How to Prepare a Sweater Tech Pack

A tech pack is the single document that turns your idea into a manufacturable sweater. A clear one gets you an accurate sample on the first try; a vague one creates rounds of costly back-and-forth and a product that drifts from your vision. This guide shows B2B buyers exactly what to include in a knitwear tech pack so a factory can quote and sample with confidence.

A tech pack is not paperwork. It is the contract between your idea and the factory's machines. The clearer it is, the closer your first sample lands.

Factories do not guess; they build to spec. Every detail you leave out becomes an assumption the factory makes for you, and those assumptions are why first samples disappoint. A complete tech pack also lets a factory quote accurately, because they can see the yarn, gauge and complexity before committing to a price.

Start with a clear sketch or a reference garment, front and back. A physical reference is the fastest way to communicate handfeel and construction. State clearly what to copy and what to change.

Specify fiber composition (for example 100% cotton, or 50% wool / 50% acrylic), yarn weight, and target gauge. If you do not know the exact yarn, describe the handfeel and let the factory propose options. See our yarn selection guide and gauge guide.

This is where most tech packs fall short. Provide a full measurement spec, by size, with tolerances (for example body length 70cm +/- 1cm). Include how each point is measured to avoid ambiguity.

Give Pantone references or physical swatches for each colorway. List every trim with placement, and state your folding, polybag and carton requirements so the factory can quote finishing accurately.

Before you send a tech pack, confirm:

• Sketch or reference shows front and back clearly
• Yarn composition and gauge are stated
• Stitch structure is described or shown
• Measurement sheet is complete for all sizes, with tolerances
• Colors have Pantone or swatch references
• Trims, labels and packaging are listed

Many emerging brands do not have a complete tech pack, and that is fine. A capable ODM factory can develop the spec with you from a reference garment and a brief. See how OEM and ODM differ in our OEM vs ODM guide. The clearer your input, the faster and cheaper the development.

To see why precision matters, take a single point of measure (POM) on a crewneck pullover and write it the way a factory needs it. A vague line like "body length about 70cm" forces an assumption; a complete line removes it:

The right-hand column tells the factory exactly where to place the tape, what number to hit per size, and how much variance passes QC. Apply that discipline to every POM — chest width, sleeve length, armhole, rib depth, neck width — and your first sample lands close enough to approve with minor comments rather than a full remake. Pair the spec sheet with a stitch and gauge note (anywhere from a chunky 3GG hand-feel to a fine 18GG) so graded measurements and knit density are read together, not in isolation.

A tech pack reads faster — and comes back as a tighter quote — when it uses the conventions and standards a factory already works to. The ones worth naming explicitly:

• Gauge is stated in needles per inch (NPI): 3GG–5GG for chunky, 7GG mid-weight, 12GG–14GG fine, up to 18GG for very fine knits. Always pair the GG number with the knit structure so density and hand-feel are read together.
• Yarn count: metric count Nm (for example 2/26Nm on a typical worsted-weight sweater) or cotton count Ne — state count and ply so the mill matches weight, not just fibre.
• Measurement tolerances (POM): the working convention is roughly ±1.0 cm on large points (body length, chest width) and ±0.5 cm on small points (neck width, rib depth), with graded increments of about 4–6 cm on chest between adjacent sizes. Write the tolerance next to every point of measure.
• Care labelling: specify symbols to ISO 3758 / GINETEX, and fibre content to your market's rule — the US FTC Textile/Wool labelling rules or the EU Textile Regulation (EU) No 1007/2011.

📌 The one line that saves a sample round: every point of measure needs three things beside it — a value per size, a how-to-measure method, and a tolerance. Miss any one and the factory has to assume — and assumptions are exactly what make first samples miss.

How much detail you need depends on where you are. Use this to calibrate before sending:

Across all three, our flow stays the same: a confirmed tech pack moves to sampling in 15–25 days from confirmed tech pack and yarn, and approved samples move to bulk in 30–45 days at MOQ from 30 pcs. The more you lock before sampling, the fewer paid sample rounds you spend. If you want a recycled-content program, flag it in the tech pack so we quote GRS-certified yarn (cotton, wool, merino, cashmere, blends, acrylic and recycled are all in scope), and note any OEKO-TEX Standard 100 requirement for the finished garment up front.

Do I need a finished tech pack before a factory will quote? No. We can quote from a reference garment plus your target sizes and colorways, then develop the full spec with you during ODM development. A complete tech pack simply makes the quote tighter and faster.

What is the single most common mistake in sweater tech packs? Incomplete measurement sheets — missing tolerances, missing how-to-measure notes, or only one size. Without graded POMs and tolerances the factory has to assume, and assumptions are what make first samples miss.

Can you match a yarn if I only know the look and feel, not the composition? Yes. Describe the handfeel, weight and target gauge and we will propose yarn options from cotton, wool, merino, cashmere, blends, acrylic or recycled fibers, including GRS-certified recycled yarn if sustainability is part of the brief.
