How to Calculate Decreases for a Raglan?

A raglan typically decreases 4 stitches per decrease row — one at each of the four raglan seam lines (two front, two back, or however your specific construction splits them) — repeated at a regular interval until the shoulder shaping is complete.

A real worked example

Reducing 200 stitches to 120 stitches (an 80-stitch total reduction) across 20 decrease rows works out to exactly 4 stitches removed per row throughout — a clean, evenly spaced sequence with no remainder to distribute unevenly. Not every raglan reduction lands this cleanly; a real pattern's numbers might need a few rows carrying one more decrease than others.

Why raglan angle depends on decrease frequency, not just total count

The same total stitch reduction, spread across more rows (worked less frequently — every 3rd row instead of every row, for instance), produces a shallower, longer raglan line; spread across fewer rows, it produces a steeper, shorter one. Two raglans reducing the identical 80 stitches can look completely different in shape purely from how the decreases are spaced across the available rows.

Adjusting a raglan for a different total stitch reduction

If your own total reduction differs from a pattern's original numbers (a different gauge or size), the Stitch & Row Spacer generates the actual decrease-row instructions — including how any remainder gets distributed across the sequence — for your specific starting and ending stitch counts.

FAQ

Does every raglan decrease exactly 4 stitches per decrease row? Most do, since 4 seam lines is the standard raglan construction, but some raglan variations decrease at additional points (an extra decrease at the center front or back, for instance) for a different resulting shape — check the specific pattern's construction rather than assuming 4 always applies.

Should raglan decreases happen every row or every other row? Depends entirely on the desired angle and how many total rows are available for the shaping — a pattern's stated decrease frequency is a deliberate design choice, not an arbitrary default, and changing it changes the finished raglan line's steepness.

Is raglan shaping worked the same way in crochet as in knitting? The general principle (regular decreases at seam lines building a diagonal shaping line) carries over, though the specific decrease stitches and exact mechanics differ between the two crafts.

Does a raglan need identical decrease counts on the sleeve and body sides of each seam? Not necessarily — some raglan designs intentionally decrease the body and sleeve at different rates for a specific fit, though a symmetrical, equal-rate raglan is the more common default most patterns use.
