Why Crochet a Phone Case?
Before diving into the pattern itself, it is worth appreciating why this project is worth your time. Most store-bought phone cases are made from plastic or silicone. They protect the phone from drops, sure, but they do not have much personality. A crocheted phone case, on the other hand, is soft, stretchy, and completely unique. You choose the colors. You choose the texture. You can add buttons, flowers, fringe, stripes, or even a tiny cactus. No two will ever be exactly alike.
Crocheted cases also make excellent gifts. They are quick to work up — most makers finish one in an evening or two — so you can make several for friends and family without spending a fortune on supplies. They are also a wonderful stash buster if you have leftover yarn from other projects sitting in a basket somewhere.
Beyond the aesthetics, a crocheted case provides a surprising amount of padding. The layers of yarn create cushion around the phone that can absorb minor bumps and scratches. They also absorb sweat and oil far better than plastic, meaning your phone stays cleaner in your pocket or bag.
Materials You Will Need
One of the best things about this pattern is how little you need to get started. Here is the full supply list.
Yarn: Approximately 50 to 80 yards of worsted weight yarn (Category 4). Cotton yarn works beautifully for this project because it is sturdy, washable, and has a clean stitch definition. Acrylic yarn is also a great choice, especially if you want more color options or a softer feel. If you want extra durability, look for a cotton-acrylic blend.
Hook: A 4.0 mm or 4.5 mm crochet hook. The size depends on your gauge and how tightly you naturally crochet. A slightly smaller hook creates a denser fabric that protects the phone better.
Notions: A yarn needle for weaving in ends, scissors, a button or snap closure (optional), stitch markers (optional but helpful), and a ruler or tape measure.
Your phone: Keep it nearby to check the fit as you go. This pattern is worked to fit most standard smartphones, but the beauty of crochet is how easy it is to adjust on the fly.
Understanding Gauge
Gauge matters more for a phone case than it might for a blanket or a scarf, because the fit needs to be snug enough to keep the phone from sliding out but not so tight that getting the phone in and out becomes a wrestling match. The goal is a slightly stretchy case that hugs the phone gently.
For this pattern, aim for approximately 16 single crochet stitches and 18 rows equal to a 4-inch by 4-inch square using worsted weight yarn and a 4.0 mm hook. If your swatch comes out larger, go down a hook size. If it comes out smaller, go up a hook size. Do not skip the gauge check — it takes only a few minutes and saves you from finishing a case that does not fit.
Abbreviations and Stitch Guide
This pattern uses simple stitches that are perfect for beginners while still producing a beautiful, professional-looking result.
ch — chain stitch
sl st — slip stitch
sc — single crochet
sc2tog — single crochet two together (decrease)
st — stitch
sp — space
RS — right side
WS — wrong side
If you are new to crochet, the single crochet is your best friend. It creates a tight, sturdy fabric that holds its shape well — exactly what you want for a phone case. Every stitch in this pattern is either a chain, a single crochet, or a slip stitch to join rounds.
Pattern Notes
This case is worked in the round from the bottom up. You begin with a foundation chain, join it into a loop, and then work continuous rounds up to the opening. The construction means there is no seaming required, which keeps the project tidy and fast.
The pattern is written for a phone measuring approximately 6 inches tall and 3 inches wide, which fits most modern smartphones including iPhone 14 and 15 series, Samsung Galaxy S series, and similar models. Sizing adjustments are explained in detail after the main pattern so you can customize it for any phone.
Free Crochet Phone Case Pattern
Step 1: Create the Foundation
Begin by chaining 21. This creates the foundation for the bottom of the case.
Row 1: Starting in the second chain from the hook, sc in each chain across. You will have 20 sc. Do not turn.
Rather than turning your work, you are going to continue working around the foundation chain so that you can crochet the other side. This creates a seamless bottom for the case.
