Petite and Tall Grading: Why Length Is Not a Size

A petite size is not the size below, and a tall size is not the size above. Both keep the circumference grade and move the length axis only, so the same body is served by a second set of points, not by a different size. This page covers which points move, how the length is divided, and what a second set adds in pattern and sample work.

Why is a petite size not the size below?

The letter on the label is a position in a run, not a description of proportion. Take the size below and call it petite, and the chest, waist and hip all come down with the hem: you have sold a smaller body, not a shorter one. The same mistake runs upwards, where a tall cut from the size above arrives with a wider chest and a waistband cut for a bigger body. The circumference grade must not move. That is the reverse of the correction on our plus size grading and fit page, where circumference grows and the length points follow it.

The size range and the length sets are two separate decisions. A range is set first — XS to 3XL as standard, graded to your market’s size chart, with 4XL–5XL on request — and a length set is a second cut of those same sizes, so it keeps the letters and moves the points. The hoodie manufacturer page sets out the range in full. What a chart has to carry before a range can be set, and how it crosses markets, is on our clothing size conversion page.

Which points of measure carry a length axis?

Five points do the work. On a top they are body length, sleeve length and armhole depth; on a bottom they are rise and inseam. Everything else holds, which is what separates a length set from a new size. A chart that moves the hem and nothing else produces a shorter garment, not a petite one.

Point of measure	Petite set	Tall set	Held at the base grade
Body length, high point of shoulder to hem	Shorter at the hem, waist line held	Longer, split above and below the waist	Hem sits at the hip, or over the knee
Sleeve length, shoulder point to cuff	Shorter from the shoulder point, cuff at the wrist	Longer from the shoulder point, cuff at the wrist	Cuff finishes above the wrist bone or over the hand
Armhole depth, shoulder to underarm	Shallower, so the underarm stays close	Deeper as the body grows	Armhole sits low on a petite, high on a tall
Rise, waist to crotch	Reduced with the body, not with the waist	Increased front and back	Crotch sits low and drags the waistband down
Inseam, crotch to hem	Shorter between knee and ankle	Longer between knee and ankle	Hem stacks at the ankle or clears the shoe

Read the table by row. Each row is a decision taken before a pattern is cut, and a set that moves four of the five comes back as a fit complaint.

How should the added length be divided?

A tall request answered at the hem alone moves every landmark below the waist. The waist seam drops, the pocket lands on the thigh, the knee break sits above the knee, and the garment reads as a longer piece rather than a taller fit. The length has to be shared: above the waist, below it, and on the sleeve. On a bottom the share goes to the knee position and the inseam. The effect is louder in a 240–550 gsm fleece, where the hem carries more weight.

Shortening runs the same rule in reverse. Lifting the hem without lifting the knee break leaves the break below the knee, and shortening from the cuff instead of the shoulder point walks the cuff detail up the forearm.

Why must armhole depth come up on a petite set?

Armhole depth is a length measured down from the shoulder, so it belongs to the length axis, and it is the point most often left alone because it still measures correctly against the base chart. Hold it while the body shortens and the underarm sits proportionally lower: the side seam under the arm ends up shorter than the armhole is deep, and lifting an arm takes the garment with it. A shallower armhole with a matching sleeve cap keeps the underarm where the wearer’s is.

How are rise and inseam handled on a bottom?

A bottom carries two length points and they are not interchangeable. Rise sets where the waistband sits relative to the crotch; inseam sets where the hem sits relative to the knee. On a petite set the inseam takes most of the reduction and the rise a smaller share, so the waistband stays at the waist. On a tall set both grow, with the rise gaining at front and back. Waist, hip, rise and inseam are confirmed on the sample before the range is graded, as the yoga wear manufacturer page describes.

Where does a length axis get written down?

In the size range field of the tech pack, one line per length set: the run, the size the set was fitted on, and what each of the five points does from there. The knitwear tech pack template gives that field a row of its own. If the field names one run only, the pattern room has nothing to grade a second set from and will shorten the hem, because that is the only instruction on the page.

Does a second length axis mean a second style?

No. A length set is the same design graded on a second axis, so it counts as one style beside the standard run: 100 pcs per style, per colour covers base, petite and tall together. We accept plus size, petite, tall and special measurements, and the split across sizes is agreed when the quotation is drawn up, as the 100 piece order page sets out.

Which sample round proves a length set?

The size set, and each length set needs its own. A base run proved end to end says nothing about the petite set, because the points that move are the points measured there. Ask for the shortest and longest garment in each set to be measured and worn before release, and plan the first sample at 3–7 working days from an agreed tech pack. The sample types and rounds guide places that work in the sequence.

What has to be in the RFQ?

Name each length set, the run inside it, and the pieces per set. An extended run, a long inseam or a tall fit needs grading, and grading that never appeared in the RFQ arrives as an unexplained line in the quotation, as the RFQ fields page puts it. A quote built on one run and then asked to grade two more has to be rebuilt, and the rebuild lands in the weeks before sampling. A complete table comes back with a feasibility reply and a preliminary costed quote within 24 hours, so a second length set can be settled while the first quote is still open.

How is length checked before the cartons close?

Point by point, against the chart for that set, with a tolerance written for each point instead of carried over from the base set. A hem inside tolerance on the base run can sit outside it on a petite set, because the same allowance is a larger share of a shorter length. Inspection ends the chain rather than planning it: 100% inspection, accepted to AQL 2.5, measured against the size spec on a pull of each set, as the AQL 2.5 inspection page sets out.

What do buyers ask most about petite and tall grading?

Can you produce petite and tall in the same style?

Yes. Any size set you specify is graded on US, EU or Asian sizing, and petite and tall can sit in one style beside the standard run. Send the run you intend to sell and the chart your market uses, and both length sets are graded from the fit you already approved rather than from the size next door.

Is a petite size the same as the next size down?

No. The next size down reduces the chest, waist and hip as well as the length, so it fits a smaller body. A petite set keeps the circumference of the size letter and takes length out of the body, the sleeve, the rise and the armhole. Sold as the smaller size, it comes back as a complaint from a customer who was never the wrong size.

Does a second length axis change the minimum order?

No. Base, petite and tall are the same design on a second axis, so they count as one style and one minimum: 100 pcs per style, per colour. Special measurements are accepted on the same basis. Bring the run you intend to sell and the split across sizes to the quotation.

Do petite and tall each need their own sample?

Each set needs its own size set. The points that move on a petite or a tall set are not the points proved on the base garment, so an approved base sample says nothing about the shortest or longest version. Measure and wear both ends of each set, and allow 3–7 working days for the first sample from an agreed tech pack.

Why does a tall size keep the waist in the same place?

Because the waist is a body landmark, not a fraction of the garment. Put the whole of the extra length below it and the waist seam drops towards the hip, taking pockets, belt loops and the waistband of a bottom with it. Splitting the length above and below the waist keeps the landmark where the wearer expects it.

What should the RFQ say about petite and tall?

Name each length set, the run inside it, and the pieces per set. Say whether you want petite, tall or both, and attach the chart with the measurement for each point. An RFQ that lists one run and later asks for a tall set turns grading into a line in the quotation that nobody can check or price.

Tell us which length sets you want, the run inside each, and the chart your market buys against. First sample takes 3–7 working days, and bulk takes 15–25 days after sample approval and deposit. The plants run 18,000+ m² with 180+ staff and 150,000–200,000 pcs per month, so a length error caught at sampling is corrected before the cutting table.
