Complete Peaky Blinders Cap Size Guide

How to Measure Your Head for a Perfect Fit


Follow these simple steps to get your accurate head circumference and find your ideal cap size:

  1. Wrap a soft cloth measuring tape around your head, positioning it just above your eyebrows and top of your ears.
  2. Keep the tape comfortably snug — not too tight, not loose.
  3. Record your measurement. Repeat 2–3 times, and use the largest reading for accuracy.
  4. No measuring tape? Use a piece of string first, mark the length, then lay it flat against a ruler to measure.