Continue working 3 sc in the last stitch (this rounds the bottom corner), then work 20 sc back along the opposite side of the foundation chain, and then 3 sc in the first stitch (this rounds the other bottom corner). You should now have a total of 46 stitches in your first round.
Place a stitch marker in the first stitch of the round to mark your starting point. This helps you keep track of rounds as you go.
Step 2: Work the Body
From this point forward, you will work in continuous rounds without joining or turning, unless a design option specifies otherwise. Move your stitch marker up at the beginning of each new round.
Rounds 2 through 30: Sc in each st around. (46 stitches per round)
This creates the main body of the case. As you work, stop occasionally to slide your phone in and check the height. If your phone is taller than average, you may need to work a few extra rounds before moving on. The goal is to have the phone sitting comfortably in the case with about half an inch to three-quarters of an inch of case extending above the top of the phone.
Step 3: Create the Top Opening
Once the body is the correct height, you have two options for finishing the top: an open edge with a clean border, or a flap closure that folds over to keep the phone secure. Both options are described below.
Option A — Open Top with Slip Stitch Border
Round 31: Sl st in each st around. Join with a sl st to the first sl st to close the round. Fasten off and weave in ends.
This gives you a clean, neat edge at the top of the case. It is the simplest finish and works beautifully if you plan to add a button-and-loop closure on the side.
Option B — Flap Closure
Instead of working in the round, you will now work back and forth in rows to create a flap that folds over the front of the phone.
Row 31: Sc across the front 20 stitches only. Turn. (20 stitches)
Row 32: Ch 1, sc in each st across. Turn.
Row 33: Ch 1, sc in each st across. Turn.
Row 34: Ch 1, sc2tog, sc in each st across to last 2 sts, sc2tog. Turn. (18 stitches)
Row 35: Ch 1, sc in each st across. Turn.
Row 36: Ch 1, sc2tog, sc in each st across to last 2 sts, sc2tog. Turn. (16 stitches)
Row 37: Ch 1, sc in each st across. Fasten off, leaving a long tail.
Work a row of sc evenly around the entire flap edge for a tidy border. Add a button on the front body of the case and a corresponding chain loop at the tip of the flap for a secure closure.
How to Adjust the Size
Crochet stretches, which means this pattern accommodates a range of phone sizes. However, if you want a perfect fit, here is how to calculate adjustments.
Width: Measure your phone’s width in inches and multiply by the stitch gauge (4 stitches per inch for most worsted weight yarn on a 4.0 mm hook). Add two stitches for ease. This gives you your foundation chain number. For example, a phone that is 3.5 inches wide needs approximately 16 stitches plus 2 for ease, so a foundation chain of 19.
Height: Measure your phone’s height and add about half an inch for the ease of getting the phone in and out. Use this measurement to determine how many rounds to work in Step 2. At approximately 4.5 rows per inch with worsted weight yarn, a 6.5-inch phone needs approximately 30 rounds.
Thickness: If your phone is particularly thick, the stretchy nature of single crochet usually accommodates it, but you can work a slightly wider foundation chain to be safe.
Customization Ideas
One of the most exciting parts of making your own phone case is personalizing it. Here are some ideas to inspire you.
Stripes: Switch yarn colors every two rounds to create a simple stripe pattern. Carry the unused color up the inside of the work to avoid too many ends to weave in.
Bobble stitches: Work a bobble stitch in the center of every fourth round on the front panel to add dimension and texture.
Surface crochet: Once the case is finished, use a contrasting yarn to work surface crochet chains in any shape you like — flowers, hearts, initials, or geometric patterns.
Embroidery: Use a yarn needle and contrasting thread to embroider small designs on the finished case. Simple cross-stitches or running stitches look beautiful on the flat surface that single crochet creates.
Wrist strap: Cut a length of sturdy yarn or ribbon and thread it through one side of the case near the opening to create a wrist loop. This keeps your phone handy during walks or outdoor activities.
