To determine hand size for a knitted glove pattern, start by measuring the circumference of the widest part of your hand, usually around the knuckles, excluding the thumb. Next, measure the length from the base of your palm to the tip of your middle finger to get the glove’s length. It’s also helpful to measure the circumference around the wrist and the length from the wrist to the base of the fingers for a better fit. Compare these measurements to the gauge of your yarn and needles to adjust your stitch count and row numbers accordingly. Taking accurate measurements ensures the glove will fit comfortably without being too tight or loose.
