A knitting pattern is a set of written instructions that tells you which stitches to make, in what order, and how many times to repeat them

Patterns use abbreviations, symbols, and numbers to compress instructions into a compact form. Instead of writing "knit one stitch, purl one stitch" fifty times across a row, a pattern writes "K1, P1" and tells you to repeat it to the end. Learning to decode these abbreviations and follow the structure is the main skill — once you understand the system, you can read any pattern, whether it is for a straightforward dishcloth or a complex sweater.

Most patterns follow the same basic layout: a materials list at the top, then stitch abbreviations, then the row-by-row or round-by-round instructions. Some patterns use written instructions only; others add charts with symbols that represent each stitch. Both methods say the same thing in different languages.

Key Takeaways

  • Every pattern starts with a key that defines abbreviations like K (knit), P (purl), YO (yarn over), and K2tog (knit two together).
  • Numbers in parentheses or brackets tell you how many stitches you will have after completing a row or section.
  • Asterisks and brackets mark the start and end of sections you repeat, so "K2, *P1, K1* repeat to end" means knit 2, then alternate purl and knit until the row is finished.
  • Stitch charts use symbols in a grid where each square is one stitch and each row of squares is one row of knitting, read from bottom to top and right to left on wrong-side rows.
  • Gauge (how many stitches and rows fit in one inch) must match the pattern's gauge or your finished piece will be the wrong size.

Understanding abbreviations and what they mean

Every pattern includes a key listing the abbreviations used in that specific pattern. The most common ones appear in almost every pattern: K means knit, P means purl, YO means yarn over (an increase), K2tog means knit two stitches together (a decrease), and SSK means slip, slip, knit (another decrease). Some patterns add less common stitches like C4F (cable four front) or P2tog (purl two together).

The key also tells you which direction to work. Most flat knitting (knitting back and forth on straight needles) is worked from right to left on right-side rows and left to right on wrong-side rows. Circular knitting (on circular needles or double-pointed needles) is always worked in the same direction around. The pattern will state this, or you can infer it from the context — if the pattern says "RS" (right side) and "WS" (wrong side), you are working flat.

Numbers next to an abbreviation mean repeat that stitch that many times. K5 means knit five stitches in a row. P2, K1 means purl two, then knit one. If you see K1, P1 repeated across the entire row, the pattern will write it as "K1, P1 to end" or "K1, P1 rep to end" rather than listing it fifty times.

Reading repeat sections and understanding brackets

Patterns use asterisks, brackets, or parentheses to mark sections you repeat. An asterisk looks like this: *K2, P2* repeat to end. This means knit two, purl two, then do that same sequence over and over until you reach the end of the row. The asterisks mark where the repeat starts and stops.

Brackets work the same way but use square brackets: [K2, P2] repeat to end. Some patterns use both asterisks and brackets in the same instruction to show a repeat within a repeat — for example, *K1, [P1, K1] twice* means knit one, then purl and knit alternating twice, and repeat that whole sequence to the end.

Numbers in parentheses at the end of a row or section tell you how many stitches you should have after completing that row. If a row says "K2tog across (24 sts)" and you started with 48 stitches, you have decreased to 24. If your count does not match, you made an error in that row and should fix it before moving on. These stitch counts are your checkpoints.

How to follow a stitch chart instead of written instructions

A stitch chart is a grid where each small square represents one stitch and each horizontal line of squares represents one row of knitting. A key at the side of the chart shows what symbol in each square means — a blank square might mean knit, a dot might mean purl, a diagonal line might mean K2tog. Charts let you see the pattern visually instead of reading abbreviations.

Read a chart from bottom to top, because the bottom row is the first row you knit. On flat knitting, read right-side rows from right to left and wrong-side rows from left to right — the opposite of how you read English. On circular knitting, always read from right to left. The pattern will tell you which rows are right-side and which are wrong-side, or you can count: row 1 is right-side, row 2 is wrong-side, row 3 is right-side, and so on.

Charts often repeat horizontally. A pattern might show a small chart and say "repeat this 6-stitch pattern 8 times across the row." You knit the 6-stitch sequence eight times to fill the row. Some charts show the entire row; others show only one repeat and expect you to repeat it as many times as needed.

