An 8-inch bangle with 2 wraps of 18 gauge gold-filled wire requires about 16 inches (1.3 feet) of wire.
For a simple wire-wrapped ring, multiply the ring circumference by the number of wraps. A size 7 ring with 3 wraps typically needs 6-8 inches of wire. Add 20% extra for shaping and finishing. Thicker gauges (18-20ga) work best for structural rings.
Use 18-20 gauge for rings and structural pieces that need to hold their shape. Use 22-24 gauge for general pendants and earrings. Use 26-28 gauge for fine wire wrapping and decorative details. The project type determines the best gauge selection.
Wire weight depends on the gauge (diameter), length, and material density. Calculate the wire volume using πr²L, then multiply by material density. Sterling silver weighs approximately 10.5 g/cm³, copper 8.9 g/cm³, and gold 19.3 g/cm³.
Sterling silver wire costs vary by gauge and market prices. Generally, 20 gauge costs $3.50-4.00 per foot, 22 gauge $2.50-3.00, and 24 gauge $2.00-2.50. Prices fluctuate with the silver market. Buy in bulk for better rates on larger projects.
Wire gauge measures thickness - smaller numbers mean thicker wire. 18ga (1.02mm) is thick and sturdy for rings, 20ga (0.81mm) is versatile for most projects, 22ga (0.64mm) is good for lightweight pieces, and 24-28ga (0.51-0.32mm) are for fine detail work and wrapping.
A basic wire-wrapped pendant needs the perimeter of the stone or focal piece multiplied by 2-3 wraps, plus 3-6 inches for the bail. A 1x1.5 inch pendant typically requires 15-20 inches of frame wire (20-22ga) plus 24-36 inches of wrapping wire (24-26ga).
