Size Guide

Not sure which size to order? Use this guide to find the right fit for clothing, robes, rings and gloves. If you’re still unsure, just ask — we’re happy to help.

Adult clothing

Most Harry Potter robes, cosplay costumes and licensed clothing use the unisex sizing below. Where a product specifies men’s or women’s sizing, use the relevant column.

Size	Women’s (EU)	Men’s (EU)	Chest (cm)	Waist (cm)
XS	32–34	40–42	80–84	60–64
S	36–38	44–46	84–88	64–68
M	40–42	48–50	88–96	68–76
L	44–46	52–54	96–104	76–84
XL	48–50	56–58	104–112	84–92
XXL	52–54	60–62	112–120	92–100
XXXL	56–58	64–66	120–128	100–108

One size fits all — unless stated otherwise, “one size” corresponds to a women’s M (EU 38–40) or men’s L (EU 52–54). Robes and costumes marked “one size” are typically cut generously and include an adjustable tie or belt.

Children’s clothing

Children’s Harry Potter robes and costumes are sized by height. T-shirts and casual wear may use a slightly different scale — check the individual product page for details.

Size (costumes)	Size (T-shirts)	Height (cm)	Age (approx.)
XS	XS	86–98	1–3
S	XS–S	104–110	3–5
M	S–M	116–128	5–9
L	M–L	140–152	9–12
XL	L–XL	164–176	12–16

Rings & gloves

Use a flexible tape measure or a piece of string to measure your finger circumference (rings) or hand circumference (gloves) before ordering.

Inner circumference (mm)	Diameter (mm)	US	UK
50	15.9	5	—
52	16.6	6	L
55	17.5	7	N
57	18.1	8	—
58	18.5	—	Q
60	19.1	9	—
63	20.0	10	—
65	20.7	11	—
66	21.0	—	W
68	21.6	12	—

Size	US/UK	Hand length (cm)
XS	4	16–17
S	5–6	17–19
M	7–8	19–21
L	9	21–22
XL	10–12	23–25

Ring tip: wrap a piece of string around your finger, mark where it meets and measure the length in mm — that’s your inner circumference. Glove tip: measure the circumference of your hand across the knuckles, without the thumb.
