✨ Ultimate Guide to Bead Sizes and Making Beautiful Beaded Pens

June 14, 2025

Making beaded pens is a fun and creative craft! To ensure your beads fit perfectly and your pen is functional and beautiful, here’s a detailed guide on choosing bead sizes, spacers, materials, and must-have tools.


🖊️ What Size Beads Fit on Pens?

How Do I Know What Size Beads to Get?

The two most important measurements are:

  • Inner Diameter (Hole Size)
    Most beadable pen blanks feature a metal shank that is 2mm to 3mm thick. Therefore, your beads must have a hole size of at least 2.5mm to slide smoothly.
  • Outer Diameter (Bead Size)
    The bead diameter defines the style:
    • 6–8mm: Slim and elegant.
    • 8–10mm: Popular and balanced look.
    • 10–12mm+: Bold, statement designs.
    • The first bead near the tip is often 12mm or larger to align well with the pen’s base.
