Fabric Shrinkage and Pre-Wash: What to Do Before You Cut
Pre-wash any fabric made from natural fibre — cotton, linen, silk, viscose — before you cut it. Synthetics like polyester georgette, satin and most velvets barely shrink and generally don't need it. The reason is blunt: fabric shrinks on its first wash, and if that first wash happens after stitching, the garment shrinks with the seams in it. A kurta that fits at the trial can come back a size smaller and an inch shorter, and nothing can be done about it.
This is the single most common cause of a garment "not fitting" when the tailoring was actually correct. It is entirely preventable, and it takes one afternoon.
What shrinks, and roughly how much
Shrinkage depends on fibre, weave tightness and how the fabric was finished at the mill. The figures below are working ranges for planning your cut — treat them as buffers to build in, not as guarantees for any specific piece.
| Fabric | Typical shrinkage range | Pre-wash needed? | Notes |
|---|---|---|---|
| Linen | 4-10% | Yes, always | The biggest mover of the lot. Shrinks more in length than width. |
| Soft cotton | 3-7% | Yes | Loose weaves shrink more than tight ones. May shrink a second time. |
| Viscose and rayon blends | 3-8% | Yes, gently | Weak when wet — handle with care, never wring. |
| Silk and banarasi soft silk | 2-5% | Steam or dry clean, not machine wash | Water can mark silk. Do not experiment on the good piece. |
| Georgette (polyester) | 0-2% | No | Silk georgette is a different matter — treat as silk. |
| Organza | 0-2% | No | Steam only. Washing can kill the crispness permanently. |
| Satin and fendi satin | 0-2% | No | Heat-sensitive. Low iron, press cloth. |
| Velvet (all types) | 0-3% | No — never wet-wash before cutting | Water crushes and marks the pile. Steam from the back only. |
Put that in real terms. A 3-metre cut of linen shrinking 7% loses roughly 21cm — more than the length of a sleeve. On a 44-inch width losing 5%, you drop over 2 inches of usable width, which can be the difference between getting a panel out of the piece and not.
Why pre-washing works
Fabric leaves the loom under tension. It is stretched during weaving, dyeing and finishing, and it holds that tension until water and heat let the yarns relax back to their natural length. That relaxation is the shrinkage. Wash it once and the fabric settles; cut it after that, and the dimensions you cut are the dimensions you keep.
Pre-washing also removes the sizing the mill applied — which is why some fabric feels stiff off the roll and softer after one wash, and why the drape you see on the roll is not the drape you'll get in the finished garment. It reveals dye bleed too, before that dye can run onto a lining.
How to pre-wash each type safely
Linen and cotton
Wash the same way you intend to wash the finished garment — that is the whole point. If you'll machine wash the kurta later, machine wash the fabric now, cold or lukewarm, gentle cycle, mild detergent. Dry it fully, then press it flat before cutting. Do not skip the drying: a lot of shrinkage happens in the dry, not the wash.
Serge or zigzag the raw cut edges before washing, or you'll be untangling a fringe of loose threads afterwards. Linen especially frays hard.
Viscose and blends
Hand wash in cool water with a mild detergent. Viscose loses a lot of strength when wet, so support the whole piece when lifting it out rather than pulling it by one corner, and never wring. Press the water out between towels and dry flat in shade.
Silk and banarasi soft silk
Do not machine wash. The safest pre-shrink for silk is steam: hover a steam iron just above the fabric, or hang it in a steamy bathroom, and let it relax without direct contact. If you intend to dry clean the finished garment, dry clean the fabric first — a pre-wash should always match the garment's future care, or it teaches you nothing.
Test on a spare corner first. Water spots on silk can be permanent.
Velvet, organza, satin, sequin and embroidery fabrics
Don't wet these before cutting. Velvet's pile crushes and water-marks; organza loses its crispness; satin can water-spot; sequin and embroidery work can come loose. Steam them gently from the reverse side instead, holding the iron above the fabric rather than resting on it. These move so little that skipping the pre-wash costs almost nothing.
Polyester georgette and synthetics
Optional. A cool gentle wash does no harm and removes finishing residue, but don't use heat — polyester takes a permanent crease from a hot iron the way natural fibres don't.
Buying with shrinkage in mind
Order extra. On linen, add roughly 10% over your tailor's figure; on cotton and viscose, around 5-7%; on synthetics, nothing. If your tailor says 2.5m of linen, order 2.75m and you'll still have the garment they measured for.
Fabric is cut to order from 0.8m to 5.5m, so you can ask for the exact buffered length rather than rounding to a fixed piece. Two things worth confirming before you place the order: the width shown on the product page, because 44-inch and 58-60 inch fabrics need very different metres for the same garment, and whether you need the whole requirement from one lot — dyed lots vary slightly, and a second order placed later may not match. For a garment with matching panels, or a set for two people, buy it all at once.
This matters most on linen and soft cotton, the two highest-shrinkage fabrics anyone commonly stitches. It matters least on velvet and satin, where washing before cutting will actively damage the piece.
For tailors, boutiques and resellers
Pre-washing is a cost of goods, not an optional step, and it belongs in your quote. One afternoon of washing and pressing per lot removes the most common category of remake request there is.
Run a shrinkage test on every new lot rather than trusting a general figure. Cut a 50cm square, mark a precise 40cm x 40cm inside it with tailor's chalk or a running stitch, wash and dry exactly as you'll instruct the customer to, then re-measure the marks. That percentage is your real number for that lot — and it can vary between two lots of the same fabric name.
What pre-washing does not fix
It doesn't stop linen and cotton from creasing — that's the fibre. It doesn't prevent a second, smaller shrink on loose-weave cottons, which sometimes move again on the second or third wash. And it doesn't undo a hot dryer or a hot iron later; a garment washed cold and then tumbled hot will still shrink. Whatever you pre-wash with is the routine that garment needs for the rest of its life.
FAQ
Do I really need to pre-wash if the fabric says pre-shrunk?
A pre-shrunk finish reduces shrinkage but rarely eliminates it, and a small residual movement is normal. For linen and cotton, a single wash before cutting is still worth it. For synthetics described as pre-shrunk, you can skip it.
How much extra fabric should I order for shrinkage?
Roughly 10% extra on linen, 5-7% on cotton and viscose, and nothing on polyester, satin or velvet. Ask your tailor for their base figure first, then add the buffer on top — and check the fabric width before converting that into metres.
Can I skip pre-washing if the garment will only be dry cleaned?
Not entirely. Dry cleaning causes far less shrinkage than water, but if you'll dry clean the garment, the right move is to dry clean the fabric once before cutting. The principle is the same: whatever the garment will go through, put the fabric through it first.
Should I pre-wash a saree or a ready garment?
No. Pre-washing is for uncut fabric. A finished saree or garment should be cared for according to its own care instructions — check the product page and any label rather than washing it on assumption, especially for silk, velvet and anything with embroidery or sequin work.
What if my fabric bleeds colour in the pre-wash?
That is exactly what the pre-wash is for — better it happens now than onto a lining in the finished kurta. Rinse until the water runs clear, wash that fabric separately in future, and for deep reds and indigos consider a cold wash with salt for the first cycle.
