Size Guide
Find Your Perfect Fit.
Every Marcelia piece is one size, with an adjustable fit that suits most head shapes. Use the chart below to check your head circumference.
Headwear — One Size, Adjustable
| Size | Head Circumference (cm) | Head Circumference (in) | Fitted Equivalent |
|---|---|---|---|
| S / M | 54 – 57 | 21¼ – 22½ | 6⅞ – 7⅛ |
| One Size | 55 – 61 | 21⅝ – 24 | 7 – 7⅝ |
| L / XL | 58 – 61 | 22¾ – 24 | 7¼ – 7⅝ |
One size fits most: Every Marcelia piece is designed as one size, with a snapback, strapback, or elastic fit that adjusts comfortably across head circumferences from roughly 54–61 cm. Beanies and knit styles stretch to conform. Fitted-style caps sit best at the mid-point of the range — if you're at the very top of the scale, choose a snapback or strapback for the most comfortable fit.
Measure Your Head
Step 01
Gather what you need
A soft tape measure works best. No tape? Use a piece of string and a ruler.
Step 02
Position the tape
Wrap it around the widest part of your head — about 1 cm above your ears and mid-forehead, where a cap naturally sits.
Step 03
Read the measurement
Keep the tape snug but not tight. Note the circumference in centimetres. Using string? Mark it and measure against a ruler.
Step 04
Match your fit
Compare your measurement to the chart. Almost every head falls within our adjustable one-size range, so you're covered.
Tip: Measure over the hairstyle you usually wear, and keep the tape level all the way around for the most accurate reading.
