How to knit a Basic Beanie without a pattern – Part 1: Brim and Body

I have read several Facebook posts and Ravelry forums where new knitters are asking about how to knit a basic hat. There are many basic beanie style hat patterns available for free on Ravelry, including one of mine: Basic Beanie Hat.

But the truth is that a basic beanie hat is fairly easy to knit without any pattern if you are familiar with its structure and know your gauge for the yarn you want to use for the hat. So this post is about the basic structure of a beanie, knit in the round.

Now, a beanie can be knit top down or bottom up, but if you look at most patterns, they are written with a bottom-up construction and this will be the approach I will follow here. There are three parts to a basic beanie: The brim, the body, and the crown. The brim of a beanie is usually done in either 1×1 ribbing (k1,p1) or 2×2 ribbing (k2,p2). The length of the brim can be relatively short – and intended to not be folded, or it can be longer so that it will be worn with the brim folded.

The body of a beanie is the part of the hat that covers the head from just above the ears to where the crown is formed. The length of the body varies according to the size of the hat, with children’s hats being shorter than an adults’ and Men’s hats are usually longer than Women’s. For a basic beanie this length is approximately the length from the top of the head to the bottom of the earlobe or half the length of measuring from the bottom of one earlobe to the other up over the top of the head.  

The crown of a beanie is the area that covers the top of the head and is shaped by making decreases to form a circle that is closed at the very top.

To begin knitting the basic beanie you need to do a little math. You need to know what circumference you want it to be. If you have the measurement of the circumference of the head of person you want to fit, you can use that. If you don’t know the circumference, then you can use a standard size chart for the measurements. See the chart below. For a women’s head, I usually use a circumference of 21 – 22 inches as a starting point.

Knitted beanies are made with negative ease. Now what do I mean by that? Negative ease means that the knitted hat will be smaller than the actual circumference and I usually factor in about 10% negative ease for my beanies. This gives the hat a good fit and it hugs the wearer’s head and stays in place. Using an example of a 21 inch circumference, the knitted circumference with 10% negative ease is 19 inches. (10% of 21 = 2.1; 21-2 = 19 or if you prefer: 21 x 0.9 = 19)

You are now ready to determine how many stitches to cast on to start the brim of the beanie. For this you will need your stitch gauge in stitches per inch (spi). I usually have a gauge of 5 spi with worsted weight yarn, so in this example, I multiply 19 inches by 5 sts which gives me 95 sts. However, if I am doing 1×1 ribbing, I need an even number of stitches, so I can either round down to 94 or round up to 96 sts. If I do 2×2 ribbing, I need an even number of stitches, but the number also has to be divisible by 4. In this example, 96 is divisible by 4, so I would start with 96.

For a Women’s beanie, I usually like to knit the ribbing to a length of approximately 2 inches and then start the body. For a basic beanie, I knit the body in stockinette stitch. The body area is where you can add various textured stitch patterns or knit stripes using different colors of yarn. But the very basic beanie is knit in stockinette stitch.

The length of the hat is determined by measuring the length of the wearer’s head from the lower earlobe to the top of the crown. Another way is to measure the head from the bottom of one earlobe over the top of the head to the bottom of the other earlobe and then divide that number by 2. For a women’s hat, I usually use a length of 10.5 to 11 inches, for a men’s hat I use 11 to 11.5 inches. See the standard size chart above for further information. The crown of the hat is approximately 1/3 of the total length of the hat. So, once the ribbing is done, you knit the body to the desired length where the crown shaping starts (measured from the cast on edge). In my example of a women’s hat with a total length of 11 inches, I would knit to a length of 7.5inches. The remaining length of the hat is where the crown is shaped using decreases.

My next post covers things you need to consider to knit the crown of the beanie.

How to Knit a Basic Beanie without a Pattern — Part 2: Crown ShapingHow to Knit a Basic Beanie without a Pattern — Part 2: Crown Shaping

In my previous post, I discussed the basic structure of a basic beanie hat and how to knit the brim and the body of the hat. Once you have knitted the hat to the desired length before the start of the crown shaping, you have basically knit a cylinder as shown below.

If you look at the top of the cylinder, it is a circle – and this is the area where you shape the crown by gradually decreasing stitches to close the top of the hat. I usually decrease my stitches down to somewhere between 6 to 12 stitches and then finish the top of the hat by breaking the yarn and using the tail to close the very top of the hat.

Shaping the Crown: The shape of the crown is determined by the number of stitches you need to decrease, the type of decreases you use and how frequently you make your decreases.

