How to Choose the Right Clothing Size When Shopping Online: Full Guide with Charts

Ordering clothes online from Turkey, the USA, the UK, Germany or Spain is now part of everyday life. But the main challenge remains the same: how to choose the correct size so the item fits perfectly?

Product pages usually show S, M, L, XL, XXL or numeric sizes like 34, 36, 38, 40. Many users search for “What is size S?”, “What is size L?”, “What is XL?”, simply because every country uses its own size system, and customers do not always know their exact body measurements.

Below is a clear and practical guide that explains men’s and women’s sizing, international size conversions and key differences between countries from which people most often order using Aser Cargo Express.

How to take your measurements correctly

Before choosing a size, you need to measure your body accurately:

Bust/Chest — measure around the fullest part, tape parallel to the floor.
Waist — the narrowest part of the torso.
Hips — the widest part of the hips.
Height — important for trousers and outerwear.

If your measurements fall between two sizes, choose:

the smaller one for fitted items,
the larger one for loose-fit or oversize styles.

Size differences by country

Turkey

Turkish brands (LC Waikiki, Koton, Trendyol labels) use a system almost identical to the global INT standard (S, M, L, XL).

Numeric women’s sizes convert as follows:

TR	INT
34	XS
36	S
38	M
40	L
42	XL
44	XXL

This makes ordering from Turkey one of the easiest options — sizes are very close to European and Azerbaijani standards.

Practical tips for choosing the right size

Save your measurements in your phone; this avoids re-measuring every time.
Always check the brand’s own size chart.
Read customer reviews — they often mention “true to size” or “runs small/large”.
For jeans and trousers, focus on waist and length rather than the letter size.
If unsure, choose relaxed-fit models.
