Bead Size Chart

Quick Bead Size Guesstimator:

Bead sizes are usually stated in millimeters (mm).
25.4mm is 1 inch, so....

6mm is about 1/4 inch.
12mm is about a 1/2 inch.
18mm is dime size.

Our bead samples below are shown in relation to a dime.

4. How can I use these bead sizes to plan my jewelry designs?

How many beads will I need for an 8" bracelet?

Bead Size (mm) ~ amount needed for 8" (large wrist ) bracelet
2mm 100
3mm 65
4mm 50
6mm 33

10mm 20
12mm 17

Use these numbers to calculate your bead needs:
For a 8" bracelet (large wrist), using 10mm beads,
you will need 20 beads. You will need LESS if you're also adding spacers or other accents.

How many beads in a 16" strand?

2mm 200
3mm 130
4mm 100
6mm 65
8mm 50

How to calculate Seed Bead sizes:

Seed beads sizes are stated in aughts, (not millimeters) ~ as strung beads per 20 mm or 3/4 inch length.

The higher the number, the smaller the bead.

We've converted aughts to millimeters, large to small:

1 /0=   6.5mm
2 /0=   6.0mm
3 /0=   5.5mm (pony beads, crow, roller)
4 /0=   5.0mm
5 /0=   4.5mm
6 /0=   4.0mm (popular "e" bead)
7 /0=   3.4mm
8 /0= 3.1mm
9 /0=  2.7mm
10 /0= 2.3mm
11 /0= 2.1mm
12 /0= 1.9mm
13 /0= 1.7mm
14 /0= 1.6mm
15 /0= 1.5mm
16 /0= 1.3mm
17 /0= 1.2mm
18 /0=1.1mm
20 /0=1.0mm

3/0 beads
would be 4 per inch,
about 1/4 inch thick each.
(Crow rollers, pony beads)

6/0 beads would be about 8 per inch,
or 1/8 inch thick each.
(The popular "e" bead)

15/0 beads would be 18 per inch,
1/18 inch thick each. (Tiny)

Just remember, the higher the number, the smaller the bead!

This is a general guideline - seed bead sizes are still a little tricky,
even for me sometimes!
