What Is a Tech Pack?

A tech pack (short for technical package) is a detailed document that explains how a garment should be made. It follows a detailed tech pack format, so everything is easy to read and consistent.

It includes everything clothing manufacturers require to produce a garment correctly, such as technical sketches, measurements, fabric details, trims, and construction notes.

A typical tech pack includes spec sheets, material details, and clear instructions that manufacturers understand without guesswork. This helps teams avoid confusion during sampling and production.

For fashion designers and product developers, tech packs keep production accurate and on track. A clear tech pack helps prevent delays, reduces errors, and makes sure the final product meets your quality standards.

Whether you build it in Adobe Illustrator, Excel, or a product lifecycle management (PLM) tool, a professional tech pack helps your team and suppliers work from the same information and produce consistent results.

Key Components of a Tech Pack

A solid professional clothing tech pack keeps everyone aligned. The goal is to include the right level of detail without overwhelming your team or factory. Keeping information consistent and clear helps everyone work from the same reference point.

A tech pack typically includes several key elements:

• Cover page – Basic info like the garment style name, date, season, and contact details for easy reference

• Technical sketches – Show the main design elements of your idea in a flat, front, and back view

• Specification sheet (spec sheet) – Lists all garment measurements by size, including tolerances and exact values needed for fit and quality control

• Bill of materials (BOM) – A full list of materials and trim, including fabric type, fabric weight, hardware, labels, and other components

• Construction details – Notes on how to put the clothing together, such as how to stitch, where to put seams, and how to finish

• Cost sheet – This helps you figure out how much something will cost to make by listing things like ingredients, labor, and other costs

• Packaging and labeling – Clear directions on how to fold, put barcodes on, hang tags, and pack the item for shipping

Each part, when done right, helps communicate better, cut down on mistakes during production, and deliver a consistent final product.

How to Create a Tech Pack Step by Step

Below is a step-by-step guide to creating a professional tech pack for your clothing designs, even if you’re just starting out.

Step #1: Create Clear Technical Sketches

Start with detailed technical drawings of the front and back views.

These are often called technical flats, and they show the garment without stylization or movement. Keep the lines clean, accurate, and labeled where needed. Maintain good image quality so every detail is easy to read.

Many experienced designers use Adobe Illustrator or AI-powered tools like Onbrand AI Design to create these sketches. The goal is to help the maker understand every part of the garment’s construction, right down to the stitch lines, seams, and panels.

Display the item of clothing from multiple angles when needed, and include zoomed-in views for construction details that need more information.

Step #2: Build the Specification Sheet

Aside from the sleeve length, the spec sheet has precise measurements for the chest, waist, inseam, and other points. Take real numbers from your sample or plan and use them.

Make sure that the measures are the same in the whole size range and include tolerances (acceptable variations) or allowed differences.

This section is essential for pattern makers and quality control planners. It helps the fit sample and future production runs match your sizing expectations.

Step #3: List All Materials in the BOM

The BOM outlines all raw materials used in the garment. Include the main fabric, fabric type, fiber content, fabric weight, color codes, trim details (buttons, zippers, labels), and their placement.

Be specific. Instead of writing “cotton,” write “100% organic cotton, 200 GSM, plain weave.” This makes sourcing easier for factories and helps maintain consistency in the finished product.

Clear information about the material helps make sure that the finished garment meets your original needs and stays the same during production.

This section also connects directly to your cost sheet and supports accurate budgeting.

Step #4: Define Construction and Assembly Details

This part explains how the garment is made. There should be tips for different types of stitching, such as flatlock, overlock, and double-needle, as well as steps for placing seams, making pockets, and finishing the project.

If you can, back up your directions with technical drawings or detailed callouts. Manufacturers need to understand every process required to complete the piece, especially when garments have multiple components or layers.

Clear construction notes help improve quality control and reduce errors during sampling.

