Single crochet and double crochet are two of the most useful stitches to learn when starting crochet. Both can create attractive, durable fabric, but they produce different results. Single crochet creates a shorter, denser fabric, while double crochet produces taller stitches that build fabric more quickly and often leave more space between stitches.

Choosing between them affects the appearance, flexibility, thickness, and size of your finished project. A stitch that works well for a small amigurumi toy may not be the best choice for a lightweight summer shawl.

This guide explains how single crochet and double crochet differ, how to make each stitch, when to use them, and how to choose the right one for your next project.

What Is Single Crochet?

Single crochet, abbreviated as sc in US crochet terminology, is a short stitch that creates a relatively compact fabric. It is often one of the first stitches beginners learn after making a slip knot and foundation chain.

Because single crochet stitches are short, they usually produce a fabric with fewer visible gaps than taller stitches made with the same yarn and hook.

How to make a single crochet stitch

To practice, begin with a foundation chain of approximately 16 stitches.

1. Insert your hook into the second chain from the hook.

2. Yarn over and pull the yarn through the chain. You should have two loops on your hook.

3. Yarn over again.

4. Pull the yarn through both loops on the hook.

5. Repeat the process across the row.

Once you reach the end, make the turning chain specified by your pattern, turn your work, and continue with the next row.

The exact turning-chain instruction depends on the pattern, but one chain is commonly used when working single crochet in rows.

What single crochet fabric looks like

Single crochet produces a short, relatively firm stitch structure. The fabric can feel dense and substantial, particularly when worked with a smaller hook or tightly spun yarn.

Its main characteristics include:

• A compact appearance with relatively small gaps.

• Good stitch definition, making it suitable for simple shapes and textured designs.

• More individual stitches needed to reach a given height than with taller stitches.

• A firm fabric that can hold its shape well when the yarn and tension are appropriate.

Single crochet is not automatically stiff or inflexible. Yarn fiber, hook size, and tension all affect the finished fabric. A larger hook and a soft yarn can create a more flexible single crochet fabric than a smaller hook and a tightly worked yarn.

What Is Double Crochet?

Double crochet, abbreviated as dc in US crochet terminology, is taller than single crochet. It creates more height with each stitch, making it useful for projects where you want to build fabric quickly.

Double crochet is commonly used in blankets, scarves, shawls, garments, and decorative patterns.

How to make a double crochet stitch

Begin with a foundation chain long enough for your practice row. Follow the pattern’s instructions for the turning chain, then work through these steps.

1. Yarn over before inserting the hook.

2. Insert the hook into the designated stitch.

3. Yarn over and pull through the stitch. You should now have three loops on your hook.

4. Yarn over and pull through the first two loops.

5. Yarn over again and pull through the remaining two loops.

You have completed one double crochet stitch.

The key difference is the extra yarn over at the beginning and the two-stage process used to finish the stitch.

What double crochet fabric looks like

Double crochet creates taller stitches and often produces a more open fabric than single crochet when both are worked with comparable yarn and hook sizes.

Its main characteristics include:

• More height per stitch.

• Faster progress across rows and toward the desired project length.

• A texture with more visible spaces between stitches.

• A lighter, more open appearance in many patterns.

Double crochet is especially useful when you want a fabric with movement or drape. However, closely worked double crochet can still produce a fairly substantial fabric, so the result depends on more than stitch choice alone.

Single Crochet vs. Double Crochet: Key Differences

The most important difference is stitch height, but that difference influences several other aspects of a project.

These are general tendencies rather than strict rules. A tightly worked double crochet fabric may be denser than a loosely worked single crochet fabric, especially if different hook sizes or yarns are used.

Which Stitch Uses More Yarn?

Yarn consumption is not determined by stitch height alone. It depends on the stitch structure, hook size, yarn thickness, tension, and the dimensions of the finished fabric.

For comparable projects made with the same yarn and similar tension, double crochet often creates more height per stitch, but it also uses extra yarn to form the taller stitch. Single crochet uses less yarn per individual stitch, yet more rows or stitches may be required to cover the same area.

As a result, you should not assume that one stitch will always use less yarn for an entire project.

How to compare yarn usage accurately

If you are deciding which stitch to use for a blanket or other large item, make two small swatches:

1. Use the same yarn and hook for both samples.

2. Work one swatch in single crochet and another in double crochet.

3. Make both samples the same width and height.

4. Weigh each sample with a sufficiently precise scale, if available.

5. Compare the weight and fabric characteristics.

This gives you a more useful estimate for your own tension and materials than relying on a general rule.

The swatches also reveal differences in drape, thickness, and gaps, helping you decide which fabric suits the project.

When to Use Single Crochet

Single crochet is useful when you want compact stitches, clear edges, or a fabric that can hold a shape without relying on a complex stitch pattern.

Amigurumi and stuffed toys

Single crochet is widely used for amigurumi, the craft of making small stuffed figures, animals, and decorative objects.

Its relatively compact structure helps reduce the size of gaps through which stuffing might become visible. Many amigurumi patterns also use increases and decreases in single crochet to create rounded shapes.

However, stitch choice alone does not guarantee that stuffing will stay inside. Tension, hook size, and yarn thickness matter as well.

