Single jersey or interlock? The difference that actually matters
Single jersey is knitted on one bed, interlock on two. That one-sentence difference cascades into coverage, edge curl, weight and cost.
Comparison
Single jersey is knitted on one bed, interlock on two. That one-sentence difference cascades into coverage, edge curl, weight and cost.

Single jersey has a different face and reverse; interlock looks the same on both sides. At equal weight interlock covers better, which is why it wins for pale shades and anything worn close to the skin.
Cut single jersey curls at the edge, and that is extra handling in cutting and sewing. Interlock does not curl. When you cost garment yield, that difference can outweigh the price per kilo.
Interlock is usually specified heavier for the same end use: our catalogue runs single jersey at 130–210 g/m² and interlock at 190–280 g/m². Decide on consumption per garment, not price per metre.

Interlock is generally more stable thanks to the double-knit structure, though durability also depends on yarn and finishing.
Single jersey for classic tees; interlock where premium hand or opacity is wanted.
