A raglan sweater cannot be sized safely from a single weighted quiz. Front, back, sleeve and neckline proportions depend on the construction and the designer’s shaping.
Count increases explicitly
In a common top-down arrangement with four raglan lines, increasing once on each side of every line adds eight stitches on that increase round. Ten such rounds add 80 stitches. This does not say that ten rounds fit your body: neckline shaping and pattern-specific increases can change the total.
Track front, back and each sleeve separately. Account for raglan-line stitches, cast-on stitches at the underarm and any short rows. Check both yoke depth and circumference before dividing the sleeves. A correct total can still give sleeves that are too narrow.
Use the pattern’s schematic and a washed gauge swatch. If changing gauge or garment size substantially, work from a tested pattern in the desired range rather than assigning percentages to body sections. Our needle-size guide covers the gauge step.
