Why shape shoulders in steps?

Binding off all shoulder stitches at once creates a stair-step edge. Shaping in 3 or more groups creates a smoother, sloped shoulder line that is easier to seam and looks more professional.

What is the difference between bind-off and short-row shoulders?

Bind-off shaping creates small steps. Short-row shaping creates a smooth slope by turning the work progressively earlier. Short rows give a neater finish and work well for grafting or three-needle bind-off.

How many groups should I divide shoulders into?

Three groups is standard for most garments. For very wide shoulders or fine-gauge knitting, four groups gives an even smoother line. Two groups is acceptable for chunky knits.

Do front and back shoulders match?

Yes, front and back shoulders should have the same number of stitches and the same shaping. The only difference is in the neckline: the front neck is deeper, so the front shoulders start shaping sooner.

How do I join shaped shoulders?

Use mattress stitch, three-needle bind-off, or grafting (Kitchener stitch). Three-needle bind-off is popular because it is quick, creates a neat seam, and works well with stepped shaping. Short-row shoulders are ideal for grafting.

How We Calculate This

This calculator divides shoulder stitches into equal groups for stepped shaping.

The formula

Stitches per group = Shoulder stitches / 3

Any remainder stitches are added to the first group(s) for a smooth slope.
