What a knitting pattern tells you and how to use it
A knitting pattern is a set of written instructions that tells you what yarn to buy, what needles to use, and exactly which stitches to make in which order. Patterns look like a foreign language at first—full of abbreviations like "k2tog" and "yo"—but they follow a consistent logic. Once you learn what the abbreviations mean and how to read the layout, you can follow any pattern, whether it's for a straightforward dishcloth or a complicated sweater.
The pattern itself has two main parts: the materials list at the top (yarn weight, needle size, notions like buttons) and the stitch-by-stitch instructions below. The instructions are usually organized by sections—cast on, ribbing, body, armholes, and so on. Each line tells you how many stitches to work and what stitch to use. Numbers in parentheses or brackets tell you how many stitches you should have after that row.
Key Takeaways
- Every pattern starts with a materials section that lists yarn weight, needle size, and finished measurements—check these before you buy yarn.
- Abbreviations like "k" (knit), "p" (purl), "k2tog" (knit two together), and "yo" (yarn over) are standard across all patterns and appear in a key at the top or bottom of the pattern.
- Asterisks and parentheses show you which stitches to repeat; for example, "k2, p2" repeated means you work those four stitches over and over across the row.
- The stitch count in parentheses at the end of each row tells you how many stitches should be on your needle—use this number to catch mistakes before you go too far.
- Patterns written in rows are read right to left on odd rows (the front) and left to right on even rows (the back), which is the direction your yarn naturally flows.
Understanding the materials section
The top of every pattern lists what you need before you cast on. This section includes yarn weight (such as worsted, DK, or bulky), the total yardage required, needle size, and any notions like buttons, stitch markers, or a tapestry needle. Pay close attention to yarn weight—it is not the same as thickness. A pattern written for worsted weight will not work the same way with fingering weight yarn, even if the yardage looks similar.
The materials section also gives you finished measurements: the width of the garment when laid flat, the length from shoulder to hem, sleeve length, and sometimes ease (how much extra room is built in). If you are making a sweater, compare the finished chest measurement to your actual chest measurement and add the ease amount. A sweater with 2 inches of ease will fit closer to your body than one with 4 inches. This is where many knitters go wrong—they assume a size number means the same thing across all patterns, when in fact the finished measurements are what matter.
Decoding abbreviations and stitch symbols
Every pattern includes a key that explains what each abbreviation means. The most common ones are k (knit), p (purl), k2tog (knit two stitches together as one), p2tog (purl two together), yo (yarn over—wrap yarn around needle to make a new stitch), ssk (slip, slip, knit—a left-leaning decrease), and inc (increase). Some patterns use symbols instead of letters, especially if they are translated or charted. A chart is a grid where each square represents one stitch and each row of squares represents one row of knitting. A filled square might mean knit, an empty square might mean purl, and a small loop might mean yarn over.
The key to reading abbreviations is to look them up the first time you see one. Write them on a sticky note next to your pattern or bookmark the key page. After you work through a few rows, the abbreviations become automatic. Do not try to memorize them all before you start—you will forget them, and the pattern will tell you what you need to know when you need to know it.
How to read row-by-row instructions
Row-by-row instructions are written as a sequence of stitches and abbreviations. A typical row might read: "Row 1: k1, p2, k4, p2, k1 (10 sts)." This means knit one stitch, purl two stitches, knit four stitches, purl two stitches, knit one stitch. The number in parentheses at the end tells you that after you finish this row, you should have 10 stitches on your needle. If you have 11 or 9, you made a mistake somewhere in that row and should fix it before moving on.
When you see an asterisk or the word "repeat," it means you work those stitches more than once across the row. For example, "k2, p2, repeat from * to end" means you work k2, p2, k2, p2, k2, p2 and so on until you run out of stitches. The pattern assumes you have the right number of stitches to make this work evenly. If the pattern says "repeat from * to last 2 stitches, k2," it means work the repeat as many times as it fits, then knit the last two stitches separately.
