How to Crochet a Simple Phone Case – Free Beginner Pattern
If you’ve been wanting to try crochet but aren’t sure where to start, making a phone case is one of the most satisfying beginner projects you can pick up. It’s small enough to finish in an afternoon, practical enough to use every day, and forgiving enough that even your first attempt will turn out looking great. This free beginner pattern walks you through everything you need to know, from the materials you’ll gather to the final finishing touches, with clear instructions at every step.
Whether you’re brand new to crochet or you’ve done a little bit before and want to build your confidence, this project is the perfect place to start. By the time you’re done, you’ll have a cozy, custom phone case that fits snugly around your device and shows off your new skill to everyone who sees it.
What You’ll Need Before You Start
One of the best things about this project is that the supply list is short and inexpensive. You probably won’t need to spend more than a few dollars to get everything together, and many of these items may already be sitting in your home.
Yarn: Choose a medium weight yarn, also called worsted weight or size 4. Cotton yarn works especially well for phone cases because it has very little stretch, which means your case will hold its shape nicely. Acrylic yarn also works and gives you an enormous range of colors to choose from. You’ll need only a small amount — roughly 50 to 75 yards — so this is a great project for using up leftover yarn from other projects.
Crochet Hook: A 4.0 mm or 4.5 mm hook pairs well with worsted weight yarn. If you’re using a thicker yarn or your tension tends to run a little loose, go down to a 3.75 mm hook to keep your stitches tight enough that the phone won’t slip out.
Scissors: Any pair of scissors will do. You’ll use them to cut the yarn at the end of the project.
Tapestry Needle: Also called a yarn needle or darning needle, this blunt-tipped needle is how you’ll weave in your loose yarn ends when the project is finished. It’s a small but essential tool, and a pack of them usually costs less than a dollar.
Stitch Markers: Optional but helpful, especially for beginners. Placing a stitch marker at the beginning of each round helps you keep track of where one round ends and the next begins.
Your Phone: Keep your phone nearby as you work. Because phone sizes vary quite a bit from model to model, you’ll be checking the fit as you go rather than following rigid dimensions.
Understanding the Stitches You’ll Use
This pattern uses only two basic crochet stitches: the chain stitch and the single crochet stitch. If you’ve never crocheted before, spend five or ten minutes practicing these stitches on a small swatch before you begin the actual phone case. Getting comfortable with how the yarn moves around your hook will make the whole project feel much smoother.
Chain Stitch (ch): The chain stitch is how almost every crochet project begins. Start with a slip knot on your hook, then wrap the yarn over the hook and pull it through the loop already on your hook. That makes one chain. Repeat this motion for as many chains as the pattern calls for. Chain stitches look like a little braid and form the foundation row of your work.
Single Crochet (sc): The single crochet is the shortest and simplest of the main crochet stitches, and it creates a tight, dense fabric — perfect for a phone case because it gives your work structure and doesn’t have gaps that could snag on things in your bag. To make a single crochet, insert your hook into the stitch, wrap the yarn over the hook and pull up a loop (you now have two loops on your hook), then wrap the yarn over the hook again and pull through both loops. That’s one single crochet complete.
Slip Stitch (sl st): You’ll use the slip stitch to join rounds when working in the round. To make a slip stitch, insert your hook into the stitch, wrap the yarn over, and pull through both the stitch and the loop on your hook in one motion. It creates almost no height and is mainly used to join, move across stitches, or create a flat seam.
Gauge and Sizing
Gauge in crochet refers to how many stitches and rows fit into a specific measurement, usually a four-inch square. For a project like this, gauge matters more than it would for something like a blanket, because you want the case to fit your phone properly rather than being too loose or too tight.
Before you start the main project, crochet a small test swatch of about 15 single crochets across and 10 rows high. Measure it with a ruler and see how your stitches compare. If your swatch is larger than expected, try a smaller hook. If it’s smaller, try a larger hook.
That said, because this pattern has you check the fit against your actual phone as you go, you have quite a bit of flexibility. The pattern is designed to be adjusted easily, and the instructions will tell you exactly when and how to check whether your sizing is on track.

Step 1 — Create Your Foundation Chain
Measure the width of your phone. Most standard smartphones are between 2.5 and 3.5 inches wide. You’ll want your foundation chain to be approximately equal to the width of your phone, or just a tiny bit narrower, since the fabric will stretch slightly to accommodate the phone.
