UK Size Chart: Jackets & Hoodies

Body Sizes

Start from the body,
not from the garment

These are body measurements — the person, not the jacket. Every finished-garment table further down maps back to this one. UK and EU numbering are both shown because a brand selling on both sides of the Channel from one stock holding should print both on the size label rather than leave the customer guessing.

Read the ranges, not the letters. S, M and L mean different things at every brand. A customer who knows their chest is 104cm can order correctly from the range column even if your L is someone else’s M. Publishing this table on your own product pages is the single cheapest way to cut size-related returns.

Block 01

Pullover hoodie

Measured flat, closed, with the garment relaxed. Letters on the drawing correspond to the rows in the table.

Block 02

Technical shell jacket
finished garment

A lined, full-zip technical jacket cut with enough ease to layer a fleece underneath. This is the block most of our UK shooting and country outerwear is built on.

Block 03

Lightweight jacket
finished garment

Unlined, full-zip, cut closer than the shell block. Suits a summer smock, a packable shell or a lighter countrywear piece.

How To Read It

Five conventions that stop
an argument at inspection

Half measurements across, full measurements down

Chest, waist, hem and shoulder are half measurements: the garment laid flat and measured edge to edge across one face. Body length, sleeve length and hood height are full measurements. Double a half measurement to compare it with a body circumference. Getting this wrong is the most common single error in a first tech pack.

Every point has a defined origin

Chest is taken 2.5cm below the armhole. Body length runs from the high point of the shoulder to the hem. Sleeve is measured from the centre back neck along the shoulder and down to the cuff edge. Shoulder is seam point to seam point across the back. If your own chart defines them differently, tell us before sampling rather than after.

Grading is +3, +2, +1

Chest grades 3cm per size on the half measurement, body length 2cm, sleeve 1cm. That is a standard outerwear grade and it holds across the range. If you want a shorter body on the larger sizes, or a longer sleeve on the smaller ones, we change the grade rule rather than fudging individual sizes.

Tolerance is stated, not implied

Plus or minus 1cm on chest and body length, plus or minus 1.5cm on sleeve. Fabric relaxes and shrinks differently after wash and press, and a chart with no tolerance is one nobody can be measured against. Anything outside it is a QC failure here, not a discussion with you.

Confirm the numbers against your own pattern

These blocks are what we produce to as a default. If you already sell a garment that fits the way you want, send it — we will measure it, write the chart from it and grade it properly, and your customers will never notice a change in fit between one season and the next.

Sizing FAQ

Questions about UK sizing

Are these half measurements or full measurements?

Half measurements, taken with the garment laid flat and closed. Chest is measured across the garment 2.5cm below the armhole from edge to edge; to compare with a body chest measurement, double it. Length and sleeve figures are full measurements, not halved. This is the standard convention in a factory tech pack and it is where most confusion between a brand and a supplier begins.

How much ease should there be over the body measurement?

It depends on the garment and how it is meant to be worn. A close-fitting base layer sits near the body measurement; a country jacket expected to go over a jumper needs 12 to 20cm of ease across the full chest. The finished-garment tables below already carry the ease for each block. If you want a slimmer or roomier fit, change the finished garment figure, not the body size it maps to.

What tolerance do you work to?

Plus or minus 1cm on chest and body length, and plus or minus 1.5cm on sleeve length, measured on the finished garment. Fabric behaves differently after washing and pressing, so a chart with no stated tolerance is a chart nobody can be held to. Anything outside tolerance is a QC failure at our end, not a discussion at yours.

Can you produce to our own size chart instead?

Yes, and if you already have one that is what we would rather use. Send your graded specification and we build the pattern to your rules. If you only have a garment that fits the way you want, send that instead and we will measure it and write the chart for you.

Do UK and EU sizes really differ?

For outerwear the numbering does. A UK 40 chest is commonly labelled 50 in continental sizing, and the same garment may be an M or an L depending on the brand. The table below maps our blocks against both. If you sell into Britain and Europe from one stock holding, print both numbers on the size label rather than making the customer guess.

Is this chart for men, women or both?

These three blocks are mens outerwear. A ladies jacket is not a graded-down mens jacket — the shoulder, bust and waist shaping all differ and it needs its own pattern and its own chart. We produce ladies blocks separately and will send the equivalent chart on request.

Want this built to your grading?

Send us your own size chart, or a garment that fits the way you want. We build the pattern to your rules and send a graded sample set before bulk.
