Knitted Phone Case Pattern: Make ALL The Things

There is something deeply satisfying about knitting a practical object. Scarves and hats are wonderful, but when you finish a project and slide your phone into a perfectly fitted knitted case you made yourself, it hits different. This pattern is designed to be approachable for beginners while still giving experienced knitters a satisfying quick make. Whether you want to use up scrap yarn, try a new stitch pattern, or simply protect your phone in the coziest way possible, this knitted phone case is the project for you.

Let’s get into everything you need to know — materials, gauge, stitch patterns, the full pattern itself, and plenty of tips along the way.

Why Knit a Phone Case?

Before we dive into the yarn and needles, let’s talk about why a knitted phone case deserves a spot in your project queue.

For starters, it’s fast. Depending on your knitting speed, you can finish this project in a single evening or over a lazy weekend morning with a good cup of coffee. It’s an excellent project for those moments when you want to knit but don’t have the mental bandwidth for a complicated lace shawl or a fitted sweater with seventeen pieces.

A knitted phone case also makes a fantastic gift. Who doesn’t appreciate something handmade and practical? You can customize the colors and stitch pattern for the recipient — a bold geometric look for your artsy friend, something soft and neutral for your minimalist sister, or a chunky textured case for anyone who loves the cozy aesthetic.

Finally, it’s a stash buster. This pattern uses a very small amount of yarn, which means it’s the perfect excuse to finally dig into those single skeins and leftover balls you’ve been hoarding for years. No judgment here — we all have them.

Materials You’ll Need

Keeping the materials list short and manageable is part of what makes this pattern so appealing.

Yarn: Approximately 50–80 yards of worsted weight yarn (Category 4). Any fiber works here — wool, cotton, acrylic, or a blend. That said, a yarn with some elasticity (like a wool or wool blend) will give the case a snug, fitted feel, while cotton will create a firmer, slightly stiffer structure. Both are great; it just depends on your preference.

Needles: US Size 6 (4.0 mm) double-pointed needles or a short circular needle if you prefer knitting in the round. You can also work this flat on straight needles and seam the sides — instructions for both methods are included below.

Other supplies: A tapestry needle for weaving in ends, scissors, a button or a snap closure (optional but recommended), and a stitch marker if you’re knitting in the round.

Gauge: 20 stitches and 28 rows = 4 inches in stockinette stitch with US Size 6 needles. Gauge is more important than you might think for this project because a phone case needs to fit well. Too loose and your phone will slip out; too tight and it won’t go in comfortably. Take ten minutes to knit a swatch — your future self will thank you.

Sizing and Measurements

Phone sizes vary enormously, so this pattern is written to be easily adjusted. Before you cast on, measure your phone.

For most standard smartphones (roughly 6 inches tall and 3 inches wide), the base pattern measurements are:

Width: approximately 3.5 inches wide (to allow for a snug but comfortable fit)
Height: approximately 6.5 inches tall (enough to fully cover the phone with a small flap)

If you have a larger phone — a Plus or Pro Max model, for example — simply increase the stitch count by 4–6 stitches and add an extra half inch to your height. If you have a smaller phone, decrease by 4 stitches and subtract a quarter inch from the height. The math is forgiving here.

Stitch Patterns to Choose From

One of the joys of this project is how versatile it is in terms of texture and stitch work. The pattern below is written in stockinette, but here are some beautiful alternatives that work just as well and add wonderful visual interest.

Seed stitch creates a beautiful, bumpy texture and lies completely flat without curling, which makes it ideal for a phone case. It also looks polished and a little rustic at the same time. Work it by alternating knit and purl stitches across every row, then on the following row, knit the purls and purl the knits.

Ribbing (1×1 or 2×2) gives the case a stretchy, fitted quality that really hugs your phone and keeps it secure. It also adds a lovely textured stripe effect. This is an especially great choice if your yarn has minimal elasticity.

Garter stitch is the simplest option and the most forgiving for new knitters. Knit every row, and you’ll end up with a ridged, squishy fabric that’s thick enough to provide a bit of cushion — an added bonus for phone protection.