Basic beanies usually have either a “spiral” shaped crown or a “wedge” shaped crown. Spiral shaped crowns are made by dividing the number of stitches into an equal number of segments where the decreases are made. The number of segments can be 5, 6, 7, or 8. The number you choose depends upon the total number of stitches and whether the total is evenly divisible by the number of segments. For example, 96 stitches can be divided into 6 equal segments of 16 stitches, or it can be divided into 8 equal segments of 12 stitches. If you have a number of stitches that cannot be evenly divided, then you will need to decrease your stitches down to a number that can be evenly segmented.

Typically, the decrease used for crown shaping is K2Tog which is a right-leaning decrease. You can also use the SSK decrease which leans left. However, you need to use only one of these two decreases in order to knit the spiral shape for your crown.

A wedge-shaped crown has only 4 segments. If you want this shape for your crown, you will divide your stitches by 4 and then use double decreases as you shape the crown. Using 96 stitches as an example, you would have 4 segments of 24 stitches.

To decrease you can use a combination of K2Tog and SSK at each point of decrease or you can use a Central Double Decrease(CDD).

I usually place a stitch or 2 between the K2Tog and SSK decrease when making the wedge-shaped crown. This gives the top of the hat a decorative ridge. The CDD makes a decorative line itself.

Rate of Decreases: Typically, I start crown decreases at a rate of every other round – where I decrease in each segment until I have knit approximately 1.5 inches and then I switch to decreasing every round until I am down to somewhere between 12 and 6 stitches. This is based on my experience.

Calculating Decrease Rates: I know it’s a lot of math, but here goes: To calculate your own rate of decrease, you need to know the number of rows that remain for the crown of the hat and your row gauge. The crown of the hat is approximately 1/3 of the total length of the hat. For example, the total length of the hat is 11 inches  — and 1/3 of this is 3.7 inches. Using a row gauge of 7 rounds per inch. 3.7 x 7 equals 25.9 rounds (round up to 26 rounds). I need to decrease from 96 stitches to 12 stitches at a rate of 6 sts per decrease round. This gives me 14 sets of decreases (96-12 = 84, 84/6 = 14). Dividing the total number of rounds by the number of decrease rounds gives me 1.9. Now I can opt to decrease EOR over 28 rows, which makes my hat slightly longer, or I can decrease EOR for 20 rows (decreasing 60 sts) and then decrease every row for 6 rows (decreasing 36 sts) and end with 10 sts to close the top of the hat. Either way will give me a hat with a close-fitting crown.

I have now covered how to make a basic beanie hat without using a pattern. Give it a try using your choice of yarn and your gauge. Happy Knitting. 🙂

Designing a Sweater without a PatternDesigning a Sweater without a Pattern

In previous posts, I have discussed how to use Elizabeth Zimmerman’s Percentage System (EPS) to design and knit a sweater and how to modify a written pattern to adjust for changes in sizing and/or gauge. Today, I will briefly describe the process of designing a sweater without a written pattern. I learned this process in depth when I first knitted a sweater using my knitting machine. Knitting garments on a knitting machine requires extensive set-up and calculations before you can even begin to knit. Regardless of whether you are hand knitting or machine knitting – the process and calculations are the same.

As in the previous design techniques, you start with a good set of body measurements and a gauge swatch to determine your stitch and row gauge. You will also need to factor in the amount of ease you wish to have in your completed sweater.

Any sweater has several basic elements: The front & back, the sleeves and the neck. Sweaters come in two basic forms – the pullover and the cardigan. If you take a minute to think through all the sweaters you have seen, you will realize that all of them are some variation of these two basic forms. So, let’s start by breaking down the elements of a basic pullover sweater.

Elements of a Pullover Sweater:

