Hoodie Tech Pack: Example, Measurements and BOM (2026)
A hoodie tech pack is usually six to eight pages: front and back flats, about 20 points of measure with a tolerance on each, a bill of materials of roughly 15 lines, and construction notes with stitch codes. Below is every page, filled in for one real-world style, a 400gsm drop-shoulder pullover, so you can see what a factory expects rather than a blank template.
The example numbers on this page are a starting point for a boxy, oversized fit. Change them to suit your garment, and have a technologist or your factory read the pack before anything is cut.
What a hoodie tech pack contains
A factory reads a pack in a fixed order: what the style is, what it looks like, what size it is, what it is made of, how it is sewn. For a pullover hoodie that comes to these pages.
| Page | What it holds | Hoodie-specific detail |
|---|---|---|
| Cover | Style number, name, season, version, date, your contact | Version number matters: you will revise after the first sample |
| Flats | Front, back and side line drawings with callouts | Show the hood up and down, and the inside of the hood if it is lined |
| Measurements | Points of measure for the base size, with tolerances | Say whether the rib is measured relaxed or stretched |
| Grading | The same points across the size run | Chest and length grow; neck drop and rib height usually do not |
| Bill of materials | Every fabric, trim, label and packaging item | Body fabric, rib and hood lining are three separate lines |
| Construction | Stitch types, seam allowances, order of assembly | Pocket attachment and hood seam are where factories guess |
| Artwork | Print or embroidery size, position, colour, method | Position measured from a fixed point, not "centred, roughly" |
| Labels and packing | Label positions, fold method, polybag, hangtag | Fibre composition label is a legal requirement in the UK |
A plain hoodie with no artwork can drop to six pages. Add a zip, a print and a second colourway and it is closer to ten.
If you want the wider picture first, read what a UK clothing factory actually needs from you. The tech pack is the first item on that list.
The measurements: 19 points for a size M hoodie
The measurement page is the one that decides fit, and it is where most first packs are thin. A hoodie needs around 19 points of measure. Fewer than a dozen and the factory is filling gaps for you.
This is a worked example for a drop-shoulder pullover, base size M. All values are in centimetres, garment laid flat, rib relaxed. HPS means high point shoulder: where the shoulder seam meets the neck.
| # | Point of measure | Size M (cm) | Tolerance |
|---|---|---|---|
| 1 | Body length from HPS, including hem rib | 72 | ±1.0 |
| 2 | Chest width, 2.5cm below armhole | 62 | ±1.0 |
| 3 | Hem rib width, relaxed | 52 | ±1.0 |
| 4 | Shoulder width, seam to seam | 60 | ±1.0 |
| 5 | Sleeve length from shoulder seam, including cuff | 58 | ±1.0 |
| 6 | Armhole, measured straight | 27 | ±0.5 |
| 7 | Bicep width, 2.5cm below armhole | 24 | ±0.5 |
| 8 | Cuff opening, relaxed | 11 | ±0.5 |
| 9 | Cuff rib height | 7 | ±0.3 |
| 10 | Hem rib height | 7 | ±0.3 |
| 11 | Neck width, seam to seam | 21 | ±0.5 |
| 12 | Front neck drop from HPS | 10 | ±0.5 |
| 13 | Back neck drop from HPS | 2.5 | ±0.3 |
| 14 | Hood height, neck seam to top | 36 | ±1.0 |
| 15 | Hood width at widest point | 26 | ±1.0 |
| 16 | Pocket width at base | 34 | ±0.5 |
| 17 | Pocket height | 18 | ±0.5 |
| 18 | Pocket opening length | 16 | ±0.5 |
| 19 | Pocket base, up from bottom edge of hem | 12 | ±0.5 |
Three things in that table do more work than they look.
The tolerance column. A chest of 62cm means nothing until you say whether 61cm passes. Without tolerances you have no grounds to reject a bad batch.
The words after the comma. "Sleeve length" is ambiguous on a drop shoulder. From the shoulder seam it is 58cm; from centre back it is 88cm. Say which, or you will get the wrong one.
