A tech pack (technical package) is your design's blueprint for production—the detailed instructions that tell a manufacturer exactly how to make your garment. Without one, you're essentially asking a factory to guess your vision, which leads to expensive sample revisions and production errors. This guide covers everything you need to create professional tech packs.
📐 Key Takeaways
- Tech packs prevent miscommunication and reduce sample revisions
- Essential components: flats, measurements, BOM, construction notes
- Cost: $50-500 per style, or included with some manufacturers
- Time to create: 2-8 hours per style
- Every unique style needs its own tech pack
What Does a Tech Pack Include?
A complete tech pack contains these essential elements:
1. Technical Flat Drawings
Front and back views of your garment in a simplified, technical style. Flats show construction details, seam placements, and design features without distraction from colors or patterns.
2. Measurement Specification Sheet
A detailed chart listing every measurement point (POM - Point of Measure) for all sizes in your range. Includes tolerances (acceptable variation, typically ±0.25-0.5").
| Point of Measure | S | M | L | XL | Tolerance |
|---|---|---|---|---|---|
| Chest (1" below armhole) | 20" | 22" | 24" | 26" | ±0.5" |
| Body Length (HPS to hem) | 27" | 28" | 29" | 30" | ±0.5" |
| Sleeve Length | 8" | 8.5" | 9" | 9.5" | ±0.25" |
| Neck Width | 7" | 7.5" | 8" | 8.5" | ±0.25" |
3. Bill of Materials (BOM)
A complete list of every material used in production:
- Shell fabric: Main body material, weight, composition
- Lining: If applicable
- Trims: Buttons, zippers, snaps, drawcords
- Thread: Color and weight specifications
- Labels: Brand label, care label, size label
- Packaging: Hang tags, poly bags
4. Colorways
All color variations with Pantone references or fabric swatches. Specify placement for multi-color designs.
5. Construction Details
Annotations explaining how the garment should be constructed:
- Stitch types (single needle, double needle, overlock)
- Seam allowances
- Hem finishes
- Reinforcement points
- Special treatments (enzyme wash, garment dye)
6. Artwork & Graphics
Prints, embroidery, or embellishment specifications with exact placements and dimensions.

Why Tech Packs Matter
Skip the tech pack and you're gambling with your production budget:
Without a Tech Pack
- 3-5+ sample revisions average
- $100-300 wasted per revision
- 2-4 weeks delay per revision cycle
- Production errors in bulk orders
With a Proper Tech Pack
- 1-2 sample revisions typical
- Faster production start
- Consistent quality across batches
- Clear reference for quality control

1. Missing Measurement Details
Problem: Vague measurements like "regular fit"
Solution: Every dimension needs a number and tolerance
2. Incomplete BOM
Problem: Forgetting trims, labels, or thread specifications
Solution: List every single component, even small items
3. Unrealistic Tolerances
Problem: Expecting ±0.1" precision on cut-and-sew garments
Solution: Industry standard is ±0.25-0.5" depending on measurement
4. Poor Communication of Design Intent
Problem: Assuming the factory understands your vision
Solution: Add notes explaining "why" for unusual features
5. Ignoring Grading Rules
Problem: Measurements that don't grade proportionally
Solution: Follow standard grade rules or hire a grader

When to Hire a Technical Designer
Consider professional help if:
- You're creating 10+ styles per season
- Designs include complex construction (outerwear, tailoring)
- You lack experience with grading
- Previous production had quality issues
- You're targeting premium or luxury markets
Freelance technical designers charge $30-80/hour, or you can work with manufacturers who include this service.
Frequently Asked Questions
What is a tech pack in clothing manufacturing?
A tech pack (technical package) is a detailed blueprint that communicates your design specifications to a manufacturer. It includes technical flats, measurements, materials, construction details, and colorways. Without a tech pack, manufacturers must guess your intentions, leading to costly sample revisions and production errors.
How much does a tech pack cost?
Tech pack costs range from $50-500 per style depending on complexity. Simple t-shirts may cost $50-100, while complex garments like jackets with multiple components cost $200-500. Some manufacturers, including Sanchuan Apparel, provide tech pack assistance as part of their development services at reduced or no additional cost for production clients.
What software is used to create tech packs?
Common tech pack software includes Adobe Illustrator (industry standard), CLO3D (3D design), Techpacker (cloud-based), and Optitex. For simple projects, some designers use Canva or even Excel spreadsheets. The key is clear communication—software choice matters less than accurate specifications and detailed annotations.
How long does it take to create a tech pack?
Creating a tech pack takes 2-8 hours per style depending on complexity. Simple t-shirts may take 2-3 hours, while complex activewear or outerwear can take 6-8 hours. Experienced technical designers work faster. If you're new to tech packs, expect to spend additional time on revisions and learning measurement standards.
Do I need a tech pack for every style?
Yes, you need a tech pack for every unique style. Even similar styles with different features (e.g., long sleeve vs short sleeve) require separate tech packs. However, you can use a base template for related styles to save time. Sanchuan Apparel requires tech packs for all production orders to ensure quality and accuracy.