Simple cable panel adds a wow factor that makes this small project look like it took far more skill than it did. A simple 6-stitch cable panel down the center of the case is striking and impressive, and the rest of the work is all stockinette.

The Pattern: Knitted Phone Case

Cast On

Using your US Size 6 needles and your chosen yarn, cast on 34 stitches. If you’re knitting in the round, distribute these stitches across three or four double-pointed needles and join to work in the round, being careful not to twist.

If you’re working flat, cast on 34 stitches on straight needles.

Foundation Rows

Work 4 rows (or rounds) in 1×1 rib (knit 1, purl 1 across) to create a firm, stable base. This prevents the bottom edge from rolling and gives the case a clean, finished look from the start.

Main Body

If knitting flat:
Row 1 (RS): Knit across.
Row 2 (WS): Purl across.

Repeat rows 1 and 2 (stockinette stitch) until your piece measures 5.5 inches from the cast-on edge, ending with a wrong side row.

If knitting in the round:
Knit every round (this creates stockinette in the round). Continue until your piece measures 5.5 inches from the cast-on edge.

At this point, you have two options for finishing the case: a simple top flap, or a closed top that you graft shut. Both options are detailed below. The flap version is more beginner-friendly and allows for easier access to your phone.

Option A: Top Flap

Continue knitting back and forth in stockinette (even if you’ve been working in the round — at this point, switch to flat knitting). Work the flap on only the front 17 stitches. Place the remaining 17 stitches on a holder or a length of scrap yarn.

Flap rows:
Row 1 (RS): Knit across (17 stitches).
Row 2 (WS): Purl across.

Repeat these two rows until the flap measures 2 inches from where you began it.

Buttonhole row: Knit 7, bind off 3 stitches, knit to end (7 stitches remain after the gap).
Next row: Purl 7, cast on 3 stitches using the backward loop method over the gap, purl 7.

Continue in stockinette for 3 more rows, then bind off all stitches. For the back of the case, rejoin yarn to the held 17 stitches and bind off across the row.

Option B: Closed Top (Grafted)

If you’ve been working in the round, you’ll have a tube at this point. Divide the stitches evenly — 17 on one needle at the front, 17 on one needle at the back. Use the Kitchener stitch to graft the two sets of stitches together, creating a seamless, closed top.

If grafting feels intimidating, you can also simply bind off all stitches and then seam the top closed using a mattress stitch or whipstitch with your tapestry needle. The grafted version looks more polished, but both work equally well.

Finishing the Case

If you knitted flat, fold the piece in half lengthwise with right sides facing out and seam the two side edges together using mattress stitch. Work from the bottom up, keeping your seam tight and consistent for a clean edge.

Weave in all ends securely using your tapestry needle. If you made the flap version, sew a button to the front of the case, centered, at a position that aligns with your buttonhole.

Give your case a gentle block if desired — especially if you used wool. Wet blocking will even out your stitches beautifully and make the finished case look much more professional.

Tips for a Great Result

Check your gauge, seriously. This is a small project, and a small deviation in gauge can mean the difference between a case that fits perfectly and one that’s too loose or too tight to be useful. If your gauge is off, adjust your needle size up or down as needed.

Choose your yarn thoughtfully. For everyday use, a superwash wool or a durable acrylic blend will hold up best. If you’re making this as a gift or a special item, a luxurious merino or cashmere blend feels incredible and looks stunning. Avoid very fuzzy yarns like mohair for this project — they make it hard to see your stitches and can interfere with the phone’s buttons and ports.

Tension matters on the flap. When you switch to working the flap flat after working in the round, your tension can shift. Pay attention to the edges and give them a little extra tension if needed to prevent holes or loose stitches at the join.

Use a snap closure instead of a button. If you’re not confident sewing on a button, or if you want a sleeker look, a simple magnetic snap or a sew-on snap fastener works beautifully. They’re secure, easy to attach, and very clean-looking on a finished case.

