printing is less effective on polyester
- ❌ Some people find the feel less comfortable against skin
Cotton-Polyester Blends
Blended fabrics combine the strengths of both fibers. The most common blends are 50/50 (cotton/polyester) and 60/40, though tri-blends (cotton, polyester, and rayon) have become popular in fashion-forward apparel.
Common Blend Ratios
| Blend | Feel | Best Use |
|---|---|---|
| 50/50 Cotton-Poly | Smooth, slightly synthetic | Budget-friendly merch, workwear |
| 60/40 Cotton-Poly | Softer, more cotton-like | Everyday wear, custom tees |
| Tri-blend (CRP) | Very soft, lightweight, drapes well | Fashion tees, premium merch |
Pros & Cons
- ✅ Less shrinkage than 100% cotton
- ✅ Good balance of breathability and durability
- ✅ More affordable than premium pure cotton
- ❌ DTG colors may appear slightly less vibrant than on 100% cotton
- ❌ Sublimation doesn't work well on high-cotton blends
Fabric Weight: What the GSM Number Means
T-shirt weight is measured in GSM (grams per square meter). This is one of the most useful specs when choosing a blank garment:
- Under 150 GSM: Very lightweight; great for summer or athletic wear, but may feel thin or see-through.
- 150–180 GSM: Standard weight for most everyday t-shirts. Good balance of comfort and durability.
- 180–220 GSM: Mid-weight; feels substantial and premium. Popular for fashion and brand apparel.
- 220+ GSM: Heavyweight; structured and durable. Common in workwear and specialty garments.
How Fabric Affects Print Quality
Your choice of fabric directly impacts how well a print looks and lasts:
- DTG printing: Works best on 100% cotton with a tight weave. High polyester content can cause color dullness.
- Screen printing: Works well on cotton and most blends. Highly textured fabrics can make fine details harder to print cleanly.
- Sublimation: Requires 100% polyester (or high-poly blends). Won't bond properly with cotton fibers.
- Heat transfer vinyl: Works on virtually any fabric, making it versatile for mixed-fabric garments.
