The Checkerboard Pattern Uses Two Colors and Alternating Knit Blocks

A checkerboard pattern in knitting is made by working small squares of one color, then switching to a second color for the squares beside them, creating the visual effect of a game board. The most common method uses intarsia (carrying yarn inside the work) or stranded colorwork (carrying both colors across the row), though intarsia produces a flatter, cleaner result for large color blocks.

The pattern works best on stockinette stitch (knit on the right side, purl on the wrong side) because the smooth surface shows the color changes clearly. You'll work in blocks rather than row by row—typically 8 to 12 stitches wide and the same number of rows tall per square—so the checkerboard reads as distinct squares rather than a striped mess.

Key Takeaways

  • Checkerboard patterns are easiest to work using intarsia, where you carry each color only in the section where it appears, keeping the back of the fabric flat.
  • Plan your pattern on graph paper before you start, marking which stitches are color A and which are color B for every row.
  • Each square should be the same width and height in stitches to look like an actual checkerboard rather than rectangles.
  • Twist the yarns around each other where colors meet to prevent holes from forming between the color blocks.
  • Practice on a small swatch first—a 2-by-2 checkerboard of 10-stitch squares—before committing to a full project.

Plan Your Pattern on Graph Paper Before Casting On

Start by deciding how many squares you want across and down. A 4-by-4 checkerboard (16 squares total) is a good beginner size. Next, choose how many stitches wide each square will be—8 to 12 stitches is standard and keeps the squares roughly square-shaped when knitted. Write this down: if each square is 10 stitches wide and you want 4 squares across, you'll cast on 40 stitches.

On graph paper, draw your checkerboard grid and color in the squares with two colors (or mark them A and B). This becomes your pattern map. Number every row on the left side so you can track which row you're on as you knit. This step takes 10 minutes and prevents mistakes that would take an hour to fix later.

Cast On and Begin With Stockinette Stitch

Cast on the total number of stitches you calculated. For a 4-by-4 checkerboard of 10-stitch squares, cast on 40 stitches using your preferred method. Knit the first row (right side) in your first color, then purl the second row (wrong side) in the same color. This establishes stockinette stitch and gives you a clean edge to work from.

On row 3, you'll begin the color pattern. Look at your graph paper and see which squares appear in row 3. If the pattern calls for color A for stitches 1–10, color B for stitches 11–20, and color A for stitches 21–30, you'll knit exactly that sequence. The key is following your map row by row without skipping or misreading.

Switch Colors and Twist Yarns to Prevent Holes

When you reach the point where the color changes (say, stitch 11), drop the first color and pick up the second. Before you knit the first stitch in the new color, twist the two yarns around each other—wrap the new color around the old color once, then knit. This twist locks the yarns together and closes the gap that would otherwise appear between the color blocks.

Do this twist every time you switch colors, whether you're moving from color A to color B or back again. The twist takes one second and is the difference between a finished checkerboard and one full of small holes. On the purl side (wrong side rows), twist the same way before you purl the first stitch in the new color.

Keep both yarns to the left of your work as you knit. Some knitters pin the yarn balls to a cushion or use yarn bobbins (small spools that hold a length of yarn) to keep them from tangling. Untangle every few rows if needed—it's faster than ripping back.

Work Each Square to the Correct Height

Continue knitting and purling in stockinette, following your graph paper pattern and switching colors as marked. Each square should be worked for the same number of rows as it is wide in stitches. If each square is 10 stitches wide, work 10 rows per square. This keeps the squares roughly square-shaped rather than stretched or squashed.

Count your rows carefully. Use a row counter (a small device that clips to your needle) or mark every 10th row on your graph with a highlighter. It's straightforward to lose count after 20 or 30 rows, and miscounting means your squares won't line up.

Bind Off and Block Your Finished Piece

Once you've completed all your rows, bind off all stitches in the color of the final row. Use a standard bind-off: knit two stitches, pass the first stitch over the second, knit one more, pass the first over the second, and repeat until one stitch remains. Cut the yarn and pull it through the final stitch to find it.

Wet-block your checkerboard to even out the stitches and flatten the color transitions. Soak the finished piece in cool water with a gentle wool wash for 15 minutes, squeeze out excess water gently (do not wring), and lay it flat on a towel to dry. Pin the corners to the towel if you want to set the dimensions. Blocking takes 24 hours but makes the checkerboard look polished and professional.

Common Mistakes and How to Avoid Them

The most frequent error is forgetting to twist the yarns where colors meet, which leaves visible holes. The second is miscounting stitches or rows, which throws off the square alignment. The third is carrying yarn too tightly on the wrong side, which puckers the fabric. Carry yarn at the same tension as your regular knitting—not tight, not loose.

If you knit a stitch in the wrong color, you have two options: drop down and fix it (unravel that stitch and the ones above it, then pick them back up with the correct color), or keep going and use duplicate stitch to cover the mistake after binding off. Duplicate stitch is a way of embroidering over a knitted stitch with the correct color yarn—it's invisible from the front and takes 30 seconds per stitch.

Frequently Asked Questions

Can I use stranded colorwork instead of intarsia for a checkerboard?

Yes, but it's harder for beginners. Stranded colorwork means carrying both colors across every row, even the parts where you don't use them. This works for small patterns but makes the back of the fabric thick and bumpy for large checkerboards. Intarsia (using separate yarn lengths for each color block) keeps the back flat and is the standard choice for checkerboards.

What if I run out of yarn in the middle of a square?

Join a new length of the same color by tying a knot at the edge of your work, leaving 6-inch tails to weave in later. Tie the knot on the wrong side so it doesn't show. If you're in the middle of a row, tie it at the edge of a color block where the knot will be hidden by the twist where colors meet.

How do I know if my squares are actually square?

Measure the width and height of one finished square in inches. They should be close to equal—if a square is 1.5 inches wide but 2 inches tall, your rows are taller than your stitches are wide. This is normal in knitting. To fix it, work fewer rows per square or use a thinner yarn and smaller needles.

Do I need to use bobbins for intarsia?

Bobbins are helpful but not required. They're small spools that hold a length of yarn and prevent tangling when you have many color changes. For a straightforward checkerboard with only two colors, you can manage with just two yarn balls. Bobbins become essential for patterns with four or more colors.

Can I make a checkerboard pattern in the round on circular needles?

Yes, but it's more complex because you can't purl on the wrong side—you knit every round. This means your pattern map changes: you'll knit every row instead of alternating knit and purl. The color-switching technique stays the same. Start with a flat checkerboard before attempting one in the round.
