What is a Tech Pack?

A tech pack is a document that contains all of the information necessary to develop a garment. This document typically includes sketches, measurements, fabric requirements, and other technical details.

A technical or “tech” pack is a document containing all of the specifications and construction details for a garment. It is used by factories to price out a style and by pattern makers to generate patterns. A tech pack should include the following:

-A sketch or illustration of the garment
-A detailed description of the garment including measurements, fabric, trim, etc.
-A flat sketch of the garment showing all measurements and details
-Construction details such as seam type, stitching, button placement, etc.
-A size chart
-Instructions for care label

What is a tech pack?

A technical pack, also called a tech pack or spec sheet, is a document used by clothing manufacturers and designers to clearly communicate design specifications and construction details for garment production. A tech pack typically includes CAD drawings with detailed measurements, colorways and fabrications, garment construction details, bill of materials, etc.

A well-designed tech pack will help ensure that your garments are constructed according to your specifications, minimizing potential production issues and errors. In addition, a tech pack can be used as a sales tool to help secure orders from buyers or investors.

The benefits of a tech pack

A tech pack, also called a technical pack, is a document that outlines the specifications and construction details of a garments or accessory. Tech packs are used by apparel manufacturers and designers as a guide throughout the production process. From researching and sourcing fabrics to communicating design details to patternmakers and sewers, tech packs are an essential tool in bringing fashion products to life.

A well-crafted tech pack should be clear and concise, providing all the information necessary for someone to understand and recreate your design. A tech pack should include sketches or technical drawings of the garments, as well as detailed descriptions of the materials, construction methods, measurements, and any other special instructions.

While a lot of information can be conveyed verbally, having everything spelled out in a tech pack helps to ensure that everyone involved in the manufacturing process is on the same page. This reduces confusion and provides a reference point should any questions arise. Having a Tech Pack also allows you to more easily compare quotes from different manufacturers.

In short, a Tech Pack saves time and money by reducing mistakes and miscommunication throughout the garment production process.

How to create a tech pack

Creating a technical package can seem daunting, but it doesn’t have to be. A technical package is simply a set of instructions that a manufacturer uses to produce your product. It is a crucial step in the product development process, as it ensures that your product is made to your specifications and meets all quality and safety standards.

There are three main elements to a tech pack:

1. The Product Specification: This includes all the detailed information about your product, such as dimensions, materials, colors, etc.

2. The Technical Drawing: This is a detailed illustration of your product that shows all its features and construction details.

3. The Bill of Materials: This is a list of all the materials and components that are required to make your product.

The different types of tech packs

A technical specification (tech pack) is a document used by a garment manufacturer or fashion designer to detail all of the information necessary to produce a given style of garment. This includes instructions on how the garment should be constructed, a bill of materials specifying all fabrics and trims needed to make the garment, as well as measurements and product codes for ordering purposes. A good tech pack will also include flat sketches or illustrations of each view of the garment as well as photos or swatches of any special details such as appliques, embroideries, etc.

There are three main types of tech packs:

1. Master Spec Sheets: These are used by designers to keep track of all the details for a given style (or set of styles) throughout the design process. They typically include all information that would eventually be included in a production tech pack, but in a more condensed format.

2. Production Tech Packs: These are used by manufacturers to actually produce garments. They should be very specific and include all information necessary for construction, such as measurements, fabric & trim requirements, etc.

3. Salesman Samples: These are versions of production tech packs that are created before actual production begins. They are typically used for sales meetings or trade shows in order to give buyers a better idea of what the final product will look like.


A technical pack, also called a spec sheet, is a document that contains detailed instructions on how to manufacture a garment. The specs will include information on the materials needed, the construction methods to be used, the measurements of the finished product, and any other instructions that will ensure the garment is made correctly.

A well-made technical pack will help streamline production and avoid errors by providing clear and concise instructions to all involved in the manufacturing process. This includes pattern-makers, cutters, sewers, and Trim & Finish specialists. In some cases, a sample garment may be included with the tech pack as a reference.

While tech packs can vary greatly in terms of content and format, most will include the following sections:

-Description: A brief overview of the garment, including its intended use and any special features or details.

-Materials & Trims: A list of all materials and trims required to make the garment, along with any specific requirements (e.g., type of fabric, width of trim).

-Construction: Step-by-step instructions on how to assemble the garment, from cutting out the pieces to attaching trims and labels. This section will also call out any special construction techniques that need to be used.

-Finishing: Instructions on how to finish the garment, including any pressing or steaming that needs to be done.

-Measurements: A list of all measurements for the finished garment, both flat (laying down) and on the body (bust/waist/hip).