  • The Front & Back – in a very basic design, the front and the back are the same up to the point where one shapes the neckline. The Front and Back make up the tube of fabric that goes around the entire body – thus, the back consists of one-half of the total number of stitches needed for the body/chest measurement and the front has the other half. In our basic design, the back/front is essentially a rectangle – and you need to determine the width and the length from your own measurements. If you plan to knit this sweater in the round, then you will calculate the total number of stitches based upon the body/chest measurement plus ease. [(BM + Ease) X SPI]. If you plan to knit this sweater in pieces and then sew the pieces together, you will calculate the number of stitches needed for the front/back by dividing the Body/chest measurement by two and then adding in Ease and multiplying by your stitch gauge. [((BM/2) + Ease) X SPI]. For a set-in sleeve, you will also need to calculate the shaping of the armhole. When knitting in the round, at the point you begin shaping the armholes, it is best to knit flat and knit the front and back separately.
  • The Neck – the most basic neck for a pullover sweater is a round or crew neck shape. In our basic sweater design – a portion of the stitches of the center back are used for the back of the neck, while in the front there is some shaping done to make the front of the neck slightly lower than the back. The stitches not used in the neck are used for the shoulders and form the shoulder seams of the sweater. It is best to use live stitches for necklines. This allows you the needed stretch for the fabric to go over the head of the wearer. One must also keep in mind that the average woman’s head has a circumference of 22 inches. Thus, there needs to sufficient width allocated to the neck to allow the head to pass through it.Back Neck – for the basic sweater pattern, the back does not have any shaping to it. It is simply divided into three sections: Left shoulder, Neck and right shoulder. The number of stitches assigned to the back neck stitches is somewhat proportional to the chest measurement. Generally, the wider the chest, the larger the neck circumference. In this basic sweater design, there should be an equal number of stitches allocated to the shoulders, with the remaining stitches placed on hold for the neck. You determine the number of back neck stitches by multiplying your stitch gauge by the width of the back neck. You then subtract the number of back stitches from the total number of stitches for the back at the shoulders – this will give you the number of stitches for the shoulders. This number needs to be divisible by 2, so you may need to take 1 stitch from your neck stitches to even it out.

    Front Neck – the shaping for the front neck begins below the last row of the shoulder. For women, the depth of the neckline starts 2.5 to 3 inches below the shoulder, for men, the depth is 3 inches to 3.5 inches and for children the depth is 1.5 to 2.5 inches. This depth is entirely a matter of preference. The front neck is shaped as a semi-circle by gradually eliminating stitches on either side of the center front neck stitches. Thus, the center front stitches are placed on hold and then decreases are done on either side of these stitches as you knit up to the shoulders. This shaping will occur concurrently with the armhole shaping

  • The Sleeves – the most common styles of sleeve in commercial sweaters are the drop-sleeve and the set-in sleeve. For this design, I will cover the set-in sleeve. A Set-in Sleeve joins the body of the sweater at the armhole and the top of the shoulder seam. Set-in sleeves require shaping at the top of the sleeve itself as well as corresponding shaping in the front and back. The shaping is made by a series of bind-offs, increases and/or decreases. To design your sleeve you must have your sleeve length, the width of the sleeve at the armhole, the width of the sleeve at the elbow and the width of the sleeve at the wrist. You also need the depth of the armhole. There are quite a few calculations required to be able to knit a properly fitting set-in sleeve. You begin by calculating the shaping of the sleeve from the wrist to the underarm and then calculate the shaping required to form the rounded sleeve cap. Shaping is achieved by a series of increases from the wrist to the underarm, followed by bind-offs and decreases to form the sleeve cap.

Now let’s look at a basic cardigan sweater.

Cardigans are most often knitted flat – either in separate pieces or in as a one wide piece on a long circular needle. They can be knitted in the round using a steek to separate the two fronts when finishing the sweater. Shaping for armholes and neckline are mirrored for the right and left fronts. In addition, there is a knitted band of fabric that overlaps at the center front – this band can be knitted concurrently with the front using a pattern stitch or can be added to the front by picking up stitches along the center front edge after the front has been knitted.

The calculations for this sweater are essentially the same as for our basic pullover – with the exception of the front. A cardigan sweater has two front pieces that meet and overlap in the center of the garment. This means that each front piece is one-half of the front piece of a pullover sweater, plus some added width for the overlapping parts(buttonbands or borders). In our basic sweater design, you simply add the desired width of the buttonband to each front piece. For example, the front on our pullover measures 40 inches. For our cardigan, each front piece would be half of that or 20 inches and the buttonband would be 2 inches wide: 20 + 2 = 22 inches. My Excel Spreadsheet includes a section on calculating the fronts for a cardigan.

I have created an Excel Spreadsheet for all the calculations required for a basic pullover with a set-in sleeve. Click here to download the spreadsheet: Sweater Calculator.

Using this calculator and your own gauge, you now have all the calculations required to knit your pullover sweater. You can knit this sweater from the top down or from the bottom up. The shaping for a top-down sweater is done in the reverse order of a bottom-down sweater.

Today I have briefly outlined the basics of designing your own sweater using two basic sweater designs. From these two basic designs, you can create a sweater according to your own measurements out of any weight yarn. I recommend you give it a try.
