Measured on the person
Chest around the fullest part, waist, hips, height, inseam — taken with a soft tape on the body. Use these to choose a size and to describe who the garment is for.
Size & fit, measured right.
How to measure a garment, the difference between body and garment sizes, how grading works across youth, women’s and men’s, and a builder for your size run.

02Measurement hotspots
Tap a point. Measure it right.
Every number on a spec sheet is a line on a flat garment. Pick a garment, tap a numbered point and see exactly where the tape goes. Switch cm and inches any time.
Point 1 / 7
½ Chest
Lay the garment flat and smooth. Measure straight across, about 2.5 cm below the armholes, from side seam to side seam. Double it for the full chest.

03Body vs garment
Your body is not the spec sheet.
Two kinds of measurement get mixed up in almost every first brief. Knowing which is which saves a sample round.
Measured on the flat garment
½ chest, body length, sleeve, hem — taken flat on a finished piece. This is what the factory makes, grades and checks. Your spec sheet should be written in these.

04Reading a spec sheet
Sizes become a grid of numbers.
This is how a graded spec looks. The numbers are an example only — illustrative values to show the format, not Onyx Stitch’s size chart. Your chart is agreed per style.

Added to brief06Grading
Four fits, four sets of rules.
Grading scales the approved sample to every size using grade rules. Size ranges shown are common examples; yours are listed in the brief and agreed per style.
Youth
Proportions change, not just size: shorter bodies and sleeves relative to chest, smaller neck openings. Graded from a youth sample size.
Women’s
Shaped through the waist and hip, narrower shoulders, adjusted armholes and lengths. A women’s fit is its own pattern, not a small men’s.
Men’s
Straighter body, broader shoulders, longer sleeves. Usually graded from an M sample size.
Unisex
One straight pattern for everyone, common in streetwear and merch. Many brands offer it alongside a women’s fit.
Size ranges are examples. Extended sizes can be discussed in your brief.
07Sending your size chart
A chart we can build from.
- 01
Measure three, not one
Measure three pieces of your reference garment and use the average — single garments vary.
- 02
Lay it flat, do not stretch
Smooth the garment on a table, buttons and zips closed, and measure relaxed.
- 03
Name your points
Use the names on this page (½ chest, body length from HPS…) so everyone measures the same line.
- 04
Send a spreadsheet
Sizes across the top, points down the side, in one unit. Add a photo showing each point.
- 05
Say how it should fit
Slim, regular, relaxed or oversized — and who wears it. Numbers plus intent beat numbers alone.
- 06
Include tolerances if you have them
Otherwise they are proposed per point and agreed per style.
08Before you enquire
Size & fit FAQ.
Straight answers. Anything commercial — minimums, timing, prices — is set per style and confirmed in your quote.
Do you have a standard size chart?
Size charts are agreed per style. You can send your own chart, a reference garment to match, or ask us to develop one for your market; it is confirmed on the sample before production.
Should I send body measurements or garment measurements?
Garment measurements — taken flat on a finished garment — are what the factory makes and checks. Body measurements help you choose sizes and define fit, and the difference between them is the ease.
What is grading?
Grading scales a pattern from the sample size to every other size using grade rules — how much each measurement changes per size. Youth, women’s and men’s fits use different rules, not just smaller or larger versions.
What measurement tolerance is acceptable?
Tolerances (how far a finished measurement may vary from the spec) are agreed per style and measurement point, and written into the spec sheet for quality checks.
Can you match the fit of a garment I already sell?
Yes. Send the garment or its measurements; the pattern is made to match and you approve the fit on a sample.
How do I plan my size run?
Start from your sales history or your squad list. Our size-run builder on this page totals quantities per size; minimums are set per style and confirmed in your quote.
Do you make youth and plus sizes?
Youth, women’s, men’s and extended sizes can be graded from the same design. List every size you need in the brief.
