Knitting a Raglan Sweater: Step-by-Step Tutorial and Tips

Knitting a Raglan Sweater: Step-by-Step Tutorial and Tips

If you’ve ever wanted to try your hand at knitting a sweater, a raglan sweater is a great place to start. Raglan sweaters are known for their comfortable fit and stylish design. Whether you’re an experienced knitter or a beginner, this step-by-step guide will walk you through the process of knitting your very own raglan sweater.

First, you’ll need to gather your materials. You’ll need a set of knitting needles in the size specified in your pattern, as well as your chosen yarn. It’s a good idea to choose a yarn that is suitable for sweaters, such as a soft wool blend. You’ll also need a tape measure, stitch markers, and a yarn needle for finishing.

Once you have your materials ready, you’ll need to choose your pattern. There are many different raglan sweater patterns available, ranging from simple designs to more intricate ones. Take some time to browse through different patterns and choose one that suits your skill level and style preferences.

Next, you’ll need to take your measurements. Raglan sweaters are known for their custom fit, so it’s important to take accurate measurements of your body. You’ll need to measure your bust, waist, hips, and arm length. Refer to your pattern for specific instructions on how to take these measurements.

With your measurements in hand, it’s time to cast on and start knitting. The raglan construction means you’ll be knitting each section of the sweater separately, starting with the collar and working your way down. Follow your pattern’s instructions for casting on and knitting the collar, and then continue working on the body and sleeves.

As you progress through your knitting, be sure to keep track of your stitch count and use stitch markers to mark the raglan increases and decreases. These markers will help you keep track of your progress and ensure that your sweater is coming out according to the pattern.

Once you’ve finished knitting all the sections of your raglan sweater, it’s time to seam them together. Use a yarn needle to seamlessly join the collar, body, and sleeves. This step requires some patience and careful attention to detail, so take your time and make sure that all your seams are neat and tidy.

Finally, once your sweater is seamed together, it’s time to add any finishing touches. This could include adding ribbing to the collar, cuffs, and hem, as well as weaving in any loose ends and blocking the sweater to give it a professional finish.

With these step-by-step instructions, you’ll be well on your way to knitting your very own raglan sweater. As you gain experience with this construction method, you may want to experiment with different stitch patterns or variations on the raglan design. The possibilities are endless, and knitting a raglan sweater is a satisfying and rewarding project that you’ll be proud to wear.

What is a Raglan Sweater and Why Knit One?

A raglan sweater is a type of sweater that is constructed with raglan sleeves. Raglan sleeves extend from the collar down to the underarm in one continuous piece, without any shoulder seams. This creates a distinctive diagonal seam that runs from the collar to the underarm.

Raglan sweaters are popular for several reasons:

  • Comfortable fit: Raglan sleeves offer a more relaxed and comfortable fit compared to traditional set-in sleeves. The seamless construction allows for ease of movement and less restriction on the shoulders.
  • Customizable style: Raglan sweaters are versatile and can be knit in a variety of styles, including pullovers, cardigans, and even hoodies. They can be knit with different necklines, stitch patterns, and lengths, making them suitable for different occasions and personal preferences.
  • Simple construction: Raglan sweaters are relatively easy to knit, especially for beginners. The construction involves knitting the body and sleeves separately, and then joining them together at the underarm. This simplicity makes them a great project for those who are new to knitting or want to try out a new technique.
  • Classic look: Raglan sweaters have a timeless appeal and are considered a staple in many wardrobes. They have been a popular choice for both men and women for decades, and their simple yet stylish design ensures they never go out of fashion.
  • Warm and cozy: Knitting your own raglan sweater allows you to choose the yarn and gauge, enabling you to create a warm and cozy garment that is perfect for colder seasons. You can select yarns with different fibers and textures to achieve the desired level of warmth and comfort.

Overall, knitting a raglan sweater is a satisfying and rewarding project. It offers a combination of comfort, style, and creativity, allowing you to craft a garment that fits your individual taste and preferences. Whether you are an experienced knitter or just starting out, a raglan sweater is a versatile and enjoyable project to tackle.

Materials Needed for Knitting a Raglan Sweater

To successfully knit a raglan sweater, you will need a few materials. Here’s what you’ll need:

  • Yarn: Choose a yarn that is appropriate for the pattern and your desired sweater. Different yarn weights and fiber compositions will create different textures and drape. Be sure to buy enough yarn to complete the project.
  • Knitting needles: Select the appropriate size and type of knitting needles for your yarn and desired gauge. Circular needles are typically used for raglan sweaters to accommodate the large number of stitches.
  • Stitch markers: These are essential for marking the raglan increases and other important points in the pattern. They can be simple plastic rings or decorative markers.
  • Tape measure: You will need a tape measure to check your gauge and to measure your progress as you knit.
  • Scissors: A pair of sharp scissors is necessary for cutting yarn and trimming loose ends.
  • Darning needle: Also known as a tapestry needle, this needle is used for weaving in loose ends and sewing up seams.
  • Pattern: Find a raglan sweater pattern that you like and make sure to have it on hand while you knit. The pattern will provide you with the instructions and measurements needed to complete your sweater.
  • Optional: Depending on your knitting preference, you may also want to have a stitch holder or scrap yarn to hold stitches, a row counter to keep track of rows, and a cable needle if the pattern calls for cable stitches.

