Western shoppers in Thailand often need to compare local clothing and shoe sizes with US, UK, or EU labels, but no single conversion works across every brand. Clothing sizes vary by label, and shoe charts use different scales, so your best guide is the retailer’s chart and your own measurements.
The charts and examples below show how to compare sizes, while practical measuring and fit tips can help you choose with more confidence. Start with the apparel and footwear charts, then use the brand’s specific guidance before ordering.
Key Takeaways
- Thailand has no universal clothing-size conversion, so US, UK, and EU labels can’t be matched reliably by letter size alone.
- Compare your bust, waist, hip, or chest measurements with the retailer’s chart, and check whether it lists body or garment measurements.
- Shoe conversions vary by brand and category; use the right men’s, women’s, or unisex chart, such as Onitsuka Tiger Thailand’s shoe size guide.
- Measure both feet in centimeters because their lengths may differ; Skechers Thailand’s measuring instructions offer a practical method.
- Before ordering, match your measurements to the specific product chart rather than assuming one brand’s conversion will fit another.
Thai Clothing and Shoe Sizes: US, UK and EU Conversion Chart
There is no single official Thai clothing or shoe conversion chart that applies to every brand. Use the examples below as brand-specific references, then check the chart on the product page before choosing a size.
Compare clothing sizes by body measurements, not just labels
Thai clothing commonly uses letter sizes such as S, M, and L, as well as numeric labels. However, an M in one brand or style may fit differently from an M elsewhere. Compare your measurements in centimeters with the brand’s own chart instead of relying on a direct Thai-to-US, UK, or EU label match.
Check the chart’s measurement basis, too. Body measurements describe the person wearing the clothing. Flat garment measurements describe the item laid flat, so they may be much smaller than measurements taken around the body. For a garment that should fit comfortably, compare the stated garment dimensions with a similar item you own. Height references can help narrow the options, but treat them as guidance rather than a guarantee of fit.
Use shoe conversion examples with the brand clearly named
Shoe conversions also vary by brand and sizing category. These examples show why a single conversion table can mislead:
| Brand and category | US | EU | Foot length |
|---|---|---|---|
| Onitsuka Tiger Thailand, men’s/unisex | 8 | 41.5 | 26 cm |
| Onitsuka Tiger Thailand, women’s | 8 | 39.5 | 25 cm |
| Bata Thailand, chart example | Not listed | 39 | 25.1 cm |
The Onitsuka Tiger examples come from separate men’s/unisex and women’s charts. Its official shoe size guide shows why you should check the category as well as the US number. The Bata Thailand chart lists EU, UK, and centimeter values; for example, EU 39 corresponds to UK 5 and 25.1 cm. It does not provide a US equivalent in the chart data shown here.
PUMA and ASICS also publish their own category-specific charts, with separate guidance for groups such as men’s, women’s, and children’s shoes. Use the chart that matches the product and category. Don’t infer missing values or fill gaps using another brand’s chart, since its conversion may not match.
How to read Thai apparel size charts and choose a better fit
Thai apparel labels don’t convert neatly to US, UK, or EU sizes. For a better fit, use the product’s own size guide, measure the relevant parts of your body, then compare those numbers with the chart instead of choosing by label alone.
Check fit notes, cut, and fabric before choosing a size
Start with the size guide on the specific product page. Check whether the chart lists body measurements or garment measurements, since garment dimensions describe the clothing itself and may include room for ease. Then measure the areas relevant to the item, such as your chest or bust, waist, and hips, and compare those measurements with the chart.
Next, read the product’s fit notes. A slim-cut shirt may feel close through the chest, while a relaxed cut allows more room. An oversized style is designed to hang looser, so sizing up may create more volume than you want. Fabric matters, too: stretch material can move with your body, while a non-stretch woven fabric usually offers less give.
For example, two people who wear a US medium may need different Thai brand sizes. One might match the brand’s medium chest and waist range, while the other measures closer to its large range. The chart helps narrow the choice, but it can’t account for every cut, fabric, or personal preference. If you’re between sizes, use the product notes and consider whether you prefer a closer or looser fit.
Use height and children’s measurements as supporting clues
Some brand charts include a height reference or use numeric children’s sizes. Treat height as one clue, not a complete fit recommendation. Compare the listed height range with the child’s chest and waist measurements as well, since children of the same height can have different proportions.
Onitsuka Tiger Thailand, for example, lists children’s clothing sizes 110, 120, 130, and 140, with height ranges of 105-115 cm, 115-125 cm, 125-135 cm, and 135-145 cm. The chart also gives chest and waist ranges, so check those alongside height in the Onitsuka Tiger Thailand clothing size guide. These labels are specific to the brand, not a standard used across Thailand.
Measure your feet at home before converting shoe sizes
Before comparing Thai, US, UK, or EU shoe labels, measure both feet in centimeters. This gives you a useful starting point, but the brand’s chart and the shoe’s intended fit still matter.