Reinforce the bottom seam. Since the bottom of the case takes the most wear, it’s worth going over your bottom seam twice or running a second line of whipstitch along the interior to reinforce it. This is especially true if you’re using a lighter-weight yarn or if the phone will be sliding in and out frequently.

Customization Ideas

The basic pattern above gives you a solid foundation, and from there the possibilities are genuinely endless. Here are some directions you can take it.

Stripes: Carry a second color alongside your main color and switch every two rows for bold, even stripes. You can also carry the unused yarn loosely up the side to avoid too many ends.

Colorwork: A small, simple Fair Isle or stranded colorwork band adds stunning visual interest. Even a single row of patterned motifs — tiny hearts, stars, geometric shapes — can completely transform the look of the case.

Embroidery: Once your case is finished, you can add surface embroidery with a contrasting yarn or embroidery floss. A small floral motif, your initials, or a simple botanical design adds a personal, artisan touch.

Different yarn weights: Want a thicker, chunkier case that provides more protection? Scale up to a bulky weight yarn and use US Size 9 or 10 needles. You’ll need fewer stitches but the fabric will be denser and more protective. Going down to a DK or fingering weight gives you a more delicate, slim-fitting case.

Pocket or card holder: Work a small rectangular patch in a contrasting color and sew three sides to the back of the case to create a pocket for a card or a folded bill. This is an incredibly practical addition that makes the case feel like a full phone wallet.

Knitting in the Round vs. Knitting Flat: Which Is Better for This Project?

Both methods produce excellent results, and the choice really comes down to personal preference and what you’re comfortable with.

Knitting in the round produces a seamless tube with a neater finish and is ideal if you dislike seaming. However, you’ll need double-pointed needles or a very short circular needle, which some knitters find fiddly on a small project like this. Working flat and seaming is more accessible for beginners and allows you to clearly see both the right and wrong sides of your work as you go. The seam, when done carefully with mattress stitch, is virtually invisible.

If you’re new to double-pointed needles, this project is actually a wonderful low-stakes way to try them. The circumference is small, the stitch count is manageable, and you don’t have to maintain that tension over a large surface area. Many knitters who learned to use DPNs on phone cases or small pouches found that the skill transferred naturally to socks and mittens afterward.

Caring for Your Knitted Phone Case

Once your case is finished, you’ll want to keep it looking its best. Here’s how to care for it based on your yarn fiber.

For wool: Hand wash in cool water with a gentle wool wash or a small amount of dish soap. Do not agitate — simply submerge, gently squeeze, and rinse. Lay flat to dry. Avoid the dryer, which will felt and shrink the case dramatically.

For acrylic: Machine wash on a gentle cycle in cool water, then lay flat to dry or tumble dry on low. Acrylic is very forgiving and holds its shape well, making it a low-maintenance option.

For cotton: Similar to acrylic — machine wash on gentle in cool or warm water and lay flat to dry. Cotton can be ironed on a low setting if it becomes wrinkled or misshapen.

Making Multiple Cases: A Gift Idea Worth Running With

Once you’ve made one phone case, you may find yourself wanting to make ten. This is a completely normal and encouraged impulse. A stack of knitted phone cases in different colors and textures makes a beautiful, cohesive handmade gift set — perfect for teachers at the end of the school year, for friends at the holidays, or for craft fair tables.

Because the project uses such a small amount of yarn, you can often make two or three cases from a single skein of worsted weight yarn. This makes it economical as well as fast. Keep a basket of finished cases on your craft table and you’ll always have a thoughtful gift on hand.

A Final Note on Making Things

There’s a reason patterns like this one have the phrase “make ALL the things” baked into their spirit. The joy of knitting isn’t just in the finished object — it’s in the process of turning raw fiber into something useful and beautiful with nothing but two sticks and your own two hands. A phone case won’t change the world, but it will make your pocket a warmer, cozier place, and that’s genuinely something worth celebrating.

Now pick up your yarn, cast on 34 stitches, and get making. You’ve got this.
