Frequently asked questions
Are clothing size conversions exact?
No. There is no enforced international standard: vanity sizing, brand differences, and cut mean a US 8 can vary by a full size between labels. These are commonly-used cross-reference tables — always check a brand’s own size chart and measure yourself when it matters.
How does weight change relate to clothing size?
There is no fixed rule — it depends on where you carry weight and the brand. As a rough observation people often drop roughly one dress size for every 1–2 inches (2.5–5 cm) lost at the waist, which is why LoseSize focuses on tracking measurements, not just scale weight.
