What a Marker Is and What Marker Efficiency Measures
Before fabric is cut for a garment order, the cutting room plans how to place each pattern piece on the fabric. That plan is called a marker. It is a layout of the front, back, sleeve, hood, pocket and other pieces for one or more garments, drawn at full size on a long strip the width of the fabric. The fabric is then laid out in many layers, called a lay, and the marker is placed on top so the pieces can be cut together.
Marker efficiency is the share of the marker area that is covered by pattern pieces. If the pieces fill most of the marker, little fabric is wasted. If there are large gaps between them, more fabric ends up as offcuts. The figure is shown as a percentage, and a higher one means less waste. It is one of the main factors in fabric consumption, which is the amount of fabric the factory uses per garment.
If you want to turn consumption into a quantity of fabric, our fabric consumption calculator shows the arithmetic, and this guide explains the layout behind the number.
How Marker Efficiency Is Calculated: A Worked Example
The calculation is simple. Take the area of all pattern pieces in the marker and divide it by the area of the marker, which is its length times the usable fabric width. The example below uses placeholder numbers to show the method. They are not typical figures for any garment and should not be copied.
Worked example of the calculation (placeholder figures)
| Item | Value | How it is found |
|---|---|---|
| Marker length | 2.40 m | Chosen by the marker planner |
| Usable fabric width | 1.50 m | Cuttable width of the fabric |
| Marker area | 3.60 square metres | 2.40 multiplied by 1.50 |
| Area of all pattern pieces | 3.06 square metres | Sum of the pieces in the marker |
| Marker efficiency | 85 per cent | 3.06 divided by 3.60 |
| Waste area | 0.54 square metres | 3.60 minus 3.06, which is 15 per cent |
Illustrative arithmetic only: 2.40 x 1.50 = 3.60, and 3.06 / 3.60 = 0.85. Placeholder figures to show the method, not an industry average.

From the worked example: 3.06 of 3.60 square metres is covered by pattern pieces. A teaching illustration, not a benchmark.
What Changes Marker Efficiency
Several things move the figure up or down. The shapes of the pattern pieces matter, because curved and angular pieces leave awkward gaps while straight-edged pieces tuck together. The number of sizes in one marker matters, because a mix of large and small pieces lets small ones fill the gaps around larger ones. Fabric width matters, because the pieces must fit across it, and a width that suits the pattern gives better efficiency than one that leaves a thin strip unused.
Fabric characteristics also set limits. A directional print, a one-way pile or a stripe that must match restricts how pieces can be turned, which lowers efficiency. Cotton jersey with a nap or shading may need all pieces to run the same way. Our guide to fabric width and cuttable width explains why the usable width is smaller than the quoted width.

Marker Efficiency and Fabric Consumption in Your Quote
Consumption is the fabric used per garment, usually shown in metres or kilograms. It is built from the area of the pattern pieces plus the waste implied by the marker, plus allowances for shrinkage, end-of-lay losses and sampling. A better marker efficiency lowers consumption, and a lower consumption lowers the fabric cost per garment. That is why factories work hard on markers for large orders.
For a brand, the lesson is that the consumption in a quote is not a fixed truth. It depends on the pattern, the fabric width and the sizes ordered. If you change the fabric to a narrower width or add a directional print, the number can change. Knit fabric is often bought by weight, so see our fabric kg to metres calculator for the conversion, and read the bill of materials guide to see where consumption is recorded.

A simplified sequence. Factories may use CAD systems and their own allowances.
Manual Markers, CAD Markers and Automated Cutting
Markers can be planned by hand on paper, but most factories now use computer-aided design software to nest the pieces. CAD tools test many arrangements quickly and can produce better efficiency than a person working by eye. Cutting itself may be done with hand-held cutters for small runs, band knives for shaped pieces or automatic cutting machines for larger volumes. The tools differ in cost, accuracy and speed.
For a small order, the effort spent on an optimal marker may not repay itself, because the saving is only a few metres of fabric. For a large order, a gain of a percentage point can mean a significant amount of fabric. Ask the factory how it plans markers and whether the figure in your quote is based on a CAD marker or an estimate.
Cutting methods compared
| Method | Typical use | What to know |
|---|---|---|
| Hand cutting with a cutter | Small runs and samples | Slower and less precise on thick lays |
| Band knife | Shaped pieces from a lay | Accurate on curves, needs skilled operators |
| Straight knife | Cutting a lay into rough blocks | Fast but needs finishing cuts |
| Automatic cutter | Large volumes | High precision and repeatable markers |
A general guide. Factories choose the method to suit the order size and fabric.
Where Fabric Is Lost Besides the Marker
The marker is only one source of loss. End-of-lay waste occurs at the ends of each layer of fabric, where a short length is not enough for another set of pieces. Fabric defects such as holes or stains cause pieces to be cut around or rejected. Shading differences between fabric rolls may require pieces from different rolls to be kept apart. Sampling and cutting errors use a further share.
Together, these losses mean that real consumption is higher than the area of the pieces alone. Good factories track each source of loss and set an allowance for it. The point for a buyer is not to expect zero waste, but to ask how much waste is included in the quote and whether the number is justified by the pattern and fabric.

Questions to Ask a Factory About Markers
You do not need to plan markers yourself, but you should know what to ask. A factory that can explain its markers is usually in control of its fabric use. The checklist below gives questions for the first quote and for any later change of fabric or style.
Marker and consumption checklist
- Is the consumption in the quote based on a CAD marker or an estimate?
- What fabric width was assumed, and is it the cuttable width?
- Which sizes are mixed in one marker, and what size ratio was used?
- How much shrinkage and end-of-lay allowance is included?
- Will the allowance change if I order a different quantity or size ratio?
- How are fabric defects and shading handled in cutting?
- Does a directional print or stripe change the consumption?
- Can I see the marker or a consumption sheet for the approved style?
A general list. Add anything specific to your fabric.
Do not push consumption down by squeezing pieces or changing the pattern. A tight marker that cuts pieces off the grain can cause twisting and poor fit, and that costs more than the fabric you saved.
Marker Efficiency and the Cost of a Garment
Fabric cost per garment is consumption multiplied by the price of the fabric. Because the marker efficiency affects the first number, it affects the cost. Better efficiency does not mean a cheaper fabric, and it does not change the labour cost. It simply reduces the share of purchased fabric that ends up on the cutting-room floor. Our guide to clothing manufacturing cost explains how fabric sits among the other cost lines.
Efficiency also interacts with design decisions. A style with a large number of curved pieces, an oversized body or an extra panel can lower efficiency simply because the pieces are harder to nest. When you value-engineer a style, check whether a small pattern change would improve the marker, as discussed in the garment value engineering guide. Remember that fabric weight also matters, which is covered in our GSM guide.
