What Grade Rule Spacing Works for Linen Dresses and Shirts?
For linen shirts and dresses, grade 5 cm (2 in) at the chest or bust, 4.5 cm at the waist, 5-5.5 cm at the hip, 1-1.2 cm at the shoulder, and only 1-1.5 cm at body length per size. That last number is the one buyers get wrong: a knit or a polyester woven often takes 2-3 cm of length per size, while linen drape makes a larger length step change the silhouette instead of the fit. Grade circumference wider than a jersey rule and length narrower, then validate the rule at the smallest and largest sizes, not the middle.
If you remember one ratio: on linen, circumference grows about five times faster than length per size step.
The Spacing Table: Dresses and Shirts
The values below are per single size step, applied to the pattern, for mid-weight linen in the 150-220 GSM band. They assume a regular or relaxed fit and a base size at M or 38. A fitted linen shirt with a defined waist sits at the lower end of each range; an oversized shirt or a tiered dress sits at the upper end.
| Grade point | Linen shirt (cm) | Linen dress (cm) | In inches | What to watch |
|---|---|---|---|---|
| Chest / bust | 5.0 | 5.0-5.5 | 2.0-2.2 | Keep 8-14 cm of total ease, graded not fixed |
| Waist | 4.5 | 4.5-5.0 | 1.8-2.0 | No stretch recovery; do not under-grade |
| Hip | 5.0 | 5.5-6.0 | 2.2-2.4 | Dresses need more hip than shirts |
| Shoulder width | 1.0 | 1.0-1.2 | 0.4-0.5 | Woven seam sits on a non-stretch edge |
| Across chest | 0.8 | 0.8-1.0 | 0.3-0.4 | Ties to armhole depth, not to bust grade |
| Armhole depth | 0.7 | 0.7-0.8 | 0.3 | Sleeve cap must gain the same amount |
| Neck width | 0.6 | 0.6-0.7 | 0.25 | Under-grading here causes a gaping collar |
| Sleeve length | 0.8 | 0.8-1.0 | 0.3-0.4 | Arm length scales slower than body width |
| Body length | 1.2 | 1.2-1.5 | 0.5-0.6 | The critical linen-specific number |
| Hem opening | 1.0 | 1.5-2.0 | 0.4-0.8 | Relaxed dresses need a wider hem to keep the fall |
Ranges assume 100% linen, plain weave or twill, with a settled shrink position. Confirm the exact increments against your own base block before the first sample cut.
Two structural notes on reading this table. First, the chest and waist steps are close together, within 0.5 cm. On a knit, a 4 cm chest step is often paired with a 4 cm waist step and the rib does the rest. On linen, the waist needs nearly as much room as the chest because there is no recovery: a garment that fits the bust but grips the waist will sit badly by the end of the day. Second, the armhole, across-chest and sleeve-cap numbers are a set. If you change one, the other two must change with it, or the sleeve will twist.
For the market-level chart these increments eventually produce, including the US, EU, UK conversions and how the same body is labelled in each market, see our guide to linen sizing for global markets. That article covers the publishing layer; this one covers the arithmetic behind it.
Linen Versus Cotton and Polyester Spacing
The most common grading error in linen programs is inherited spacing. A brand builds a jersey program, learns that 4 cm at the chest and 2.5 cm at the body works, then applies the same rule to a woven flax block because the numbers look plausible. They are not interchangeable.
| Grade point | Cotton jersey | Polyester woven | Linen woven | Reason for the difference |
|---|---|---|---|---|
| Chest step | 4.0 cm | 4.0-5.0 cm | 5.0 cm | Linen carries more ease that must itself scale |
| Waist step | 4.0 cm | 4.0 cm | 4.5 cm | No elastic recovery in flax |
| Hip step | 4.5 cm | 5.0 cm | 5.5 cm | Drape and garment weight |
| Body length step | 2.0-3.0 cm | 2.0 cm | 1.0-1.5 cm | Length reads as silhouette, not coverage |
| Shoulder step | 0.8 cm | 1.0 cm | 1.0-1.2 cm | Seam sits on a stiff, unforgiving edge |
| Shrink allowance | 2-4% | 0-1% | 3-7% | Must be settled before grading starts |
| Sleeve cap ease | 2-3 cm | 1.5-2 cm | 1.5-2.5 cm | Cap must track the armhole grade exactly |
Figures describe typical commercial practice, not a standard. Knit spacing varies with fabric stretch and negative ease; polyester woven with finish and coating.