Chain 16 stitches if your phone is on the narrower side (around 2.5 to 2.75 inches wide). Chain 18 stitches if your phone is average width (around 2.75 to 3 inches wide). Chain 20 stitches if your phone is wider (around 3 to 3.5 inches wide).
These are starting points. After you complete your first few rows, you’ll hold the piece up to your phone and adjust if needed.
Step 2 — Work the First Row
Turn your chain so the bottom of each chain stitch is facing up. Insert your hook into the second chain from the hook (skipping the very first chain, which acts as a turning chain). Single crochet across the entire row.
At the end of the row, you should have 15, 17, or 19 single crochet stitches depending on which starting chain count you chose. The final stitch count should always be one less than your original chain, because that first skipped chain doesn’t count.
Chain 1, then turn your work. This chain 1 at the end of each row is your turning chain, and you’ll do this every time you reach the end of a row throughout the entire project.
Step 3 — Continue Rows Until the Case Reaches the Right Length
Single crochet across each row, chaining 1 and turning at the end of every row. Keep working back and forth in rows until the piece is long enough to fold in half and cover your phone with about half an inch to spare above the top edge.
Most phones are between 5.5 and 6.5 inches tall. This means you’ll want your crocheted rectangle to be approximately 12 to 14 inches long before folding. Check frequently by folding the piece and holding it against your phone. You want the fold to sit snugly at the bottom of the phone, with enough fabric on each side to cover the phone and meet at the top.
Work slowly and check often. It’s much easier to add a few more rows than to unravel rows you’ve already done.
Step 4 — Fold and Join the Sides
Once your rectangle is the right length, fold it in half with the right side (the side that looks cleaner and more textured) facing outward. The two short edges of your rectangle should line up at the top, and the fold becomes the bottom of your phone case.
Now you’ll join the two long sides together to create the pocket that your phone will slide into. There are two ways to do this.
The first option is to use a slip stitch seam directly on your hook. With the folded piece held together, insert your hook through both layers at once at the corner where the fold meets the long edge. Join your yarn here with a slip stitch, then single crochet through both layers all the way up the side edge to the open top. Fasten off, then repeat on the other side.
The second option is to use your tapestry needle and a length of yarn to whipstitch the two sides together. Thread about 18 inches of yarn onto the needle, align both layers carefully, and sew through the edge stitches in a simple over-and-over motion. This method gives you a flatter seam and can be easier for absolute beginners who find working through two layers on a hook a little tricky.
Either method works well. The slip stitch method is faster; the whipstitch gives a neater result on the inside.
Step 5 — Add a Border Around the Opening (Optional but Recommended)
To give the top opening of your phone case a clean, finished edge, work a single row of single crochet all the way around the opening. Join your yarn at one of the seam corners at the top, chain 1, then single crochet evenly across the front, around the corner, across the back, and around the other corner to return to where you started. Join with a slip stitch to your first single crochet. Fasten off.
This step also reinforces the top of the case and helps it keep its shape over time.
Step 6 — Weave In Your Ends
Thread the loose yarn tails onto your tapestry needle one at a time. Weave each tail back and forth through several stitches on the wrong side of the fabric in different directions so it’s securely anchored and won’t unravel with use. Trim any excess yarn close to the fabric surface.
Step 7 — Check the Fit and Slide Your Phone In
Slide your phone into the finished case and check the fit. It should feel snug but not so tight that you’re forcing the phone in. The phone should be fully covered with the opening sitting just at or a little above the top edge of the phone.
If the case is a little loose, you can work a row of single crochet along each side seam to tighten things up, or simply keep the measurement in mind for the next time you make one. If it’s too tight, that’s less easy to fix, which is why checking the fit frequently during Step 3 is so important.
How to Add a Button Closure
If you want your phone case to have a closure at the top to keep the phone from slipping out, a simple button loop is an easy and charming addition. You don’t even need to know any new stitches to make it.
After you’ve worked the border row around the opening, find the center of the front edge. Count your stitches and mark the middle. In that center position, chain 6 instead of making a single crochet, then skip the same number of stitches and continue single crocheting to the end. This creates a small chain loop that will serve as your button loop.
On the back of the case, sew a button in the corresponding position using your tapestry needle and a short length of yarn. Slide the phone in, fold the front flap down, and loop the button through the chain. Done!