Having these materials ready before you start knitting will ensure a smoother and more enjoyable knitting experience. Take the time to gather all the necessary materials and read through the pattern to familiarize yourself with the instructions before you begin.

Choosing the Right Yarn and Needles

When knitting a raglan sweater, it is important to choose the right yarn and needles to ensure the best results. The yarn and needles you choose will affect the drape, fit, and overall appearance of your finished sweater.


When selecting yarn for your raglan sweater, consider the following factors:

  • Weight: Choose a yarn weight that matches the recommended gauge for the pattern. This will ensure that your sweater turns out the correct size and has the desired drape. Common yarn weights for sweaters include bulky, worsted, and fingering.
  • Fiber Content: Consider the fiber content of the yarn, as it will affect the feel, warmth, and durability of your sweater. Popular fiber choices for sweaters include wool, acrylic, cotton, and blends.
  • Color: Select a yarn color that complements your style and wardrobe. Consider whether you prefer solid colors, variegated yarns, or self-striping yarns.
  • Yarn Amount: Look at the pattern to determine how much yarn you will need to complete your sweater. Purchase enough yarn to ensure you have sufficient yardage, and consider buying an extra skein to account for any mistakes or alterations.



The needles you choose will impact the gauge, stitch definition, and overall texture of your knitted fabric. Here are some factors to consider when selecting needles for your raglan sweater:

  • Size: Use the needle size recommended in the pattern to achieve the proper gauge. If you have a different gauge, you may need to adjust the needle size accordingly.
  • Type: Choose between straight, circular, or double-pointed needles based on your knitting preference. Circular needles are often preferred for knitting seamless raglan sweaters, as they can accommodate a large number of stitches.
  • Material: Needles come in a variety of materials, including bamboo, metal, and plastic. Consider the pros and cons of each material, such as flexibility, durability, and ease of use, to find the best option for your knitting style.

Ultimately, the right yarn and needles for your raglan sweater will depend on your personal preferences, the pattern specifications, and the desired outcome of your project. Take your time to explore different options and make choices that will result in a beautiful and comfortable finished sweater.

Step 1: Casting On

Casting on is the first step in knitting a raglan sweater. This process creates the foundation row of stitches that you will work with throughout the project. Follow these steps to cast on your stitches:

  1. Hold the yarn: Start by holding the yarn in your dominant hand. The end of the yarn should be at the back of your hand and the working yarn should be draped over your index finger.
  2. Create a slip knot: Take the end of the yarn and make a loop. Cross the end of the yarn over the loop, creating an “X.” Insert your hand through the loop, grabbing the end of the yarn and pulling it through the loop to create a slip knot.
  3. Secure the slip knot: Place the slip knot onto one of the knitting needles. Pull the working yarn to tighten the knot, but make sure it is not too tight, as you need to be able to slide the stitches along the needle.
  4. Begin casting on: Hold the knitting needle with the slip knot in your dominant hand. With your other hand, take the working yarn and drape it over your thumb, creating a loop. Insert the needle into this loop from right to left, and pull the loop snugly onto the needle.
  5. Continue casting on: Repeat step 4 until you have cast on the desired number of stitches. Make sure to keep the stitches evenly spaced along the needle.

Once you have cast on all the stitches for your raglan sweater, you are ready to move on to the next step: knitting the ribbing.

Step 2: Knitting the Body

Now that you have completed the sleeves, it’s time to move on to knitting the body of your raglan sweater. The body is the main part of the sweater that will cover your torso. Follow these steps to knit the body:

  1. Attach your working yarn to one of the underarm stitches from one of the sleeves. This will be the starting point for knitting the body.
  2. Using the Raglan Increase pattern, knit across the stitches of the back, making increases at each raglan marker. This will shape the body of your sweater and create the distinctive raglan sleeves.
  3. Continue knitting in the Raglan Increase pattern until the body reaches your desired length. You can try on the sweater as you go to ensure a proper fit.
  4. Once the body is the desired length, you will need to shape the bottom hem. You can do this by knitting a few rows in a ribbed or garter stitch pattern, or by using another stitch pattern of your choice.
  5. After shaping the bottom hem, bind off all stitches to finish the body of your raglan sweater.

Remember to keep track of your stitch count and raglan markers as you knit the body. This will help ensure that your sweater is symmetrical and has the correct proportions.

Now that you have completed the body, you are ready to move on to the final step: knitting the neckline and finishing touches. Stay tuned for Step 3!