If you use polyester spacing on linen, the symptom is a garment that fits at M and feels tight at XL across the chest, with an armhole that has not deepened enough and a collar that sits closer to the neck. If you use jersey length spacing, the symptom is a dress that is correct at M and mid-calf at XL when it was designed below the knee. Both defects pass a tape-measure check against the grade rule, because the rule itself was wrong.
The easiest sanity test: compare your proposed chest step against total ease. If a size step adds 5 cm of chest but only 0.2 cm of ease, the garment is effectively tightening as it grows. Ease should scale roughly in proportion to circumference, not stay flat.
How Shrinkage Changes the Effective Spacing
Linen typically loses 3-7% in the first wash. That single fact changes what your spacing means in practice, because a fixed percentage loss is a growing absolute loss. A 5% loss on a 96 cm chest is 4.8 cm; on a 116 cm chest it is 5.8 cm. Grade at a constant 5 cm and the finished chest difference between sizes quietly compresses at the top of the range.
There are only two clean ways to handle this, and one common mistake:
- Grade the cut pattern, publish the washed chart. Grade at 5 cm on the pattern, then subtract the measured shrink from each graded size to produce the published measurements. This works, but the shrink must be measured per size, because larger panels lose more in absolute terms.
- Grade the washed pattern. Apply the shrink allowance to the base block first, verify the washed base, then grade from it. Cleaner, and the method we recommend for any program above 500 pieces.
- The mistake. Grade the cut pattern, publish cut measurements, and add a note saying "allow 5% shrinkage". The buyer receives a garment smaller than the chart and the dispute lands on the factory even though the instruction was written into the spec.
A pre-shrunk or garment-washed finish drops shrinkage to roughly 1-3%. With less shrink to absorb, the chest step can relax slightly toward 4.5-5 cm and the length step can rise to 1.5-2 cm without the garment reading long. That is why the finish has to be locked before the rule is signed off: switching finish after grading means re-grading, and re-grading after sampling means a second sample round. The mechanics are set out in linen shrinkage control.
Read the Rule Across the Size Run
Spacing only makes sense in sequence. Here is what a 5 cm bust step and a 1.2 cm length step actually produce on a linen shirt graded from a 96 cm bust at M, with a 5% shrink allowance applied to the pattern and a published chart in washed measurements.
| Size | Cut bust (cm) | Washed bust (cm) | Cut length (cm) | Washed length (cm) |
|---|---|---|---|---|
| XS | 106 | 101 | 66.0 | 63.0 |
| S | 111 | 105.5 | 67.2 | 64.0 |
| M | 116 | 110 | 68.4 | 65.0 |
| L | 121 | 115 | 69.6 | 66.0 |
| XL | 126 | 119.5 | 70.8 | 67.0 |
| XXL | 131 | 124 | 72.0 | 68.5 |
Illustrative figures for a relaxed linen shirt. Cut bust includes garment ease; washed values assume 5% width shrinkage measured on the actual fabric, not a book value.
Two things become visible in this table that are invisible in a single-size spec. The washed step between XS and S is 4.5 cm while the step between XL and XXL is also 4.5 cm, but the cut step is a constant 5 cm, so any variation in shrink percentage between fabric lots lands directly on the chart. This is why we measure shrink on the bulk fabric and not on a reference quality.
Above roughly a 120 cm chest, bodies do not scale linearly. Shoulder width, armhole depth and waist-to-hip ratio all change, and a single rule stretched to 4XL produces a garment that fits the bust and misfits the shoulder. Extended sizes usually need a second rule and often a separate base block.
