How many strands should I buy for 10, 20 or 30 students?
Use this rule for common 4, 6, 8 and 10 mm gemstone beads: two bracelets per 15 to 16 inch strand once you allow 8 to 10 percent waste. That assumes mixed wrist sizes and a clasp. If you teach stretch, the plan still holds for 6 and 8 mm.
- 10 students: about 5 strands per design or bead size
- 20 students: about 10 strands
- 30 students: about 15 strands
- Add an extra strand per bead size for flexibility
How many 4 to 10 mm beads do I need per bracelet?
Finished bracelets with a clasp bead the center segment only. Allow about 1.5 inches for clasp and findings, then use beads per inch to size by wrist. Counts below come from our class sheets and round to whole beads.
Use these as a pull sheet on class day. We keep a small tray of 4 mm spacers nearby to fine tune length without redoing the whole layout.
- 4 mm beads, clasped: about 35 beads at 7 in, 38 at 7.5 in
- 6 mm beads, clasped: about 23 at 7 in, 25 at 7.5 in
- 8 mm beads, clasped: about 17 at 7 in, 19 at 7.5 in
- 10 mm beads, clasped: about 14 at 7 in, 15 at 7.5 in
How many bracelets come from one strand?
Rondelles are the workhorse shape for bracelet classes. A 15 to 16 inch strand of 6 mm rondelles has about 65 to 70 beads, 8 mm about 48 to 52, and 4 mm about 95 to 100. Using the counts above and 8 to 10 percent waste, plan two bracelets per strand for mixed wrists.
For 10 mm, a 16 inch strand carries about 40 beads, which also yields two bracelets for mixed wrists. If your strands arrive on the shorter 13 inch length, expect fewer bracelets. See our notes on rondelles for why they string fast and consistently.
Should I plan differently for stretch or clasped bracelets?
Stretch uses the full wrist length, so it needs more beads than a clasped build of the same finished length. A 7 inch stretch needs about 29 beads in 6 mm or about 22 beads in 8 mm, which still tracks to two bracelets per strand with waste included.
Clasped bracelets need fewer beads because the clasp covers length. If students mix bead sizes, treat the largest size as the driver, and fill with small spacers to hit exact length. Tradition calls clear quartz the universal spacer; see our crystal quartz guide for ideas.
Which bead shapes string fastest in class?
Rondelles and heishi are our go to for smooth class builds. They seat neatly and read as a continuous band on the wrist. Learn their dimensions on our pages for rondelles and heishi.
Statement shapes work as focals with rondelles as the body. Hearts, pears and pyramids add an accent without shifting your math much. Browse current strands on the shop and match them to the counts above.
Where can I see strands and plan in person?
We sell by the strand online and at InterGem. See our upcoming shows at the schedule. Bring your syllabus and we will help you chart bead counts by wrist on the spot.
