How to Read a Clothing Size Chart

Start with the exact product

A brand can sell slim, regular and oversized pieces under the same letter label. Open the chart on the product you are buying, not a screenshot for another collection. UNIQLO directs shoppers to product measurements because finished dimensions vary by design.

Check units before comparing

Inches and centimeters are different units for the same dimension: one inch is exactly 2.54 cm. Keep unrounded measurements while converting and only round when presenting the result. Confusing a flat width in centimeters with a body circumference in inches creates more than a small sizing error.

Read all the relevant dimensions

For tops, chest or bust matters, but shoulder, sleeve and length can be decisive. For bottoms, waist alone cannot capture hip room, rise and inseam. When measurements point to different sizes, prioritize the dimension the brand identifies and the most constrained part of the garment.

Do not assume the letter transfers across markets

An M in one country or collection need not equal an M elsewhere. Even a revised body chart may not indicate that the garment itself changed. Compare actual measurements and the product description rather than applying a universal country offset.

Before you order

1. Confirm country or regional store.
2. Read body-versus-product definitions and units.
3. Measure using the illustrated locations.
4. Compare required dimensions and intended fit.
