Trendyol Size Chart 2026: The Ultimate Guide (TR vs. EU/US Fits)

Trendyol has no single size chart: each seller sets its own. What stays fixed is the scale. On the charts of LC Waikiki and Sisley, Turkish brands whose clothes are also listed on Trendyol, a Turkish (TR) size 38 is a French 38, an Italian 42, a UK 10, a US 6 and a German 36; a German 38 is a TR 40.

The centimetres differ too: a 90 cm bust, 70 cm waist and 98 cm hips is a TR 38 at LC Waikiki and İpekyol but a TR 40 at Sisley, so check the chart on the product page. Charts read on 29 September 2026.

The Reality Check: TR vs. Western Sizes

Turkish women’s sizes use the same numbers as the French scale: LC Waikiki’s chart lists TR 38 and FR 38 side by side. Against the other systems you shift by a fixed number: on LC Waikiki’s chart, UK is TR − 28, US is TR − 32 and Italy is TR + 4; on Sisley’s, Germany is TR − 2.

The German 38 trap: if you wear a 38 in Germany, Sisley’s chart matches you to a TR 40. Order a TR 38 and you get its German 36.

Measure Yourself, Then Match the Chart

The tool below compares yours with the charts of LC Waikiki, İpekyol and Sisley side by side, and it covers men, kids and shoes too.

How to measure

Use a soft tape measure, flat and parallel to the floor, as in LC Waikiki’s own guide.

1. Bust or chest: widest point of your chest.
2. Waist: hands on your waist; measure around the spot under them.
3. Hips: widest part of your hips.
4. Inside leg (trousers): crotch to ankle bone.
5. Neck (shirts): where a collar sits.
6. Height (kids): barefoot, floor to top of head.

When your numbers point to different rows, the tool takes the largest size any of them calls for: our rule of thumb, not the brands’. Charts can list the body or the garment: LC Waikiki lists body measurements (“Beden Ölçüleri”), while Koton says its tables show averages and that deviations of 2 cm are normal.

Find the product’s own chart. On a Trendyol listing, look near the size selector for “Beden Tablosu” (size chart). We could not open Trendyol’s product pages to confirm where it sits; if it is missing, ask the seller for the garment’s measurements.

Women’s Size Charts in cm: LC Waikiki, İpekyol and Sisley

The same Turkish size means a different body at each brand, most of all at the waist: a TR 38 has 74 cm at LC Waikiki, 70 cm at İpekyol and 66 to 70 cm at Sisley. Cells read bust/waist/hips in cm.

No brand is roomier everywhere: LC Waikiki’s waist is the largest from TR 34 to 44, but İpekyol’s bust and hips are larger at TR 34 and 36. Sisley ships Turkish sizes with the Italian label sewn in, so a TR 38 arrives tagged 42.

For trousers and jeans, read the waist and hip centimetres, not the label: the cut (kalıp) varies a lot between brands. Sisley’s jeans chart adds the inside leg (sizes 25 to 36), and LC Waikiki’s trousers come in regular and long (U/L) lengths about 5 cm apart. More on the brand: our LC Waikiki guide.

LC Waikiki’s bra bands follow the underbust measurement, from 70 (68 to 72 cm) to 100 (98 to 102 cm), with the cup table on its size page. Underwear can fall under the hygiene rules below.

Men’s Size Chart: TR vs. EU, US and Italy

Men’s Turkish sizes are even numbers from 46 to 62, and the number is the European size. On LC Waikiki’s chart a TR 50 is an EU 50, a US 38 and an Italian 48 (US is TR − 12, Italy is TR − 2).

LC Waikiki’s men’s chart has no UK or German column and we found no sourced conversion, so we give none. For shirts, check the neck too (39 to 40 cm for a TR 50); for trousers use the waist and, if listed, the inside leg.

Kids’ and Baby Sizes

Go by height, not by age: LC Waikiki’s chart pairs each age band with a height. Between two rows, we suggest the larger.

Baby sizes are set by height too: newborn is 50 cm, then 56, 62, 68, 74, 80, 86, 92 and 98 cm for 0–1, 1–3, 3–6, 6–9, 9–12, 12–18, 18–24 and 24–36 months; premature sizes are 37 and 44 cm. Weight ranges are in the tool.

Shoe Sizes: TR vs. UK and US

Turkish shoe numbers are European sizes: a TR 38 is an EU 38 and, on LC Waikiki’s chart, suits a foot about 24 cm long. Match your foot length in centimetres; it beats converting numbers.

