Good morning,

Does anyone know where I can locate a chart which tells me if I want

a 16" necklace with all 3mm beads, how many beads I need?

I use to have one and I know RIO use to have one in their catalogue

but of course now that one is needed, I can not locate either.

Thank you,

Laurie

Hi Laurie,

Why worry about a chart, figure it out for yourself. One inch is

25.4 mm. A 16" necklace is 406.4 mm (25.4 x 16 = 406.4). 406.4 mm

divided by 3 = 135.46.

Assuming the necklace isn’t knotted & the beads are touching each

other the 135 number is correct If the necklace is knotted, then you

have to add the length of the knot to the equation. Probably about 1

mm per bead.

To determine the number of mm in an item measured in inches,

multiply the inches by 25.4. If you have an item quoted in mm & want

to convert to inches, multiply the mm by .03937 (1 divided by 25.4).

406.4 x …03937 = 16.

No, but this is why you took arithmatic in school! 1 inch=25.4mm.

Multiply 25.4 by 16 to get 406.4 (the length of your necklace in mm).

Divide by 3 (the size of your bead) to get 135.47, and that’s the

number of beads you need. Come on, people, this isn’t rocket

surgery!!

Hello Orchidland,

When figuring out the number of beads necessary for a given length,

don’t forget that the inner diameter (ID) of the strung beads should

be taken into account. This is especially true for larger diameter

beads.

The original question dealt with 3mm beads - so the ID is not a

great concern. However, if using 8 or 10 mm beads for a 15 - 16 inch

choker, that ID might be too close-fitting… a true choker!

seedlings. I wonder what else they’ll attack.

Don’t forget to allow for the catch, or you might get a 17"

neckace,

Hi, Laurie,

Or, you can just lay out a strand of 3mm beads and see how many are

in an inch. If it is a half bead, then 2, or 3 inches.

All the best,

Hi Laurie–Here is a chart I found somewhere-I think it was on a

beading site

'Number of round beads needed for common strand lengths (unknotted):

Bead Size 16" 20" 24" 36"

3mm 130 170 200 300

4mm 100 127 150 225

6mm 67 85 100 150

8mm 50 63 75 113

10mm 40 50 60 90

Hope it’s correct and hope it helps!