Pocket: Before beginning Round 31 of the main pattern, crochet a small flat rectangle and slip stitch it to the back of the case to create a card pocket. This is especially useful for holding a credit card or transit pass.
Finishing Your Case
Finishing is what takes a project from handmade to beautifully handcrafted. Take your time with this step.
When you fasten off, leave a 6-inch tail. Thread this tail onto your yarn needle and weave it in and out through the back bumps of the nearby stitches for about an inch in one direction, then turn and weave back for another inch in the opposite direction. Pull gently and snip close to the work. A properly woven end will never unravel, no matter how much the case stretches.
If you used multiple colors, weave in each color change end on the wrong side of the work, following the path of the same-colored yarn as much as possible for a truly invisible finish.
Block your finished case if you want the stitches to even out and the overall shape to look crisper. For cotton yarn, wet blocking works beautifully. Simply soak the case in cool water, gently squeeze out the excess moisture without wringing, then shape it around your phone and lay it flat to dry. The difference in stitch definition before and after blocking is remarkable.
Caring for Your Crochet Phone Case
A phone case picks up a lot of use, so it is helpful to know how to keep it clean. Cotton and acrylic yarns are both machine washable in most cases, but check your yarn’s label to be sure. Wash in a mesh laundry bag on a gentle cycle with cool water. Reshape while damp and allow to dry flat rather than in the dryer, which can cause shrinkage or distortion.
If a quick spot clean is all you need, a damp cloth with a drop of gentle dish soap works well for removing smudges and oils without soaking the whole case.
Tips for Beginners
If this is one of your first crochet projects, welcome to a wonderfully addictive craft. A few tips will make the process smoother.
Keep your tension consistent from stitch to stitch. If some stitches are very tight and others are loose, the case will look uneven. Try to maintain a relaxed, even grip on both the hook and the yarn.
Count your stitches at the end of every few rounds, especially early on. It is much easier to catch a mistake when it is a round or two behind you than when you have worked all the way to the top and notice the case is lopsided.
Use a stitch marker. This little tool costs almost nothing and prevents so much frustration. You always know where your round begins, which means you will never lose your place.
Do not be afraid to pull back a few rounds if something does not look right. In crochet, this is called “frogging” (because you rip it, rip it — a bit of crafting humor that never gets old). Every experienced crocheter frogs work regularly. It is part of the process, not a sign of failure.
Frequently Asked Questions
Can I use bulky yarn for this pattern? You can, but bulky yarn creates a much thicker fabric that may make the case too stiff and hard to slip the phone into. Worsted weight is the sweet spot for this project.
How long does this project take? Most crocheters finish a basic case in two to four hours. The flap closure option adds another hour or so. It is a wonderful project for a quiet evening or a long car ride.
Can I sell cases made from this free pattern? Yes. This pattern is shared freely for both personal and commercial use. If you sell cases made from this pattern, a credit or link back to this post is always appreciated but not required.
What if my case comes out too big? Try washing it in warm water and drying it in the dryer on low heat (if your yarn allows this). The slight shrinkage may bring it back to the right size. Alternatively, work another case with a smaller hook or fewer foundation stitches.
Can I use this pattern for a tablet sleeve? Absolutely, with size adjustments. For a standard 10-inch tablet, multiply the foundation chain proportionally and add rounds until the height is correct. Use bulky weight yarn and a 6.0 mm hook for a quicker work-up.
A Few Final Thoughts
Making something by hand carries meaning that store-bought items simply cannot match. Every stitch in your crochet phone case was placed there deliberately, with care, by you. That is worth something. When you slide your phone into a case you made yourself, or give one to a friend who lights up when they see it, you are reminded that craft is not just a hobby — it is a way of connecting with both the making of things and the people who receive them.
This free pattern is here for you to use as many times as you like, to modify, to share, and to make your own. Experiment with colors. Try new stitches. Add that embroidered flower you have been thinking about. There is no wrong direction as long as you enjoy the process.
Happy crocheting — and may your yarn never tangle.