You can use any button you like — a wooden button gives a natural, rustic look, a pearlescent white button looks clean and classic, and a novelty button in a fun shape makes the case feel more personal. A button between half an inch and three-quarters of an inch in diameter tends to work best for this size of loop.
Ideas for Customizing Your Phone Case
Once you’ve made one phone case following the basic pattern, the real fun begins. Here are some ideas for making future versions even more unique.
Stripes: When you start a new row, switch to a different color of yarn instead of continuing with the same one. Carry the unused color up the side of your work or cut and rejoin as you prefer. Even a single stripe of contrasting color makes a big visual impact.
Textured stitches: Swap the single crochet for a half double crochet stitch once you’re comfortable with the pattern. Half double crochet creates a slightly taller stitch with a softer feel and a subtle ridge that adds texture.
Embroidery: After the case is finished, use a tapestry needle and contrasting yarn to embroider simple shapes onto the front — flowers, stars, initials, or geometric patterns. Crocheted fabric makes a wonderful embroidery ground.
Fringe: Cut several lengths of yarn about four inches long, fold each in half, and use your hook to pull the folded loop through the bottom edge of the case, then pull the tails through the loop and snug it down. Repeat along the whole bottom edge for a fun boho fringe detail.
Pockets: Work a small additional rectangle in a contrasting color and slip stitch it onto the front of the finished case to create a card pocket. Ideal for keeping an ID or transit card with your phone.
Beginner Tips for a Better Result
If this is your first crochet project, a few extra tips can make a noticeable difference in how your finished case looks and feels.
Keep your tension consistent. Tension means how tightly or loosely you hold the yarn as you work. Inconsistent tension leads to stitches that vary in size, giving your fabric an uneven appearance. Try to hold the yarn with the same amount of resistance throughout the project. This takes practice, and it’s completely normal for tension to vary when you’re just starting out.
Count your stitches at the end of every row. It’s easy to accidentally add or skip a stitch, especially when you’re getting comfortable with the motion. Counting takes only a few seconds and saves you from discovering a mistake ten rows later.
Don’t rush the turning chain. That chain 1 you make before turning at the end of each row is easy to forget or to mistake for a real stitch. Remind yourself each time: chain 1, turn, then start your single crochets in the first actual stitch, not in the chain itself.
Work in a good light. Crochet stitches can be surprisingly hard to see in dim light, especially with dark yarn colors. If possible, work near a window or under a bright lamp. If you’re a beginner, lighter yarn colors are also much easier to work with because you can see each stitch clearly.
Be patient with yourself. Crochet has a small learning curve, and your first few rows might look messier than you’d like. Keep going anyway. Stitches almost always even out and improve as you get into the rhythm of a project, and by the time you’ve finished the phone case, your work from row ten onward will look significantly more polished than row one.
Making This Pattern as a Gift
A crocheted phone case makes a wonderful handmade gift, and because the project works up so quickly, you can make several in an evening. Before you start, ask the recipient what phone they use — or measure the case against a phone of the same model at a shop — so you can size the case correctly. Choosing yarn in their favorite colors or a yarn with a subtle sparkle or special texture makes the gift feel extra thoughtful.
Pair the finished case with a small card explaining that it’s handmade, and include the washing instructions for the yarn you used. Most cotton and acrylic yarns are machine washable on a gentle cycle, which makes the gift practical for everyday use.
Taking Care of Your Crochet Phone Case
To keep your case looking its best, shake it out or brush off any lint or debris regularly. If it needs washing, check the yarn label for specific instructions. Most worsted weight cotton and acrylic yarns can be hand washed in cool water with a small amount of gentle dish soap or hand soap. Rinse well, squeeze out the excess water gently without wringing, and lay the case flat to dry. Avoid putting it in a tumble dryer on high heat, as this can cause the fibers to shrink or pill.
With minimal care, a well-made crocheted phone case will last for years and age beautifully as the yarn softens with use.
What to Make Next
Now that you’ve completed your first crochet project, you’ve learned the foundational skills that most crochet patterns are built on. The chain stitch, single crochet, and slip stitch appear in hundreds of patterns ranging from dishcloths and coasters to bags, hats, and garments. A phone case is an ideal starting point because it teaches you how to work in rows, check fit as you go, and finish a piece neatly — all skills that transfer directly to bigger projects.
From here, you might want to try a simple market bag using the same single crochet fabric in a slightly larger version, a set of washcloths using the same stitch but a longer foundation chain, or a bookmark that uses just a single chain with a small
