The Ultimate Guide to How to Decrease Knitting Stitches

Knitting is a creative journey, and learning how to decrease knitting stitches is a crucial skill that takes your projects to the next level. Whether you’re shaping the crown of a hat or adding dimension to a sweater, decreases are vital for crafting polished and well-fitted pieces. Let me walk you through the most common methods, explain when to use them, and give you five free patterns to practice on.

As we dive in, I’ll also share why KnitPicks Reflections needles (affiliate link) are my go-to choice for decreases. These needles feature perfectly tapered tips, making it easy to work with all yarn weights.


What Are Decreases in Knitting?

Decreases reduce the number of stitches on your needle. This creates shaping for projects like sleeves, necklines, hats, and mittens. Mastering how to decrease knitting stitches ensures your finished pieces look professional and fit comfortably.


Common Types of Knitting Decreases

1. K2tog (Knit Two Together)

The K2tog is one of the simplest and most popular decreases. It leans to the right, making it ideal for symmetrical shaping.

  • When to Use: Crown shaping for hats, side decreases for sweaters, or anywhere a subtle decrease is needed.
  • How to Do It: Insert your needle through two stitches as if to knit, then knit them together as one.

2. SSK (Slip, Slip, Knit)

SSK creates a left-leaning decrease. It pairs well with K2tog for balanced shaping.

  • When to Use: Along raglan seams, neckline shaping, or decorative decreases.
  • How to Do It: Slip two stitches knitwise, return them to the left needle, then knit them together through the back loop.

3. P2tog (Purl Two Together)

This is the purl-side equivalent of K2tog, producing a right-leaning decrease.

  • When to Use: Inside ribbing patterns or on the purl side of stockinette stitch.
  • How to Do It: Insert your needle through two stitches as if to purl, then purl them together.

4. SSP (Slip, Slip, Purl)

SSP creates a left-leaning decrease on the purl side.

  • When to Use: Paired with P2tog for mirrored decreases in ribbing or lace.
  • How to Do It: Slip two stitches knitwise, return them to the left needle, and purl them together through the back loop.

5. Centered Double Decrease (CDD) or Vertical Double Decrease

This creates a clean, centered decrease that pulls 3 stitches into one.

  • When to Use: Decorative lace patterns or shaping that requires symmetry.
  • How to Do It: Slip two stitches together knitwise, knit the next stitch, then pass the slipped stitches over the knit stitch.

Pro Tips for Neat Decreases

  1. Tension Matters: Keep your stitches snug but not too tight. This prevents gaps.
  2. Mark Your Decreases: Use stitch markers to track where decreases occur.

Troubleshooting Common Decrease Mistakes

Uneven Decreases

If your decreases look uneven, double-check whether you’re pairing the correct left-leaning and right-leaning methods.

Gaps Around Decreases

Gaps can happen if your tension is too loose. Tighten up the stitches before and after the decrease.

Confusing SSK with K2tog

Remember: SSK leans left, and K2tog leans right. Keeping this distinction in mind will help your projects look polished.
