Fabric, GSM, Sizing, Labels, Printing, Packaging & Bulk Manufacturing
A Complete Guide to Building Your Custom T-Shirt with Modazer
Creating a professional custom T-shirt involves much more than choosing a color and adding a logo. For businesses, clothing brands, corporates, schools, events and organizations, every detail matters—from the fabric and GSM to sizing, labels, printing and packaging.
At Modazer, we provide a complete T-shirt manufacturing and customization solution, helping customers bring their apparel requirements from an initial idea to a finished product.
1. Fabric — The Foundation of Your T-Shirt
The fabric you choose influences the T-shirt’s comfort, appearance, weight, durability and overall feel.
Depending on the intended application, Modazer can help you select suitable fabric options such as:
100% Cotton
A popular option for everyday T-shirts, promotional apparel and casual wear.
Key characteristics:
- Comfortable feel
- Good breathability
- Suitable for everyday use
- Available in different weights
Polyester
Commonly used for sportswear and performance-oriented applications.
Key characteristics:
- Lightweight options available
- Quick drying
- Durable
- Suitable for many sportswear applications
Cotton-Polyester Blends
A blend combines cotton and polyester characteristics.
Key characteristics:
- Balance of comfort and durability
- Suitable for regular-use apparel
- Useful for many uniforms and promotional T-shirts
The right fabric depends on your purpose, budget, printing requirements and desired finish.
2. GSM — Choosing the Right Fabric Weight
GSM means Grams per Square Meter.
It is commonly used to describe the weight of the fabric.
Generally:
Lower GSM = Lighter Fabric
Higher GSM = Heavier Fabric
Some commonly requested ranges include:
| GSM | General Character | Possible Applications |
| 140–160 GSM | Lightweight | Promotional & summer T-shirts |
| 160–180 GSM | Medium-light | Corporate & event T-shirts |
| 180–200 GSM | Medium/heavier | Premium promotional & regular wear |
| 200–240+ GSM | Heavyweight | Oversized & premium T-shirts |
GSM alone does not determine fabric quality. Fiber composition, yarn, knitting construction and finishing also influence the final garment.
Modazer can help you select an appropriate GSM according to the climate, style, application and budget.
3. Sizing — Getting the Right Fit
A well-designed T-shirt should have consistent measurements across the production order.
Modazer can manufacture different size ranges according to the requirement.
Typical adult sizes include:
S | M | L | XL | XXL | 3XL
Depending on the product, larger or smaller sizes can also be planned.
Size planning is particularly important for:
- Employee uniforms
- School and college orders
- Sports teams
- Events
- Corporate campaigns
- Retail apparel
For bulk orders, we recommend confirming the size chart and size-wise quantity before production.
4. Labels — Build Your Brand Into the Garment
Labels are an important part of professional apparel.
Depending on the requirement, customized garments can include:
Neck Labels
Used to display:
- Brand name
- Logo
- Size
- Product information
Size Labels
Useful for quickly identifying sizes such as:
S | M | L | XL | XXL
Care & Composition Labels
Can provide information such as:
- Fabric composition
- Washing instructions
- Care instructions
- Manufacturer details
Custom Branding
For clothing brands, customized labels help create a consistent brand identity across the product range.
Modazer can help incorporate labeling requirements into your manufacturing specification.
5. Printing — Give Your T-Shirt Its Identity
Printing is where your design becomes part of the garment.
Depending on the fabric, design and quantity, different printing methods can be considered.
Screen Printing
Suitable for many bulk orders, particularly logos and designs with relatively limited colors.
DTF Printing
Suitable for detailed, colorful and multicolor artwork.
Heat Transfer
Useful for certain customized designs, names, numbers and short-run requirements.
Sublimation
Suitable for appropriate polyester garments, particularly many sportswear applications.
The printing method should be selected according to:
Design + Fabric + Quantity + Application + Required Finish
6. Packaging — The Final Presentation
Packaging protects the garment and also contributes to the customer’s first impression.
Depending on the requirement, Modazer can organize packaging according to the type of order.
Possible options include:
- Individual T-shirt packing
- Size-wise packing
- Color-wise packing
- Design-wise packing
- Bulk carton packing
For retail and private-label orders, packaging can be planned as part of the overall product presentation.
7. Bulk Manufacturing — Turning Specifications Into Products
Once all specifications are finalized, the manufacturing process begins.
The general process includes:
Fabric → Pattern → Cutting → Stitching → Finishing → Labels → Printing → Quality Check → Packing
For bulk orders, production planning is important to maintain consistency across the complete order.
Key specifications can include:
- Fabric composition
- GSM
- Color
- Size
- Fit
- Stitching
- Label
- Packaging
The more clearly these specifications are defined before production, the easier it is to maintain consistency.
8. Sample Approval Before Bulk Production
For customized business or brand orders, a sample can be used to confirm the specifications before full-scale production.
The sample can be checked for:
Garment
- Fabric
- GSM
- Color
- Fit
- Measurements
Branding
- Label
- Logo
- Print size
- Print position
- Artwork
Finishing
- Stitching
- Threads
- Overall appearance
After the required specifications are approved, bulk manufacturing can proceed.
9. Quality Control
Quality control is an important part of bulk apparel manufacturing.
At Modazer, the finished products can be checked for:
Fabric → Measurements → Stitching → Color → Labels → Printing → Finishing → Packaging
The objective is to identify production issues before the order is packed and dispatched.