What gauge means and why it matters

Gauge is the number of stitches and rows that fit in one inch of knitted fabric. A pattern might say "gauge: 20 stitches and 28 rows over 4 inches in stockinette stitch on size 6 needles." This means if you knit a 4-inch square using size 6 needles and stockinette stitch (knit on right-side rows, purl on wrong-side rows), you should have 20 stitches across and 28 rows tall.

Gauge matters because if your gauge is different from the pattern's gauge, your finished piece will be the wrong size. If your gauge is looser (fewer stitches per inch), your sweater will be too big. If your gauge is tighter (more stitches per inch), it will be too small. Before starting a project, knit a gauge swatch — a small square at least 4 inches wide — in the stitch and yarn the pattern calls for, wash and dry it the way you will wash the finished piece, then measure it and count the stitches and rows.

If your gauge does not match, change needle size. Smaller needles make tighter gauge; larger needles make looser gauge. Test again until your gauge matches. This takes time but prevents finishing a sweater that does not fit.

Common pattern abbreviations you will see repeatedly

Beyond the basic K and P, these abbreviations appear in most patterns. YO (yarn over) creates a new stitch and a small hole, used for lace or buttonholes. K2tog (knit two together) and P2tog (purl two together) decrease by one stitch. SSK (slip, slip, knit) also decreases by one stitch but slants the other direction. Sl (slip) means move a stitch from the left needle to the right needle without knitting it. Inc (increase) or M1 (make one) adds a stitch.

Cables like C4F (cable four front) or C4B (cable four back) require a cable needle — you slip some stitches to a separate needle, knit the next stitches, then knit the stitches from the cable needle. Twisted stitches like K1tbl (knit one through the back loop) change the angle of the stitch. Decreases like SK2P (slip one, knit two together, pass slipped stitch over) or CDD (central double decrease) reduce multiple stitches at once.

Every pattern includes a complete key, so you do not need to memorize these. When you see an abbreviation you do not recognize, look it up in the pattern's key first. If it is not there, search online for the abbreviation plus "knitting" — most abbreviations are standard across the knitting world.

How to track your progress and fix mistakes

Mark off each row as you complete it. Use a row counter, a piece of paper with checkmarks, or a note on your phone — anything that keeps you from losing track of where you are. Patterns with many rows are straightforward to lose your place in, and reknitting five rows because you forgot which row you were on is frustrating.

If you notice a mistake several rows back, you have two choices: frog (pull out the yarn and reknit from that point) or tink (undo one stitch at a time, which is slower but safer). If the mistake is in the last row or two, tinking is usually faster. If it is more than three rows back, frogging is usually faster. Do not ignore mistakes in shaping rows (rows with increases or decreases) — they will throw off your stitch count and make later rows impossible to complete correctly.

If you get stuck mid-row, put your needles down and look at the pattern again. Read the abbreviation out loud. Count your stitches. Check the stitch count at the end of the last completed row. Often the problem is a misread abbreviation or a skipped stitch, not a fundamental misunderstanding of the pattern.

Frequently Asked Questions

What does "work even" mean in a pattern?

Work even means continue knitting in the same stitch pattern without increasing or decreasing until you reach the next instruction. If a pattern says "increase one stitch at each edge every other row 10 times, then work even for 2 inches," you stop increasing after the tenth increase and just knit straight for 2 inches.

Why does my pattern say different stitch counts for different sizes?

Patterns for multiple sizes (small, medium, large) list instructions for each size in parentheses or brackets. Before you start, circle or highlight all the numbers for your size throughout the entire pattern. This prevents you from accidentally knitting a small when you meant to knit a large.

Can I use a different yarn than the pattern calls for?

You can, but you must match the gauge. If the pattern calls for a worsted-weight yarn and you use a bulky yarn, you will need larger needles to hit the same gauge. Check the yardage too — if the pattern calls for 1000 yards and your yarn has only 800 yards, you may not have enough to finish.

What if the pattern uses a stitch I have never done before?

Search online for the stitch name plus "how to" — most common knitting stitches have video tutorials. Practice the stitch on a small swatch before starting the actual project. Many knitters keep a practice swatch going specifically to try new stitches before committing to a large project.

Do I have to follow the pattern exactly, or can I change things?

You can change things, but understand the consequences. Changing yarn weight, needle size, or stitch count will change the finished size and fit. Changing colors or stitch patterns is usually safe. If you are new to knitting, follow the pattern as written the first time — once you understand how patterns work, you can experiment with confidence.
