How many beads does a bead crochet rope need?

A bead crochet rope is one continuous spiral, so a full turn takes the circumference plus half a bead: 6 around means 6.5 beads per turn. Each turn nests hexagonally into the one below and climbs about 87% of a bead diameter. Thickness comes from the ring of beads around the core, circumference × bead spacing ÷ π, plus one bead diameter for the beads themselves. Tension, thread, and hook size change a real rope, so crochet a 5 cm sample before buying beads for a long necklace.

Example: a 45 cm rope, 6 beads around
In Preciosa 10/0 that is about 1,468 beads, roughly 16 g, on a rope about 5.6 mm thick — around 33 beads for every centimetre of finished rope.

Six is the usual circumference for a necklace rope in 10/0 or 11/0 beads. Below five the rope is hard to keep round; 8 to 12 around gives a thicker rope or bangle and needs proportionally more beads.

No. The total depends only on length, circumference, and bead size. Stringing order is what the repeat changes: a rope is strung in one exact sequence, and a repeat that does not divide evenly into the length leaves a partial repeat at the end.

Tight tension, a smaller hook, or thicker thread packs the turns closer together, so the same strung beads make a shorter rope. Crochet 5 cm, measure it, and scale the count from your own sample.
