Getting an exact number
Work a swatch in your yarn and stitch, weigh it, and scale up: project area ÷ swatch area × swatch weight gives the grams, and the skein label turns grams into yards. The yarn calculator does this for you.
Buy all the skeins at once from the same dye lot, and plan about 10 % extra for edging, seams and joining.
Estimates from the StitchTick yarn calculator: fabric area × typical yards per square inch for each yarn weight and stitch (Craft Yarn Council wraps per inch). Stitch pattern, hook and tension can change them by 15–20 % either way.
