How to Knit a Hexagon – Complete Knitting Tutorial for Beginners and Beyond
Few shapes in knitting are as satisfying as the hexagon. Whether you’re working on a cozy blanket made of dozens of joined motifs, a stylish pouch, or decorative patches for a denim jacket, the hexagon is endlessly versatile. Its six equal sides give finished projects a geometric elegance that circles and squares simply can’t match, and once you understand the basic principle of increasing in the right places at the right time, you’ll be able to knit hexagons of virtually any size.
This tutorial will walk you through everything you need to know: the materials, the technique, the stitch counts, and some helpful tips to make your hexagons come out neat, flat, and beautifully even. By the end, you’ll have a finished hexagon in hand and the confidence to knit as many more as you like.
What You’ll Need Before You Start
Before casting on a single stitch, gather your materials. Having everything ready at the start makes the process smoother and more enjoyable.
Yarn. Almost any yarn works for knitting hexagons, but beginners tend to find medium-weight (worsted or DK) yarn the easiest to work with because the stitches are large enough to see and count clearly. Choose a smooth, light-colored yarn if this is your first attempt, because it will be much easier to spot your increases and avoid mistakes.
Knitting needles. You can knit hexagons flat on straight needles or in the round on double-pointed needles (DPNs) or a short circular needle. This tutorial begins with flat knitting, which is more accessible for beginners, but a note on the in-the-round method is included later. Check the yarn label for the recommended needle size and use that as your starting point.
A tapestry needle. You’ll need this to weave in your yarn ends at the finish.
Stitch markers. These are especially helpful for marking your six increase points if you’re knitting in the round.
Scissors and a ruler or measuring tape for checking your gauge and trimming ends.
Optional but very helpful: a blocking board and pins or a blocking mat. Blocking transforms a hexagon from a slightly wavy, uneven shape into a crisp, flat, perfectly geometric piece.
Understanding How a Knitted Hexagon Works
A hexagon has six corners. When you knit one from the center outward, which is the most common and most intuitive method, you are essentially growing six wedge-shaped sections simultaneously. At each of those six corners, you increase by two stitches every other row (or every round, if working in the round). The increases create the angle of each corner, and the sections between them form the flat sides.
This means your stitch count grows in a predictable, regular pattern. You start with a very small number of stitches — usually six — and add twelve stitches every increase row or round. As the hexagon grows, the sides get longer while the corners remain equally spaced. This is the same mathematical principle behind crochet granny hexagons and the natural geometry of a honeycomb.
The flat-knitting method works by knitting the hexagon in two halves: you start at the center with a provisional or backward-loop cast-on, knit one half outward to an edge, then return to the center, pick up stitches from the provisional cast-on, and knit the second half outward. Some knitters prefer to avoid the provisional cast-on entirely by knitting the shape in six separate triangular wedges and seaming them together — that method is mentioned briefly at the end for those who find it more intuitive.
For most knitters, though, the center-out flat method is the easiest to follow from a written pattern, so that’s exactly what this tutorial uses.
Step One – Cast On
For a worsted-weight hexagon using 5mm needles, cast on 6 stitches using a backward-loop cast-on or any cast-on method you’re comfortable with. If you’re using DK weight yarn and 4mm needles, 6 stitches is still a fine starting count.
Leave a tail of at least 15cm (6 inches) to weave in later.
If you want to work the full hexagon flat without a provisional cast-on, you can cast on 3 stitches to begin one triangular wedge, complete it, then sew the six wedges together at the end. This alternative method is described briefly at the close of this tutorial.
Step Two – The Setup Rows
Row 1 (Right Side): Knit all 6 stitches.
Row 2 (Wrong Side): Purl all 6 stitches.
These two rows establish your fabric before the increases begin. At this point your work looks like a tiny rectangle of stockinette — that’s perfectly normal.
Step Three – The Increase Rows
Now the hexagon begins to take shape. The increases happen on right-side rows only, at six evenly spaced points. For a 6-stitch start, those points fall every single stitch on the first increase row, and then every section grows by one stitch on each subsequent increase row.
