Here's a comparison of some types of beads I often use.
Bead size is written at the left, with 3 examples of that size in each row (round, faceted, and bicone shapes).
Seed beads are between the lines at the bottom of the picture.
Size 20 thread and finer can fit through the hole of any of these beads.
Size 10 Lizbeth thread is thicker, so the 3 mm beads and some 11/0 seed beads won't fit. I've taken to using Toho Takumi large hole beads when I want an 11/0 seed bead with size 10 thread, since they fit easily. Delicas (a brand of Japanese cylinder beads) will also fit on size 10 thread. They really are shaped like tiny cylinders.
Not on the list are a new arrival called "demi" seed beads. They're half the width of regular seed beads. I tried them on some dainty snowflake earrings in size 40 thread, and liked the delicate effect in the picots combined with a regular 11/0 seed bead on the core thread.

The snowflake pattern is mine, "tweaked" and "upgraded" from a simpler original I blogged about in 2008, Quickie Snowflake Earrings.
