The Ultimate Anime Cosplay Size Guide
Finding the perfect cosplay costume is about more than simply choosing your usual clothing size. Unlike everyday fashion, cosplay costumes are often produced by specialist manufacturers, many of whom use different measurement standards depending on the country they are made in.
This means that a size Medium from one manufacturer may fit completely differently from a Medium from another. That’s why experienced cosplayers almost always rely on body measurements rather than the size label alone.
At MBCosplay, we want every customer to feel confident when ordering. This guide explains everything you need to know about cosplay sizing, including how to measure yourself correctly, why Asian sizing differs from UK and US clothing, and how to achieve the best possible fit.
Why Cosplay Sizes Are Different
Many anime, gaming and cosplay costumes are manufactured using Asian sizing systems. These sizing standards are typically designed around different average body measurements than standard UK, European or American clothing.
As a result, the size printed on the label should only be used as a reference.
Instead, always compare your personal measurements with the size chart provided on the product page.
Every manufacturer is slightly different, which is why MBCosplay provides a dedicated size guide wherever available.
Why Body Measurements Matter More Than Clothing Size
Your everyday clothing size is influenced by:
● Different fashion brands
● Fabric stretch
● Clothing style
● Personal fit preference
Cosplay costumes are much more structured.
Many include:
● Tailored jackets
● Corsets
● Armour details
● Belts
● Dresses
● Uniforms
● Bodysuits
● Accessories
Choosing based only on “I’m usually a Medium” often leads to disappointment.
Instead, accurate body measurements provide the most reliable fit.
How to Measure Yourself for Cosplay
For the most accurate results, use a soft measuring tape while wearing lightweight clothing.
Avoid pulling the tape too tightly.
Bust
Measure around the fullest part of your bust while keeping the tape level.
Chest
For male costumes, measure around the fullest part of your chest with your arms relaxed.
Waist
Measure your natural waist—the narrowest part of your torso.
Avoid measuring where your jeans usually sit.
Hips
Measure around the fullest part of your hips and bottom.
Shoulder Width
Measure from one shoulder edge to the other across your back.
This measurement is particularly important for military uniforms and fitted jackets.
Height
Stand barefoot against a wall and measure from the floor to the top of your head.
Some costumes are designed with height ranges in mind.
Should You Size Up?
If your measurements fall between two sizes, sizing up is usually the safest option.
This is especially recommended for:
● Non-stretch fabrics
● Military uniforms
● Tailored costumes
● Dresses with zips
● Bodysuits
● Armour costumes
A slightly larger costume is generally easier to alter than one that is too small.
Understanding Cosplay Fabric
Different materials fit differently.
Stretch Fabrics
● Spandex
● Lycra
● Elastic blends
These provide more flexibility.
Structured Fabrics
● Polyester twill
● Cotton blends
● Uniform fabrics
● Faux leather
These have less stretch and require more accurate sizing.
What If You’re Between Sizes?
Many cosplayers naturally fall between two sizes.
When this happens:
● Compare all body measurements
● Prioritise bust/chest and hips
● Consider your height
● Think about the costume’s fabric
● Choose the larger size if unsure
Plus Size Cosplay
Cosplay is for everyone.
Many manufacturers now produce extended sizing across a wide range of anime and gaming costumes.
Availability varies by character and manufacturer, so always check the individual size chart provided on each product page.
Men’s and Women’s Cosplay Sizes
Although many anime costumes are listed as male or female versions, sizing is still based on body measurements rather than gender.
Always compare:
● Bust or chest
● Waist
● Hips
● Height
rather than assuming your usual clothing size.
Children’s Cosplay Sizes
Children grow quickly, making measurements even more important.
If your child is between sizes, choosing the slightly larger option often provides greater comfort and allows for future growth.
Cosplay Shoes
Cosplay footwear may also use different regional sizing systems.
Always check the conversion chart on the product page before ordering.
If you are between shoe sizes, selecting the larger size can improve comfort, especially when wearing thicker socks during conventions.
Can You Alter a Cosplay Costume?
Many costumes can be professionally altered for an even better fit.
Common alterations include:
● Shortening sleeves
● Taking in the waist
● Adjusting skirt length
● Hemming trousers
● Tightening straps
Minor tailoring can make a significant difference to your finished cosplay.
Measuring Before Every Purchase
Even experienced cosplayers should measure themselves before ordering.
Body measurements can naturally change over time, and every manufacturer follows slightly different patterns.
Taking just a few minutes to measure yourself can help avoid unnecessary returns and ensure your costume fits as intended.
