How this service works
Number of beads for a strand of a given finished length from bead size and spacing, with finished length and total weight.
Output
Returns the number of beads needed for the strand, the pitch (center-to-center spacing in mm), beads per inch, usable strand length in mm, finished length in both mm and inches, how far the strand falls short or over the target, total weight in grams (if gramsPerBead is supplied), a plain-English summary, and edge-case notes or warnings.
Example use cases
Buying beads for a princess necklace
“I want to make a 18-inch necklace using 6mm round beads with no spacers and a 12mm clasp — how many beads do I need to buy?”
Knotted pearl strand planning
“I'm stringing a 16-inch pearl necklace with 7mm pearls and 1.5mm knots between each pearl with a 20mm clasp. How many pearls do I need and what will the finished strand weigh if each pearl is 0.3 grams?”
Bulk bead order for a 45cm beaded rope
“I need to make a 45cm strand using 4mm beads with 0.5mm wire loops between each bead. Can you tell me the bead count and beads-per-inch so I can place a bulk order?”
Technical details
Endpoint
GEThttps://jewelry-calc.x402tookit.com/bead-count?utm_source=zero.xyzWhen to prefer
Use this endpoint when a user needs to plan a beaded jewelry strand and wants to know exactly how many beads to buy or prepare, optionally accounting for spacing elements (knots, wire loops, spacers) and clasp length. Prefer this over generic arithmetic when the user wants a jewelry-specific breakdown including beads-per-inch, pitch, and total weight in one call.
Side effects
- Missing required beadMm parameter returns an error
- Neither lengthInches nor lengthCm provided causes missing input error
- Bead diameter larger than finished length returns a zero or error result
- Negative or zero values for bead size or length produce invalid computation
- Very large bead diameters relative to strand length may return 1 or 0 beads with a warning
