Free Crochet Smartphone Case Pattern – Crochet Bits

If you’ve been searching for a fun, practical, and completely free crochet project, you’ve landed in exactly the right place. This free crochet smartphone case pattern is perfect for beginners and intermediate crocheters alike, and it makes a wonderful handmade gift or a stylish accessory for your own everyday use. Whether you want to protect your phone from scratches, add a pop of color to your daily carry, or simply pick up your hook for a satisfying afternoon project, this pattern has you covered.

At Crochet Bits, we believe that crochet should be accessible, joyful, and functional. This smartphone case pattern checks every box. It works up quickly, uses minimal yarn, and results in a snug, cushioned pouch that keeps your phone safe wherever you go. Let’s dive into everything you need to know to get started.

Why Crochet a Smartphone Case?

Before we get into the pattern itself, let’s talk about why a crocheted phone case is such a brilliant idea. Store-bought phone cases are made from plastic or silicone, and while they do the job, they can feel cold, impersonal, and disposable. A handmade crochet case, on the other hand, has texture, warmth, and character. It’s uniquely yours.

Crocheted phone cases also offer a surprising amount of protection. The thick, textured fabric absorbs minor bumps and prevents scratches far better than a thin plastic shell. And because crochet is inherently stretchy, a well-made case can fit a range of phone sizes without needing to be customized for every model.

There’s also the creative satisfaction angle. This project takes just a few hours from start to finish, which means you get that deeply satisfying “I made this” feeling without committing to a weeks-long project. If you’ve ever wanted a quick win in your crafting life, a crochet smartphone case delivers.

Materials You’ll Need

One of the best things about this pattern is how few supplies it requires. Here’s what you’ll want to gather before you start.

Yarn: You’ll need approximately 50–70 yards of medium weight yarn (size 4 / worsted weight). Cotton yarn works exceptionally well for this project because it holds its shape, provides a firm stitch definition, and is slightly rigid, which helps the case maintain its structure. That said, acrylic yarn works beautifully too, especially if you want a softer, more flexible result. Choose any color or colorway you love — this is your chance to get creative.

Hook: A 4.0 mm or 4.5 mm crochet hook is recommended for worsted weight yarn. If you’re using a thinner yarn, size down accordingly. Gauge matters here since you want a snug fit for your phone, so swatch and adjust as needed.

Stitch marker: Just one, to mark the beginning of each round if you’re working in the round.

Tapestry needle: For weaving in your yarn ends at the finish.

Scissors: Any pair will do.

Optional: A button, snap, or small magnetic closure if you’d like to add a flap closure to the top of the case. You can also add a small loop of chain stitches to serve as a button loop.

Gauge and Sizing

Gauge for this pattern is approximately 16 single crochet stitches and 18 rows equal 4 inches (10 cm) using worsted weight yarn and a 4.5 mm hook.

Before you begin, measure your phone. The most important dimensions are the height and the width. Add about half an inch (1.25 cm) to each dimension to account for ease and to ensure your phone can slide in and out of the case without too much struggle. Remember that crochet fabric has stretch, so even if your case seems snug off the hook, it will accommodate your phone comfortably once you’ve used it a few times.

This pattern is written to fit a standard smartphone approximately 6 inches tall and 3 inches wide, which covers a large number of popular phone models. Instructions for adjusting the size are included throughout the pattern notes below.

Abbreviations and Stitches Used

This pattern uses US crochet terminology.

ch – chain
sl st – slip stitch
sc – single crochet
hdc – half double crochet
st(s) – stitch(es)
MR – magic ring (also called magic circle)
BLO – back loop only
rnd – round
rep – repeat

The primary stitch used in this pattern is the single crochet worked in the back loop only (BLO). Working in the back loop creates a ribbed, textured effect that gives the finished case a beautiful, intentional look. It also slightly increases the structure of the fabric, which is exactly what you want for a phone case.

Free Crochet Smartphone Case Pattern

Getting Started: The Bottom of the Case

This case is worked from the bottom up, starting with an oval foundation that forms the base of the pouch.

Foundation Oval:

Chain 10.

Round 1: Starting in the second chain from the hook, sc 8 across, then work 3 sc into the last chain (this rounds the bottom corner). Continue working along the opposite side of the foundation chain, sc 7, then work 2 sc into the first chain (this rounds the top corner). Join with a slip stitch to the first sc if working in joined rounds, or place a stitch marker to work in a continuous spiral. You will have approximately 20 stitches.

Round 2: Work 2 sc into the first stitch, sc in the next 7 stitches, work 2 sc into each of the next 3 stitches, sc in the next 7 stitches, work 2 sc into each of the last 2 stitches. You will have approximately 26 stitches.

Round 3: Sc in each stitch around, increasing by 2 stitches at each short end as needed to keep the oval flat. Approximately 30–32 stitches.

At this point, your oval should lie flat without curling or bunching. This is the base of your phone case.

Building the Sides

Now you’ll begin working upward to form the walls of the case. This is where the back-loop-only technique comes in.

Round 4: Working in BLO, sc in each stitch around. Do not increase. This round creates the “fold” between the base and the walls of the case and gives it that structured, almost box-like shape.

Rounds 5 through 25: Sc in each stitch around, working through both loops as normal. Continue until the case measures approximately 5.5 to 6 inches from the base. If your phone is taller, simply add more rounds until you reach the desired height. As a general guide, you want the top of the case to sit about a quarter inch above the top of your phone when the phone is nestled inside.

At the end of your final round, slip stitch to join, then fasten off and weave in your ends.

Adding a Ribbed Cuff (Optional but Recommended)

A ribbed cuff at the top of the case gives it a polished, finished look and also helps keep the phone from slipping out. This section is worked as a flat rectangle that wraps around the opening.