Record the longest foot measurement accurately
Place a sheet of paper on a hard floor with one edge against a wall. Wear the socks you expect to use with the shoes, then stand upright with your heel lightly touching the wall. Mark the tip of your longest toe, step off the paper, and measure from the wall edge to the mark in centimeters.
Repeat the process with your other foot. Feet can differ in length, so use the longer measurement as the cautious reference when checking a size chart. For a more consistent reading, keep your weight balanced and avoid bending your toes while standing.
Brands may describe the measurement process differently. Skechers Thailand’s published method has you trace each foot and add a 0.5 cm offset to the longest outline before measuring. Onitsuka Tiger Thailand’s shoe guide describes measuring from the heel against the wall to the tip of the longest toe. Follow the method shown by the brand whose shoes you’re considering, rather than combining the two approaches.
Match centimeters to the right shoe chart
Treat your centimeter measurement as a reference, not a promise that every shoe with the same listed length will fit alike. Brands can use different sizing systems, and shoe shape, width, and intended fit affect how a size feels. A snug-fitting style may need a different choice than a roomy sneaker, even when both charts show the same foot length.
First, choose the chart for the correct category: men’s, women’s, unisex, or children’s. Then check what the brand’s centimeter column represents. It may refer to foot length or another sizing reference, so don’t assume the meaning without reading the chart notes.
Finally, review the product’s fit guidance, especially notes about width or a close fit. Compare your longer foot measurement with the brand’s chart, then use the category and product details to select a size. If the chart recommends a different method or fit allowance, follow its instructions rather than applying a generic conversion.
Avoid common sizing mistakes when shopping from Thailand
Size conversion charts are useful for narrowing down your options, but they can’t guarantee a good fit. Before ordering or buying in person, check the exact brand, product category, and fit details, since the same size label can mean different things across charts.
Don’t assume US, UK, and EU sizes convert the same way everywhere
Brands use different sizing scales, and some include half sizes or unusual steps between EU sizes. Clothing charts also vary by brand and category, so a letter size such as M is only a starting point. Check the chart attached to the item you’re considering rather than carrying a conversion over from another label.
Onitsuka Tiger shows why the category matters. In its Thailand shoe guide, a men’s/unisex US 8 corresponds to EU 41.5 and 26 cm, while a women’s US 8 corresponds to EU 39.5 and 25 cm. That’s a full centimeter difference in the chart’s listed measurement, despite the shared US size. Before choosing, confirm whether the product uses a women’s, men’s/unisex, or children’s chart. The Onitsuka Tiger Thailand shoe size guide lists the categories separately.
When shopping in a store, check the size label and try on both shoes, since left and right feet may not feel identical. Online, keep the chart open beside the product page and confirm that the listed size applies to that specific style.
Check returns, reviews, and product measurements before checkout
A size chart won’t tell you everything about how a garment or shoe feels. Read recent customer reviews for comments about tightness, roominess, or whether the item runs small or large. Give more weight to reviews that mention the same product, since fit can change between styles from one brand.
Also check whether the seller accepts returns or exchanges, and note any deadlines, shipping costs, or exclusions. This matters most for final-sale products, which may not qualify for a size exchange. If the listing includes garment measurements, compare them with a similar item you already own. For shoes, look for the product’s fit notes and any listed length or width information.
If a chart is unclear or a measurement is missing, message the seller before paying and ask them to confirm the relevant dimensions. Save the reply and order details until the item arrives. These quick checks can help you avoid choosing by label alone, especially when a return would be difficult.
Frequently Asked Questions
Are Thai clothing sizes smaller than US sizes?
There’s no standard Thai-to-US clothing conversion, so it’s not reliable to assume Thai sizes always run smaller. Compare your measurements with the specific brand’s chart, and check whether it lists body or garment dimensions.
Does Thailand use centimeters for shoe sizes?
Many brand charts sold in Thailand include measurements in centimeters, but check what the number describes. It may refer to foot length or follow a brand’s own sizing method, so read the chart notes before choosing.
Is a 25 cm shoe size the same across brands?
No. A 25 cm reference on one brand’s chart doesn’t guarantee the same fit in another brand, since sizing charts and shoe shapes vary. Use the product’s own chart and fit guidance.
Can I use my EU shoe size when shopping in Thailand?
You can use it as a starting point, but confirm the equivalent on the Thai retailer’s chart. Some charts list EU sizes alongside UK sizes and centimeters, while others use different columns or categories.
What does Mondopoint mean, and is it the standard in Thailand?
Mondopoint is an international footwear size designation based on foot measurements. The ANSI overview of ISO 9407 explains the system, but that doesn’t make it a universal Thai retail standard. Check the brand’s chart for the sizing method it uses.
Are clothing size numbers in Thailand the same as EU sizes?
Not necessarily. A number on a Thai clothing label may follow that brand’s own system rather than match an EU size. Check the garment’s measurement chart before comparing labels.