Six-Step Verification Before Bulk
1
Approve the base size in the final fabric. Same weave, same GSM, same finish. A cotton stand-in will not show you linen's drape or its shrink.
2
Wash the base sample once and re-measure after 24 hours. Record before and after at every grade point, not only the chest. Length and hip often move differently from width.
3
Cut one size up and one size down from the graded pattern. Fit both on the same model or a consistent mannequin. This is where sleeve twist and armhole binding appear.
4
Cut the extremes, XS and the top size. Errors that stay hidden at M and L are obvious at the ends of the run, which is exactly where returns cluster.
5
Wash the full set and compare against the published chart. Compare washed garment to published chart, never pattern to chart. That comparison is the only one the customer will ever make.
6
Version the rule and freeze it. Any later change to fabric, finish or fit gets a new version number. Silent edits to a live rule are how a reorder arrives a size different from the first order.
Sampling for a linen program typically runs 7-12 days per round, inside a 7-14 day window depending on fabric availability; with 50+ linen qualities in stock the first round usually lands at the fast end. Two rounds is the realistic plan for a new grade rule, one round for a carry-over block.
What to Send With the Rule
Grading disputes are almost always documentation disputes. Send these and the conversation shortens considerably:
Base size stated in both label terms and numeric measurements
The full size run, including any extended-size split
A grade table of increments per point per size
Measurement points defined by name or diagram
Tolerances per point: ±1 cm circumference, ±1.5 cm length
Shrink test report on the actual fabric, with wash condition
Fit intent per size, written not implied
Fabric width and shrink direction, for marker and costing review
If the tech pack is thin, expect the factory to fill the gaps with its own assumptions, and expect those assumptions to differ from yours. The full document set a linen factory needs before cutting is covered in tech packs for linen clothing.
Spacing Errors That Reach the Customer
Four failures worth screening for before approval:
- The waist under-graded. Chest grows 5 cm, waist 3.5 cm. The garment fits on the hanger and grips in wear. Most common on shirt dresses.
- Neck left at base size. Collar sits tight at XL and the front placket gapes. Neck width needs its own 0.6-0.7 cm step, and the shoulder slope usually needs a small adjustment above XL.
- Length graded like a knit. 2.5 cm per size turns a below-knee dress into a midi at XL and a mini at XS. Grade 1-1.5 cm and let width carry the difference.
- Linings and facings left ungraded. Shell grows, lining does not, and the vent pulls or the pocket bag tears. Grade every piece in the set, including interfacings.

For costing, remember that grading is not linear in fabric. Consumption per unit typically rises 15-20% from S to XL on a shirt, and 20-25% on a wide-leg trouser, because the leg panel is constrained by fabric width. Quote the average across the actual size break, and ask for per-size consumption so you can see where the cost steps up. Fabric is usually 30-45% of garment cost and labour 25-35%, so a 10% consumption increase moves landed cost by 3-4.5%.
Quick Answers
Is 5 cm too much for a linen shirt?
For regular and relaxed fits, 5 cm is the norm; oversized styles can take 5.5 cm. It is too much only when the base block already carries very heavy ease. Reduce to 4.5 cm and re-check the armhole before changing anything else.
Should the chart show washed or unwashed numbers?
Washed, measured after one wash at the care-label condition and 24 hours of relaxation. Publishing cut measurements while the customer washes the garment is the most common source of "it shrank" complaints on linen.
Can one rule cover XS to 4XL?
Rarely. Above roughly a 120 cm chest, shoulder, armhole and waist-to-hip relationships change. Use a second rule with adjusted steps, and expect extended sizes to need their own base block rather than more increments.
Does the weave change the spacing?
It changes drape more than measurement. A twill holds shape and takes a slightly smaller length step than an open plain weave of the same weight. Confirm the rule on the actual weave, not on a plain-weave reference.
What tolerance is realistic on linen?
±1 cm on circumference points and ±1.5 cm on length points at AQL 2.5. Linen moves between pressing and relaxing, so tighter tolerances reject good garments without improving the fit the customer feels.