Step #5: Add a Cost Sheet to Estimate Production Costs

Your cost sheet helps you calculate production costs by tracking all expenses involved in making the garment. Include fabric cost per meter, trims, labor, packaging, and overhead.

Even a rough estimate helps your team make decisions with accurate pricing in mind, including minimum order quantities (MOQ) and margin targets.

Being able to see costs also helps you have better communication with vendors.

Step #6: Outline Packaging and Labeling Requirements

Don’t skip the packaging section. Here, specify how to fold, bag, tag, and name each item of clothing.

Include barcodes, hang tags, care labels, or custom inserts. These details help protect your brand identity and prevent issues when the final product is shipped to retailers or customers.

This section is especially useful for quality control planners who check every delivery before it leaves the factory.

Step #7: Final Review and Version Control

Once your tech pack is complete, double-check everything. Look for missing information, features that do not match up, or sketches that are out of date. Clean formatting matters, as your manufacturer should be able to find details without guessing.

Save your document with clear file names (e.g., “Jacket_Style123_TechPack_v2”) and maintain version control. This creates a clear record of updates as your design evolves.

If you have PLM software, take advantage of real-time communication tools to make sure everyone on your team is on the same page with the design changes.

A complete, up-to-date tech pack reduces issues caused by incomplete specifications and helps keep the production process running smoothly.

Tools and Templates to Help You Create Tech Packs

Creating a professional tech pack doesn’t require a complicated setup, but the right tools can make a big difference in speed, accuracy, and collaboration.

While some teams start with spreadsheets or downloads, growing brands quickly outgrow these workarounds and need something more reliable.

Here’s how teams typically approach tech pack creation:

Adobe Illustrator

Still the standard for technical sketches and fashion flats.

Illustrator gives designers the control they need for detailed garment drawings and is often used to create visuals that get pulled into the tech pack.

Microsoft Excel or Google Sheets

Useful for early-stage brands managing a small number of styles. Teams often use these tools to build BOMs or specification sheets, but manual data entry still takes up a lot of time.

As product volume grows, it becomes harder to manage updates, share files, and track version changes.

PLM Platforms

Fashion PLM tools like Onbrand PLM replace static files with live, editable tech packs.

You can build tech packs using pre-set tech pack templates, upload sketches, manage spec sheets and materials, and track every update in one place.

Collaboration happens in real time, so your team and vendors stay aligned without digging through emails or re-exporting PDFs. If you’re just getting started, you may find free tech pack templates online to start creating your first version.

But for brands managing multiple styles or suppliers, a purpose-built system like Onbrand PLM helps teams work more cost-effectively by keeping everything connected and reducing rework.

What Not to Do When Creating a Tech Pack

Even a small error in a tech pack can lead to costly missteps during production. Whether you’re a new fashion designer or managing a growing brand, avoiding these common tech pack mistakes can save time, money, and materials.

• Missing or unclear measurements – Leaving out key sizing details or tolerances can result in poor fits. Always double-check your spec sheet for exact measurements, especially in high-impact areas like shoulders, waist, or inseams.

• Inconsistent or outdated files – If you’re not using version control, small updates can get lost. Keep one master file and make sure everyone’s working from the latest version to avoid confusion.

• Vague technical sketches – Sketches that lack clarity or detail can cause misinterpretation. Stick with professional flat sketches that show construction lines, seam placements, and any special features.

• Incomplete material or trim info – Missing fabric type, weight, or color codes makes it harder for manufacturers to source correctly. Always fill out your BOMs with specifics.

• Skipping packaging instructions – Overlooking folding or labeling requirements can hurt brand presentation and quality control. Add simple, clear packaging notes in your tech pack to guide final prep.

• Overcomplicating your first pack – Trying to include too much detail upfront can slow you down. Focus on the essentials first, then build in more as needed. This helps reduce the learning curve while keeping your process consistent.

Avoiding these mistakes helps create tech packs that are easier to follow, revise, and use for your entire team.
