The right side is the face of your finished fabric — the side you want people to see

The right side (often called the RS) is the outside of your knitted piece, the side that shows in the finished garment. The wrong side (WS) is the back, the side that faces inward or stays hidden. In many stitch patterns, the two sides look noticeably different — one smooth and polished, the other bumpy or loose. In others, they look almost identical, which is why knitters mark which is which before they forget.

The difference matters because patterns often tell you to work differently on right-side rows than wrong-side rows. A knit stitch on the right side becomes a purl stitch when you work it from the wrong side, and that changes how your pattern looks. If you lose track of which side is which halfway through a sweater, you can end up with reversed shaping or a pattern that doesn't match the photo.

Key Takeaways

  • The right side is the face of your finished fabric; the wrong side is the back that stays hidden or faces inward.
  • In stockinette stitch, the right side is smooth and the wrong side is bumpy, making them straightforward to tell apart.
  • In reversible patterns like garter stitch or seed stitch, both sides look the same, so you must mark which is which before you forget.
  • Stitch markers, safety pins, or a piece of yarn tied to one edge will remind you which side you are on when you set the work down.
  • If you lose track partway through, count the bumps on the back of your work — the side with more visible bumps is the wrong side in most patterns.

How stockinette stitch reveals the difference

In stockinette stitch — knit on right-side rows, purl on wrong-side rows — the two sides look completely different. The right side is smooth and V-shaped, with neat columns of Vs running down the fabric. The wrong side is bumpy, with horizontal bars of yarn running across it. This bumpy texture is called the purl side, and it is unmistakable once you know what to look for.

If you are working flat (back and forth on straight needles or a circular needle), you will naturally see the right side after every knit row and the wrong side after every purl row. If you are working in the round on circular needles, you always see the right side as you work, and the wrong side stays hidden inside until you finish. This is one reason in-the-round patterns are easier for beginners — you never have to flip the work or remember which side is which.

Reversible patterns where both sides look the same

Some stitch patterns look identical on both sides. Garter stitch (knit every row) creates horizontal ridges that look the same front and back. Seed stitch (alternating knit and purl in a checkerboard) also looks nearly the same on both sides. Brioche stitch and some cable patterns can also be reversible, depending on how they are worked.

When both sides look the same, you cannot rely on appearance to tell them apart. Instead, mark one side before you start or as soon as you realize you cannot tell them apart. Use a safety pin, a stitch marker, or tie a piece of contrasting yarn to the edge of the right side. This mark stays with the work and reminds you which direction you are facing whenever you pick it up again.

How to mark the right side if you are unsure

The easiest marker is a safety pin clipped to the right side of your fabric at the edge. It will not slip out, and you can see it when ready when you pick up your work. A stitch marker — a small ring or clip — can also work if you thread it through a stitch on the edge rather than on the needle itself. Some knitters tie a short length of contrasting yarn through an edge stitch.

Mark the right side before you set the work down for more than a few minutes, especially if you are new to knitting. Once you have worked a few rows, the pattern becomes clearer and you may not need the marker anymore. But if you are working a complex pattern or taking a long break, the marker is worth the thirty seconds it takes to add.

What to do if you have already lost track

If you have worked several rows and cannot remember which side is which, look at the bumps. In most patterns, the wrong side has more visible bumps or texture. In stockinette, the bumps are obvious. In garter stitch, both sides have bumps, so this test does not help — you will have to pick a side and mark it, then stay consistent.

If you are in the middle of a pattern that has clear shaping (like a sleeve cap or a neckline), the pattern instructions may tell you which rows are right-side rows. Count backward from where you are now to find a row you remember working, then count forward to figure out which side you are on. This is tedious but more reliable than guessing.

Why patterns specify right side and wrong side

Patterns tell you to work differently on right-side and wrong-side rows because the stitch you make changes depending on which direction you are facing. A knit stitch on the right side looks like a V. The same stitch worked from the wrong side looks like a bump. If a pattern says "knit on RS, purl on WS," it is telling you to make the same visual effect on both sides — the V on the right, the bump on the wrong.

Shaping instructions also depend on which side you are on. A decrease on the right side (like a knit two together) slants one way. The same decrease worked on the wrong side slants the opposite way. If you work shaping on the wrong side by mistake, your armholes or necklines will slope the wrong direction, and the finished garment will not fit or look right.

Circular needles and the right side

When you work in the round on circular needles, the right side always faces you as you work. You never flip the fabric, so you never see the wrong side until the piece is finished. This means you do not have to remember which side is which — you are always working on the right side.

The trade-off is that you cannot work flat rows to create a seam or opening. If a pattern is designed for circular needles, it assumes you will work every round on the right side. If you need to work flat instead, you will have to adapt the pattern to include wrong-side rows, which is more advanced.

Frequently Asked Questions

What if my pattern does not say which side is the right side?

Choose whichever side looks better to you — the smoother or more polished side is usually the right choice. Mark it with a safety pin or yarn so you remember. Once you have decided, stay consistent for the whole project.

Can I knit a sweater and not worry about right and wrong sides?

Only if you are working in the round on circular needles, where you always see the right side. If you are working flat, you will have to flip the work every row, and you need to know which side you are on to follow the pattern correctly.

Does the wrong side ever show in a finished garment?

Yes — in garments with a folded edge (like a hem or a cuff), the wrong side of the fold shows on the inside. In reversible pieces like scarves or blankets, both sides show, so you may want to choose a pattern where both sides look equally good.

What if I knit a whole row on the wrong side by mistake?

If you notice right away, you can unravel that row and reknit it. If you do not notice until later, the mistake will show as a row that looks backwards compared to the rows around it. Whether it is worth fixing depends on how visible it is and how much work it would take to undo.

Is there a way to tell right and wrong side by counting stitches?

No — the stitch count is the same on both sides. The only reliable ways to tell are by looking at the texture (bumpy versus smooth in stockinette) or by marking one side before you forget.