Reading charts and colorwork patterns
A chart is a grid where each small square represents one stitch and each row of squares represents one row of knitting. Charts are read from the bottom up (because you knit from bottom to top) and from right to left on the first row, then left to right on the second row, and so on—the same direction you read text rows. Different colors or symbols in the squares tell you which yarn color to use or which stitch to work. A legend at the side of the chart explains what each symbol means.
Charts are especially useful for colorwork (stranded knitting, where you carry two colors across a row) and lace patterns (where yarn overs and decreases create holes). Some knitters find charts easier to follow than written instructions because you can see the pattern taking shape as you look at the grid. If your pattern has both a chart and written instructions for the same section, you can use whichever one makes sense to you. Many knitters use the chart for the first repeat and then switch to the written instructions once they understand the pattern.
Keeping track of where you are in the pattern
The easiest way to avoid losing your place is to print the pattern and use a highlighter or a ruler to mark the row you are working on. Move the ruler down as you finish each row. If you are using a digital pattern on a tablet or phone, use the zoom function to make the text larger and take screenshots of the section you are working on. Some knitters use a row counter (a small tool that clips to your needle) or straightforward mark off rows on a piece of paper as they go.
Keep a notebook next to your knitting and write down the row number every time you set your work down. If you have to rip back (pull out stitches to fix a mistake), you will know exactly where you were. Also note any changes you made to the pattern—if you added an extra inch of ribbing or changed the color—so you remember what you did if you want to make the same project again.
Common mistakes when following patterns
The most common mistake is not checking the stitch count after each row. If the pattern says you should have 24 stitches and you have 26, you added two stitches somewhere—usually by accidentally making a yarn over or not decreasing when you were supposed to. Catching this early means you only have to rip back a few rows instead of many. The second mistake is confusing yarn weight with thickness. A pattern written for DK weight will not work with worsted weight yarn, even though worsted looks thicker. The finished garment will be too large and the fabric will be loose.
A third mistake is not reading the entire pattern before you start. Patterns sometimes have special instructions at the end (like "seam the sleeves before weaving in ends") or notes about gauge that change how you should approach the project. Spending five minutes reading the whole pattern first saves you from having to unravel work later. Finally, do not assume that a size number (like "size medium") means the same thing in every pattern. Always check the finished measurements and compare them to your actual measurements plus the ease amount.
Frequently Asked Questions
What does "work even" mean in a pattern?
It means continue knitting in the same stitch pattern (usually stockinette stitch, which is knit on the front and purl on the back) without increasing or decreasing stitches. You are just repeating the same row over and over until the pattern tells you to do something different, like start shaping an armhole.
Why does my pattern say "k1 tbl"?
"Tbl" means through the back loop. Instead of inserting your needle through the stitch the normal way, you insert it through the back of the loop. This twists the stitch slightly and is often used for ribbing or edge stitches to make them look neater. The pattern key will explain this abbreviation if it appears.
What if the pattern has a mistake in it?
Check the publisher's website or Ravelry (a knitting database) to see if other knitters have reported the same error and posted a correction. If you think you found a mistake, count your stitches and check the row number to make sure the error is in the pattern and not in your knitting. Many patterns have errata pages that list corrections.
How do I know if my gauge is right?
Patterns include a gauge number, usually written as "18 stitches and 24 rows over 4 inches in stockinette stitch on size 6 needles." Knit a small swatch (a practice piece) using the yarn and needles the pattern calls for, then measure how many stitches and rows you have in a 4-inch square. If your gauge matches, you are ready to start. If you have more stitches in 4 inches, your gauge is too tight and you need larger needles.
Can I change the size of a pattern?
Yes, but it requires math. You need to know your gauge and the finished measurements you want. Multiply your stitch gauge by the width you want, then increase or decrease the cast-on number by that amount. You will also need to adjust the length and sleeve cap shaping. Many knitters find it easier to choose a size close to what they want rather than trying to resize the entire pattern.
