whatsizetobuy is an independent English-language fit guide site. We answer “does it run big or small?” at the model and cut/line level — not just brand averages or generic US↔EU charts.
Generic converters are everywhere. What shoppers still struggle to find is whether this last or cut runs long, short, narrow, or true to size. That is our focus: original, structured fit pages plus converters and brand comparisons.
We label uncertainty on purpose. Most fit rows stay low confidence / draft until checked against multiple independent sources — see methodology. We are not affiliated with the shoe or clothing brands we write about.
Tools: size converter, brand comparisons, clothes guides, Pinterest pin ideas.
