A checkerboard pattern uses two colors and straightforward knit-purl combinations

A checkerboard pattern in knitting is made by alternating knit and purl stitches in a grid. You work in blocks: a few stitches of knit, then a few stitches of purl, then back to knit. When you move to the next row, you reverse the pattern—purl where you knitted before, knit where you purled. After a few rows, the squares appear. It looks complicated but uses only two basic stitches you already know.

The pattern works best on a flat piece like a dishcloth, baby blanket, or scarf. You need two colors of yarn, though one color works too—the texture alone creates the checkerboard effect. Most beginners start with a 4-stitch or 6-stitch block size, which means knitting 4 or 6 stitches, then purling 4 or 6 stitches, then repeating across the row.

Key Takeaways

  • A checkerboard uses only knit and purl stitches arranged in alternating blocks of 4 to 6 stitches each.
  • Each row reverses the previous row's pattern—if you knitted a block, you purl it in the next row.
  • Changing yarn color every two rows makes the checkerboard more visible, though it is not required.
  • The pattern repeats every 8 to 12 rows, so once you complete one full cycle, you can continue or bind off.

Cast on a multiple of your block size

Start by casting on a number of stitches that divides evenly by your block size. If you choose a 4-stitch block, cast on 16, 20, 24, or 28 stitches. If you choose a 6-stitch block, cast on 18, 24, or 30 stitches. A larger cast-on creates a bigger checkerboard; a smaller one is faster to finish and easier to practice on.

For a beginner, 20 stitches with a 4-stitch block is a good starting point. It takes about 10 minutes to cast on and gives you five blocks across, which is enough to see the pattern clearly without spending hours on setup.

Work rows 1 and 2: establish the first block row

Row 1: Knit 4 stitches, then purl 4 stitches. Repeat this pattern across the entire row. If you cast on 20 stitches, you will knit 4, purl 4, knit 4, purl 4, knit 4. End with a knit block. Do not cut the yarn.

Row 2: This is where the checkerboard forms. Purl the 4 stitches that you knitted in row 1, then knit the 4 stitches that you purled in row 1. Repeat across. You are reversing the pattern, so purl 4, knit 4, purl 4, knit 4, purl 4.

After row 2, you will see the first hint of the checkerboard texture. The knit blocks sit slightly raised, and the purl blocks sit slightly recessed. This is normal and exactly what you want.

Repeat the pattern for 4 to 6 more rows

Rows 3 and 4 repeat rows 1 and 2 exactly. Row 3 is knit 4, purl 4 across. Row 4 is purl 4, knit 4 across. Continue this cycle for at least 8 rows total (4 pairs of rows). The checkerboard becomes clearer with each pair.

Common mistake: switching the pattern in the middle of a row. If you knit 4 and purl 4 in row 1, do not suddenly knit 3 and purl 5 in row 3. The blocks must stay the same width, or the pattern breaks and looks messy. Count on your fingers if you need to—knit 1, 2, 3, 4, then purl 1, 2, 3, 4.

Another common mistake: forgetting to reverse the pattern on the next row. If row 1 is knit-purl-knit-purl, row 2 must be purl-knit-purl-knit. Write it down on a sticky note if it helps: "Row 1: K4 P4. Row 2: P4 K4. Repeat."

Change yarn color every two rows for a clearer checkerboard

If you want the checkerboard to stand out more, switch to a contrasting yarn color after every two rows. After you finish row 2, cut the first color (leaving a 4-inch tail), tie on the second color, and knit row 3 in the new color. After row 4, cut the second color and tie on the first color again.

To tie on a new color, make a straightforward knot at the edge of your work. Leave both tails hanging outside the knitting—you will weave them in later. The knots will be hidden in the seam if you sew the piece together, or you can hide them on the back if it is a flat piece.

If you do not want to change colors, the pattern still works. The texture of the knit and purl stitches creates the checkerboard effect on its own, just more subtly. Many knitters prefer a single color for dishcloths or practice pieces.

Bind off when the piece is square or the desired size

A checkerboard looks best when the width and height are roughly equal. If you cast on 20 stitches and each stitch is about 0.2 inches wide, your piece is about 4 inches across. Knit until the piece is also about 4 inches tall—this usually takes 20 to 24 rows. Count your rows by marking every 10 with a stitch marker or pen on paper.

To bind off, knit two stitches, pass the first stitch over the second, knit one more stitch, pass the previous stitch over it, and repeat until one stitch remains. Cut the yarn, pull the tail through the last stitch, and pull tight. Weave in the yarn tails with a tapestry needle.

Troubleshooting common problems

The checkerboard looks lopsided or wavy. This usually means you are pulling the yarn too tight on purl stitches. Purl stitches naturally sit looser than knit stitches, so ease up slightly when you purl. The tension should feel the same for both, even though the stitches look different.

You lost track of which row you are on. Mark your rows with a stitch marker or a piece of scrap yarn. Move it up one row each time you finish. Alternatively, write the row number on a piece of paper and cross it off as you go. This sounds tedious but saves you from frogging (ripping out) an entire section.

One block is wider or narrower than the others. You probably miscounted stitches in that block. If it is only one row off, you can usually live with it—the eye blends small variations. If it is two or more stitches off, frog back to the beginning of that row and recount carefully.

Frequently Asked Questions

Do I have to use two colors?

No. A single color works fine because the knit and purl stitches create texture that reads as a checkerboard. Two colors make it more obvious, especially from a distance, but one color is perfectly valid and often preferred for practice pieces.

What if I mess up a row in the middle?

If you notice the mistake right away, drop down to that row, fix the stitch, and pick it back up. If you do not notice until several rows later, you can frog (rip out) back to the mistake and reknit from there. For a beginner, frogging back 2 to 3 rows is usually faster than trying to fix it in place.

How do I make the checkerboard bigger or smaller?

Use a larger block size (6 or 8 stitches instead of 4) for bigger squares, or a smaller block size (2 or 3 stitches) for smaller squares. Larger blocks are easier to see and less fiddly; smaller blocks look more intricate but require more counting.

Can I use this pattern on a sweater or hat?

Yes, but you need to plan ahead. The checkerboard pattern works best on flat pieces or pieces you knit flat and sew together. If you knit in the round (for a hat or sleeve), the pattern becomes harder to manage because you cannot easily reverse the knit-purl sequence on every other row. Flat pieces are the easiest place to start.

How tight should my tension be?

Aim for medium tension—not so tight that the stitches are hard to work into, and not so loose that you can see gaps between stitches. Purl stitches will naturally look looser than knit stitches, so do not panic if they look different. The tension is correct if the finished piece feels even and the blocks are roughly the same size.
