What are the key elements and details to include in a tech pack for different product categories?

In addition to the above I like to add a small section with the date created & initials of the creator. (ex: 4.24.23 JP) This avoids confusion making it easy to identify the latest version and who to approach with questions/ clarifications. Each time an update is made add the new Revision date in a different color with brief comments to what was updated. Point out those changes in the same color so it's very clear as to what is changing. (ex: REV. 4.26.23 JP updated labels, thread color, sketch) Keep the original date in black so you can see when it was created. Use RED font for any callouts you want to stand out on initial tech pack, and then a lighter BLUE/TEAL, etc for Revision callouts to avoid confusion. You can also highlight changes.

The key elements that all product categories share in the tech pack are mostly the same. The whole point of a tech pack is to communicate how your design is to be made. You start off by having a 'Technical Drawing' of your design, a front a back and if there are any details that need to be zoomed in and visualized further, you make a technical drawing of them too. To that drawing you point out the seam types and the 'Construction Details' of how the garment should be put together, using which seams. Next, you have a list or 'Bill of Materials' that are needed to put your garment together. Fabrics, trims, labels... A 'Graded Spec' of detailed measurements of the garment are also included in the tech pack in all the sizes that you offer.

In the initial stages of development you often don't have all the info yet, or you need it to be developed/sourced. In this case fill in the info you DO have and add "TBD" (to be determined) in RED , so you know to add this later. Use Instructions such as "VENDOR SOURCE", "SEE SEPARATE PAGE FOR DETAILS", etc. Then add reference images and detailed instructions of the item to get the development started. Update the info onto your tech pack as approvals are made.

Utilize lines with Arrows to point out where measurements are located on the garment. It should be visually clear to understand to overcome language barriers.

If desired you can Also include images of how you want the garments folded, hung, where you want the hangtags and inside labels positioned, etc.

Give detailed measurements (with arrows) for placement on a sketch of any artwork, appliques, etc. Note how far down from HPS (high point shoulder), WB (waistband) etc, as well as how far away from SS (Side Seam. For some items it will make more sense to give a measurement UP from HEM, such as a logo label on a T-shirt. It is also good to provide SCALE on how much bigger or smaller a graphic will get on Larger and smaller size ranges. 10% is usually a good starting point.

Most Companies, have their own set of Guidelines. If you are just starting out don't get overwhelmed, you can ask to see theirs and make adjustments as needed to fit the standards of your brand/ product. Adapt as needed as more experience is gained.

Tech packs can be overwhelming sometimes, so detailing the important points within a proper layout is the key to execute sample successfully. Making sure the details are loud and clear without any error and unnecessary noise. Before releasing a tech pack it has to be reviewed from a layout point and make sure all the visual instructions are placed correctly. Most importantly when providing references for the construction and finishing it should be clear enough to avoid any possible mistake. For example use of bold highlighting colors and references, right fonts and its size make the reader easy and comfortable.
