A technical pack, also known as a spec sheet or style sheet, is a detailed sketch of a garment that includes all of the necessary information to communicate your design accurately to your pattern maker and/or manufacturer. A tech pack should be provided to your pattern maker BEFORE they begin working on a prototype and it should be given to your manufacturer BEFORE production begins. Creating an accurate and well-organized tech pack will save you time and money by ensuring that your patterns are created correctly and that your garments are made according to your specifications.

What is a Tech Pack?

A technical pack, also called a garment specs or style sheet, is a document used by apparel designers and manufacturers to communicate design ideas and specifications for garments. The tech pack should include all the information necessary for someone to understand the design of the garment and how it should be made. Tech packs are created for each season or style of clothing, and can be emailed or mailed to vendors, factories, or patternmakers. They can also be used internally by designers and merchandisers to keep track of styles and garments.

The Benefits of Creating Tech Packs

Creating tech packs for your clothing line has a number of benefits. Firstly, it helps to ensure that your garments are made to the highest possible standards. By providing clear and concise specifications to your suppliers, you can be confident that they will understand exactly what you are looking for.

Secondly, tech packs can save you a lot of time and money in the long run. By having all of the relevant information in one place, you can avoid having to make constant amendments and corrections to your orders. This will help to keep your production costs down and ensure that your garments are delivered on time.

Thirdly, tech packs can help you to build strong relationships with your suppliers. By providing them with everything they need to know up front, you will be able to develop a rapport and understanding that can last for years to come.

How to Create a Tech Pack

A tech pack is a document that contains all of the specifications and information needed to produce a garment. This includes the pattern, fabric, trims, and construction details. Creating a tech pack may seem daunting, but we’ll walk you through the process step by step.

Step One: Sketch Your Design

The first step in creating a tech pack is to sketch your design. This doesn’t have to be anything fancy, a simple sketch of the front, back, and side views of your garment will suffice. Be sure to include all details such as pockets, buttons, and zippers in your sketch. Once you have your sketch, you can begin creating your tech pack.

Step Two: Choose Your Materials

Now that you’ve gathered all of your measurements, it’s time to think about the materials you want to use for your clothing line. This can be a bit daunting, but we’re here to help. Here are a few things to keep in mind as you start selecting fabrics and materials for your tech pack.

The first thing you need to do is decide what kind of fabrics you want to use. Do you want natural fibers like cotton or linen? Or synthetic fibers like polyester or nylon? Each type of fabric has its own benefits and drawbacks, so it’s important to choose the right one for your clothing line.

Once you’ve decided on the type of fabrics you want to use, it’s time to start thinking about colors and patterns. Do you want solid colors or printed fabrics? What kind of colors do you want to use? And what kind of pattern would look best on your clothing line? These are all important questions to answer as you start creating your tech pack.

Last but not least, you need to think about the other materials you’ll need for your clothing line. This includes things like buttons, zippers, and trim. Again, it’s important to choose the right materials for your clothing line so that everything looks cohesive and put together.

If you take the time to choose the right materials for your clothing line, it will pay off in the long run. Your clothes will look better and last longer, and your customers will be happy with their purchase. So don’t skimp on this step—take the time to do it right!

Step Three: Create a Flat Sketch

The next step is to create a flat sketch, also called a technical sketch or working sketch, of the garment. This sketch will show all of the details of the garment, such as seams, darts, pleats, and button placement. It is important to be as accurate as possible when creating this sketch, as it will be used to create the patterns for the garment.

When creating a flat sketch, start by drawing a basic outline of the garment. Then, add in all of the details, such as seams, darts, pleats, and button placement. Be sure to label each element so that it is clear what it is and where it goes. Once you have all of the details added, scan or photograph your sketch and save it to your computer.

Step Four: Add Measurements and Construction Details

Now you will need to add measurements and construction details to your tech pack. This is critical information for your manufacturer, as they will need to know things like finished garment measurements, pattern pieces, and construction details in order to generate a quote and produce your garments.

To start, you will want to add basic measurements for each size that you are offering. These will most likely be body measurements, but could also include things like sleeve length or inseam length. Be sure to specify which measurement corresponds to which size. You can either create a table or list these out one by one.

In addition to basic body measurements, you will also want to add any pattern pieces that your garment will require. For example, if you are making a t-shirt you will need front and back neckline height and width measurements, as well as sleeve length measurements. If you are making pants, you will need inseam length measurements and waistband width measurements. Be sure to indicate on each pattern piece which size it corresponds to.

Finally, you will want to add any construction details that your manufacturer will need to know in order to produce your garments. This could include things like the type of hem you want on your pants or the number of buttons on your shirt. Again, be as specific as possible so that there is no confusion when it comes time to production.

Once you have added all of the necessary information, your tech pack should be complete! Be sure to review it carefully before sending it off to your manufacturer so that you can catch any mistakes or discrepancies.

Step Five: Create a Bill of Materials

After you’ve finalized your sketch, it’s time to create a Bill of Materials (BOM). A BOM is an itemized list of all the materials needed to construct your garment. This will include everything from fabric and notions to trims and hardware. Creating a BOM is an important step in the tech pack process because it help you understand the true cost of your garment. When creating your BOM, be sure to include the following information:

-Item description
-Fabric content
-Price per unit
-Yardage/quantity needed
-Name and contact information for vendor
Once you have all of this information, you can begin creating your tech pack!


Now that you understand the components of a tech pack, you can start putting together your own. If this is your first time creating a tech pack, we recommend starting with a simple design. You can always add more detail as you become more comfortable with the process.

When working on your tech pack, remember to keep the following in mind:
-A tech pack is a living document that should be updated as your design evolves.
-Keep your target audience in mind when creating your design.
-Your tech pack should be as detailed as possible to ensure accurate communication with your manufacturer.
