A fat quarter is a rectangular cut of fabric that gives sewists and quilters a wider, more useful shape than a long narrow quarter-metre strip. It is especially popular for patchwork, quilting and smaller sewing projects because the proportions make it easier to cut squares, rectangles and other shapes efficiently.

If you have seen fat quarters or fat quarter bundles in a fabric shop and wondered how they differ from ordinary fabric by the metre, this guide explains the sizes, uses and practical project possibilities. You can also browse our Fat Quarter Bundles to see coordinated pre-cut options.

What is a fat quarter?

A fat quarter is created by taking a larger piece of fabric and dividing it into quarters in a way that produces a roughly square-ish rectangle rather than a long strip. The exact method and finished dimensions depend on whether the starting fabric is measured in metres or yards and on the usable width of the fabric.

The advantage is shape. A conventional quarter metre cut across the full width of 110 cm fabric would be approximately 25 cm x 110 cm. A metric fat quarter from the same width is commonly around 50 cm x 55 cm. Both contain a similar area of fabric, but the fat quarter gives you more flexibility when cutting wider pieces.

What size is a fat quarter?

These measurements are common rather than universal. Fabric widths vary and some suppliers cut pre-cuts to their own specifications, so always check the product listing before planning a pattern around an exact size.

Why is it called a fat quarter?

The word “fat” refers to the proportions of the piece. Instead of receiving a skinny strip across the full width of the fabric, you get a broader rectangle. It is still approximately one quarter of the original metre or yard section, but the altered shape gives more usable width for patchwork and small pattern pieces.

Fat quarter vs quarter metre: what is the difference?

A quarter metre is usually cut as 25 cm of the full fabric width. A fat quarter is typically produced by cutting a half metre length and then dividing that piece across the width. This creates a shape around 50 cm long by half the fabric width.

Neither format is inherently better. A quarter-metre strip is useful when you need long narrow pieces such as binding strips. A fat quarter is often more convenient when you need wider squares, bag panels, patchwork blocks or multiple small pieces.

What are fat quarters used for?

Fat quarters are most closely associated with quilting, but they are useful for much more. Popular uses include:

• patchwork blocks and quilt tops;
• small tote bags and zipped pouches;
• fabric baskets;
• cushion panels and patchwork cushions;
• bunting;
• appliqué;
• small accessories and cases;
• fabric decorations;
• scrunchies and hair accessories;
• small reusable gift bags;
• children's craft projects.

Fat quarters are particularly useful when a project needs several prints rather than a large continuous length of one fabric.

Are fat quarters only for quilting?

No. Quilters love fat quarters because they are convenient for cutting blocks, but the format is equally useful for general sewing. A fat quarter can provide enough fabric for many small accessories, while a bundle gives you coordinated colours and prints that can be mixed within one project.

For seasonal sewing, for example, fat quarters can become ornaments, patchwork stockings, bunting or gift bags. If you are planning festive projects, see our guide to the best Christmas fabrics for sewing and quilting.

What can you make with one fat quarter?

The answer depends on the dimensions of both the fat quarter and the pattern pieces, but one piece can often be enough for a small project such as:

• a simple zipped pouch;
• a set of fabric coasters;
• small bunting flags;
• a fabric bookmark set;
• appliqué shapes;
• small patchwork components;
• hair accessories;
• small drawstring bags.

Before cutting, place all pattern pieces on the fabric or make a paper layout. Directional prints can reduce the number of pieces you can cut because motifs may need to face the same way.

How many fat quarters do you need for a quilt?

There is no single number because quilt sizes, block designs, seam allowances, borders and cutting waste all vary. A baby quilt made from large simple blocks may use far fewer pieces than a detailed double-bed quilt.

The safest approach is to work from a specific quilt pattern. If you are designing your own quilt, calculate the finished block count first, add seam allowances, then work out how many blocks can be cut from the actual fat-quarter dimensions. Allow extra for directional prints, mistakes and pattern matching.

How to choose a fat quarter bundle

A well-planned bundle can save time because the fabrics are already selected to work together. When choosing one, consider:

• Colour balance: do you have light, medium and dark values?
• Print scale: mixing large, medium and small prints often creates more visual interest.
• Project style: children's quilts, modern patchwork and traditional quilting can need very different combinations.
• Fabric composition: using similar fibres and weights can make patchwork easier to piece.
• Number of pieces: check that the bundle contains enough fabric for the pattern you want to make.

Do you need to pre-wash fat quarters?

There is no universal rule. Some quilters prefer not to pre-wash small pre-cuts because washing can create fraying and distortion, while others prefer to pre-wash cotton before a washable project. Follow the fabric supplier's care information and keep treatment consistent across the fabrics used in the same project.

Tips for cutting fat quarters efficiently

• Press the fabric before cutting so folds do not distort measurements.
• Square the edges only as much as necessary to avoid wasting fabric.
• Cut the largest required pieces first.
• Plan around directional prints before making the first cut.
• Save useful offcuts for appliqué, labels and scrap quilting.

Frequently asked questions

Is a fat quarter the same as half a metre?

No. A fat quarter is approximately one quarter of a metre-length section of standard-width fabric, rearranged into a wider rectangle. Half a metre contains roughly twice the fabric area.

Can I buy matching fat quarters?

Yes. Fat quarter bundles are designed to provide several coordinated prints or colours, making them convenient for patchwork and projects that require variety.

Are fat quarters good for beginners?

Yes. They are manageable in size, easy to store and ideal for learning accurate cutting and simple patchwork without committing to large lengths of fabric.

Can fat quarters be used for dressmaking?

They can be useful for pockets, trims, children's accessories or colour-blocked details, but most adult garments require larger continuous pieces. Always check the pattern layout and fabric requirements.

Start sewing with fat quarters

Fat quarters are useful because they give you variety and cutting flexibility in a compact format. Whether you are making your first patchwork block or building a coordinated quilt, the important step is to check the actual dimensions and plan your cutting before you begin.