Relaxed or stretched. Rib measures several centimetres wider when pulled. State it once at the top of the page and it covers every row.
The quickest way to get your own numbers is to lay a hoodie you like flat on a table and measure these 19 points with a tape. A garment you own is a specification waiting to be read.
Grading across sizes
Grading is how each measurement changes from one size to the next. It is not a percentage. Chest might grow 2cm from S to M and 3cm from M to L, while the front neck drop and rib heights stay the same in every size. Your pack needs either the full table for every size, or the base size plus the grade rule for each row.
The bill of materials: 14 lines
The bill of materials (BOM) lists everything the hoodie is made of. Every line you leave out is one the factory picks for you, and they will pick what is already in the building.
| Ref | Component | Specification | Qty per garment |
|---|---|---|---|
| F1 | Body fabric | 400gsm loopback jersey, 100% cotton. Body, sleeves, outer hood, pocket | Factory confirms |
| F2 | Hood lining | Self fabric, or a lighter single jersey to cut bulk | Factory confirms |
| F3 | Rib | 2x2 rib, cotton with elastane, dyed to match body. Cuffs and hem | Factory confirms |
| T1 | Drawcord | 8mm flat cotton cord, about 130cm, ends finished | 1 |
| T2 | Eyelets | Metal, with washers, finish stated (for example matte black) | 2 |
| T3 | Eyelet backing | Fusible interfacing patch behind each eyelet | 2 |
| T4 | Neck tape | 10mm cotton tape covering the back neck seam | By length |
| T5 | Sewing thread | Polyester, colour matched to body | By consumption |
| L1 | Main label | Woven, position stated (centre back neck) | 1 |
| L2 | Size label | Woven or printed | 1 |
| L3 | Composition and care label | Fibre content, care symbols, country of origin | 1 |
| P1 | Polybag | Size and thickness stated, warning text if required | 1 |
| P2 | Hangtag | Card, with string or pin | 1 |
| A1 | Artwork | Print or embroidery file, size, position, colour references | As designed |
Four notes on that table.
Fabric needs three facts, not one. "Heavy cotton" is not a specification. Give the weight (400gsm), the construction (loopback, also called French terry, or brushed-back fleece) and the composition (100% cotton, or 80/20 cotton-polyester). The same weight in a different construction is a different garment.
Rib is its own fabric. It is knitted and dyed separately from the body, so it will not match by default. Write "dyed to match" and ask for a lab dip, which is a small dyed swatch you approve before bulk.
Colour needs a reference. Give a Pantone code for the body, the rib, the drawcord and the thread. "Black" covers more shades than you would accept side by side.
Leave the cost column to the factory. Fabric consumption and unit prices depend on their fabric width, their cutting layout and your quantity. Nobody can fill those in honestly except the people quoting.
On L3: under the Textile Products (Labelling and Fibre Composition) Regulations 2012, clothing sold in the UK must carry a label stating fibre composition. Size and care instructions are not mandatory under that regulation, though almost every brand includes them (Compliance Gate).
Construction: how it is sewn
Construction notes tell the factory which stitch goes where. Factories use the numbered stitch types in the ISO 4915 standard, so a pack that says "514" is read the same way in Leicester and in Guangzhou. You only need three for a basic hoodie.
| Stitch | Plain-English name | Where it goes on a hoodie |
|---|---|---|
| 514 | Four-thread overlock | Joining seams: shoulders, sleeves, side seams, attaching cuffs and hem rib |
| 406 | Twin-needle coverstitch | Topstitching over shoulder, armhole and hood seams so they lie flat |
| 301 | Lockstitch (ordinary straight stitch) | Pocket, drawcord channel, labels, neck tape |
A typical construction page for this style would then say:
- Shoulder, armhole, sleeve and side seams joined with 514, then topstitched with 406
- Kangaroo pocket: edges turned under and attached with 301, reinforced with a bartack at each opening corner
- Hood: two panels joined at the centre with 514 and topstitched; lined; front edge turned to form the drawcord channel
- Eyelets set through the interfaced hood front before the channel is closed
- Back neck seam covered with tape, sewn with 301
- Cuffs and hem rib attached with 514, seam facing up into the body
State your seam allowance and stitch density too. If you do not, the factory uses its house standard, which is usually fine, but ask what it is and write it into the pack so the next factory matches it.
