Yarn Stash Calculator — Stash Length and Value

Sort by yarn weight (lace, fingering, DK, aran, chunky), then by fibre type or colour. Store in clear bins or bags away from sunlight, moths, and moisture. Keep a digital inventory with weight, yardage, colour, and dye lot for each yarn. Ravelry's stash tool is popular for this.

Use cedar blocks or lavender sachets in storage. Wash yarn before storing (moths are attracted to skin oils and food residue). Seal yarn in airtight bags or containers. Check regularly for signs of damage. Freeze suspect yarn for 72 hours to kill larvae.

Yes, for insurance purposes and to understand your investment. Many knitters are surprised by the total value. It also helps prioritise using expensive yarns rather than hoarding them, and justifies yarn purchases when you can show you use what you buy.

This depends on yarn weights and project types. A hat uses ~100-180m, a scarf ~200-400m, a pair of socks ~350-450m, and a sweater ~800-1500m. Divide your total length by the average project size for a rough count. This calculator uses 800m as a mid-range estimate.

If you have had yarn for years with no project in mind, consider destashing through Ravelry sales, knitting group swaps, or charity donation. Someone else will use and appreciate it. This also makes room for yarn you are genuinely excited about.
