I am new to beading and am confused by all the sizes of seed beads. Can you tell me how many beads I get in each different size? Seed beads are measured in aughts. This can be confusing as we are used to inches and millimeters as our unit of measure. Aughts are the number of beads lined up side by side in a given space. A 6/0 bead means that you will get 6 beads in the space. 11/0 will be eleven beads in the same amount of space. So the smaller the number the bigger the bead, as it takes fewer beads to fill the space. This chart will help you determine the number of seed beads per inch based on size. Remember that this is approximate as there are differences between manufacturers, country of origin and finishes.
