Chain link is bought by the kilo, the square foot and the roll. Here is the weight of every IS 2721:2003 mesh and wire size, the formula behind it, and a calculator for your own fence.
The common 50 × 50 mm × 10 gauge (3.15 mm) GI chain link weighs about 2.30 kg/m² (0.214 kg/sq ft). In 8 gauge (4.00 mm) it is about 3.65 kg/m²; in 12 gauge (2.50 mm), about 1.47 kg/m².
Fabric only: weight = 2 × wire weight per metre ÷ (mesh + wire). Line wires, posts and fittings are extra; PVC at 1.35 g/cm³.

Chain link is a mesh of diamonds. Each diamond, with a pitch of mesh + wire diameter, owns two sides of wire, so a square metre holds 2 ÷ pitch metres of wire. Multiply by the wire’s weight per metre (0.785 × d² × 7.85 g/m for steel, d in mm):
kg/m² = 2 × 0.00617 × d² ÷ ((mesh + d) ÷ 1000)
The helix adds a few percent; line wires (two up to 2 m wide, three above, per IS 2721) and posts are extra.
| Gauge (SWG) | Diameter (mm, IS 2721 size) |
|---|---|
| 14 | 2.00 |
| 12 | 2.50 |
| 10 | 3.15 |
| 8 | 4.00 |

For 50 mm mesh: about 0.136 kg/sq ft in 12 gauge, 0.214 in 10 gauge and 0.339 in 8 gauge, fabric only.
kg per square metre = 2 × wire weight per metre ÷ (mesh + wire diameter in metres). Then multiply by the fence area and add the line wires.
10 SWG is about 3.25 mm; IS 2721 uses 3.15 mm wire for it.
