How many stitches should I cast on for mittens?

Cast-on count depends on your hand circumference and stitch gauge. For a women's medium hand (19.5 cm circumference) in DK weight (22 sts/10cm), you would cast on approximately 40 stitches. The calculator rounds to the nearest multiple of 4 for even distribution across double-pointed needles.

How much ease should mittens have?

Mittens should have slight negative ease (about -5%) so they fit snugly and stay warm. This means making them slightly smaller than the actual hand measurement. The knitted fabric stretches to fit. Too much positive ease lets cold air in, while too much negative ease makes them uncomfortable.

How do I calculate the thumb gusset?

The thumb gusset is typically about 25% of the total stitch count. For 40 cast-on stitches, the thumb would be 10 stitches. Increases for the gusset are made every other round, starting about 2-3 cm above the cuff, until you have enough stitches. These are then placed on waste yarn while you continue the hand.

How much yarn do I need for a pair of mittens?

A pair of women's medium mittens in DK yarn needs approximately 90-100 metres total (45-50 metres per mitten). Aran weight uses slightly less yardage due to fewer stitches, while chunky mittens use the least. Add 10% extra for the cuff and thumb gusset.

How We Calculate This

This calculator uses your hand measurements and gauge to determine cast-on count, thumb sizing, decrease placement and yarn requirements for mittens.

Cast-on calculation

Cast on = (Hand circumference x (1 + Ease%)) / 10 x Stitch gauge

Rounded to the nearest multiple of 4 for even DPN distribution.

Thumb gusset

Thumb stitches = Cast-on count x 25%

Decreases

Crown decreases begin when the mitten reaches fingertip level, working paired decreases at 4 points around the mitten until stitches are reduced to close the top.
