Jewelry Techniques for Getting a Uniform Polymer Clay Bead Size

Measuring Same Size Bead

Two Methods for Making A Set of Beads That Are All Exactly The Same Size:

According to several recent comments, one common challenge you face is making polymer clay beads of a uniform shape and size. At first I was surprised by this… since one of the free videos you received when you first subscribed to my Polymer Clay Newsletter, addresses this very issue. Then I realized that many of you may not even be on the Polymer Clay Tutor Guest List. Or perhaps it’s because you saw the video so long ago that you have forgotten the information in it.

So I thought I would do a quick review of how to make your polymer clay beads all the same size and point you in the right direction for more information on the subject.

First of all, the only way to make beads all the same size is to start with the same amount of clay. This is very tricky to do by eye as many of you have already figured out.

To easily and accurately measure out the same sized amounts of clay, I like to do it in two different ways.

The first method is to start with an evenly rolled log of polymer clay and divide it into equal sized lengths. A rubber flexible ruler with raised markings often used in schools, is a cheap and accurate way to get perfectly spaced markings on the clay log. Just press the raised measurement lines that are on the ruler, into the clay and use the little dents as guides for cutting. You might cut your pieces at every 1/4 inch mark or every 1/8th mark and so on, depending on the size you want your beads to be. Once these log slices are rolled into their bead shape, they will each be the same size.

Another way to measure out equal amount of clay is with a pasta machine and a cookie cutter. Roll out a sheet of clay and use a cookie cutter to cut out pieces of equal sized clay. You can vary the amount of clay you get by either changing the thickness of the sheet of clay, or the size of the cutter. The cutter shape doesn’t matter since the clay will be formed into whatever bead you are making. Just use the same cutter at the same thickness and the beads will be all the same size.

As with all the polymer clay techniques I teach you, they are often much easier to understand when they are seen in a video. For that reason I have been putting together a library of polymer clay tutorial videos that will really help you with the learning process.

If you would like to see the video I created of the technique I just described you will need to make sure and get signed up on the Polymer Clay Tutor Guest List. You can also watch a introduction preview video here: Making Polymer Clay Beads All the Same Size

I hope this helps you guys out. If you have any more questions on how to make even sized polymer clay beads, make sure to ask below… I am here to help!

    If you aren’t on the Polymer Clay Tutor Guest List and receiving the weekly Video Newsletter, and don’t plan on signing up, can you tell me why? It is as important for me to know why you haven’t joined as much as why you have joined in order to provide the best possible information service to all of you here as beads and beading readers.

    Hey Cindy,

    I have bought most of the items needed to do this, but I can not find the small round cutters you are using to keep the beads uniform in size. Can you suggest where to find them.

    Thanks,
    Denise Hanson

    Hi Denise – The cutters I use are called Polycutters made by Amaco. My set included a diamond shape, 3 graduated ovals and 4 graduated circle cutters. The circles are 15mm, 11mm, 8mm and 6mm. Sometimes they have them in the Makins Air Dry clay section rather than the polymer clay section in Michaels.

    Perfect thanks!

    Thank you so much, this was really informative. I was wondering how to make my beads all the same size without having more equipment.

    Thanks Again!
    Sarah

    You are very welcome Sarah. Glad that helped.

    Hi Cindy, I’ve searched the internet to find the type of ruler you refer to in this video, the flexible ruler with raised markings. No one seems to sell it in the UK, and US shipping to England is exhorbitant, but as I’m about to visit San Francisco in the next few days I wondered if somewhere like Michaels might sell it. Many thanks!

    I’ve been looking for Weldbond since you first recommended it way back. The only place I saw it was at Amazon. Being a Canadian product, our Walmart does not carry it. Good news, I found it today at Michaels. Anxious to give it a try.

  9. Marion R, 22 March, 2011

    Just in case anyone else in the UK is trying to find a flexible ruler with raised markings, you can get one here: rnib.org.uk/shop (they supply things for the blind, hence the raised markings). Ordered one this morning, a little over £4 incl VAT + P&P, consider it a bargain and they were very helpful too!

    @Marion R: Thank you, that’s fantastic! What a good idea, looking on the RNIB site.

  11. Cindy Lietz, 23 March, 2011

    @Janet A: That is excellent news Janet! A long time back when I first talked about Weldbond Glue, I did check online to see if Walmart carried it in the states like they do here in Canada. They did at the time, but if they don’t now I am happy to hear you found it in Michaels.

    @Marion R: Thanks for letting us know about that resource Marion! I checked and the CNIB which is the Canadian National Institute for the Blind also carries a raised marking ruler for about $5. I would imagine most countries would have a similar service. Another option to these rulers is to get a PolyRuler by Amaco or the Marxit by Kato. Both have raised markings on them in a variety of different increments. They are more expensive than the rulers but probably easier to find.

    How do I roll out the clay evenly. Please help

  13. Cindy Lietz, 20 February, 2018

    The easiest way to roll out even sheets of polymer clay is to use a pasta machine.

  14. Kalpana Sriram, 30 March, 2018

    Is there another way to roll the clay evenly? If not, can you please guide me on which machine I should get as I don’t have one and I live in India, I could see several varieties of pasta making machines in the market and I have no idea which one is the right one
