Trendyol Size Chart 2026: The Ultimate Guide (TR vs. EU/US Fits)
Table of Contents
Let’s be honest: There is nothing more frustrating than tearing open a package you have been waiting for, only to find that your new favorite piece cuts off your circulation or hangs like a potato sack. With international marketplaces like Trendyol, this risk is significantly higher. Why? Because a “Size 38” in Istanbul is not always the same as a “Size 38” in London, Berlin, or New York.
Many international customers fall into the trap of ordering their usual local sizeand end up disappointed. The hard truth is: Turkish fashion often favors a slimmer, more fitted cut. If you want to shop smart and avoid the hassle of returns, you need to ignore the tag and trust the tape measure.
In this guide, we decode the Trendyol size charts for 2026. We move beyond the basic numbers to explain how Turkish sizes (TR) actually translate to Western standards (EU/US/UK) and which common pitfalls you need to dodge.
The Reality Check: TR vs. Western Sizes
Technically, Turkish manufacturers align with European standards (EU). That sounds straightforward, but there is a catch: Western sizes (especially German, UK, and US brands) have heavily adopted “vanity sizing” over the years, becoming more generous to flatter the customer. Turkey hasn’t fully followed this trend yet.
- The Practitioner Rule: A Turkish (TR) 38 corresponds to a standard European (EU) 38. However, for customers used to brands like H&M or Old Navy, this will often feel like a “small 38” or even a 36.
- Our Advice: If you are between sizes or prefer a relaxed fit, always order one size up when buying from Turkish brands. This is especially true if you are used to the looser cuts found in the US or Northern Europe.
Insider Tip: For trousers and jeans, ignore the generic size labels entirely. Look for the centimeter measurements (waist/hips), as the “Kalip” (fit/mold) varies wildly between brands.
Street Smarts: How to Avoid Returns at Trendyol
Size charts are useful, but real world experience is better. Returns can be a headache involving customs forms and shipping fees. If you are ordering from abroad, check out our guide to Trendyol delivery times and return fees to understand the stakes.
Here are three practitioner tips to get it right the first time:
- Know Your Fabric: Items with a high Elastane content are forgiving and can stretch to fit. However, for “Rigid Denim” (100% cotton) without stretch, there is zero margin for error. When in doubt with rigid fabrics, always size up.
- Watch the “Milla” Label: Trendyol’s private label, “Trendyol Milla,” is incredibly popular but is designed with a very youthful, body con aesthetic. If you are expecting a relaxed fit, you won’t find it here. Measure twice.
- Decode the Reviews: Don’t just look at the star rating. Filter for reviews from your region (if possible) or translate the Turkish comments. Look for the phrase “bir beden büyük alın” (buy one size larger). If you see that repeated, believe it.
Curious about how Trendyol stacks up against other Turkish giants? It is worth comparing their sizing consistency with LC Waikiki, Turkey’s retail giant, which tends to offer a more generous, standard fit closer to Western expectations.

Is a Trendyol Size 38 really a Western Size 38?
Yes and no. Officially, it maps to an EU 38. However, in practice, it often feels like a 36/38 hybrid. If you don’t like your clothes skin tight, size 40 is often the safer, more comfortable choice for someone who typically wears a standard 38. If you are looking for shoes to complete the outfit, the sizing is generally more standardcheck our guide on buying Ecco shoes in Turkey for footwear pricing and tax-free tips.
