Raglan Sweater Calculator

Split a raglan neckline into back, front and sleeves — and count the increase rounds.

Back 27, R1, Sleeve 11, R1, Front 27, R1, Sleeve 11, R1 (R = raglan line)

Increase 8 sts every other round × 37 → body 202 sts (front + back)

At least 206 sts around — the body plus the four raglan lines, which are worn stitches too. Your finished chest is wider still: the underarm cast-on (usually an inch or two each side) is added when you join the body.

At the underarm: Back 101, Front 101, each Sleeve 85 sts

Divide the neck into back 27, front 27, and each sleeve 11 sts, then increase 8 sts every other round 37 times to a 202-st body.
Taper each sleeve (before underarm pickup)

How to use

  1. Enter your neck cast-on stitch count and how many stitches each raglan line is (1 is common).
  2. Choose a neck division: Balanced makes front and back equal; Lower front neck puts a few more stitches in the back for a higher front.
  3. Read the four section counts and the marker setup round — Back, raglan, Sleeve, raglan, Front, raglan, Sleeve, raglan.
  4. Enter a target chest stitch count to see how many raglan-increase rounds (8 stitches each) get you there.

Good to know

  • A raglan increase round adds 8 stitches — one on each side of all four raglan lines — so back, front and both sleeves each grow by 2 stitches per round.
  • Neck division varies by design and desired fit; these two presets are sensible starting points, not a substitute for trying the yoke on as you go.
  • The target-chest figure counts the body (front + back) stitches at the point the sleeves separate. Your finished chest is a little wider than that: the raglan-line stitches and the underarm cast-on (usually an inch or two each side) are added when you join the body. Sleeves are increased at the same time and separated at the underarm.

FAQ

How many stitches does a raglan increase round add?
Eight — two at each of the four raglan lines. Back, front and each sleeve gain two stitches every increase round, which is usually every other (right-side) round.
Should front and back be the same?
For a simple pullover, equal front and back (the Balanced preset) works well. For a higher front neck, the Lower front preset shifts a few stitches to the back. Shaped necklines use short rows on top of this.
Is this a full pattern?
No — it is a planning calculator. It gives you the neck division, marker placement and increase-round count. Fit details like neck shaping and underarm cast-on still come from your pattern or your own try-ons.
Does this work for crochet?
Yes — top-down raglan yokes are commonly crocheted. Read each raglan "line" as your increase column; the neck division and the 8-stitches-per-round increase work the same way.
