Trendyol Size Chart 2026: TR vs EU, UK and US Sizes by Brand

Trendyol has no single size chart. Every brand on it uses its own, so pick your size by brand and by your measurements. The same body lands on different rows at LC Waikiki, DeFacto and Koton. Measure your chest, waist and hips, then check the chart for that exact category: top, trousers or shoes.

How to measure yourself without pulling the tape tight

Measure on your body, shoulders relaxed, breathing normally. Keep the tape level around your chest, waist and hips. Tap the dots on the illustration to see where each measurement goes. Write the centimetres down before you go back to the product.

1. ChestAround the fullest part of your chest, under the arms.
2. WaistAt the narrowest point, without pulling in.
3. HipsAround the fullest part of your seat.
4. Inside legFrom the crotch to the ankle, along the inside of the leg.
5. FootFrom the heel to the longest toe, standing on paper.

Your 38 and Trendyol’s 38

Start from the brand you usually wear, but compare centimetres. On LC Waikiki’s women’s chart, the Turkish number is the same as the EU and French one. UK, US and Italian sizes are other names for the same row. Another brand may convert differently, so check its own row and its own cut.

Remember

The label is a number.
The measurements are yours.

The example at the top shows it at once: chest 90, waist 74 and hips 98 cm. LC Waikiki has a row that matches all three. On DeFacto’s and Koton’s standard charts, the waist puts you on a different row. Change the brand, not the tape.

Brand charts open only the one you need

Pick the brand and open your category. The charts come from the brands’ Turkish size guides and give body measurements, foot length or height. For a special line, plus sizes or jeans, use the chart the product page points to.

LC Waikiki uses one body chart for tops and bottoms, read from different columns. DeFacto and Koton publish separate charts. For men, watch the category most: the letter can be the same while the trouser number differs from the shirt number.

Shoes and kids’ clothes foot length and height

For shoes, start with your foot length. Measure both feet and use the longer one. In the matcher above, switch to “Shoes”, then “Women” or “Men”. It shows that group’s sizes, with UK and US where the brand prints them.

1. Stand on a sheet of paper.Stand straight, with your weight on both feet.
2. Mark both ends.Make a mark at your heel and at the tip of your longest toe.
3. Measure the distance.Take the longer foot and compare the centimetres on the brand you chose.

For children’s clothes, measure height without shoes. Pick “Kids” and the right group. The age is only the row’s name; height is what you compare. If the height falls between rows, open the product and check the sleeve and leg lengths. For babies, use the brand’s separate baby chart.

For a bra, note your underbust and your bust measurement. LC Waikiki lists band and cup on separate rows; open them in the brand’s size guide. Then check the sizing system and size of that model. The blouse chart does not apply to bras.

Turkish words in the product description

Read the fit before the item goes in your basket. Dar kalıp means a close, slim fit, normal kalıp a regular fit and bol kesim a loose one. Tap “Listen” to hear it, or “Show” to see the phrase full screen. The sample sentences below help you read a description.

When the page says the model wears an S, look at the model’s measurements and at the garment’s length too. If the seller suggests a size up, read it as advice for that item only. With stretch fabric, compare centimetres and decide whether you want it close-fitting or loose.

Between two sizes check the fit

When your chest points to one row and your waist to another, check the place that will limit movement. For a top, start with the chest; for trousers, with the waist and hips. Then compare the garment’s measurements with something comfortable you own, and choose how much room you want.

Keep this list open while you compare the product in another tab. The most useful reviews give measurements, the size ordered and how it fits. Stick to the same model, fabric and variant you are ordering.

Returns if the size is wrong

How long you have depends on where Trendyol delivers. Its English return policy gives 15 days from delivery to request a return. On its European sites it is 30 days in Bulgaria, Greece and Romania, and 14 days in Germany, Austria, Poland, Czechia, Slovakia and Hungary. Start in your account: “Order Details”, then “Easy Return”. Pick the items and the reason, and create the label for that delivery. Terms checked in October 2026.

• Label from Trendyol. Every return starts in your account.
• Separate deliveries. Make one label for each, and pack the right items together.
• Sealed underwear and swimwear. Under the hygiene rules, Trendyol takes them back only in unopened packaging.
• Courier receipt. Keep it until the refund is done.

A return is not always free. In Germany, Austria, Poland, Czechia, Slovakia and Hungary, Trendyol deducts a fee per item from the refund: in Germany €2.99 an item, at most €8.99 per return. If what you keep falls below the free-delivery threshold, the original delivery fee comes off the refund too. After the courier collects the parcel, Trendyol can take up to 14 business days to receive and process it; your bank sets the rest.