Here is how the increase section works. The most common increase used for hexagons is the KFB (knit front and back) because it’s easy and nearly invisible in garter or stockinette stitch. You can also use M1L (make one left) and M1R (make one right) if you prefer a cleaner result with no little “bump” — but KFB is simpler for beginners.
Increase Row (Right Side): (KFB) repeat across all stitches. — 12 stitches.
Non-Increase Row (Wrong Side): Purl (if working in stockinette) or knit (if working in garter stitch) across all stitches.
Second Increase Row: (K1, KFB) repeat across — 18 stitches.
Non-Increase Row: Purl (or knit for garter) across.
Third Increase Row: (K2, KFB) repeat across — 24 stitches.
Non-Increase Row: Purl across.
The pattern here is clear: on each increase row, you knit one more plain stitch between increases than you did on the previous increase row. The number of stitches between increases increases by one each time, while the number of increases (6) stays the same.
So the progression looks like this:
Row 3: KFB six times (one knit section of 0 before each increase) — 12 sts
Row 5: K1, KFB six times — 18 sts
Row 7: K2, KFB six times — 24 sts
Row 9: K3, KFB six times — 30 sts
Row 11: K4, KFB six times — 36 sts
Row 13: K5, KFB six times — 42 sts
Continue in this fashion until your hexagon reaches the desired size. A hexagon worked to about 48 or 54 stitches on worsted weight yarn with 5mm needles will measure roughly 12–15cm (about 5–6 inches) across, which is a nice size for motif blankets, coasters, or ornamental patches.
Step Four – Binding Off
When your hexagon is the size you want, bind off on a right-side row using a standard bind-off or an elastic bind-off such as the Russian bind-off or Jenny’s Surprisingly Stretchy Bind-Off. An elastic bind-off helps the edges of the hexagon lay flat after blocking and gives the finished piece a more professional look.
To bind off normally: K2, pass the first stitch over the second stitch and off the needle, K1, pass the first stitch over — repeat from * to the end. Cut your yarn, leaving a 15cm tail, and pull the tail through the last stitch to secure it.
Step Five – Finishing
Thread the yarn tail from your cast-on through a tapestry needle and weave it in on the wrong side, working through the backs of several stitches so it doesn’t show on the right side. Weave in your bind-off tail the same way. Trim both tails close to the fabric.
Take a moment to admire your hexagon — even before blocking, you should be able to see the six corners taking shape.
Step Six – Blocking
Blocking is the step that many beginners skip, and it’s almost always a mistake to do so. Knitting fresh off the needles tends to curl, bunch, and look uneven. Blocking relaxes the fibers, opens up the stitches, and coaxes the piece into its final geometric shape.
To wet block your hexagon, submerge it in cool water and let it soak for about ten minutes. Gently squeeze out the water (don’t wring), roll it in a clean towel to absorb excess moisture, and then pin it to your blocking board in the shape of a hexagon. Use a ruler to ensure all six sides are equal in length, and pin each corner firmly. Leave it to dry completely — usually overnight.
The transformation is remarkable. What was a slightly lumpy piece of knitting will dry into a crisp, flat, clearly geometric hexagon.
Working the Hexagon in the Round
If you’re comfortable with double-pointed needles or magic loop technique, you can knit your hexagon entirely in the round, which eliminates the need for a provisional cast-on and produces a seamless piece in either stockinette or a textured stitch.
To work in the round, cast on 6 stitches and distribute them across three or four double-pointed needles (or use magic loop with a long circular). Place a stitch marker at the beginning of the round and additional markers between each of the six “sections” of two stitches each.
Round 1: Knit all stitches.
Round 2 (Increase Round): (KFB, KFB) six times — 18 stitches, with 3 stitches per section.
Round 3: Knit all stitches.
Round 4 (Increase Round): (K1, KFB, K1, KFB) or simply (K1, KFB) six times and adjust the marker placement — continue increasing at the two points within each section every other round.
Working in the round can be a bit confusing because you’re always on the right side and the math of the increases shifts slightly depending on whether you’re increasing at the corners or within the sections. Many knitters find it easiest to think of each of the six sections as a small wedge that grows by one stitch on each increase round. Place markers at each of the six corner points and work a KFB (or M1L/M1R pair) at each marker every other round.
