Litbuy Sizing Masterclass: Converting Asian Sizes for US Shoppers
Size-related returns are the single biggest source of buyer dissatisfaction in spreadsheet shopping. The problem is not that products are poorly made. It is that sizing standards differ dramatically between Chinese manufacturing and US consumer expectations. A US Medium t-shirt often maps to an Asian XL. A US size 10 sneaker might need a 44 or 44.5 in EU sizing, depending on the factory batch. This guide gives you the exact conversion methodology that eliminates guessing.
The Golden Rule: Measure in Centimeters
Never order by label size. Always order by physical measurement in centimeters. This is non-negotiable. Grab a flexible measuring tape and measure a garment or shoe that fits you well. For shirts, measure chest width, shoulder width, sleeve length, and total length. For pants, measure waist, inseam, thigh width, and leg opening. For shoes, measure insole length and width. Compare these numbers directly against the size chart in the Litbuy listing.
| US Shoe Size | EU Equivalent | Insole CM | Asian Label |
|---|---|---|---|
| 7 | 40 | 25.0 | 40 |
| 8 | 41 | 26.0 | 41 |
| 9 | 42.5 | 27.0 | 42-43 |
| 10 | 44 | 28.0 | 44 |
| 11 | 45 | 29.0 | 45 |
| 12 | 46 | 30.0 | 46 |
Apparel: The Two-Size Rule
For most apparel categories, add one to two sizes when converting from US to Asian sizing. A US Medium t-shirt typically corresponds to an Asian Large or Extra-Large. Hoodies and jackets, which are often designed with slimmer cuts, may require going up two full sizes. The critical measurement for tops is chest width. For bottoms, it is waist measurement in centimeters. Do not rely on length measurements alone, as Asian garments are often cut shorter in the torso and sleeves even when the width is correct.
Sneakers: Batch-Specific Variation
Sneaker sizing is more complex because different factories use different lasts. Some batches run true to size. Others run half a size small or large. The only reliable method is to check community sizing notes for the specific batch you are buying. Search the batch code plus sizing in Reddit or Discord. If no community data exists, order based on insole CM and add a 0.5cm buffer for thick socks.
Accessories and One-Size Items
Headwear, belts, bags, and jewelry often list dimensions rather than sizes. For hats, measure your head circumference in centimeters and compare against the cap's adjustable range. For belts, measure your waist where the belt sits and add 10-15cm for overlap. For bags, verify dimensions against items you already own rather than imagining scale from photos. Bags are the most commonly misjudged accessory category because product photos use clever angles to exaggerate perceived size.
Create a personal measurement profile in your phone's notes app. Include your chest, waist, inseam, shoulder width, head circumference, and typical insole length. Paste these numbers directly into size chart comparisons every time you shop.
Frequently Asked Questions
What if the size chart seems wrong?
Ask your agent to request actual measurements from the seller before purchasing. This service usually costs nothing or a small fee and prevents costly returns.
Should I size up or down if between sizes?
For apparel, size up. You can tailor down but cannot expand. For sneakers, check the batch-specific community notes. When in doubt, add 0.5cm to your insole measurement.
Do Asian sizes vary between sellers?
Yes. Size charts are seller-specific, not standardized. Always use the chart in the specific listing you are buying from, even if you have purchased from the same seller before.