Step 3: Creating the Raglan Shaping

Once you have finished knitting the body and sleeves of your raglan sweater, it’s time to create the raglan shaping. Raglan shaping creates diagonal lines that extend from the neckline to the underarm, giving the sweater a classic raglan look. Follow these steps to create the raglan shaping:

1. Divide Your Stitches: First, you’ll need to divide your stitches into four sections: front, back, left sleeve, and right sleeve. Count the number of stitches you have and divide it by 4. This will give you the number of stitches in each section. Place markers to help you identify each section.

2. Decrease Stitches: Begin the raglan shaping by decreasing stitches on either side of the markers in each section. This can be done using various types of decreases, such as knit 2 together (k2tog) or slip slip knit (ssk). The specific decrease you choose will depend on the stitch pattern you are using and your personal preference.

3. Repeat Decreases: Continue decreasing stitches every few rows until you reach the desired width for the raglan shaping. This will typically be determined by the size of the sweater you are making and the fit you prefer. Remember to alternate the decreases on the left and right sides of the markers to maintain symmetry.

4. Shape Neckline: Once you have reached the desired width for the raglan shaping, you will need to shape the neckline. This involves decreasing stitches in the front section of the sweater. You can choose to shape the neckline by continuing the raglan decreases or by using a different type of decrease, such as a centered double decrease.

5. Continue Knitting: After shaping the neckline, you can continue knitting the remaining stitches in each section until you reach the desired length for your sweater. This will typically be determined by the pattern or your personal preference.

6. Finish Off: Once you have completed the raglan shaping and reached the desired length, you can finish off your raglan sweater. This may involve binding off stitches, seaming the underarm seams, and adding any desired finishing touches, such as ribbing or a collar.

Creating the raglan shaping is an important step in knitting a raglan sweater. It adds visual interest and gives the sweater its distinctive look. Take your time and follow the instructions carefully to ensure a successful outcome.

Step 4: Knitting the Sleeves

Once you have completed knitting the body of your raglan sweater, it’s time to move on to the sleeves. The sleeves will be knitted separately and then attached to the body of the sweater during the finishing process.

Follow these steps to knit the sleeves:

  1. Measure the length of your arm from your underarm to your desired sleeve length. This will determine how many rows you need to knit for each sleeve.
  2. Using the same yarn and needle size as you did for the body of the sweater, cast on the required number of stitches for your sleeve.
  3. Begin knitting in the desired stitch pattern, following the same stitch pattern used for the body of the sweater. If there is no specific stitch pattern, you can continue knitting in stockinette stitch.
  4. Work the required number of rows for your sleeve length, keeping track of your progress with a stitch marker if necessary.
  5. Once you have reached the desired length for your sleeve, bind off all stitches.
  6. Repeat steps 2-5 to knit the second sleeve.

After you have finished knitting both sleeves, it’s time to attach them to the body of the sweater. Use a tapestry needle and yarn to sew the sleeves to the armholes of the sweater, matching the corresponding raglan seams.

Make sure to sew the sleeve seams securely, ensuring that the sleeves are evenly spaced and sit comfortably on your shoulders. Once the sleeves are attached, you can proceed with the remaining finishing steps, such as sewing the side seams and adding any desired ribbing or edging.

By following these steps, you’ll be able to knit beautiful raglan sleeves for your sweater, creating a seamless and professional-looking garment.

Finishing Touches: Neckline and Blocking

Once you have finished knitting your raglan sweater, there are a few finishing touches you can add to give it a polished look. One important step is to work on the neckline.

To create a neat and clean neckline, you can use a technique called ribbing. Ribbing involves knitting alternate rows of knit and purl stitches to create a stretchy and decorative edge. You can choose the number of stitches and rows for your ribbing based on your personal preferences and the overall design of your sweater.

Before starting the neckline ribbing, pick up stitches around the neck edge. This can be done by using a knitting needle or a crochet hook. The number of stitches to pick up will depend on the size of your sweater and the desired width of the neckline. Make sure to evenly distribute the picked-up stitches along the neck edge.

Once you have picked up the stitches, you can begin working the ribbing pattern. A common ribbing pattern for a neckline is a 1×1 rib, which means alternating one knit stitch with one purl stitch. Work the ribbing until you reach your desired length, then bind off the stitches. This will create a neat and stretchy neckline for your raglan sweater.

After completing the neckline, the next step is blocking. Blocking is the process of shaping and smoothing knitted fabric by gently wetting it and laying it flat to dry. This step helps to even out the tension, relax the stitches, and give the finished garment a professional look.

To block your raglan sweater, you will first need to soak it in lukewarm water with a mild detergent. Gently squeeze out the excess water, making sure not to wring or twist the fabric. Lay the sweater flat on a clean towel or a blocking mat, shaping it into the desired dimensions and smoothing out any creases or wrinkles.

You can use pins or blocking wires to help maintain the shape of the neckline and other sections of the sweater. Let the sweater dry completely before removing the pins or wires. This may take a day or two, depending on the thickness of your yarn and the ambient humidity.

Blocking is an essential step to give your raglan sweater a professional finish. It enhances the drape and fit of the fabric and ensures that your hard work in knitting the sweater pays off in the end.
