Industry Standard Units

Most Common Units of Measure

The following are units of measure that are used thought the industry.  These convenient measurement are widely used because they easily break down into smaller selling quantities.

  • Mass = 1,200 pieces
  • Gross = 144 Pieces
  • Kilo = 1,000 grams (2.2 pounds)
  • Incremental Breakdown of 1 Mass:
  • 1 mass = 1200 Pieces                           1 X 1200       
  • 1/2 mass = 600 Pieces                          2 X 600         
  • 1/4 mass = 300 pieces                           4 X 300         
  • 1/8 mass = 150 Pieces                           8 X 150        
  • 1/10 mass = 120 Pieces                        10 X 120        
  • One-hundred Dozen = 1200 Pieces     12 X 100        
  • Incremental Breakdown of 1 Gross:
  • 1 gross = 144 Pieces                1 X 144          
  • 1/2 gross = 72 Pieces               2 X 72            
  • 1/12 gross = 1 dozen                12 X 12
  • Incremental Breakdown of 1 Kilo:
  • 1 kilo = 1000 Grams                 1 X 1000      
  • 1/2 kilo = 500 Grams                 2 X 500        
  • 1/4 kilo = 250 Grams                 4 X 250        
  • 1/10 kilo = 100 grams              10 x 100
  • Strung Beads

    Currently, most Czech glass is strung on nylon string to make it easier for our customers to prepare the beads for resale. Some stock is still strung in cotton strand hanks; if the string type is important, please add a preference note when placing orders. The number of beads per hank changes depending on many factors including size, shape and cost.  The following is a general guide to how beads are strung.  Bead stringing may vary depending on the batch or factory of origin. Hank is a broad term used to describe a bundle of strung beads.  They quantity of beads and the number of strands per hank varies between styles and sizes. Below are the number of beads per hank by bead style:

    Pressed Beads
  • 3mm and some 4mm: 12 strands of 100 beads (1 mass)
  • 4mm to 6mm: 12 strands of 50 pieces = 1/2 mass
  • 8mm or larger: 12 strands of 25 pieces = 1/4 mass
  • Fire Polished Beads
  • 3 to 4mm: 12 strands of 50 pieces = 1/2 mass
  • 6mm or larger: 12 strands of 25 pieces = 1/4 mass
  • Bead Quantities per Mass

    The table below shows the typical stringing quantities per minimum order unit for a given item. Please note that not all beads adhere to the typical standard. Items that are not sold by piece and contain beads of varying sizes are usually sold in hanks of 6, 16 inch long strands.
