Quick answer: National Geographic Korea adult outerwear and tops commonly use Korean numbers from 80 to 115. In the brand’s official global chart, 90 corresponds to Korea S, 95 to M, 100 to L, 105 to XL and 110 to XXL. However, the international equivalent is usually one letter smaller, and the exact garment measurements and fit description should always take priority.

National Geographic Korea Size Conversion Chart
The official National Geographic regional size guide lists the following adult outer/top sequence. The US/Australia column is one letter smaller than the Korean letter label, which is why an international shopper should not treat a Korean “L” as automatically equal to a familiar Western L.
| Korean number | Korea label | US/Australia equivalent |
|---|---|---|
| 80 | XXS | XXXS |
| 85 | XS | XXS |
| 90 | S | XS |
| 95 | M | S |
| 100 | L | M |
| 105 | XL | L |
| 110 | XXL | XL |
| 115 | XXXL | XXL |
This chart is a starting point, not a guarantee of fit. A semi-overfit sweatshirt, regular-fit jacket and slim women’s top can all feel different even when the tag shows the same number.
Real Korean Tag Example: Size 110
The original working photos below show a Korean-market National Geographic black T-shirt with style code N265UTS020. The paper tag identifies the color as BLACK (099), the selected size as XXL (110), and the full available size range as 90, 95, 100, 105, 110 and 115. The listed Korean retail price is ₩49,000.
This real tag supports the official category conversion: 110 is labeled Korea XXL, while the international reference chart corresponds to US/Australia XL. It also shows why shoppers should record both the letter and number instead of relying on only one size label.
What Do Korean Sizes 90, 95, 100 and 105 Mean?
Size 90
Size 90 is Korea S in the official chart and is closest to US/Australia XS at the category level. It may suit a smaller adult frame, but an oversized unisex design can still feel roomy.
Size 95
Size 95 is Korea M and corresponds to US/Australia S in the official conversion. This is a common point of confusion for international shoppers who see the letter M and expect a Western medium.
Size 100
Size 100 is Korea L and corresponds to US/Australia M. For many unisex sweatshirts and jackets, it is a useful reference size for shoppers who normally wear an international medium, but the garment’s chest width and length must still be checked.
Size 105
Size 105 is Korea XL and corresponds to US/Australia L. Do not size down automatically if the item is meant for layering or has a regular outdoor fit.
Sizes 110 and 115
Size 110 is Korea XXL and the category-level equivalent of US/Australia XL. Size 115 is Korea XXXL and the equivalent of US/Australia XXL. Availability varies by collection and product.
How Does National Geographic Korea Clothing Fit?
There is no single fit for the entire brand. National Geographic Korea sells unisex, men’s, women’s and kids’ products, and product descriptions may identify a style as regular fit, semi-overfit or another silhouette. The category chart explains the numbering system, while the product measurements explain the actual garment.
- Unisex sweatshirts and hoodies: can be roomier through the body and shoulders.
- Outerwear: may include space for layering, but insulated jackets can feel different from lightweight shells.
- Women’s lines: may use a different cut even when the number looks familiar.
- Kids’ products: require the kids-specific chart and should not be converted from adult numbers.
- Older seasons: may not match the measurements of a similarly named current item.
If you are researching a Korean-market item, also copy its complete style ID from the tag. Our National Geographic Korea product codes guide explains how to identify the style, color and size information on a Korean tag.
National Geographic Korea Bottom Sizes
The official category chart uses separate numerical sequences for women’s bottoms and men’s/unisex bottoms.
| Korea label | Women’s bottom | Men’s/unisex bottom |
|---|---|---|
| XXS | 64 | 64 |
| XS | 67 | 67 |
| S | 70 | 71 |
| M | 73 | 76 |
| L | 76 | 81 |
| XL | 81 | 86 |
| XXL | — | 91 |
| XXXL | — | 96 |
These numbers are size categories, not a substitute for checking waist, hip, rise and inseam measurements. Compare a pair of trousers you already own with the exact product measurements.
National Geographic Korea Shoe Sizes
Korean footwear is usually labeled in millimeters. The official adult chart runs from 225 mm to 280 mm in 5 mm steps. Its reference conversions begin at US women’s 5.5 / US men’s 4.5 for 225 mm and reach US women’s 11 / US men’s 10 for 280 mm.
Millimeter sizing is clearer than letter sizing, but shoe shape still matters. Measure both feet while standing, use the larger measurement and consider sock thickness. If the official product page provides an internal length or width note, follow that style-specific information.
How to Choose the Right Size
- Find the exact style code. Similar-looking products can have different measurements.
- Read the fit description. Look for unisex, regular fit, semi-overfit, women’s or kids.
- Use garment measurements. Chest width, total length, shoulder width and sleeve length are more reliable than letters alone.
- Compare with your own clothing. Measure a well-fitting garment laid flat using the same points.
- Allow for layering. Jackets and winter products may need additional room.
- Check the return policy. International returns can cost more than the item’s original domestic delivery.

Frequently Asked Questions

Is size 95 a small or medium?
It is labeled Korea M and corresponds to US/Australia S in the official chart.
Should I size up in National Geographic Korea?
Not automatically. First convert the category size, then check whether the exact item is regular, oversized or fitted. Use its measurements and your preferred wearing style.
Are Korean and overseas sizes identical?
No. The official chart itself shows that Korean letter labels and US/Australia letter equivalents differ. Regional product ranges and fit descriptions can also vary.