The in-the-round method produces a lovely all-stockinette hexagon without purling, which some knitters find much more enjoyable.
The Six-Wedge Method
For those who find center-out hexagons confusing, there’s another approach: knit six identical triangles and seam them together. Each triangle starts at a point with 1 or 3 stitches and is increased at one or both edges on every other row until the desired side length is reached. Then the long edges of the six triangles are seamed together. This method is particularly popular when using multiple colors, because each wedge can be a different color for a striking pinwheel effect.
The seaming takes more time, but many knitters find the individual triangles easier to understand and execute, especially when learning.
Tips for Success
Working a consistent tension throughout your hexagon matters more than the exact needle size or yarn weight. If your tension fluctuates, some sections will be larger than others, and the finished shape won’t be truly hexagonal. If you notice yourself knitting more tightly as you work (a common nervous habit), consciously relax your grip on the needles every few rows.
Use stitch markers even when knitting flat. Placing a marker every 6 stitches (or at each “corner” position) helps you see immediately if you’ve miscounted, which is far easier to fix early than after several more rows.
Check your stitch count at the end of every increase row. A hexagon at 36 stitches should have exactly 6 groups of 6 stitches. If you’re off by one or two, it’s almost always easier to tink (unknit) back to the mistake than to try to compensate later.
Garter stitch (knit every row) is actually a lovely choice for hexagons. It doesn’t curl at the edges the way stockinette does, which makes blocking easier, and the ridged texture shows off the geometric shape beautifully. Seed stitch and moss stitch also work very well.
If you’re making many hexagons to join into a blanket, knit a gauge swatch for your chosen yarn and needle combination first, and make sure all your hexagons are the same size before seaming. Slight differences in gauge between motifs become very noticeable in a finished blanket.
How to Join Hexagons Together
Once you have multiple hexagons, you’ll want to join them. The most common methods are the mattress stitch seam worked with a tapestry needle, the three-needle bind-off (if you leave stitches live on the needle), and slip-stitch crochet join worked along the edges. Each method produces a slightly different look: mattress stitch is nearly invisible, three-needle bind-off creates a raised ridge that can be decorative, and crochet join is fast and produces a flat, flexible seam.
Hexagons tile together in a honeycomb pattern, with each hexagon sharing a side with up to six neighbors. Lay your hexagons out on a flat surface before joining to plan your arrangement, photograph it, and then join row by row from one end to the other, adding partial hexagons at the edges if you want a straight border rather than a jagged honeycomb edge.
Ideas for Using Knitted Hexagons
The hexagon’s versatility is part of what makes it so beloved among knitters. A single large hexagon blocked firmly becomes a beautiful trivet or table mat. Several hexagons seamed together make a cozy lap blanket or even a full throw. Smaller hexagons can be filled with lavender or wool roving and seamed closed to make sachets or ornaments. Hexagon patches are a classic way to mend and embellish denim, canvas bags, or children’s clothing. And hexagon motif blankets — often called “honeycomb blankets” — are among the most popular projects on every major knitting platform, loved for the way they let you work in small, portable pieces and assemble the finished object gradually.
Once you’ve mastered the basic hexagon, you can explore variations: working in two or more colors, adding a contrasting border round, working in brioche stitch for a squishy textured effect, or experimenting with self-striping yarn to let the color shifts create unexpected patterning across the shape.
Final Thoughts
Knitting a hexagon is one of those techniques that feels tricky the first time and completely natural by the third or fourth repetition. The key is understanding the rhythm of the increase rows and trusting the math — twelve new stitches added every increase row, the sections between increases growing by one stitch each time, the six corners always in the same relative positions. Once that logic clicks, you can adapt the method to any yarn weight, any needle size, any desired diameter.
Take your time on your first hexagon, count your stitches often, block it properly when you’re done, and notice how satisfying it is to hold a finished piece that is geometrically precise and made entirely by your own hands. That satisfaction is exactly what keeps knitters coming back to hexagons again and again — and before long, you may find yourself planning an entire blanket’s worth of them.
Happy knitting.
