Stripes and Checks: How Much Extra Fabric to Add

Why a pattern costs extra length

On plain cloth a cutter nests pattern pieces wherever they fit. On a stripe or a check, each piece has to start at the right point in the repeat so the pattern runs continuously across the seams. Pieces get pushed down the roll to catch the next repeat, and the cloth skipped over is lost.

The bigger the repeat, the more gets skipped. A 3 mm pin stripe barely moves the number. A 50 mm window check can push a shirt's consumption up by a fifth.

How much to add

Take the plain-fabric meterage for the garment, then add the margin below on top of the usual 5 to 10 percent cutting wastage.

Where the pattern has to match

Not every seam needs matching, and knowing which ones do keeps the allowance sensible. A tailor who matches everything uses more cloth than the garment needs; one who matches nothing produces a uniform that looks wrong at a glance.

• Centre front, where the button placket closes: the most visible match on any shirt.
• Side seams at the chest and waist, where a break in the line reads immediately.
• Pocket to body: a patch pocket that does not match is the classic giveaway.
• Sleeve head to shoulder: usually matched on blazers, often accepted unmatched on shirts.
• Collar and cuffs: often deliberately cut on the cross or in a plain contrast instead.

Directional fabrics and one-way layouts

Some fabrics have a direction even without a visible pattern. A brushed or napped finish reflects light differently depending on which way the pile runs, so pieces cut facing opposite ways look like two different shades once the garment is made up.

These need a one-way marker, where every piece faces the same direction. That removes the cutter's ability to rotate pieces into gaps, which is where the extra 10 to 20 percent goes.

Getting it right before the order

Ask two questions before you finalise meters on a patterned fabric: what is the repeat size, and does the styling need matched pockets. Both are on the spec sheet or a quick call away, and both change the total.

For a bulk program it is worth running a trial marker on the actual fabric with the actual size ratio. It settles the real consumption in an afternoon instead of leaving you short halfway through cutting, which on a custom shade means a second dye lot and a visible shade step.

FAQ

Frequently asked questions

How much extra fabric for a checked uniform?

Add 10 to 15 percent for a medium check and 15 to 20 percent for a large check, on top of the normal 5 to 10 percent cutting wastage.

Do stripes need as much extra as checks?

No. A stripe only has to line up in one direction, so 5 to 10 percent usually covers it. A check has to line up both across and along the garment, which is why it costs more cloth.

What is a pattern repeat?

The distance before the design starts again. A 20 mm check repeats every 20 mm. The larger the repeat, the further a cutter may have to move a piece to reach the right starting point, and the more cloth is skipped.

Can we avoid the extra cost by not matching?

You can, and for some workwear it is a fair call. But mismatched plackets and pockets are the first thing people notice on a uniform, so it is usually worth the extra meters on anything front-of-house.

Does a school check need this allowance too?

Yes. School checks are typically in the medium range, so plan 10 to 15 percent extra. Junior sizes soften the total because the garments themselves are smaller.

Which of your fabrics are directional?

Brushed and peached finishes are directional, as are the larger checks and any fabric with a clear one-way surface. Ask us for the repeat size and the recommended layout for the specific quality you are considering.