Bags and small accessories

Single crochet can work well for pouches, small bags, baskets, and other accessories that benefit from a compact fabric.

If the finished item needs to support weight, consider the yarn fiber and whether a lining or reinforced handles are necessary. Crochet fabric can stretch under load, even when made with single crochet.

Dishcloths and practical household items

Single crochet can create a useful, closely worked surface for dishcloths and similar projects.

Cotton yarn is often suitable for washable household items because it absorbs moisture and can tolerate repeated use when cared for correctly. Always check the yarn’s washing instructions.

Projects with simple shaping

Single crochet is also useful for squares, rectangular panels, and pieces where you need to control the width and height carefully.

Because the stitch is short, small changes in stitch count can make a noticeable difference in the shape. Counting stitches regularly helps keep the edges straight.

When to Use Double Crochet

Double crochet is a useful choice when you want to create height quickly or make fabric with a more open appearance.

Blankets and throws

Double crochet is popular for blankets because each stitch contributes more height than a single crochet stitch. This can help a blanket grow more quickly.

It also works well with repeated color changes, simple stripes, and decorative stitch patterns.

If you want a warm blanket with fewer gaps, consider a denser stitch pattern or combine double crochet with other stitches to create a more compact fabric.

Scarves and shawls

Double crochet often works well for scarves and shawls because its taller stitches can create a flexible fabric with attractive drape.

The result depends on the yarn. A soft yarn and a suitable hook can produce a flowing fabric, while a stiff yarn or tight tension may make it less flexible.

For a lightweight shawl, you can also combine double crochet with chain spaces to create an open lace pattern.

Garments and wearable accessories

Double crochet is useful for cardigans, loose tops, cover-ups, and other garments where drape and stitch height matter.

However, garments require attention to gauge. If your double crochet stitches are larger than the pattern expects, the finished garment may be wider or longer than intended.

Make a gauge swatch before beginning a fitted project and adjust your hook size if necessary.

Projects that need faster visual progress

If you are new to crochet and want to see a project grow quickly, double crochet can be satisfying because each row usually adds more height.

That does not necessarily mean the whole project will take less time. Taller stitches may require more complex movements, and the pattern may use additional shaping or finishing techniques.

Can You Combine Single Crochet and Double Crochet?

Yes. Many crochet patterns use both stitches to create contrast in height, texture, and density.

Alternating single crochet and double crochet can create a textured fabric, while placing double crochet stitches into selected rows can produce raised patterns or decorative stripes.

For example, a simple practice swatch might alternate one row of single crochet with one row of double crochet. This helps you compare the two stitch heights directly.

However, when combining stitches, pay attention to the stitch count and row height. Because double crochet is taller, alternating rows can produce a fabric with visible ridges or uneven-looking edges if the pattern is not designed for that effect.

A well-written pattern will specify which stitches to use and how to handle turning chains.

Common Mistakes When Learning These Stitches

Beginners often make similar mistakes when switching between single crochet and double crochet.

Confusing US and UK terminology

In US crochet terminology, single crochet is abbreviated sc and double crochet is dc. In UK terminology, the same stitch names refer to different stitch structures.

A US single crochet is called a UK double crochet, while a US double crochet is called a UK treble crochet.

Always check whether a pattern uses US or UK terminology before starting.

Making double crochet too tight

Double crochet requires multiple yarn-over and pull-through movements. Pulling the loops too tightly can make the hook difficult to move and produce stiff fabric.

Allow the loops to sit comfortably on the hook shaft and maintain a relaxed grip.

Skipping the first or last stitch

This mistake often causes a rectangular project to become narrower with each row.

Before starting a new row, identify the first actual stitch and confirm where the final stitch belongs. Use stitch markers at the edges if necessary.

Using the wrong hook size

A hook that is too small for your yarn and tension may make the fabric tighter than intended. A much larger hook may create loose stitches and unwanted gaps.

Check the yarn label and pattern recommendations, then test the result with a swatch.

How to Choose the Right Stitch for Your Project

The best stitch depends on the result you want rather than which stitch is easier or more popular.

Use single crochet when you want:

• A compact fabric for stuffed toys or small accessories.

• Clear stitch definition for simple shapes.

• A sturdy-looking surface with relatively small gaps.

• More control over detailed shaping in many beginner patterns.

Use double crochet when you want:

• Faster progress in fabric height.

• A flexible fabric for scarves and shawls.

• A more open appearance.

• A stitch that works well in blankets, garments, and decorative patterns.

If you are uncertain, make two small swatches using the same yarn. Compare their appearance, flexibility, and stitch definition. This simple test can prevent you from spending hours on a project that does not produce the texture you expected.

Conclusion

Single crochet and double crochet are foundational crochet stitches, but they serve different purposes. Single crochet creates shorter stitches and often produces a compact fabric suited to amigurumi, small accessories, and household items. Double crochet creates taller stitches, builds fabric height more quickly, and is commonly used for blankets, scarves, shawls, and garments.

Neither stitch is universally better. Your choice should depend on the project’s intended shape, texture, flexibility, and appearance, as well as the yarn and hook you plan to use.

Learn both techniques, practice them with the same materials, and compare the results. Once you understand how each stitch changes the fabric, choosing the right one for future crochet projects becomes much easier.
