Should I size up or down for Asian clothing?

Size up one full size from your US size for Asian clothing. For an oversized fit, go up two sizes.

What if I am between sizes?

Always size up when between sizes. It is much easier to have an item tailored down than to stretch out something too small.

Do rep sneakers fit the same as retail?

High-tier batches usually match retail sizing closely. Budget batches may run slightly smaller. Use cm measurements for accuracy.

How do I measure my own clothes for comparison?

Lay the garment flat on a hard surface. Measure across the chest at the widest point, shoulder seam to seam, sleeve from shoulder to cuff, and total length from collar to hem.

The Ultimate Sizing Guide: Asian to US/EU Conversion for Every Category

Never order the wrong size again. Complete conversion tables, measurement techniques, and category-specific tips for shoes, hoodies, pants, and more.

Sizing is the #1 reason for returns and exchanges in the rep community. Asian sizing charts are fundamentally different from US and EU standards, and every category — shoes, hoodies, pants, jackets — has its own quirks. This guide eliminates the guesswork with precise conversion tables and measurement techniques you can do at home in under five minutes.

Why Asian Sizing Is Different

Asian sizing generally runs one full size smaller than US sizing for clothing, and half to one full size smaller for shoes. This is not a flaw — it is simply how the sizing system is calibrated for the average East Asian body type. Understanding this upfront prevents 80% of sizing issues before you even place an order.

Shoe Sizing: The Most Critical Conversion

Shoes are unforgiving when it comes to size errors. A half-size too small and your toes suffer; too large and the shoe creases badly. The golden rule: measure your insole length in centimeters and match it directly to the seller's cm sizing. Do not convert US to EU to Asian — go straight to the cm measurement.

US Men	US Women	EU	UK	CM (Insole)
7	8.5	40	6	25.0
8	9.5	41	7	26.0
9	10.5	42.5	8	27.0
10	11.5	44	9	28.0
11	12.5	45	10	29.0
12	13.5	46	11	30.0

How to Measure Your Feet Correctly

Place a blank sheet of paper on a hard floor against a wall.
Stand with your heel firmly against the wall and your full weight on the foot.
Mark the longest point of your toe on the paper.
Measure from the wall edge to the mark in centimeters.
Add 0.5-1.0 cm for comfort depending on the shoe type.
Compare this total to the seller's cm size chart.

Measure both feet and use the larger measurement. Most people have one foot slightly bigger than the other, and ordering for the smaller foot is a common mistake.

Clothing Sizing: Hoodies, Tees, and Jackets

For tops, the most reliable approach is to measure a favorite garment from your current wardrobe and compare it to the seller's flat measurements. Key dimensions are chest width (armpit to armpit), shoulder width (seam to seam), sleeve length, and total length.

US Size	Asian Size	Chest (cm)	Length (cm)
S	M	104-108	66-68
M	L	108-112	68-70
L	XL	112-116	70-72
XL	2XL	116-120	72-74
2XL	3XL	120-124	74-76

Pants and Shorts: Waist and Inseam

Pants are more forgiving than shoes but still require attention. Measure your waist at the level where you actually wear your pants, not at your natural waistline. For inseam, measure from the crotch seam to the ankle hem on a pair of pants that fits you perfectly. Asian pants often have shorter inseams, so tall buyers should verify this dimension carefully.

Category-Specific Sizing Notes

Sizing Quirks by Category

Sneakers

Always use cm insole measurement. Asian shoe sizes run 0.5-1 size smaller than US. Order half size up minimum.

Hoodies

Asian hoodies fit one size smaller. For oversized streetwear fit, go two sizes up from your normal US size.

T-Shirts

Tees are the most consistent. One size up from US is usually perfect. Check shoulder width if you have broad shoulders.

Jackets

Jackets vary wildly by style. Puffers run small; shells and technical jackets may run true to size. Always check the size chart.

What to Do When There Is No Size Chart

If a seller does not provide detailed measurements, message them before ordering or skip the listing. Never guess your size based on the S/M/L label alone. In our community, we maintain a spreadsheet of seller-specific sizing tendencies so you can cross-reference before buying.

Summary

Accurate sizing starts with precise self-measurement and ends with careful comparison to seller charts. The 10 minutes you spend measuring and converting will save you weeks of exchange delays and potential disappointment. Keep a note on your phone with your key measurements for instant reference whenever you shop.