The usual order of assembly is: pocket onto front, shoulders, sleeves, side seams, hood, hood to neck, cuffs and hem, labels, drawcord. Your factory may change the order to suit their line. That is normal, and worth letting them do.
Six mistakes that are specific to hoodies
- Naming the weight but not the fabric. 400gsm loopback and 400gsm brushed fleece feel and drape differently. Give weight, construction and composition.
- Ignoring shrinkage. Cotton fleece shrinks in the wash. Say whether your measurements are before or after washing, and ask the factory for the fabric's shrinkage figure.
- Measuring rib stretched. A cuff measured pulled tight gives a number the factory cannot reproduce. Relaxed, always, and say so.
- Leaving body length ambiguous. "72cm" could include the hem rib or stop above it. A 7cm rib makes that a 7cm error.
- Under-specifying the hood. Height, width, lined or unlined, two panels or three. A hood with no numbers comes back small and flat, because that uses the least fabric.
- Vague artwork placement. "Centre chest" is a guess. "Top of print 8cm below the neck seam, centred, 28cm wide" is an instruction.
All six are the same mistake in different places: a detail left unstated, which the factory then decides for you.
Three ways to get a hoodie tech pack made
| Route | Typical cost | What you need | Best when |
|---|---|---|---|
| Buy a template and fill it in | About $5 for an Illustrator hoodie template | Adobe Illustrator, and your own numbers for every field | You already know the vocabulary and have the software |
| Hire a freelance technical designer | £180 to £300 for a simple garment in the UK | A clear brief and reference images | You are about to place a real order and want an experienced eye |
| Draft it with an AI tool, then have it checked | £29 a month for three packs with Seamix; the first is free | A plain-English description of the garment | You are early, testing ideas, or working through several styles |
The freelancer figures come from our guide to what a tech pack costs in the UK, which has the full breakdown.
A template gives you the boxes but not the numbers. If you can't draw or use Illustrator, it also gives you a file you cannot open.
With Seamix you type what the hoodie is and get back the pages above: flats, a graded measurement chart, a bill of materials and stitch-coded construction notes. You can see every page of a real pack before you sign up. It is a draft. It does not know your factory or your mill, so someone who does still needs to read it before it goes out.
Why the pack is worth getting right
A hoodie sample made in the UK costs roughly £80 to £200 or more, before pattern costs, and most garments take two or three samples to reach production (Make it British). Every vague line in your pack is a candidate for an extra sample. A complete pack is the cheapest way to take one of those rounds out.

Common questions
How many pages should a hoodie tech pack be?
Six to eight for a plain pullover. Length is not the test. The test is whether a stranger could make the hoodie without phoning you.
What measurements does a hoodie tech pack need?
Around 19 points of measure: body length, chest, hem, shoulder, sleeve, armhole, bicep, cuff, the neck opening, the hood and the pocket. Each one needs a tolerance.
What GSM is a heavyweight hoodie?
There is no official threshold. Brands commonly describe fabric of about 350gsm and above as heavyweight, and 400gsm or more is typical for premium streetwear. Weight alone is not enough: state the construction and composition too.
Is a zip hoodie tech pack different?
The structure is the same, with extra lines. Add the zip type, length, tape colour and puller to the bill of materials, and the zip setting method and front placket to the construction page. The pocket becomes two split pockets, each with its own measurements.
Can one tech pack cover several colours?
Yes. Add a colourway page listing the body, rib, drawcord and thread colour for each version. Remember that factory minimums usually apply per colour, so two colourways can mean two minimum orders.
Does a hoodie tech pack include the pattern?
No. The tech pack is the specification. The pattern is the set of shapes the fabric is cut from, and most factories make it themselves from your pack.