We use Sisley’s UK and US figures because LC Waikiki’s women’s columns disagree with them by up to a full size (US 4.5 for both TR 35 and 36, where Sisley gives 5 and 5.5 to 6); Nike Türkiye agrees with Sisley to within half a size.

LC Waikiki’s kids’ shoes run from TR 26 (foot 16.3 cm) to TR 39 (24.8 cm) and baby shoes from TR 16 (9.4 cm) to TR 25 (15.7 cm); the tool has every size. We list no UK or US sizes for children, because the column we read has an obvious misprint.

To measure your foot, follow Nike Türkiye’s method: stand on a sheet of paper, mark the tip of your big toe and the back of your heel, and measure between the marks. Use the longer foot, and take the larger size if you land between two. Buying Ecco? See our guide to buying Ecco shoes in Turkey.

Street Smarts: How to Avoid Returns at Trendyol, and How They Work

Read the seller’s own chart first, then the fabric, then the fit comments in the reviews; the label comes last.

• Know your fabric. Elastane forgives a size that is a little small; rigid, non-stretch denim does not, so with rigid fabrics we would size up when in doubt.
• Check each “Milla” style on its own. Trendyol’s careers page says its private label, Milla, creates up to 15,000 new styles each season, so we found no fit description for the label as a whole.
• Decode the reviews. One fit comment is an opinion; the same comment repeated is a signal, not proof. Phrases to look for:

Returns and Exchanges If the Size Is Wrong

Trendyol’s English return policy lets you request a return within 15 days of receiving an order, free of charge; the refund takes up to 14 business days after the courier collects the parcel. The policy for Germany, Austria, Poland, Czechia, Slovakia and Hungary allows 14 days and deducts a per-item fee (below); Germany’s refund page adds that money is released within 14 calendar days of receipt and then usually takes 2 to 10 business days to arrive. Neither policy describes a size swap: the documented route is to return the item and order the other size. For delivery and fees to Germany, see our guide to Trendyol delivery times and return fees.

Ordering two sizes? Where a per-item fee applies, sending one back costs it. The English policy does not say which countries it covers, so check the policy for your own.

Inside Turkey, the Ministry of Trade’s consumer guide (dated 17 August 2026) allows withdrawal within 14 days of receipt without giving a reason. The seller must refund everything, delivery costs included, within 14 days of you handing the parcel to the carrier, and return shipping is free to you if you use the carrier named in the seller’s information, or any carrier when none is named.

Underwear and other exceptions. Trendyol’s English policy makes hygiene-category products “intended to come into direct contact with the human body” non-returnable, even if unused; the Ministry’s guide excludes underwear and earrings once their protective packaging is open. The policy does not name underwear or swimwear, so check the listing’s return note and keep any hygiene seal intact.

Frequently Asked Questions (FAQ)

How do Trendyol jeans fit?

It depends on the brand and the seller, and we found no independent data on how Trendyol jeans fit as a group. Read the waist, hip and inside-leg columns, check the fabric for elastane and look for fit comments in the reviews. For the wider picture, read our 2026 Trendyol Survival Guide.

Is a Trendyol size 38 really a Western size 38?

On the French scale, yes: TR 38 is FR 38. Against a German size it is not: Sisley’s chart pairs TR 38 with a German 36 and a German 38 with TR 40. LC Waikiki’s chart gives TR 38 as UK 10 and US 6. The brands’ centimetres differ as well, as the women’s table above shows.

Should I order one size up?

Only if your measurements point that way. Between two sizes we suggest the larger, though stretch fabric is likely to work in either. Do not size up by default: LC Waikiki’s TR 38 already has a 74 cm waist, wider than İpekyol’s 70 cm.

Can I exchange an item for another size on Trendyol?

Neither return policy we read describes a size exchange. The documented route is to request a return within the window and order the size you need. Check the return fee for your country first.

Do letters (S, M, L) match the numbers?

Not between brands. An M is a TR 38 at LC Waikiki and İpekyol but a TR 40 at Sisley. Compare centimetres, not letters.

Sources and How We Checked This Guide

On 29.09.2026 we read the size guides of LC Waikiki, İpekyol, Sisley and Koton, Nike Türkiye’s shoe guide, three Trendyol return policies, the Ministry of Trade’s consumer guide and Trendyol’s careers page, copied the tables from those pages and checked the conversion rules against every row. We could not check Trendyol’s own size-guide pages, so the tables use the brands’ charts instead.
