Dimensions Of A Fat Quarter – And Other Pre Cut Fabric Sizes!

Looking for the dimensions of a fat quarter? Fat quarters are a square shape of fabric sold at quilt shops the world over, and I myself have even purchased fat quarter bundles as a way of adding cut pieces of cotton fabric to my stash without having to buy a quarter yard of fabric for every fabric design that I like.

Usually when we buy fabrics, the absolute minimum purchase amount of a piece of fabric is 10″ / 25cm, though many shops and online fabric stores insist on a minimum of 20″ / 50cm.

This can then be an expensive way to build your fabric stash – trust me, I did this throughout my time at fashion school when I had to supply fabric swatches as part of my design process.

When a fabric store couldn’t guarantee that they’d have the fabric in stock 2 months later, I’d often have to buy more than an entire yard of fabric to make sure that I had a big enough amount of fabric to use in a design if my tutors insisted upon it.

How Many Fat Quarters In A Yard Of Fabric?

There are four fat quarters in a yard of fabric. With one yard of fabric being cut from the bolt, it is then cut in half width-wise and length-wise and you’re left with four quarters, commonly called ‘fat quarters’, because they’re not quite square with each quarter being more of a rectangular shape.

You can also buy the above as ready made pre-cut bundles of fabric if you’d rather not cut fabric to size yourself, with Moda fabrics being a firm favourite. These smaller pieces of fabric have different names depending on size and the company creating them, but the ones listed will be easily recognized – even at your local quilt shop!

Charm Packs

Charm packs contain charm squares which are 5″ x 5″ / 12.5cm x 12.5cm. Size wise these come out smaller than a layer cake piece of fabric but bigger than a mini charm pack piece.

Charm packs contain around 42 squares, and are great for smaller projects, like baby quilts, bags, purses and English paper piecing.

English paper piecing works well with fat quarter fabric bundles!

Fat Eighths

A fat eighth is a single fat quarter cut in half widthways, and measures 9″ x 22″ / 22.5cm x 55cm. From a fat eighth you can cut charm packs and mini charm packs for yourself.

Jelly Rolls

Jelly roll strips are are 2.5″ / 7.5cm wide with their length being determined by the width of the bolt of fabric. Because of the continuous length of these strips, they’re a much better format for using on borders, creating binding, easy quilted placemats and more.

Layer Cakes

You can cut a fat quarter into smaller squares at 10″ x 10″ / 25cm x 25cm to create a layer cake. Layer cakes are great for creating small quilts or pillows as they usually come with a selection of fabric squares that are color co-ordinated.

They also work well to cut into smaller squares.

Mini Charm Packs

These mini charms are smaller than the charm packs created by Moda fabrics. Dimensions for each fabric piece are 2.5″ x 2.5″ / 6.25cm x 6.25cm. They’re great for making a small lap quilt if you’re a beginner quilter, coming with around 42 small squares of fabric

So there you have it. Fat quarters are the perfect way to get your hands on a wide assortment of quilting fabrics without having to buy whole cuts of different types of fabric making it a more popular and less costly way to increase your available fabric stash for future projects.

For my next project I quite like the idea of sewing together jelly roll strips from multiple packs and then cutting them into a biker style jacket. I think it could be quite a fun and unique look, don’t you? I just need to work out how much fabric I’ll need for it!