Row 1: Attach your yarn at any stitch around the opening. Chain 6. Turn.

Row 2: Sc in the second chain from the hook and in each chain across. You will have 5 stitches. Slip stitch into the next stitch along the opening edge of the case to anchor the cuff. Turn.

Row 3: Working in BLO, sc across all 5 stitches. Slip stitch into the next stitch along the case opening. Turn.

Repeat Row 3, anchoring with a slip stitch into the next stitch of the opening on every row, until you have worked all the way around the circumference of the opening.

Fasten off and seam the short edges of the cuff together to close it into a neat band. Weave in all ends.

Optional Flap Closure

If you’d like to add a flap to the top of the case, this is a simple addition that makes the case feel more secure and gives it a little extra style.

After completing the main body and before working the cuff, attach your yarn at the back center of the top opening.

Row 1: Ch 1, sc across approximately 16 stitches (or about half the total stitch count at the opening). Turn.

Row 2: Ch 1, sc2tog, sc across to the last 2 stitches, sc2tog. Turn.

Repeat Row 2 until the flap narrows to approximately 8–10 stitches wide and is about 1.5 inches deep.

Work one row of sc around all edges of the flap to neaten the edges, working 3 sc into each corner to prevent curling.

Attach a button to the front body of the case, and work a small chain loop at the center point of the flap’s lower edge to serve as a button loop. Alternatively, sew a snap closure to the inside of the flap and the outer face of the case’s front.

Tips for a Perfect Fit

Getting the right fit for a crochet phone case is all about checking your gauge and measuring as you go. Here are a few tips that will save you from having to frog (unravel) your work.

First, check the width early. After your first few rounds of the body section, slip your phone inside to test the fit. The case should feel snug without straining the stitches. If it’s too tight, consider going up half a hook size. If it’s too loose, go down half a size.

Second, measure the height as you go. There’s no penalty for pausing to lay your phone inside the case during construction. The visual check of seeing the phone peek just slightly above the rim is the clearest indicator that you’ve reached the right height.

Third, don’t skip the gauge swatch if this is your first time making this pattern. I know swatching feels like a delay, but a quick 4×4 inch swatch will tell you everything you need to know about whether your tension matches the pattern and whether you need to adjust.

Fourth, block your finished case if you’ve used cotton yarn. A light blocking will even out your stitches and help the case hold its shape beautifully over time.

Yarn Substitution Ideas

This pattern is wonderfully flexible when it comes to yarn choice, and experimenting with different fibers is part of the fun.

Cotton yarn, as mentioned, is the top recommendation for structure and durability. Paintbox Simply DK Cotton and Lion Brand 24/7 Cotton are both widely available, affordable, and come in gorgeous color ranges.

Wool or wool-blend yarn will give you a softer, more cushioned case with excellent stitch definition. The natural elasticity of wool also makes for a snugger fit.

Jute or hemp twine creates a rustic, earthy aesthetic and an incredibly firm structure. If you enjoy a boho or natural look, this is a fun choice.

Variegated or self-striping yarns can turn this simple pattern into something that looks far more complex than it actually is. Let the yarn do the decorating for you.

Velvet or chenille yarn produces an ultra-soft, plush case that feels luxurious in the hand. Just be aware that these yarns can be harder to work with for beginners, as the stitches are harder to see.

Customization and Embellishment Ideas

Once you’ve made the basic case, the sky is the limit when it comes to personalizing it. Here are some ideas to spark your creativity.

Adding a wrist strap is both practical and stylish. Simply crochet a long chain, fold it in half, and attach the looped end to the base of the case. A wrist strap turns your phone case into a clutch-style carry that keeps your phone secure in crowded places.

Embroidery is a beautiful way to add detail to a finished crochet surface. Floral motifs, geometric lines, and monograms all look gorgeous stitched onto the face of the case with a contrasting yarn or embroidery floss.

Surface slip stitching is another technique that adds color and pattern to a finished piece. Use a contrasting color to create stripes, zigzags, or other designs on the outer surface of the completed case.

Appliqués such as crocheted flowers, leaves, stars, or hearts can be made separately and sewn onto the case for a dimensional embellishment.

Mixing colors by working stripes or color blocks into the body of the case is perhaps the simplest way to add visual interest. Simply change colors at the end of any round by pulling the new color through on the final pull of your last slip stitch.

Caring for Your Crochet Phone Case

To keep your handmade case looking its best, a little care goes a long way.

Cotton cases can generally be hand washed in cool water with mild soap, then gently pressed (not wrung) and left to air dry. Reshape while damp for the best results.

Acrylic cases are typically machine washable on a gentle cycle, but check your yarn label to be sure.

Wool cases should be hand washed in cool water using a wool wash and handled carefully to prevent felting. Lay flat to dry.

Avoid exposing your case to prolonged direct sunlight, which can cause colors to fade over time.

Frequently Asked Questions

Can I make this case for a tablet instead of a phone? Absolutely. Simply increase the foundation chain length, work more increases to build a wider base, and continue the body section for more rounds. The same structure and techniques apply at any size.

What if my phone has a bulky protective case on it? Measure the dimensions of your phone with its case on and use those as your target measurements rather than the phone itself. You’ll likely need a slightly larger oval foundation and a few extra rounds in the body.

Can a beginner make this pattern? Yes, without question. If you know how to chain, work single crochet, and slip stitch, you have everything you need. The most advanced technique in this pattern is working in the back loop only, which is easy to learn and adds so much to the finished look.

How long will this project take? Most crocheters finish the basic version of this case in two to four hours. If you add the flap, cuff, and embellishments, you might spend a full afternoon on it, which is still a wonderfully achievable project.
