How to Crochet a Phone Case (Free PDF Pattern)

A crochet phone case is the quickest way to give your phone a handmade home. This little pouch fits snugly around your phone, protects it from scratches in your bag, and works up in an evening from a small ball of cotton yarn.

Below I am sharing everything I love about this make: the clever oval base, the seamless tube body, and the closure options that keep your phone secure. At the end, you can grab my free crochet phone case pattern to make your own.

Why a Crochet Phone Case Is Worth Making

A phone case is the perfect small project. It uses only basic stitches, works up fast, and solves a real everyday problem: a phone rattling loose in a bag full of keys. The dense cotton fabric cushions bumps and keeps the screen free of scratches, and because you made it, the fit is exactly right for your phone.

It is also a wonderful stash buster. One case takes only 40 to 60 grams of worsted-weight cotton, so that half ball sitting in your basket finally has a purpose. If you enjoy small accessories that work up quickly, our crochet pouch uses similar skills in a zippered version.

How a Crochet Phone Case Is Built

A good phone case has three parts: a flat oval base, a seamless tube body, and a closure that keeps the phone inside. Each one has a simple rule behind it.

The Oval Base

The base starts with a foundation chain worked around both sides to form an oval. A chain of 20 gives you 40 stitches around, which fits most modern phones with a little ease. Work the first round around both sides of the chain, increasing at each end to keep the oval flat. This crochet phone case from Yarn Nest Studio shows the same oval-base method with clear photos.

The Seamless Tube

Once the base is done, you simply keep crocheting upward in rounds with no seaming. Work in a continuous spiral of single crochet for about 27 rounds, or until the tube reaches the top of your phone. The spiral means there is no visible seam running up the side, and the fabric stays smooth and even all the way around.

Closure Options

The simplest finish is a ribbed cuff: work three rounds of single crochet in the back loop only, which cinches the top just enough to grip the phone. For extra security, add a buttonhole strap (a chain-8 loop at the back) with a button sewn to the front, or weave a drawstring cord through the top round. This alternating phone pouch from CrochetNCrafts uses a bone ring button for a polished look.

Yarn, Hook, and Size

Worsted-weight (#4) cotton is the best choice for a phone case. Cotton is dense, washable, and does not stretch out the way acrylic can, so the case keeps its snug fit. You need only 40 to 60 grams, and a 4.0 mm hook gives a tight fabric at a gauge of about 16 single crochet stitches per 10 cm.

Size the case to your phone: the width should be your phone’s width plus its thickness plus about 1 cm of ease. A standard case finishes about 7 inches tall, but the pattern is fully resizable, just add or remove foundation chains to change the width. If you like larger carriers for your tech, our crochet laptop sleeve scales the same oval-base idea up to laptop size.

Using and Styling Your Phone Case

A phone case earns its place in your daily carry. Slip it in your tote to keep the screen scratch-free, or add the optional wrist strap (a simple chain-55 loop) and carry your phone on its own for quick errands. The cotton fabric also wipes clean, which is more than you can say for most store-bought cases.

Make them in batches for gifts. Everyone has a phone, and a handmade case in the recipient’s favorite color beats a generic plastic shell every time. Pair it with our crochet tote bag for a matching handmade set that looks intentional, not accidental.

Frequently Asked Questions

What yarn is best for a crochet phone case?
Worsted-weight (#4) cotton. It is dense, washable, and holds its shape without stretching, which keeps the fit snug over time.

What hook size should I use?
A 4.0 mm hook with worsted cotton gives a tight, protective fabric. A 4.5 mm hook works too if you crochet tightly.

How do I size the case for my phone?
Measure your phone’s width and thickness, then add about 1 cm of ease. Adjust the foundation chain length to match; the pattern works with any starting chain count.

Will the case stretch out?
Cotton holds its shape far better than acrylic. The ribbed cuff at the top also helps the opening keep its grip.

Can a beginner make this?
Yes. The basic version uses only single crochet in spiral rounds, which is one of the easiest techniques in crochet. The button version adds a little more skill.

How do I add a wrist strap?
Chain 55, slip stitch back along the chain, and sew both ends firmly to the side of the case near the top.
