Sweater Size Calculator: No More Baggy Shoulders
This sweater size calculator targets the #1 knitwear complaint: shoulder slouch. Knit fabric stretches differently than woven, so a sweater that 'fits' the chest spec can still droop at the shoulder line. Enter chest, shoulder, and sleeve length to get your size for cashmere, merino, cotton, and chunky-knit sweaters. Use the calculator below to get your exact fit in 30 seconds.

Frequently Asked Questions
Why do my sweaters always sag at the shoulder?
Knit fabric is heavier than woven and lacks structural support at the shoulder seam. Order a brand that publishes shoulder spec, or size down 1 for fitted cashmere.
Should I size up for cardigans or pullovers?
Cardigans match exactly — they're worn open. Pullovers can size down 0.5 if you want a fitted silhouette over a shirt.
How do chunky knits fit differently from fine gauge?
Chunky knits add visual bulk; size to your true measurement, don't size up. Fine-gauge sweaters can be sized down 0.5 for a fitted, tucked look.
What if my sweater is too long in the body?
Cashmere and merino can be hand-blocked shorter; cotton can't. Check the length spec on the product page before ordering, especially for cropped vs regular cuts.
