How to Measure Your Head for a Hat: Complete Sizing Guide

By Eric Javits3 Min Read

To measure your head for a hat, wrap a flexible measuring tape around your head approximately one inch above your ears and across your mid-forehead, keeping the tape snug but not tight. Record the circumference in centimeters or inches, then compare to the brand's size chart. This single measurement is the most important step for ensuring a comfortable, well-fitting hat.

What You Need

  • A soft fabric measuring tape (tailor's tape) — these are inexpensive and the only accurate tool for this measurement
  • A mirror, or ask someone to assist for accuracy
  • Pen and paper to record your measurement

Step-by-Step Measurement Instructions

  1. Position the tape: Start at the widest point of your forehead, approximately one inch above your eyebrows
  2. Wrap around: Take the tape around the sides of your head, above the ears, to the widest part of the back of your head
  3. Check the tension: The tape should be snug — touching the head all the way around — but not tight enough to dent or compress. You should be able to slide one finger underneath.
  4. Read the measurement: Note the circumference where the tape meets the starting point. Record in both centimeters and inches.
  5. Measure twice: Repeat the measurement once to confirm consistency

Understanding Adjustable vs Fixed Size Hats

Many Eric Javits hats — particularly Squishee® styles — feature internal elasticized bands that accommodate a range of head circumferences. These one-size-fits-most hats are ideal for gifting or for buyers between sizes.

  • Fixed size: A precisely sized hat that fits one circumference — look for a stated size (S/M/L or specific cm measurement)
  • Adjustable elastic: A band that stretches to fit multiple sizes — typically 54–60 cm
  • Drawstring: A cord inside the sweatband that can be cinched for a tighter fit

Tips for Online Hat Shopping

  • Always compare your measurement to the brand's own size chart — sizing varies between brands
  • If you are between sizes, size up and rely on an adjustable band
  • Consider the crown height: deeper crowns have more volume; shallower crowns sit closer to the head
  • Read reviews for fit notes, customers often mention whether a style runs large or small
